The way Bangladesh is connected to the World Wide Lightning Location Network

The way Bangladesh is connected to the World Wide Lightning Location Network

Dr. My first acquaintance with Sampad Pandey was in 2016. I was then at Frederick University in Cyprus. I am pursuing a PhD in astronomy with the Erasmus Mundus Scholarship under the supervision of Harris Harlambus. Meanwhile, Dr. from India. Resources Pandey and Dr. Sharat Tripathi came to work on two different research projects for three months. A laboratory has been set up for them in a new room near the university. Dr. sitting there. Resources studied the bottom of the ionosphere and said. Sarat Tripathi works with solar flares or solar flares. Two more have already come from India with the allotted scholarships. A Kerala Dr. Tiju Joseph; Another Bengali babu from Kolkata, Dr. Tanmoy Das. Leki Darji, a civil engineering teacher from Bhutan, His project is to explore the response of space’s constantly changing weather or space weather to the Satellite System (GNSS) on Global. Everyone has a lot of fun together. One day cooking is arranged in each person’s flat and sitting together fills the stomach. On weekends we all travel happily from one end of Cyprus to the other. The happy days are over, the farewell bell rings. See you again, we say goodbye to each other.

Three years later. From September 2 to 13, 2019, there will be a two-week workshop on the International Reference Ionosphere in Cyprus . Organizing Committee, for Space Research invited Frederick University. Two general joint-presidents: a well-known NASA researcher. Dieter Bilitza, another is my PhD supervisor. Harris Harlambus. Dr. I knew about Harris’s well-being long ago. “A few students will be taken, so make the application quite neat. At the same time, I will conduct a final examination for your thesis defense, so there is no need to ask for a travel grant. ” Harris let me know in advance. Gurubakya is the title. On August 4, 2019. I received an invitation message from Dieter Bilitzer. He has selected 36 people from more than 100 applicants from different parts of the world. That list said. Wealth is also in Pandey..........................

Finally we met again. The day was September 1, 2019. I and Dr. Wealthy Pandey sat in the open air in Solomon Square in Nicosia, the capital of Cyprus, and got into the story. Dr. is from Nigeria. Moses. This time when he came to Cyprus, after immigration to Larnaca airport Peruno said. First meeting and acquaintance with Moses. He breathed a sigh of relief when he heard that I was going to attend the same workshop. In one of the gaps in the story. Sampad Pandey gave us a grand idea about the World Wide Lightning Location Network. “I have received the necessary tools and equipment to include my university in this project. Professor Robert Holzworth of the University of Washington is the director of the project. My research contract with him has been completed. You can also include your university in this project. Then we will have a field of integrated research. “

Over the past decade since 2009, the World Wide Lightning Location Network has been continuously identifying lightning around the world, as well as determining the location, timing and intensity of lightning. The Department of Earth and Space Sciences at the University of Washington operates the network by setting up sensor stations in various parts of the world with equipment developed in its own laboratory. When lightning strikes a place, a kind of very low frequency wave is emitted from it. The name of this wave is Spherix. Although very small, this wave has a strange ability. If we imagine the space between the surface of the earth and the bottom of the ionosphere as a huge tunnel, However, through that tunnel, this spherix can instantly run from one end of the earth to the other. So it is possible to detect spherics by placing sensor stations anywhere in the world. But it is not possible to do the job thoroughly with a single sensor station. A combined effort of at least five stations is required. The magnitude of the lightning at this moment, but according to the rules, none of us know. However, it is possible to determine a proportional rate between the waves recorded at the sensor station at two different distances from that location. Thus a review of the proportional rates of more than two sensor stations shows that it has a close relationship with the distances of the stations. This relationship is the key to determining the location of lightning. Before the spheres reach a sensor station near the lightning; And will reach the remote station very little later. Now if we observe this Time of Group Arrival (TOGA) with five stations, it is possible to determine the time of lightning. The most important thing is that if it is possible to determine the place, time and intensity of lightning, they can be put into a fine prediction model to make a global picture of future lightning, which is useful to us.

I sent the first email to Professor Robert Holzworth on October 6, 2020. Wrote, “I am a tiny researcher; At present, I am dedicated to unveiling the character of the ionosphere in Bangladesh. I would like to host a sensor station to connect Bangladesh to the World Wide Lightning Location Network. Lightning is a terrible natural disaster in our country. The Government of the People’s Republic of Bangladesh has been taking effective measures to deal with this disaster in our country with due importance. At the same time, it is encouraging research in this regard. As far as I know, there is no station of this network in Bangladesh till now. If a station is set up here, the world will get data on lightning discharges around Bangladesh, so we will have access to data from 60 stations around the world, including Bangladesh, for research. ”

The answer came the next day. Professor Holzworth wrote, “Thank you for your interest in the World Wide Lightning Location Network. One of our stations in Tripura, just 160 km from Dhaka, has been running for many years. Usually we do not invest for another station within 500 km. But if you want to make your own hardware and host a station, we can send you a circuit diagram. ” I fell into thought. Looking at the circuit diagrams in our lab, it is quite a challenge to make these fine sized instruments. Moreover, the world was in a state of panic at the time of Pandemic. At the moment the focus of our organization is different.

He looked like Hari Ghosh described on the very first page of Manik Bandyopadhyay’s “Puppet Dance Itikatha”. “Haru Ghosh was leaning against a huge banyan tree by the canal. The god of the sky looked at him and looked at him.”

Don’t give up hope. I decided in my mind, I will present the matter again with some more information and argument with more politeness. We collect data on the frequency and intensity of lightning in Bangladesh for the last ten years. Five days later I emailed the professor again. Arguing, “I am very respectful of your monetary policy. However, Madhupur, which is located near Dhaka; The area is one of the lightning prone areas in the whole of South-East India. So I think if a sensor station is set up near this area, those who are doing research on lightning around the world will have the opportunity to do research on a delicate situation. This will make it possible to design more efficient and powerful lightning insulation systems in the future. I urge you to reconsider and reconsider my request. ” I am waiting for the reply.

The answer finally came eight days later. August 20, 2020, at four minutes past four in the morning. “Dear Md. Golam Mostafa, I have discussed your request with colleagues and we have agreed that setting up a station there would benefit the World Wide Lightning Location Network; Although there is another station in our network (Tripura) just 100 km from your proposed area. So come on, let’s get to know the terms and conditions of the agreement we will be making with you to get involved in this work. This is not just a research agreement between you and me as a scientist; There is also a Memorandum of Understanding between you and my University, under which you and I will be committed to carrying out joint research activities. We can get rid of this agreement at any time and you and my university will not be liable for it. ”

Then a detailed agreement of several pages is affixed. As soon as possible I brought the matter to the notice of my university authorities. After analyzing the advantages and disadvantages of the agreement, the appropriate authorities informed me of their formal positive decision in this regard and assured me of their full cooperation. And without delay I emailed Professor Holzworth informing us of our decision. By then, the epidemic had intensified.

Days go by, months go by, years go by! The answer does not come. The new year comes, but not yet. Four days into the new year, Professor Holzworth is reminded of his New Year’s greetings. Write, “Dear Professor, Happy New Year to the Gregorian calendar. I apologize for this gentle reminder, if my previous email did not appear to you. Again, we gladly agree to the terms of your agreement. Top executives of our organization have already allocated the necessary budget to take this project forward. I am again providing your address to send your promised equipment. I look forward to hearing from you soon. ” Within five hours, the reply came, “Dear Mustafa, I have received your email. I’m sorry, Covid has stifled everything. Hopefully by the end of January I can send you the promised equipment. Sincerely, Bob. ”

January goes to February, March comes. Equipment is not shipment. In the meantime, formal professor Robert Holzworth has become an informal bob to me. So I took the opportunity to send him a memoir addressing him as Bob. The reply to the memo came quickly, “Dear Mostafa, yes we are a little late, I am sending you the equipment by the end of this month. I can tell you the reasons for the delay in writing. But those are annoying. Some employees have medical issues and covid issues. ”

March is gone, TS Elliott’s cruelest month is gone, and when they have a flower ceremony there in May, I write again, “Dear Bob, take a look at the sources in my previous emails. I gave you a gentle reminder. ” This time the answer is also immediate. “Dear Mustafa, our situation has changed here. I need a few more days to place your request. We have to do equipment replacement to keep several stations on our current network running. So you have to wait until next August when the new batch of equipment is ready. You can keep in touch with me regularly to be aware of the situation. I’m sorry to have waited so long for you. “

The mind dies, but hope never dies. The month of August brought a river of excruciating pain to my life. The agonizing burden of the agony of fatherlessness created a perpetually intense burning wound of cold fire deep in my chest. But still the pace of life continues beyond the valley of death. September comes, at the beginning of the month I put my finger on the black keyboard to type Bob again. This time too the immediate answer was, “Dear Mostafa, I am sorry for the constant delay. You are the next person on my list. Hopefully next week. Re-enter your address for FedEx. Along with your local phone number and all the paperwork required for customs clearance. We will send you a complete list of equipment with the package, Itemized. This package has no commercial value. We are donating these tools to your institute to join our network. ” I immediately sent the address and phone number. The next day the tracking note came from FedEx. They picked up my package.

The package arrived at Dhaka Customs. Now it’s time to redeem. Sometimes the hand of help extends even from the most unexpected and unexpected place. Additional Commissioner of Dhaka Customs came forward. Mahbub. He took up the responsibility of unloading the goods from his professional responsibilities. Anuj and Snehabhajan Mahbub and I were both BUET students. “Brother Mostafa, your package has been released and is now in my office. Take an invitation to have tea today. ” I immediately informed the head of the department. He accompanied the pike-pedestrian. The administrative director sent the car as soon as he found out. This time ‘Mard walked on horseback’. After understanding the package from the customs, I returned to the lab in a good mood. I bought copper wire for the equipment and earthing needed to fit the antenna along the way. Bought standard multiplugs and sockets. I bought an online UPS before, For uninterrupted power supply. I don’t want data to be lost during load shedding or sudden power outages. When I returned home satisfied with everything, I kept my eyes on the sky. I could not understand when the sun began to spread a pink glow in the twilight sky.

The work of setting up the equipment started from the next day. The smallest frequency (3 to 30 kHz) wave emitted from lightning is called spherics or radio atmosphere. Many call it a whistle because it sounds like a whistle. Bob sent a very low frequency (VLF) antenna and a VLF receiver to capture this wave. The sound wave will be caught on the antenna and the receiver will invite him and bring him home. But it is very difficult for the receiver to detect this very weak wave. So a pre-amplifier has to be placed between the antenna and the receiver to make it stronger to an acceptable level. Bob sent that too. The wavelength of spherics is within the limits of sound waves. So a commonly used sound card is able to capture it and save it to a computer. Bob sent a raspberry pie computer with a sound card. It also has a microSD card; Computer memory. This is the system in bold. I need a broadband internet connection to send data over the network. A keyboard and a rat to input into the Raspberry Pi; A monitor for viewing the output. At the request of the ICT director, everything was arranged at an incredible speed. Absolutely at lightning speed; ‘Fast and sure’. By connecting one to the other I set up the system. Now it is the turn of placing the antenna in the appropriate place. So that Spherix Babaji comes down to the antenna safely like a sparrow sitting in a nest. Bob had already pointed out the method. A good headphone will fit in the sound port. Keep your right ear closed and listen to your left ear while walking on the roof with the antenna. Where the sound of the whistle is most clearly heard, That is the place of salvation. I came to the roof. I am walking according to the instructions. Many people are standing behind me and watching my activities from a distance. It is the responsibility of the reader to guess at the kind of smile that appears on the corners of their lips when they see the actions of a mad scientist. Finally, a clearer whistle blew; The sound of the drill instructor’s unforgivable whistle came to my ears during the military training.

I slowly pressed the raspberry pie computer button. After a while, a picture of raspberry pie in three toasts appeared on the monitor screen. Then the Login dialog box. There are three options to login. No problem guessing, I have to login as host. That is what I selected. The computer asked for the password this time. Difficult, where do I get the password now? Want to know by email to Bob? My time interval with him is 12 hours. The poor man must have slept all day and must be sleeping now.

I emailed Bob before going to bed at 12 o’clock at night. Write, “You wanted to send me a list of TCP / UDP ports, and some IP addresses; So that the new station established in Bangladesh can enter your network. Also, did you send me a password to login as a host? ” At three o’clock in the morning the cellphone rang. I see, Bob’s message has arrived. Six IP addresses and three TCP / UDP ports for data tunneling. Separately sent the password in another message; Please do not reply to or forward this email for password protection. The next day I entered the university and went straight to the lab. I login by pressing the Raspberry Pi button. I already memorized the password; Aladdin came to the door of the cave with infinite excitement and said in an expression, ‘Sisim gap’, His face lit up a little in my eyes. The door opens. Go to Google as Bob said, go to CNN. Understood, my computer is talking to the outside world. In that case, according to the information sent by Bob, my computer should set up an automatic reverse tunnel with his system. I emailed Bob, “See if you can find us?” The answer comes, at 8:25 pm on September 23, “No, Mostafa, I don’t see your station in our Flash 2 tunnel data. I sent you another port. Try contacting this port. Holidays on 25th and 26th, lab closed. The next day, on September 26, he tried to contact the port again. I failed every time. In this way, Furolo on 26 September. With a broken heart, I emailed Bob, “Bob, I’m getting Google, CNN; But not communicating with your system. Let’s see if there is a problem with your end. ” My computer is talking to the outside world. In that case, according to the information sent by Bob, my computer should set up an automatic reverse tunnel with his system. I emailed Bob, “See if you can find us?” The answer comes, at 8:25 pm on September 23, “No, Mostafa, I don’t see your station in our Flash 2 tunnel data. I sent you another port.

Let’s see if there is a problem with your end. ” Getting CNN; But not communicating with your system. Let’s see if there is a problem with your end. ”

September 29, 2021. Bob’s email arrives at five-sixteen in the morning. “Dear Mostafa, success! We were able to connect your computer to us. Now it is necessary to connect the receiver with VLF antenna to your computer so that the sound waves from there can travel smoothly to our end. We’re not getting any spheres from you right now. This is usually a preamplifier if not properly connected to the receiver. As soon as we start getting uninterrupted streams of good quality Spherix sound waves we will set up the program to save them to our backup server in New Zealand. After a week or two of confirming their accuracy, we will fully integrate them with the data stream of the World Wide Lightning Location Network. Really great as a start! Look at this Spectogram of this moment of your station. No VLF data is showing yet. ” I see another email from James Brundell in Bob’s email thread. It read, “Hi Bob! It seems to be working now, right? There is a station online at port 26035, I can see. Bangladesh is showing place in GPS. That’s it, James. ” I mean, not all success came.
