On October 21, GHGSat released a free map by the name Pulse. Its purpose is to show average methane concentrations every week across the world. The resolution is around two kilometers per pixel. It also shows how the concentrations have changed. The measurements are in parts per either million or billion for every pixel each year.
According to GHGSat founder and CEO Stephane Germain, its purpose is to create awareness to discuss and ask questions about the same. In addition to that, it wouldn’t help in the attributions of emissions coming from specific areas or the identification of hotspots. However, one can get imagery of up to 25 meters at a price if they want more detail.
Companies, as well as government agencies, have been outsourcing GHGSat to help them identify methane sources. The company is open to offer the same for people looking for emission sources, and hotspots added Germain.
The company not only detects but also measures greenhouse gas emissions globally. It achieves that using two satellites, namely Claire and Iris, and the satellites’ launching happened in 2016 and September 2020 for the former and latter, respectively. The next launch will be the Hugo methane satellite on SpaceX Falcon 9 come December. As far as the future is concerned, the Toronto-based company wants to have increased the number to 10 soon. Germain said that it is the ideal number if the company wants to offer customers with regular measurements.
While creating Pulse, GHGSat sources of data were its satellites and other satellites belonging to European Space Agency (ESA), National Aeronautics and Space Administration (NASA), and Japan Aerospace Exploration Agency (JAXA). Such governmental satellites enabled the company to get data globally and daily. However, they have to integrate theirs for a better resolution. Consequently, they would have a lot of data without compromising accuracy.
According to the president’s science advisor at the Canadian Space Agency, Sara Gallagher, Pulse would be a great tool in reducing methane emissions. She added that methane is 84 times worse than carbon dioxide in matters relating to global warming. Therefore, there is a need to identify the time, place, and causes of methane emissions. After all, the reduction of such emissions is a step closer to solving the climate change problem.
During the creation of Pulse, GHGSat chose Claire as the only source of data. However, as the company releases new versions, it will include Iris too. The idea of a methane map came to light in Davos, Switzerland, during January’s World Economic Forum. Then, GHGSat said that its release would occur before the 26th Conference of Parties during the United Nations Climate Change Conference. Before the interruptions of the global pandemic, its date was November 19 at Glasgow, Scotland. However, it will happen in November 2021.
