Scientists from the Chinese Academy of Sciences compiled an unusual map based on data from a special satellite TanSat. Since 2016, instruments on board have collected data across the entire electromagnetic spectrum in order to identify carbon dioxide accumulations in the planet's atmosphere. The satellite is specially placed in a sun-synchronous orbit to always work on illuminated areas of the Earth.

The head of the research team, Jan Dunshu, says – they can not measure the CO2 concentration at an arbitrary point in the atmosphere, but the satellite does well to monitor the flow of carbon dioxide. In the future, when additional observation stations are put into orbit, their data can be synchronized and make up the most complete map. But even now there is something to draw conclusions from.

For example, the seasonal decrease in the CO2 concentration in the Northern Hemisphere from spring to summer is well traced, when the rates of photosynthesis in the burgeoning vegetation change. Or you can very accurately indicate the “hot spots”, the places of a strong gas release due to anthropogenic activities in China, the US and Europe. Now businesses will not be able to hide or distort the facts of emissions.

Dunshu explains the importance of research – historically, it was impossible to study the global distribution of carbon dioxide. And those caught in emissions into the atmosphere could always appeal to an argument like “from the neighbors it brought wind”. Now, the data from TanSat will allow interested parties to conduct a dialogue in a different direction, besides, it will help in future climate research in general.
