Chinese satellite TanSat compiled the first global map of CO2 in the Earth's atmosphere

Scientists from the Chinese Academy of Sciences have compiled an unusual map based on data from the special satellite TanSat. Since 2016, instruments on board have been collecting data across the entire electromagnetic spectrum to reveal the accumulation of carbon dioxide 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 group, Yang Dongxu, says they cannot measure the concentration of CO 2 at an arbitrary point in the atmosphere, but the satellite is good at tracking flows of carbon dioxide. In the future, when additional observation stations are launched into orbit, their data can be synchronized and the most complete map compiled. But even now there is something to draw conclusions from.

For example, a seasonal decrease in the concentration of CO 2 in the Northern Hemisphere from spring to summer is well traced, when the rates of photosynthesis in flowering vegetation change. Or you can very accurately indicate "hot spots", places of strong gas release due to anthropogenic actions in China, the United States and Europe. Now enterprises will not be able to conceal or distort the facts of emissions.

Dongxiu explains the importance of research - historically, it was impossible to study the global distribution of carbon dioxide. And those convicted of emissions into the atmosphere could always appeal to an argument like "it was blown by the wind from the neighbors." Now, the data from TanSat will allow stakeholders to engage in dialogue in a different direction, and it will also help in future climate research in general.
