N2O maps

by EarthdataForumContributor » Thu Apr 23, 2020 1:02 pm America/New_York

How can I download N2O maps for all of 2019 as referred to in the article (BBC news) am trying to correlate N2O concentrations to the Corona Virus outbreak in Wuhan China in 2019 but I need all of the N2O maps for 2019. It looks as though N2O concentrations came down due to changing weather patterns (or other reason) several months before the outbreak. This correlation data I will be sending to the CDC because it may help them understand what atmospheric conditions around the world may be speeding up transmission such as areas with lower or higher N2O.Thanks. Your speedy response would be very much appreciated.

TES ceased to take measurements in Jan 2018.
(Even if TES were still operating, we would not recommend the use of a spaceborne N2O product to try to infer anything about variations in N2O at the surface. Thermal IT instruments such as TES, AIRS, CrIS and IASI are primarily sensitive to variations of N2O in the mid to upper troposphere.)

But we assume that you are looking for NO2 maps, not N2O.
We use http://www.temis.nl/airpollution/no2col/no2regio_tropomi.php to view NO2 maps from TropOMI.
