A composite of the effects of major sudden stratospheric warming events on carbon dioxide radiative cooling in the mesosphere-lower-thermosphere
Akash Kumar, MV Sunil Krishna, Alok K Ranjan
The major sudden stratospheric warming (SSW) events strongly influence the mean structure of the entire atmosphere, from the troposphere to the thermosphere. These events disrupt t…

Effect of 2009 major SSW event on the mesospheric CO2 cooling
Akash Kumar, MV Sunil Krishna, Alok K Ranjan
Carbon dioxide (CO2), an important trace species that is gradually increasing in the atmosphere due to anthropogenic activities, causes enhanced warming in the lower atmosphere. Th…
