Bahramvash-Shams performed a detailed analysis of recent Sudden Stratospheric Warmings (SSW) using the Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) dataset. This study took advantage of the continuous observations provided by the NDACC at five Arctic Infrared working group (IRWG) and ozonesonde stations, where vertical profiles of ozone are routinely measured consistently over the long term.

The Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NM) instruments onboard the Suomi NPP and NOAA-20 satellites have been used to produce a HCHO record from 2012 to the present. Formaldehyde products from the OMPS-NM instruments were recently updated, compared with TROPOMI observations over 12 geographical regions, and validated with NDACC FTIR HCHO observations at 24 ground stations.
