Formaldehyde and nitrogen dioxide in the atmosphere during summer weather extremes and wildfires in European Russia in 2010 and Western Siberia in 2012
2017
Sitnov, S. A. | Mokhov, I. I.
Based on the data from the Ozone Monitoring Instrument (OMI; Aura) satellite instrument, an analysis of changes in total formaldehyde (CH ₂O) column and tropospheric nitrogen dioxide (NO ₂) column, associated with the extreme summer weather regimes and wildfires in European Russia (ER) in 2010 and Western Siberia (WS) in 2012, was carried out. In both territories, over the clusters of intense fires, an approximately two-fold increase in CH ₂O content and a 20% increase in NO ₂ content were observed. Unlike NO ₂, the changes in the CH ₂O content over ER and WS also reveal positive correlation with the regional surface temperature.
