Abstract
Using data from the OMI (Aura) satellite instrument, the weekly cycles in the regional atmospheric contents of formaldehyde (CH2O) and nitrogen dioxide (NO2) over European Russia (ER) and Western Siberia (WS) are investigated. The weekly signals in the regional CH2O content are found to be in the opposite phase over ER and WS, but in phase with the weekly signals in the regional surface temperatures in the corresponding regions. Contrary with CH2O, the weekly signals in the regional NO2 content over ER and WS are in phase, manifesting themselves as the "weekend effects" with minima on Sunday and maxima on weekdays. The antiphase weekly signals in the regional CH2O contents over ER and WS can be associated with the dependence of biogenic isoprene emission on the regional surface temperature, influenced by the long Rossby-type waves.
