The following validation report by Simon Carn (MTU), prepared in collaboration with NA. Krotkov, K.Yang (NASA) and F. Prata (NILU) gives a comparison between operational OMI SO2 columns derived from the linear fit algorithm (Yang et al., 2007) and infrared (IR) SO2 measurements derived from the Atmospheric Infrared Sounder (AIRS) instrument on the Aqua satellite (Prata and Bernardo, 2007).
