Retrieval of volcanic SO2 from HIRS/2 using optimal estimation

Abstract:

We present an optimal-estimation (OE) retrieval scheme for stratospheric sulfur dioxide from the High-Resolution Infrared Radiation Sounder 2 (HIRS/2) instruments on the NOAA and MetOp platforms, an infrared radiometer that has been operational since 1979. This algorithm is an improvement upon a previous method based on channel brightness temperature differences, which demonstrated the potential for monitoring volcanic SO 2 using HIRS/2. The Prata method is fast but of limited accuracy. This ...
