IMPROVEMENTS TO THE RETRIEVAL OF NOsub2/sub COLUMN FOR THE GOME-2 INSTRUMENT

摘要

NOsub2/sub is an important trace gas in both the stratosphere and troposphere. Since January 2007, the nadir-looking GOME-2 satellite instrument has been providing NOsub2/sub data on a global scale which is of great interest for climate research and atmospheric chemistry studies. In this contribution, we report on an improved algorithm for the retrieval of total and tropospheric NOsub2/sub columns from the GOME-2 instrument.
