SCIAMACHY: Level 2 vertical columns of trace gases products version 5.02

Level 2 data (vertical columns of trace gases) from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY). SCHIAMACHY was one of the ten instruments on-board the Envisat satellite launched from Kourou (French Guyana) on the 28th of February 2002. Envisat was operated by the European Space Agency (ESA) until May 2012. SCIAMACHY was used to provide global measurements of trace gases in the troposphere and the stratosphere. These data are calculated using the radiance observations and known absorption spectra of such gases. Fully reprocessed Level 2 data is available, with samples of near-real-time (nrt) and consolidated (result of a first processing by ESA to eliminate bad data and perform a few basic checks) data.
