European Contributions to the Remote Sensing of Atmospheric Ozone
and Aerosol Vertical Profiles
Dr. John P. Burrows, University of Bremen, Germany
GOME is a smaller scale version of SCIAMACHY, launched aboard ESA ERS-2 in 1995 and observing only in nadir viewing geometry. SCIAMACHY has now made five years of measurements, since its launch in 2002 aboard Envisat and makes limb, nadir and solar occultation measurements. Recently GOME-2 has been successfully launched aboard Metop A, the first of three ESA/EUMETSAT satellites. GOME and SCIAMACHY make measurements of the solar electromagnetic radiation, back scattered from the earth’s atmosphere. Inversion of these measurements yields columns and vertical profiles of atmospheric constituents: targets being the distributions of trace gases, such as O3, NO2, HCHO, CHO.CHO, BrO, CO, CO2, CH4 and H2O. This talk highlights the significance of the GOME/SCIAMACHY data for tropospheric and climate change research.
