SCIAMACHY and GOME: the scientific objectives

摘要

Abstract: The Global Ozone Monitoring Experiment (GOME) and the scanning imaging absorption spectrometer for atmospheric chartography (SCIAMACHY) are two European experiments which will fly on satellite platforms in the 1990s. GOME is a small scale version of SCIAMACHY and together they form the SCIAMACHY scientific project. The principal scientific objective is the global determination of the distributions of atmospheric constituents: trace gases, aerosol, and cloud. Special emphasis is placed in this project on stratospheric and tropospheric measurements. GOME observes between 240 and 790 nm in nadir sounding, whereas SCIAMACHY will sound the atmosphere in nadir, limb, and solar and lunar occultation viewing geometries between 240 and 2380 nm. !8
