SCIAMACHY instrument performance calculation and test

摘要

Abstract: SCIAMACHY, the scanning imaging absorption spectrometer for atmospheric cartography on Envisat-1 (1998) measures global distributions of ozone and greenhouse tracegases by employing DOAS and SBUV techniques. As an aid in the development of instrument hardware and data-processing algorithms, an instrument simulator has been developed predicting signal to noise performance. Calculated performance is substantiated by early test results on the optical unit and shows that instrument requirement specifications can be met in most instances. !5
