GOME (ESR-2 Sensor)

Global Ozone Monitoring Experiment

GOME is a passive double spectrometer, developed to measure tropospheric and stratospheric trace gases with particular emphasis on global ozone distribution. The main scientific objective is the global measurement of these trace gases. Additionaly aerosols, cloud-top heights and surface reflection can be measured. The "differential optical absorption spectroscopy"-technique (DOAS) is used to retrieve the amount of atmospheric trace gases.

GOME is an ESA instrument jointly designed by Germany and the Netherlands. PI is J. P. Burrows, Univ. Bremen.
