|Abstract: ||The spectrometer SCIAMACHY (SCanning Imaging
Absorption spectroMeter for Atmospheric CHartographY) on-board ENVISAT is measuring solar irradiances
and Earthshine radiances from the UV to the NIR spectral
region in nadir, limb and lunar/solar occultation geometry.
Solar occultation measurement are performed during sunrise at northern latitudes (49N to 69N, depending on season). Using an optimal estimation approach with the radiative transfer and retrieval code SCIATRAN 2.1, these
measurements are used to derive vertical profiles of ozone
and NO2. Precise tangent height information is derived
from the scanning over the solar disk. Here we present
an almost complete dataset from August 2002 to December 2006, including validation results with independent
measurements from other satellites.|
