Paper Abstract

We present the results of the first in-flight spectral calibration of the ENVISAT/MERIS instrument. An operational algorithm using the high sensitivity of absorption to the spectral location in the O2 bands is briefly presented. We show that an accuracy of ± 0.02 nm can be reached with a careful analysis of the whole dataset. This method was successfully compared to other techniques and proved to have the lowest noise. Consequences for the MERIS Surface Pressure product are investigated and optimization of the O2 bands setting is proposed.
