In-orbit calibration of Meteosat and its possible extension to other applications and fields.
Abstract
The problem of radiometric calibration is discussed. Attention is given to the 'black body' standard of calibration and problems with its implementation, noting that individual instrument designs often use different approaches which makes it difficult for a single user to correlate data from different instruments. It is proposed that a calibration technique used for Meteosat, which extracts the necessary calibration data from the moon, be adopted for all similar instruments. In conclusion it is noted that a byproduct of this work is the generation of lunar thermal images, which could provide data of interest on lunar thermal properties.
