Metop-A AMSU-A Cal/Val


Selection of Optimum Cold Calibration Position

EUMETSAT

Metop-A AMSU-A Cal/Val


Summary

● Overall AMSU-A calibration is good with most of the quality control flags being properly set

● On-orbit AMSU-A NET at all channels meets specification

● Missing data: whole orbits(?)

● No overlapping between orbits, but have gaps ~5 min

● METOP-A has base-plates with temperatures controlled.
