  9. Selection of Optimum Cold Calibration Position EUMETSAT Metop-A AMSU-A Cal/Val

  10. 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. .
