Summary
The method to determine satellite derived surface albedos as already described by Preuß and Geleyn [1] is applied with some minor modifications to the longer and denser data set of planetary albedos measured by NOAA-4 from June 1975 to May 1976. The resulting surface albedos are, as far as one can judge, of better quality than the previous ones and have therefore replaced them in operational use at ECMWF in December 1982.
Zusammenfassung
Die Methode zur Ableitung der Bodenalbedo aus Satellitenmessungen nach Preuß und Geleyn [1] wird mit kleinen Änderungen auf einen längeren Datensatz mit höherer räumlicher Auflösung (NOAA-4, Juni 1975 – Mai 1976) angewandt. Die resultierenden Bodenalbeden zeichnen sich durch eine bessere Qualität aus und werden seit Dezember 1982 im operationellen Vorhersagesystem des EZMW verwendet.
