Eclipse anomalies in atmospheric motion vectors derived from meteosat imagery and their implications on data assimilation

From: Journal of Applied Meteorology | Date: July 1, 2003| Author: | Copyright information

ABSTRACT

This study examines atmospheric motion vectors derived by tracking features in image sequences from Meteosat for anomalies during the second satellite eclipse period of 2001. During eclipse periods (March-April; September-October), data from geostationary sensors are prone to anomalies caused by solar stray light entering the radiometer around local midnight. As a result, imagery from geostationary satellites can exhibit local anomalies for certain time slots, and these anomalies can change considerably from one time slot to the next. The effect of these anomalies on atmospheric ...
