An automated image analysis system for determining sea-ice concentration and cloud cover from AVHRR images of the Antarctic
The Australian Bureau of Meteorology operates a meteorological centre at the Casey station in East Antarctica. This centre is able to receive Advanced Very High Resolution Radiometer (AVHRR) data directly from the NOAA satellites and the Bureau uses these data for operational and research applicatio...

Currently the AVHRR images are interpreted manually. However, the ICEMAPPER analysis system is able to automate this process. The system uses one set of rules to identify areas of high cloud, low cloud, open water, land ice and sea ice and another to determine sea-ice concentration. Some of the rules in ICEMAPPER were derived using information obtained from published and unpublished research, augmented by details given by practising meteorologists.
