The Advanced Microwave Precipitation Radiometer (AMPR) was flown on the NASA ER-2 aircraft during the FIRE-III Arctic Cloud Experiment conducted in May-June, 1998. AMPR is a total power passive microwave radiometer recording passive microwave signals at 10.7, 19.35, 37.1, and 85.5 GHz. These data were collected on the 11 science flights conducted by the ER-2 during the experiment. A major goal of AMPR participation was to show the ability to detect small-scale sea-ice properties in all types of weather conditions indigenous to the Arctic; specifically through cloud cover (stratus-families, fog, etc.) This detection was visually evident immediately from the data collected in the field.
Our presentation will display visual evidence of the sea-ice seen by AMPR along with corresponding satellite information collected by the DMSP F-13 and F-14 Special Sensor Microwave/Imager (SSM/I) and the NOAA-14 and NOAA-15 Advanced Very High Resolution Radiometer (AVHRR). A time history of conditions in the vicinity of the north coast of Alaska and southern Beaufort Sea will also be presented. This history will include changes in area extent of open water/broken-ice/coastal-ice, lead formation and changes in existing leads, movement of broken-ice and coastal-ice.
