Improve sea ice classification based on Synthetic Aperture Radar (SAR), scatterometers and passive microwave (PMW) sensors.

The primary sources of the post-1972 data are the hemispheric fields of sea - ice concentration from (1) the U.S. National Ice Center (NIC), whose weekly grids (derived primarily from satellite data) span the period 1972 - 1994, and (2) the satellite passive - microwave grids from the Scanning Multichannel Microwave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and othermicrowave grids from the Scanning Multichannel Microwave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and otherMicrowave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and otherMicrowave / Imager (SSM / I) period, 1978 - 97 (Parkinson and others, 1999).

Sea ice concentration, which is independently measured and well observed by passive microwave satellite sensors, gives additional important information on changes in the Antarctic environment.

The passive - microwave data used for the Sea Ice Index is especially helpful because the sensor can «see» through clouds and deliver data even during the six months of Arctic darkness and frequently cloudy conditions.

Some participants expressed concern that a capability for passive microwave precipitation measurements may not emerge in the revised MIS sensor, and they suggested that NPOESS place emphasis on the water cycle (water vapor, liquid water, ice water, and precipitation) when considering MIS requirements, possibly including giant magneto - impedance (GMI) bands.
