The AVHRR instrument is used for a wide range of applications in polar and climate research. AVHRR data provide a global, long-term, consistent time series with high spectral and spatial resolution suitable for albedo and surface temperature measurements. Such measurements are necessary for studies involving climate, sea ice distribution and movement, and ice sheet coastal configuration.
Images of Antarctic Ice Shelves
Researchers at NSIDC, funded through The Antarctic Glaciological Data Center (AGDC), monitor ice shelf changes in the Antarctic Peninsula using AVHRR data.
