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.
