AVHRR Leads-ARI Polar Gridded Brightness Temperatures

IMPORTANT NOTE: Data for 1992 are currently being reprocessed and will be available in the near future. Please contact NSIDC User Services for more information.


Summary

The AVHRR sensor is a broad-band, cross-track scanning instrument that senses in the visible, near-infrared and thermal infrared portions of the electromagnetic spectrum. Depending on the model, the AVHRR is a four or five channel scanner. It has flown continuously on NOAA's Polar Orbiting Environmental Satellites (POES) since 1978 and provides pole-to-pole on board collection of data from all channels. For a description of the Arctic Leads ARI project, please refer to the Project Description document. For a description of the data set, please refer to the Arctic Leads ARI data set documentation.
