Advanced Very High Resolution Radiometer (AVHRR) Web Subsetting Tool

The Advanced Very High Resolution Radiometer (AVHRR) is a broad-band, four or five channel (depending on the model) scanner, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum. This sensor is carried on the National Oceanic and Atmospheric Administration's (NOAA's) Polar Orbiting Environmental Satellites (POES), beginning with TIROS-N in 1978.

The AVHRR Product generator is an application designed to improve the process of requesting and receiving data from a database of L1B images. The process involves four easy steps: temporal search, profile creation/search, product request, and retrieval of the finished product. The database of L1B images now contains AVHRR data for the West Coast of North America from June 1999 to present. Earlier AVHRR data back to October 1993 can be retrieved upon request from archives.

Anyone with access to the web can use a web browser to search the metadata and request a spatial and/or spectral subset of an image. The image is then delivered to the user in the requested format via an email message that includes a universal resource locator (url), or Web address, from which the image can be viewed and/or downloaded.
