Products and Datasets

Collection of licensed commercial imagery from various vendors. Available to government agencies only.

Weekly and biweekly NDVI composites based on 1-km AVHRR data (1989 to 2019). To all users of AVHRR composites. The NOAA 19 satellite which currently supports the AVHRR sensor has been degrading in orbit to the point where the nadir view is on the day night terminator within its orbit.

This collection of test sites provides critical information on the post launch characterization and calibration of space-based optical imaging sensors to assist the global science community in providing more accurate land/climate studies.(1972 to present).

1-km multispectral data from the NOAA satellite series. (1979 to 2019) To all users of AVHRR composites. The NOAA 19 satellite which currently supports the AVHRR sensor has been degrading in orbit to the point where the nadir view is on the day night terminator within its orbit.

The U.S. Antarctic Resource Center (USARC) maintains a collection of Antarctic maps and charts with flight lines to identify coverage for aerial photographic missions. (1946 - 2000)

Orbital Pass Generation Nearly 45,000 individual observations were acquired during the first 30 months of this project. The number of individual scenes and overall data volume, an estimated 4.0 terabytes, are large by contemporary standards. As a result a new process was developed to improve data management.

Background 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 NOAA's Polar Orbiting Environmental Satellites (POES), beginning with TIROS-N in 1978.
