Product Description

The Advanced Very High Resolution Radiometer (AVHRR) provides four- to six-band multispectral data from the NOAA polar-orbiting satellite series. There is fairly continuous global coverage since June 1979, with morning and afternoon acquisitions available. The resolution is 1.1 kilometer at nadir.

The number of available bands will depend on the satellite:

Satellite # Dates Pass # of bands
NOAA-6 6/79 - 11/86 am 4
NOAA-7 8/81 - 6/86 pm 5
NOAA-8 5/83 - 10/85 am 4
NOAA-9 2/85 - 11/88 pm 5
NOAA-10 11/86 - 9/91 am 4
NOAA-11 11/88 - 9/94 pm 5
NOAA-12 5/91 - 12/94 am 5
NOAA-13 failed pm n/a
NOAA-14 12/94 - present pm 5
NOAA-15 5/98 - present am 5
NOAA-16 9/00 - present pm 6

There are two levels of correction available:

  • Raw (Level 1b) is AVHRR data with radiometric calibration coefficients and earth location data appended but not applied. There are two types of Level 1B data available:

    • Single-Scene AVHRR data consists of a single scene that was collected by a single AVHRR satellite on a specific date and time. The approximate scene size is 2400 x 6400 kilometers (1491 x 4000 miles). The data is available from the USGS/EROS Data Center (EDC) to approved USGS researchers only, and is provided in binary (10-bit packed) format on 8-mm tape. Public distribution is via the NOAA Satellite Active Archive.

    • Stitched Orbital Segments consist of single-scene AVHRR data stitched together within an orbit, and is available for limited dates only. Each segment is composed of five channels with a resolution of 1.1 kilometers at nadir. The data is provided in binary (10-bit packed) format, and is distributed on 8-mm tape and via FTP download.

  • Georegistered (Level 1b) Single-Scene AVHRR is radiometrically and geometrically corrected single-scene AVHRR data that is processed according to user-specified parameters such as projection, resampling method, and pixel size. The data is available in binary (8- or 10-bit) format, and is distributed on CD-ROM or DVD.

In addition to the AVHRR data listed above, the USGS also produces a series of derived AVHRR NDVI composites and Global Land Cover Characterization (GLCC) data.
