 NDVI composite for May 18-24, 2001 |
Product DescriptionNormalized Difference Vegetation Index (NDVI) Composites are produced from multiple AVHRR daily observations that have been composited together to create a nearly cloud-free image showing maximum greenness. An NDVI ratio is produced from bands one and two of the AVHRR composite to produce a derived NDVI band composite. The following NDVI products are available: Conterminous U.S. and Alaska Weekly and biweekly NDVI composites date from January 1989 to present. U.S. composites are cast to the Lambert Azimuthal Equal-Area projection. Alaska composites are cast to the Albers Equal-Area Conic projection. The data will include a composite for each of the acquired AVHRR bands, as well as a derived NDVI band. The files are available in binary (8-bit) format. Global 10-day composites consist of 10-day composited AVHRR data and a derived NDVI band for limited dates between April 1992 and May 1996. The data is cast to the Interrupted Goode's Homolosine projection. Subsampled resolution and geographic subsets are also available. The files are provided in binary (8-bit) format, and they are distributed via File download on a band-by-band basis. Additional Information: Back to TopDownload
