The third generation Global Vegetation Index (GVI) weekly composite data are produced operationally by NOAA/NESDIS and includes conversion of counts to reflectances and brightness temperatures using the post-launch calibration and non-linearity correction coefficients. Cloud flags are generated and appended to each map cell. The GVI dataset represents a sample of Global Area Coverage (GAC) observations mapped into 0.144 degree resolution maps in equal-angle projection (Plate Carree). A 7-day composite is a mosaic of observations produced by retaining data for each map cell corresponding to the maximum difference between AVHRR channels 2 and 1. Normalized Difference Vegetation Index (NDVI) is calculated from AVHRR channel 2 and 1 reflectances using the following formula: NDVI = (CH2 - CH1) / (CH2 + CH1)
