  author={Garik Gutman and Alexander Ignatov and Steve Olson},
Abstract Global Vegetation Index (GVI) time series of multispectral AVHRR weekly composite data with a 0.15° resolution have been collected from NOAA-9 and -11 since 1985. A prototype global land monitoring system was developed based on monthly maps of standardized anomalies of satellite derived Normalized Difference Vegetation Index, NDVI, and Channel 4 brightness temperature, T 4 . Processing included post-launch updated calibration and cloud screening, filling in the cloud induced gaps by… CONTINUE READING
