USDA/FAS/NASA/GSFC Vegetation Index Monitor

AVHRR, SPOT Vegetation and MODIS Vegetation Index Anomalies

USDA's Foreign Agricultural Service (FAS) Production and Crop Assessments Division (PECAD) and NASA/GSFC's Global Monitoring and Modeling Systems (GIMMS) group are collaborating in processing and analyzing global vegetation index data from SPOT Vegetation and NOAA-AVHRR satellites for global agricultural monitoring and general environmental monitoring. These data provide a basis for evaluating crop conditions by tracking the growing season dynamics and in the assessment of likely agricultural production at the end of the growing season. In addition derived products are used in drought monitoring and hazards assessment in support of USAID's FEWSNET Program for Africa and Afghanistan. NASA
