GIMMS Global Agricultural Monitoring


Use the GIMMS Global Agricultural Monitoring (GLAM) interface to view MODIS & VIIRS NDVI imagery and retrieve MODIS & VIIRS NDVI time series data. The GIMMS GLAM system provides near real-time and science quality Terra and Aqua MODIS & NPP VIIRS 8-day composited, global NDVI datasets. These datasets are derived from the Collection 6.1 MOD09/MYD09 and Collection 1 VNP09 surface reflectance products which are provided by NASA/GSFC/EOSDIS LANCE and NASA/GSFC MODAPS.

The GIMMS/GLAM system is developed and provided by the NASA/GSFC/GIMMS group for the USDA/FAS/IPAD Global Agricultural Monitoring project. The USDA/FAS/IPAD mission is to provide objective, timely, and regular assessment of the global agricultural production outlook and conditions affecting global food security.

The GIMMS Global Agricultural Monitoring (GLAM) System is funded through an interagency agreement grant between USDA/FAS/OGA and NASA/GSFC.

We acknowledge the use of data products from the Land, Atmosphere Near real-time Capability for EOS (LANCE) system operated by the NASA/GSFC/Earth Science Data and Information System (ESDIS) with funding provided by NASA/HQ.

The MODIS & VIIRS Surface Reflectance 8-Day L3 Global 250m and 500m datasets are acquired from the Level-1 & Atmosphere Archive and Distribution System (LAADS) Distributed Active Archive Center (DAAC), located in the Goddard Space Flight Center in Greenbelt, Maryland (
