Clark Labs offers the global AVHRR NDVI 3g data product in 16-day and monthly composites and the global MODIS monthly NDVI/EVI products. All data are processed for immediate analysis and mapping within the TerrSet software. The data archives are well-suited for Earth Trends Modeler. TerrSet’s Earth Trends Modeler is used to explore and analyze trends and dynamics in image time series data. It is therefore especially useful for those researching global climate change and ecosystem impacts.
All of the data in this series are in IDRISI file format.
Global Data Archive 1: 0.05 Degree MODIS Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) 2000(2) – 2016(6)
