Global EVI derived from AVHRR, SPOT, and MODIS 1981-present
Entry ID: MEaSUREs_VIP_EVI

[ Update this Record ]

Summary
Abstract: MEaSUREs VIP Enhanced Vegetation Index products are supported by a NASA Making Earth Science Data Records for Use in Research Environments (MEaSUREs) collaborative agreement. The EVI is a two-band VI developed as a consistent, high quality, and well characterized Earth Science Data Record (ESDR) using long term data from multiple satellites in support of global change studies. In collaboration with researchers at Boston University, University of Hawaii, NOAA/ERT Inc., and the USGS-EROS LP-DAAC, an end to end system is currently being developed to support science algorithms that derive consistent EVI from AVHRR, SPOT, MODIS, and eventually VIIRS. The project includes validation and quality assurance analysis of these ESDRs in collaboration with the US-National Phenology Network (US-NPN) and the US-Southwest Regional Phenology Network (US-SWRPN).

Purpose: Long term, consistent, and high quality vegetation records enable climate change study, and land surface change characterization. The MEaSUREs VIP EVI product enhances the performance of NASA MODIS algorithms (MOD13) by calculating EVI without the use of the blue band. The result minimizes adverse reactions known in NDVI products to dense vegetation, sparse vegetation, and background signals.
