Vegetation Near Real-Time Data - NASA Earthdata Vegetation Near Real-Time Data Near real-time data provided by NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE) can be used to monitor vegetation and crop conditions
Vegetation Index - NASA Earthdata Vegetation indices measure the amount of green vegetation over a given area and can be used to assess vegetation health NASA’s Earth-observing satellites collect several different vegetation indices, including Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Leaf Area Index (LAI), and Fraction of Photosynthetically Active Radiation (FPAR)
MODIS Terra Vegetation Continuous Fields Yearly L3 Global . . . - Earthdata The MOD44B Version 6 1 Vegetation Continuous Fields (VCF) yearly product is a global representation of surface vegetation cover as gradations of three ground cover components: percent tree cover, percent non-tree cover, and percent non-vegetated (bare) VCF products provide a continuous, quantitative portrayal of land surface cover at 250 meter (m) pixel resolution, with a sub-pixel depiction
Use Remote Sensing Data to Study Vegetation Dynamics Overview Remote sensing data can be used to study vegetation dynamics, such as plant healthiness Like all objects, plants have unique spectral characteristics, and this information can be interpreted from remote sensing data to determine a plant’s condition
Normalized Difference Vegetation Index (NDVI) | NASA Earthdata Vegetation indices measure the amount of green vegetation over a given area and can be used to assess vegetation health A commonly-used vegetation index is the Normalized Difference Vegetation Index (NDVI), which uses the difference between near-infrared (NIR) and red reflectance divided by their sum

Global Vegetation Greenness (NDVI) from AVHRR GIMMS-3G+, 1981-2022 Description This dataset holds the Global Inventory Modeling and Mapping Studies-3rd Generation V1 2 (GIMMS-3G+) data for the Normalized Difference Vegetation Index (NDVI) NDVI was based on corrected and calibrated measurements from Advanced Very High Resolution Radiometer (AVHRR) data with a spatial resolution of 0 0833 degree and global coverage for 1982 to 2022 Maximum NDVI values are
The Harmonized Landsat Sentinel-2 Project Releases Vegetation Indices NASA’s Harmonized Landsat and Sentinel-2 (HLS) project released two new products, the Landsat 30-meter Vegetation Index (HLSL30VI) and Sentinel-2 30-meter Vegetation Index (HLSSS30VI) Each product contains a suite of nine vegetation indices including greenness, vegetative moisture content, burned area, and vegetation change (see below for a full list of indices available)
MODIS Terra Vegetation Indices Monthly L3 Global 0. 05Deg CMG V006 . . . The second vegetation layer is the Enhanced Vegetation Index (EVI), which has improved sensitivity over high biomass regions The Climate Modeling Grid (CMG) consists of 3,600 rows and 7,200 columns of 5,600 meter (m) pixels
