A "one-size-fits-all" model to predict the effects of climate change on savanna vegetation isn't as effective as examining individual savannas by continent, according to research published in Science ...

First map of vegetation across Antarctica reveals a battle for the continent's changing landscape
Vegetation indices are used to remotely examine vegetation over a given area. One commonly-used index is the Normalized Difference Vegetation Index (NDVI), which uses the difference between near-infrared (NIR) and red reflectance from the Earth's surface, divided by their sum. In healthy photosynthesizing plants, chlorophyll - the main pigment involved in photosynthesis - strongly reflects NIR ...
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 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).
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.
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 reported within ...
