Vegetation Health Index

Update Schedule
Data Valid

NOAA's Center for Satellite Applications and Research produces satellite-based global vegetation health products, including the vegetation health index (VHI). The Vegetation Health Index is a proxy characterizing vegetation health or a combined estimation of moisture and thermal conditions. Vegetation health is used often to estimate crop condition and anticipated yield. If the indices are below 40 indicating different level of vegetation stress, losses of crop and pasture production might be expected; if the indices above 60 (favorable condition) plentiful production might be expected. Vegetation health is very useful for an advanced prediction of crop losses.

Vegetation Health Index data from NOAA's Center for Satellite Applications and Research (STAR) were available in raster format.
