Wildland Fire Assessment System (WFAS) AVARR NDVI Greenness Reference is the comprehensive source of images, data archives, and methods for handling.
These images, derived from a satellite sensor, have been produced weekly since 1989, producing a historical record of vegetation phenology that can be used to characterize current vegetation “greenness”. They can be used to cross-reference with drought assessments and other characterizations of plant development, moisture stress and curing. Cloud cover can have a significant impact on image quality in portions of the image.
While not an estimate of live fuel moisture, spatial distribution of NDVI estimates and its climatological derivatives can provide important insight to past and current vegetative state as well as overall landscape flammability during the growing season.
There are several depictions that allow you to evaluate the current NDVI status:
