MODIS NDVI is calculated in the same way as before, namely the ratio between reflectance in the near infrared (NIR) and visible (VIS) regions:
NDVI = (NIR-VIS)/(NIR+VIS)
Healthy vegetation strongly reflects NIR radiation, and absorbs VIS for driving photosynthesis. Click for wet season MODIS images of natural colors, brightness, greenness and wetness.
