Description

The mosaics are created by using the MODIS 8-Day 500 meter BRDF-Albedo Quality product. Data Quality flags are used to select the best observations from the MODIS 8-day 500 meter Nadir BRDF-Adjusted Reflectance imagery product. This specific mosaic picks observations from the three highest quality categories over a 3-year period of MODIS data.

The MODIS NBAR annual mosaics have been used by government agencies and NGOs in tropical countries as input to generate aboveground biomass/carbon maps. The Woods Hole Research Center has been using the dataset for country capacity building and technical training workshops in tropical countries.
