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.
