Page Summary
-
This dataset provides MODIS 3-year Nadir BRDF-Adjusted Reflectance (NBAR) mosaics from 2002 to 2017 with a 463-meter pixel size.
-
The mosaics are created using the MODIS 8-Day 500 meter BRDF-Albedo Quality product, selecting the best observations over a 3-year period.
-
The dataset includes seven Nadir Reflectance bands at local solar noon with different wavelength ranges.
-
MODIS data acquired through the LP DAAC has no restrictions on subsequent use, sale, or redistribution.
-
This dataset has been used to generate aboveground biomass/carbon maps and for capacity building in tropical countries.

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.
