Page Summary
-
The WHBU/NBAR_1YEAR dataset provides annual mosaics of Nadir BRDF-Adjusted Reflectance (NBAR) derived from MODIS data, available from 2000 to 2017.
-
These mosaics are created by selecting the best quality observations from the MODIS 8-day products over a 1-year period.
-
The dataset has been used by government agencies and NGOs for generating aboveground biomass/carbon maps in tropical countries.
-
The data includes seven bands representing Nadir Reflectance at local solar noon for different wavelengths, with a pixel size of 463 meters.
-
MODIS data and products acquired through the LP DAAC have no restrictions on subsequent use, sale, or redistribution.

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 1-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.
