MODIS 2-year Nadir BRDF-Adjusted Reflectance (NBAR) Mosaic

  • This dataset provides MODIS 2-year Nadir BRDF-Adjusted Reflectance (NBAR) mosaics from 2001 to 2017 with annual cadence.

  • The mosaics are created using high-quality observations from the MODIS 8-Day 500 meter BRDF-Albedo Quality product and the 8-day 500 meter Nadir BRDF-Adjusted Reflectance imagery product.

  • The dataset includes 7 bands representing Nadir Reflectance at local solar noon across different wavelengths.

  • MODIS data acquired through the LP DAAC has no restrictions on subsequent use, sale, or redistribution.

  • This dataset has been used for generating 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 2-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.
