MODIS 1-year Nadir BRDF-Adjusted Reflectance (NBAR) Mosaic

  • This dataset provides annual mosaics of MODIS Nadir BRDF-Adjusted Reflectance (NBAR) at 463 meters resolution, derived from the best observations over a 1-year period.

  • It covers the period from February 18, 2000, to January 1, 2017, and includes seven spectral bands.

  • The data has been used for generating aboveground biomass/carbon maps, particularly in tropical regions.

  • It is freely available for research, education, and non-profit use with no restrictions on subsequent use, sale, or redistribution.

  • The dataset is accessible through Google Earth Engine and can be explored using provided code snippets.

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.
