Combined MODIS BRDF Albedo uncertainty data from the MCD43D41 product across the globe, August 10, 2020.
View full-size imageThe MCD43D41 Version 6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) QA Uncertainty dataset is produced daily using 16 days of Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) data at 30 arc second (1,000 meter (m)) resolution. Data are temporally weighted to the ninth day which is reflected in the Julian date in the file name. This Climate Modeling Grid (CMG) product covers the entire globe for use in climate simulation models. Due to the large file size, each MCD43D product contains just one data layer. MCD43D41 provides BRDF inversion information for the MCD43D products.
Users are urged to use the band specific quality flags to isolate the highest quality full inversion results for their own science applications as described in the User Guide.
MCD43D41 layer contains the uncertainty range of each BRDF/Albedo pixel for the retrieval period.
Validation at stage 3 has been achieved for all MODIS BRDF/Albedo products. Further details regarding MODIS land product validation for the MCD43 data products are available from the MODIS Land Team Validation site.
