MODIS/Terra+Aqua BRDF/Albedo QA ValidobsBand6 Daily L3 Global 30ArcSec CMG V061

The MCD43D38 Version 6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) QA ValidObs Band 6 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. MCD43D38 provides MODIS band 6 valid observation quality information for the MCD43D products. MCD43D38 contains the valid observation quality layer representing each of the 16 days of the retrieval period for MODIS band 6. The MODIS BRDF/Albedo products have achieved stage 3 (https://modis-land.gsfc.nasa.gov/MODLAND_val.html) validation. Improvements/Changes from Previous Versions * The Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and corrections to the Terra MODIS forward look-up table (LUT) update for the period 2012 - 2017. * A polarization correction has been applied to the L1B Reflective Solar Bands (RSB).
