Combined MODIS local solar noon data from the MCD43D32 product across the globe, August 10, 2020.View full-size image
The MCD43D32 Version 6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) QA Local Solar Noon 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. MCD43D32 provides local solar noon 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.
The MCD43D32 layer contains the local solar zenith angle at the local solar noon of the representative 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.
