Spectral BRDF climatology from merge of snow and nosnow products upscaled at 0.05º derived from 17 records (one for each year form 2000..2016) for each land surface pixel for each day of year. each pixel has an estimated uncertainty based on a weighting of the MODIS MCD43A2 Quality bit flags. This dataset represents a global climatology in the 7 MODIS spectral bands and is used within the QA4ECV for regularisation purposes as the "prior" for spectral inversions.
