The MODIS Combined Aqua and Terra Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) suite of products are now being generated at the MODIS NRT processing system and are made available to the public through NASA's EOSDIS LANCE.
The NRT BRDF/Albedo processing uses the same science algorithm as the operational processing at MODAPS generating the product daily using all good quality observations of corrected reflectance acquired by the MODIS on-board Terra and Aqua. The daily product weights the data as a function of quality, observation coverage, and temporal distance from the day of interest. However, while the operational processing retrieves the product for the 9th day of the 16-day period, the NRT processing retrieves the product for the leading day of the 16-day period. The data day is identified in the local granule ID of the product. For the same data day, retrievals from the NRT have been verified to be of near science quality as operational product with at least 80% of retrievals to be within 1% of operational product at pixel level. The BRDF/Albedo suite of products include
