The MODIS BRDF/Albedo products currently provide robust measures of the albedo and characteristic anisotropy of the global land surface. The algorithm depends on high-quality, multi-day, cloud-free, atmospherically-corrected surface reflectances and a linear kernel-driven model of the surface anisotropy. Products have been tailored to meet the needs of the global and regional modeling communities as well as those of users of direct broadcast and field instrumentation data. The newest reprocessing of the operational products (version 005) is now underway and represents several major enhancements including increased spatial resolution (500m), improved temporal resolution (every 8 days based on the last 16 days of directional observations) and simplified quality fields. The direct broadcast algorithm further enhances the operational products by providing a daily rolling product that is tailored to a specific region. Validation of both the daily and periodic values has begun and early results will be presented.
