Description

The MCD43A4 V6.1 Nadir Bidirectional Reflectance Distribution Function Adjusted Reflectance (NBAR) product provides 500 meter reflectance data of the MODIS "land" bands 1-7. These are adjusted using a bidirectional reflectance distribution function to model the values as if they were collected from a nadir view. The data are produced daily based on a 16-day retrieval period, with the image's date occurring on the 9th day. This product combines data from both the Terra and Aqua spacecrafts, choosing the best representative pixel from the 16-day period.
