MCD43A4.061 MODIS Nadir BRDF-Adjusted Reflectance Daily 500m

    • The MCD43A4 V6.1 product provides 500 meter nadir bidirectional reflectance distribution function adjusted reflectance data for MODIS land bands 1-7.

    • These data are adjusted to model values as if collected from a nadir view using a bidirectional reflectance distribution function.

    • The data are produced daily based on a 16-day retrieval period, with the image date on the 9th day, combining data from Terra and Aqua spacecraft.

    • The dataset is available from 2000-02-24 to 2025-10-05 and has no restrictions on use, sale, or redistribution.

    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.
