A data block that provides MODIS MCD43A4 full scenes. These images are acquired by the Terra and Aqua satellite sensors at a daily revisit rate anywhere on the globe. The datasets are available starting with 2000.
See this block on the marketplace.
The geographic coverage is global.

The data products are corrected using the bidirectional reflectance distribution function to model the values as if they were collected from a nadir view, which ensures a stable and consistent product.

The output dataset is stored in a product folder with the same name as the product ID. This folder contains 14 GeoTIFF images and 3 metadata files.
