MODIS (GeoTIFF-Bundle)
Provides MODIS Full Scenes Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) data in TIF format consisting of one file per band with metadata.
Description
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.

Product folder
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.
| File | Description |
|---|---|
<productId>_B{1..11}.TIF | Individual band images |
<productId>_BQA.TIF | Quality assessment band |
<productId>_.TIF.ovr | Overview file for each GeoTIFF file |
