NASACMR Search Granules

Search NASA CMR for individual granules (data files/scenes) within Earth observation collections. Granules are the individual data files (e.g., a single day's MODIS image, one Landsat scene). Search by collection concept ID, bounding box, time range, or keyword. Returns file metadata including download links, spatial coverage, and temporal information. Useful for finding specific satellite data files to download.
