Tool to retrieve collections from the Common Metadata Repository (CMR). Use when you need to search NASA science data collections by spatial, temporal, or metadata filters. Call after confirming search criteria.
circlestringCircle for spatial queries in 'lat,lon,radius' format (radius in km). Example: '34.5,-117.4,50'. Mutually exclusive with 'bounding_box' and 'polygon'.
keywordstringFree-text keyword search against metadata.
polygonstringPolygon for spatial queries as whitespace-separated 'lat1,lon1 lat2,lon2 ...'. Mutually exclusive with 'bounding_box' and 'circle'.
versionstringVersion of the collection, e.g., '6'.

page_sizeintegerResults per page (1-2000). Default=10.
concept_idstringExact CMR collection concept ID, e.g., 'C1234567890-LPDAAC_ECS'. Use to retrieve a single known collection.
instrumentstringInstrument used to acquire data, e.g., 'MODIS'.
short_namestringShort name of the collection, e.g., 'MODIS_Terra'.
