    dct:description "Publisher-reviewed estimated methane plume complexes, with 60 m raster data and GeoJSON outline and uncertainty assets. Emission rates may be unavailable. The viewer retains STAC artifact geometry; locations within linked GeoJSON assets are not automatically ingested. Publisher quality, acquisition gaps and download authentication requirements apply. Native archive extent is nominal scope rather than complete valid coverage. This is not a terrain grid." ;
