    dct:title "SWOT Level 2 Water Mask Pixel Cloud Data Product, Version D" ;
    dct:description "SWOT Version D unstructured geolocated KaRIn water-pixel detections, including WGS84 ellipsoidal heights, radar backscatter and surface classification flags. Pixel sampling is irregular and differs across and along track, so a single image GSD is unspecified. Pixel heights are not the same as geophysically corrected raster heights; apply the product-specific corrections and quality screening. These active microwave radar observations are not weather or flood forecasts, a terrain DEM, or proof of inundation everywhere inside a file footprint. Native granule geometry and acquisition intervals are preserved; individual water pixels reside in remote publisher assets. Archive scope and publication cadence do not guarantee freshness or continuous coverage." ;
