    dct:title "SMAP L4 Global 3-hourly 9 km EASE-Grid Surface and Root Zone Soil Moisture Geophysical Data V008" ;
    dct:description "Surface and root-zone soil moisture estimates from assimilation of SMAP brightness temperatures into a land-surface model, posted every three hours to a 9 km grid. This is an analysis product rather than a direct root-zone measurement or a weather forecast. Grid spacing is distinct from the instrument footprint; quality and uncertainty information apply." ;
