    dct:description "Collection 6.1 MODIS daily statistical summaries from Aqua, combining aerosol, cloud, water vapor and atmospheric-profile retrievals on a global 1 degree equal-angle grid over a 24-hour UTC interval. Statistics, histograms, confidence and sample counts vary by parameter. Angular grid posting is not instrument resolution or continuous valid observation coverage. These passive optical/multispectral and infrared observations are not weather forecasts or direct surface pollution measurements. Apply parameter-specific quality, applicability, uncertainty and sampling guidance. Native granule/grid geometry and observation intervals stay preserved; only requested metadata is indexed and archive availability does not guarantee freshness." ;
