    dct:description "Collection 6.1 MODIS Terra Level 3 atmospheric statistical summaries derived from daily aerosol, cloud, water-vapor and atmospheric-profile products on a global 1-degree equal-angle grid. Aggregation uses calendar-month intervals, including variable month lengths and leap years. Parameter-specific statistics include means, extrema, variability, histograms and confidence/sample summaries. Angular posting is not metre image GSD or underlying instrument resolution. File intervals may include partial observation availability, and global extent does not prove valid retrievals everywhere or on every day. These passive optical/multispectral and infrared observations are not weather forecasts or direct surface pollution measurements. Apply parameter-specific quality, applicability, uncertainty, weighting and sample-count guidance. Native polygons, full aggregation intervals and representative/publication timestamps stay distinct. Only requested metadata pages are indexed; archive registration does not guarantee current freshness." ;
