MODIS/Aqua Total Precipitable Water Vapor 5-Min L2 Swath 1km and 5km

OpenL2Data productAtmosphericMultispectralThermal

Collection 6.1 MODIS Aqua Level 2 total-column precipitable water vapor. Daytime near-infrared retrievals use nominal 1 km sampling over reflective clear land, suitable ocean sunglint and above clouds. The infrared component imported from the atmospheric-profile product uses nominal 5 km sampling during day and night when sufficient fields of view are cloud free. Mixed sampling has no single image GSD, and the conservative night flag does not promise every field at night. Column water vapor is not surface humidity, precipitation or a forecast. Apply product-specific quality, applicability and uncertainty flags. Native granule polygons and observation intervals are preserved; file coverage does not prove valid retrievals everywhere. Only requested metadata pages are indexed, and historical archive registration does not guarantee current freshness.
