AMSR-MODIS Boundary Layer Water Vapor L3 Daily 1 degree x 1 degree V1 (AMDBLWV) at GES DISC

Published by NASA/GSFC/SED/ESD/TISL/GESDISC | National Aeronautics and Space Administration | Metadata Last Checked: October 30, 2025 | Last Modified: 2025-09-10

This data set provides an estimate the marine boundary layer water vapor beneath uniform cloud fields. Microwave radiometry from AMSR-E and AMSR-2 provides the total column water vapor, while the near-infrared imagery from MODIS provides the water vapor above the cloud layers. The difference between the two gives the vapor between the surface and the cloud top, which may be interpreted as the boundary layer water vapor.
