CCSM3 HOMME - TMQ (Water Vapor) / Landscan

The proper simulation of the distribution of water vapor in the climate system is essential to the accurate treatment of the hydrological cycle and the planetary radiation budget. These images show the simulated monthly-averaged distribution of the total column water vapor from a high-resolution configuration of the CCSM Community Atmospheric Model.

The LandScan Dataset comprises a worldwide population database compiled on a 30" X 30" latitude/longitude grid. LandScan has been developed as part of the Oak Ridge National Laboratory (ORNL) Global Population Project for estimating ambient populations at risk.

Resolutions: 1260x1080 (29 MB), 750x640 (22 MB)
Length: 60 seconds
Notes: HOMME: 1/8 degree resolution; Two-hourly; Two months (Dec. and Jan.). Original cubed-sphere gridded data was interpolated to a grid 25% higher resolution than the original run to avoid interpolation artifacts. CAM 3.5.1 'track 1' physics configuration, but with no surface roughness term in the gravity wave drag parametrization. The data is comprised of instantaneous fields. The LandScan data resolution is 30 arc seconds. The coordinates are Geographic WGS84. The LandScan dataset shown in the visualization is LandScan 2005.
