Atmospheric and Oceanic Diagnostics
Major Projects
Much of the Group's activities involve assessments of large-scale atmospheric and oceanic models and data sets. The chief measures used for these studies are global and regional values of angular momentum, energy and water vapor, and transfers of these quantities within and between elements of the coupled climate system.
Major efforts of the Group include:
- Atmospheric reanalysis assessment of the multidecade set from the National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR).
- Atmospheric Model Intercomparison Project (World Climate Research Programme): validations of an ensemble of climate model results.
- NASA Earth Observing System: studies of Earth System Dynamics (teamed with University of Texas at Austin's Center for Space Research.
- NASA Goddard Laboratory for Atmospheres: assessments of physical parameterizations of general circulation models and of the utility of the Goddard Earth Observing System Data Assimilation System (GEOS-1 DAS) analysis.
- International Earth Rotation Service: participation in its Special Bureaus for the Atmosphere and Ocean.
- Analysis of ocean general circulation models.
- Studies of sea level from altimetry (TOPEX/Poseidon, Jason-1).
- Predictability of ocean flows.
- Ocean structure near the continental shelf and its biogeochemistry.
- Snow cover and climate variations.
- Momentum Data Services.
