RESEARCH HIGHLIGHTS

 

cirrus clouds CMAI (NASA Cloud Modeling and Analysis Initiative) - intended to use satellite observations to extend our understanding of clouds in climate and weather to gobal scale and to evaluate cloud process, weather and climate model representations of cloud processes.
   
Sea-surface height in Gulf Stream region from data-driven simulations at 1/8 degree resolution. ECCO - combining a general circulation model (GCM) with diverse observations in order to produce a quantitative depiction of the time-evolving global ocean state.
   
visualization shows total precipitable water over the United States on July 10, 2004. The data come from an experimental reanalysis of Summer 2004 running the GEOS-5 Data Assimilation System at the 1/2-degree resolution that will be used for MERRAvisualization shows total precipitable water over the United States on July 10, 2004. The data come from an experimental reanalysis of Summer 2004 running the GEOS-5 Data Assimilation System at the 1/2-degree resolution that will be used for MERRA GEOS-5 (GMAO) - the next generation global atmospheric model developed by the Global Modeling and Assimitation Office.

   
A 3D atmospheric chemistry model (GEOS-Chem) evaluating modeled CO2 concentrations and flux estimates GEOS-CHEM - a global 3-D model of atmospheric composition driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office.
   
sensitivity of annually averaged TOA indirect forcing to meteorological field

GMI (Global Modeling Initiative) - a modular chemical-transport model with the ability to incorporate different components and inputs as well as carry out multiyear assessment simulations.

   
Global map showing 1990-1950 Tropospheric column ozone Model E (GISS) - the latest incarnation of the Goddard Institute for Space Studies (GISS) series of coupled atmosphere-ocean models.
