Impact of Satellite Sea Surface Salinity Observations on ENSO Predicti...
According to research run at the NASA Center for Climate Simulation (NCCS), assimilating satellite sea surface salinity from NASA’s Aquarius and SMAP satellite instruments improves the analyses of the near-surface density and the mixed layer depth.
Choking on Saharan Dust
A new analysis supported by the NASA Center for Climate Simulation (NCCS) suggests that exposure to mineral dust may be a bigger cause of premature death in Africa than previously thought.
Assimilation of Satellite Soil Moisture for Improved Atmospheric Reana...
Based on experiments spanning the summer of 2013, NASA's Global Modeling and Assimilation Office finds that the use of soil moisture observations in the reanalysis resulted in regional improvements in near-surface atmospheric conditions. The experiments r
A Scale-Aware Representation of Convection in the GEOS Model
Recently updated parameterizations estimating convection and shallow cumulus clouds, along with evolving development of the finite-volume cubed-sphere (FV3) dynamical core, have led to a unique scale-aware capability for the GEOS model. Implementation in
Using Loon Stratospheric Balloon Observations in Global Assimilation
Assimilating three months of wind measurements from experimental super-pressure balloons into the NASA GEOS global data assimilation system (DAS) significantly improves analyses of tropical winds. The DAS runs at the NASA Center for Climate Simulation (NC
Greenhouse Gas ‘Detergent’ Recycles Itself in Atmosphere: NASA Study
A simple molecule in the atmosphere that acts as a "detergent" to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research including
Pathways Intern: Jordan, Computer Science

July 2018 Mid-Atlantic Atmospheric River and Extreme Precipitation Eve...
The Modern Era Retrospective analysis for Research and Applications, version 2 (MERRA-2), which runs at the NASA Center for Climate Simulation (NCCS), clearly captured this event in which an entire months’ worth of precipitation fell in a matter of days.
Pulsar in a Box’ Reveals Surprising Picture of a Neutron Star’s Surrou...
A simulation run on NASA's Discover and Pleiades supercomputers yields a more detailed understanding of the complex, high-energy environment around spinning neutron stars called pulsars.
The Complex Evolution of Florence’s Winds
The GEOS weather model running at the NASA Center for Climate Simulation (NCCS) captured the storm’s wind field between September 1 and September 14, 2018.
