A Devastating Stall by Hurricane Dorian
When Dorian developed in the Atlantic Ocean during the last week of August 2019, steering winds pushed the storm forward at a respectable rate—about 10-15 miles (16-24 kilometers) per hour. So when the hurricane passed between Puerto Rico and the U.S. Vir

NASA, NOAA Team Up In Effort To Study Impact Of Wild Fires On Air Quality
Historic Greenland Ice Melt Event Follows European Heatwave
The Greenland Ice Sheet experiences surface melting each summer. But in late July 2019, the ice sheet experienced one of the most extensive melt events on record. The event triggered above-freezing temperatures across approximately 60 percent of the ice s
Air Pollutant Forecasts Using the NASA GEOS-CF Model: Global...
The May and June 2019 wildfires that occurred in Alberta, Canada led to increased smog, which resulted in air quality warnings issued in that region. Running at the at the NASA Center for Climate Simulation (NCCS), GEOS-CF was able to simulate in near rea
GMAO Research Brief: Saildrone Baja Field Campaign: A Compar...
Global Modeling and Assimilation Office (GMAO) researchers compared data from a saildrone, an unmanned surface vehicle carrying a comprehensive suite of instruments, to GEOS-FP and MERRA-2 near-surface meteorology and water temperatures datasets produced
Looking For Freshwater In All the Snowy Places
Empowered by the Discover Supercomputer at the NASAA Center for Climate Simulation and the Deepthought2 High-Performance Computing cluster at the University of Maryland, NASA-funded researchers are creating a tool that simulates the best way to detect sno
Impact of Satellite Sea Surface Salinity Observations on ENS...
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 Atmosph...
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
