Atmospheric Dust Rivers: Saharan Dust Makes the Journey to t...
During June 2020, dust from the Sahara Desert was forecast and observed to cross the Atlantic Ocean, impacting the Caribbean and the U.S. Gulf Coast states, and recirculated over parts of the mid-Atlantic region.
GEOS Captures Tropical Cyclone-Like System "Trudy"...
NASA's current GEOS FP forecasting system, which runs at the NASA Center for Climate Simulation (NCCS), showed all the ingredients necessary to trigger Trudy — possibly the first Mediterranean "Medicane" correctly forecast and analyzed by GEOS.
Developing an Ozone Climate Data Record from Assimilation of...
Assimilation of high-resolution satellite observations can provide accurate representations of stratospheric ozone on time scales ranging from hours to decades, as shown by a Global Modeling and Assimilation Office study run at the NASA Center for Climate
How NASA is Helping the World Breathe More Easily
NASA has been involved in the study of air quality for decades from space and with ground sensors. Merging satellite data with models provides a snapshot of chemistry throughout the atmosphere at any given time and helps predict air quality worldwide.
NASA Study Adds a Pinch of Salt to El Niño Models
When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity — or saltiness — data significantly improves model accuracy, according to a new NASA study carried out at the NASA Center for Climate Simulati
Earth Day Countdown T-17: Chemistry in the Atmosphere
Using the NASA Center for Climate Simulation (NCCS) Discover supercomputer, researchers can visualize the extremely complex chemistry that takes place in the atmosphere to form one common air pollutant — surface ozone.
New 3D View of Methane Tracks Sources and Movement around th...
The computations for NASA’s new 3-dimensional portrait of methane concentrations were run at the NASA Center for Climate Simulation (NCCS).
Climate Modeling Then and Now
Computer models of climate have changed dramatically since the first Earth Day.
How Earth Climate Models Help Scientists Picture Life on Uni...
NASA’s Discover supercomputer is tasked with running sophisticated climate models to predict Earth’s future climate but is also sussing out something much farther away: whether any of the more than 4,000 curiously weird planets beyond our solar system dis
Global Transport of Smoke from Australian Bushfires
The transport of the Australian bushfire smoke plumes around the globe has accelerated through deep vertical transport into the upper troposphere and even the lowermost stratosphere, as shown by the GEOS global data assimilation and forecast system runnin
