NASA Model Reveals How Much COVID-related Pollution Levels D...
Using computer models to generate a COVID-free 2020 for comparison, NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide concentrations by nearly 20%
NASA Supercomputing Study Breaks Ground for Tree Mapping, Ca...
Scientists from NASA’s Goddard Space Flight Center and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests, discovering billions of trees in arid and semi-arid regions and laying the
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.
