Cross-section from visuaization of MERRA-2 ozone trend 1998–2016
05.29.18 – Recent Decline in Lower Stratospheric Ozone Attributed to Circulation Changes
Studies with the MERRA-2 reanalysis show that transport changes between 1998 and 2016 most likely caused ozone in the extratropical lower stratosphere to decline. MERRA-2 runs at the NASA Center for Climate Simulation (NCCS).

05.02.18 - Creating a Computing Center That Can Solve Science’s Most Complex Problems
Fueled by over 2 megawatts of power and cutting-edge equipment from the NASA Center for Climate Simulation (NCCS), the Virginia Tech Biocomplexity Institute's new data center is ready to help collaborators address issues ranging from disasters to disease outbreaks.
Visualization of proton energy flux to the surface of the Moon
04.26.18 – Lunar Swirl Features Reproduced by Modeling Solar Wind Standoff
Researchers at the Institute for Modeling Plasma, Atmospheres and Cosmic Dust (IMPACT) at the University of Colorado Boulder, used NASA's Pleiades supercomputer to develop the first 3D simulations to disentangle the movement of ions and electrons as the solar wind interacts with lunar magnetic anomalies.
Visualization of stratospheric intrusion
04.26.18 - Stratospheric Intrusion-Influenced Ozone Air Quality Exceedances Investigated in the NASA MERRA-2 Reanalysis
NASA's MERRA-2 Reanalysis is an ideal candidate for the scientific studies of stratospheric intrusions since it is such a high-resolution global dataset and also assimilates both ozone and meteorological observations. MERRA-2 runs at the NASA Center for Climate Simulation (NCCS).
3D visualization of sea surface temperature and ocean currents during El Niño
04.16.18 – Tracking El Niño
NASA Goddard's Global Modeling and Assimilation Office (GMAO) combined satellite observations with model data to recreate the 2015-2016 El Niño in 3D. The GMAO computed the synthesis at the NASA Center for Climate Simulation (NCCS).

04.11.18 – Transiting Exoplanet Survey Satellite (TESS) Science Data Pipeline
NASA’s ongoing search for life in the universe produces a lot of data. The agency’s new planet-hunting mission, the Transiting Exoplanet Survey Satellite, or TESS, will collect 27 gigabytes per day—and the Pleiades supercomputer will process TESS’s biweekly data deluge of almost 10 billion pixels in three to five days.

03.14.18 – How Much Snow Accumulates in North America Each Year? More Than Scientists Thought
Scientists at The Ohio State University have revised an estimate of snow volume for the entire continent, and discovered that snow accumulation in a typical year is 50% higher than previously thought. So far, they have used 1.8 million core-hours on NASA's Pleiades supercomputer and produced about 16 terabytes of data to run their regional climate computer models.

03.05.18 – Helping Keep Astronauts Safe with Advanced Simulations, Visualizations
Cutting-edge simulations run on NASA's Pleiades supercomputer help engineers shape the final configuration of the Orion launch abort vehicle, designed to keep astronauts safe during launch.
02.22.18 - Active Winter Weather Forecasted Over North America Following a Major Stratospheric Sudden Warming Event
In its routine 10-day forecasts, the global Goddard Earth Observing System forward processing (GEOS-FP) system successfully tracked the development of the first major mid-winter stratospheric sudden warming (SSW) event in 5 years. GEOS-FP runs 4 times per day at the NASA Center for Climate Simulation (NCCS).

01.11.18 – No Planets Needed: NASA Study Shows Disk Patterns Can Self-Generate
A new NASA study shows rings, arcs and spirals in disks around stars may not be caused by planets. They may self-generate, per simulations run on the Discover supercomputing cluster at the NASA Center for Climate Simulation (NCCS).
Visualization of the Milky Way galaxy center
01.11.18 – Galactic Center: Scientists Take Viewers to the Center of the Milky Way
Astrophysicists have created an immersive 360-degree visualization of the center of the Milky Way galaxy using data from NASA's Chandra X-ray Observatory. Hydrodynamic simulations and visualization computations were run on the NASA Advanced Supercomputing (NAS) facility's Pleiades supercomputer.
