GEOS-5 simulation of stratospheric ozone intrusion
04.10.14 - NASA Simulation Portrays Ozone Intrusions From Aloft
Ozone high in Earth's atmosphere offers protection from UV rays, but when the gas dips down closer to the ground, it can affect human health.

03.26.14 - AeroCom Compares Organic Aerosol Handling in Global Models
Phase II of the AeroCom project evlauated how 31 different global models handle organic aerosols in the atmosphere, with half now including formation of secondary aerosols from volatile compounds. The NASA Centter for Climate Simulation supported the effort.
Visualization of projected global temperatures in 2099
02.25.14 – Heating Up
Explore climate model projections of 21st century global temperatures in visualizations from NASA's Scientific Visualization Studio and the NASA Center for Climate Simulation.
Image of solar flare observed by IRIS mission
02.21.14 – NASA's IRIS Spots Its Largest Solar Flare
NASA's Interface Region Imaging Spectrograph (IRIS) mission, which utilizes the Pleiades supercomputer to carry out numerical simulations, witnessed an M–class solar flare in late January, the largest flare the spacecraft viewed since its launch June 2013
Visualization of ozone isosurface
02.14.14 - High-Resolution GEOS-5 Simulations of Stratospheric Ozone Intrusions
A 25-km resolution version of the GEOS-5 model has been used with a comprehensive stratosphere-troposphere chemistry module to test the feasibility of detecting the impacts of stratospheric ozone intrusions on surface air quality.
Visualizations of the simulated airframe noise sources for a Gulfstream aircraft
01.30.14 - The Holy Grail of Aircraft Noise Reduction
In the quest for "the holy grail of aircraft noise reduction," NASA's Mehdi Khorrami uses the Pleiades supercomputer to perform simulations of the complex interactions between airflow and airframe components that generate noise on commercial aircraft.
Edge-on projection of gas density for a simulated galaxy
01.22.14 - Galaxy Simulations Take On Ancient Questions
Scientists are using NASA supercomputers to produce state-of-the-art 3D simulations that can follow the formation and evolution of thousands of galaxies simultaneously, to gain deeper insight into the mechanisms of galaxy formation.
Global vegetation density estimates from Landsat satellite data
01.22.14 - NASA Earth Exchange: Meet Up in the NEX World
The NASA Earth Exchange (NEX) is a unique collaborative workspace where Earth scientists can join forces, make new discoveries, and share knowledge to gain a better understanding of our planet.
