FEATURE STORIES: 2009 ARCHIVE
- 08.24.09 - NASA Expands High-End Computing System for Climate Simulation
- NASA's Goddard Space Flight Center made available to scientists in August the first unit of an expanded high-end computing system that will serve as the centerpiece of a new climate simulation capability.
- 07.28.09 - Simulations Enable Successful Hubble Navigation Experiment
- Months-long simulations at NCCS produced thousands of images that were critical for planning and testing the Hubble Relative Navigation Sensor Experiment.
- 07.20.09 - Super-Eruptions, Climate and Human Survival
- Explosive volcanic eruptions can cool climate for a short period, but can a super-eruption such as occurred 74,000 years ago lead to ice sheet formation?
- 06.09.09 - Transportation Pollution and Global Warming
- Controlling pollution from transportation sources would greatly reduce black carbon and ozone emissions, which affect both climate and also human health.
The study included global climate model simulations run at NCCS.
- 05.25.09 - Particles Multi-Task to Change Climate
- Tiny particulate matter in the atmosphere can both warm and cool the climate. Global climate model experiments run on the NCCS Discover supercomputer seek to answer: Which effect is dominant, and will the balance change as the atmosphere warms due to greenhouse gases?
- 05.20.09 - HEC Wide-Area Networking Transitioning to NISN May 27, 2009
- NASA-internal wide-area networking services for the High-End Computing (HEC) Program are transitioning to the NASA Integrated Services Network (NISN). HEC's new NISN services include a direct 10 gigabit-per-second network pathway between its two facilities.
- 05.18.09 - The Ozone Hole and Global Warming
- A new study led by the Goddard Institute for Space Studies examines possible connections between reduced Southern Hemisphere ozone and Northern Hemisphere Arctic warming.
- 05.18.09 - NASA Supercomputing Goes Green: Modeling Ocean Climate
- Earth scientists are reaping huge benefits from research performed on NASA's advanced supercomputers.
- 04.13.09 - Experiment May Help Forecast Deadly Cyclones
- NASA satellite data and a new modeling approach could improve weather forecasting and save more lives when future cyclones develop.
- 04.09.09 - Climate Change and Atmospheric Circulation Will Make for Uneven Ozone Recovery
- New atmospheric modeling studies by NASA suggest the ozone layer of the future is unlikely to look much like the past because greenhouse gases are changing the dynamics of the atmosphere.
- 04.08.09 - Aerosols May Drive a Significant Portion of Arctic Warming
- New NASA research using a coupled ocean-atmosphere model suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles.
- 03.18.09 - Simulation Shows World Without Ozone Layer
- The Montreal Protocol has helped reduce contaminants responsible for damage to the ozone layer ... but what if the landmark treaty had never existed?
- 01.22.09 - Solar Variations and Climate
- Modeling studies run at the National Center for Computational Sciences (NCCS) show that changes in solar irradiance that occur during the solar cycle have an influence on rainfall patterns, much like weighting the dice.
