High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).


A simulated view from NASA's Interface Region Imaging Spectrograph (IRIS) spacecraft
1.27.16 - A Stellar Collaboration: Supercomputing and NASA's IRIS Observatory
Bringing together observations made by NASA's IRIS spacecraft with simulations run on NASA's Pleiades supercomputer, scientists are studying the Sun's atmosphere more closely than ever before.

01.22.16 - NASA's GEOS-5 Provides a Satellite View of Historic Winter Storm
The NASA GEOS-5 atmospheric data assimilation system follows an historic winter storm as it approaches the mid-Atlantic January 22–24, where it is expected to produce a wide swath of more than 2 feet of snow. GEOS-5 runs at the NASA Center for Climate Simulation (NCCS).
Visualization of column-integrated atmospheric carbon dioxide concentrations for May 1, 2013
12.31.15 - GEOS-5 Science Snapshots
NASA's Global Modeling and Assimilation Office has made advances with its Goddard Earth Observing System Model Version 5 (GEOS-5) as varied as a 1.5-km global weather simulation and a decades-long reanalysis of observations, all using the NCCS.
Visualization of monthly mean difference between skin SST and bulk SST for Apr 2012
12.21.15 – Skin Sea-Surface Temperature Assimilation in GEOS-5 ADAS
Satellite and in-situ observations of Sea-Surface Temperature (SST) show high variability, including a diurnal cycle and very thin, cool skin layer in contact with the atmosphere. The GEOS-5 Atmospheric Data Assimilation (ADAS) has been modified to incorporate these effects and also to assimilate Advanced Very High Resolution Radiometer (AVHRR) brightness temperatures to obtain realistic estimates of skin SST.

12.18.15 – NASA Study: Examination of Earth’s Recent History Key to Predicting Global Temperatures
Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change, according to a new NASA study published Dec. 14 in the journal Nature Climate Change. The research leveraged the Discover supercomputer at the NCCS.
