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).
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 NASA Center for Climate Simulation (NCCS).
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.
200 Sandy Bridge Nodes Upgraded to SLES 11/SP3
The NCCS Discover team has upgraded the operating system on more than 200 of the 16-core IBM "Sandy Bridge" nodes to SLES 11/SP3.
Ways to Optimize your Slurm Turnaround
The NCCS is implementing the next phase in the Slurm resource manager deployment. We have prepared some recommendations to optimize job turnaround using Slurm that we encourage Discover users to review and incorporate. Please click on the following link to read more.
