On Tuesday, 16 July 2013, the National Centers for Environmental
Prediction (NCEP) is scheduled to transition operations from the current
generation of supercomputers in Gaithersburg and Fairmont (Central
Computing System (CCS)) to the new generation of supercomputers in
Reston and Orlando (Weather and Climate Operational Supercomputing
System (WCOSS)), pending successful completion of the final code
transition and evaluation that is currently underway. As of that date,
all operational model guidance will be generated from one of those two
supercomputers.
In preparation for the WCOSS transition, NCO will be conducting two live
tests on WCOSS during which we will disseminate the products from WCOSS
as the official operational products. That is, we will shut off
dissemination from the CCS, and send products out from WCOSS only. The
tests are scheduled to occur on Tuesday June 25th and Tuesday July 2nd.
The tests will begin with the 06Z GDAS run and go through the 15Z SREF.
Known differences between the model suite on the CCS and on WCOSS are
outlined at the following webpage:
http://www.nco.ncep.noaa.gov/pmb/changes/docs/wcosseval.shtml which is
being updated frequently. We encourage users to prepare for these live
tests.
*Please note:* If Critical Weather Day (CWD) is declared or in effect
for either scheduled test day, the live test will be postponed.
