Welcome to the
CAPS
ARPS
user web pages.
Due to the upcoming Spring Experiments, most of the routine services disabled.
They will resume in June. At the current time, the only routine job is the
hourly LEAD10 analysis runs.
For the 2008 Spring Experiments, several runs are using ARPS3DVAR as the
analysis package instead of ADAS. SPC in 2007 didn't use an analysis package.
CASA in 2007 used ADAS. SPC runs CN and C0 and CASA forecast runs have
high temporal data images. Use "A" (animation) to view them.
SPC Runs...
Runs Sunday night thru Thursday night.
Run length is 30 hours.
WRF model used.
All runs are 4km resolution except SPC2, which is 2km.
The domain is larger than previous years.
CN - Control Run, full analysis.
C0 - Same as CN, except no ARPS3DVAR
N1, N2, N3, N4, P1, P2, P3, P4 - Ensemble members. All use NCEP SREF data plus
ARPS3DVAR output from CN run.
SPC2 - 2km with ARPS3DVAR.
SPC Web Pages are here.
CASA Runs:
Analysis runs...400m grid. New runs every 5 minutes.
Forecast runs...1km grid. New runs when weather in domain.
CASAONLY - 5 minute runs over CASA domain with CASA radar data only.
CASA400 - 5 minute runs with all available data.
CASA - Forecast runs when weather is interesting.
CASAT - Same as CASA, however, only NEXRAD data is used.
CASA Web Pages are here.

CAPS is now located in the
National Weather Center.
Daily
ARPS and
WRF
forecasts are run on the
OSCER supercomputers.
Some of the forecasts run are in support of
LEAD
- "Linked Environments for Atmospheric Discovery".
SPC forecasts are run using the
Pittsburgh Super Computer site.
OU Supercomputers have routine maintenance scheduled on Wednesdays
from 8am to 8pm. On these days, forecasts will be cut short, though they
may eventually run. LEAD10 analyses are moved to a LEAD computer system
during the weekly maintenance slot. Maintenance days will be less frequent
during the spring experiments, and may be moved to other days.
Bookmarking favorite images, animation loops, and multipanels is possible,
though the URL's aren't obviously from the web pages. Please send email to
realtime@caps.ou.edu
for more information.
Analysis and forecasts history files are available for
ftp
in both HDF4 and netCDF format.
HDF4 may be discontinued in the future, however, there are no immediate plans.
The data is at
ftp://caps.ou.edu/pub/arpsdata.
Both HDF4 and netCDF format are supported.
OSCER
Supercomputers are a big part of the CAPS forecasts. Thanks go to the
System Admins who work to keep the systems running!
We would like your feedback. Send email to
realtime@caps.ou.edu.
If there is a problem, we would like to know.
Thanks for visiting the CAPS ARPS user web pages.
