Welcome to the
CAPS
ARPS
user web pages.
There will be upcoming changes over the next few months for the various spring
experiments.
WARNING - "big animation" on the forecast CONUS20 regions (85 images) or the
SPV4CN/SPV4C0 regions (55 images) will use a lot of memory, as they are
1500x1500 images. They could cause some systems to get very slow or possibly
lock up.

Watch for extra run with names that start with "mesoh" during hurricane season.
CAPS is located in the
National Weather Center.
Daily
ARPS and
WRF
forecasts are run on the
OSCER supercomputers.
Some of the jobs run are in support of
LEAD
- "Linked Environments for Atmospheric Discovery".
OU Supercomputers have routine maintenance scheduled on Wednesdays
from 6am to midnight. On these days, forecasts will be cut short.
Maintenance will only be as necessary during the spring experiments.
LEAD10 analyses are moved to a LEAD computer system
during the weekly maintenance slot.
Only emergency maintenance days will occur during the spring experiments.
Bookmarking favorite images, animation loops, and multipanels is possible,
though the URL's aren't obviously from the web pages. Please send email

r_e_a_l_t_i_m_e_@_c_a_p_s_._o_u._e_d_u
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.
Hourly Analysis Regions:
CONUS20 - CONtinental U.S., 20km grid (CONUS 27km replacement).
LEAD10 - LEAD 10km analysis over the U.S., every hour.
NEUS - NorthEastern U.S. (analysis only), 9km grid.
SPMESO - Southern Plains MESOscale, 9km grid.
CONUS20 and SPMESO are ready about 30 minutes past the hour,
while the the NEUS
is ready about 60 minutes past the hour.
LEAD10 is now ready about 20 minutes past the run hour or earlier except on
supercomputer maintenance days. Run times will be quicker once the analysis
runs are moved to the new ingest system, with necesary times benchmarked.
Daily Forecastion Regions:
CONUS20 - CONtinental U.S., 00Z run, 00Z NAM boundary data, 84 hours,
20km grid, ARPS and WRF
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 (remove underscores) to
