Welcome to the
CAPS
ARPS
user web pages.
Temporary changes for the tropical system named "DOLLY":
o Analysis region MESOH1A replaces NEUS.
o Forecast region MESOH1A replaces SPMESO.
o Forecast region SPSTORM won't run.
CAPS is currently experiencing network problems which may affect access to
the web pages.
All runs with the exception of LEAD10 analysis runs prior to January 1st, 2007
have been deleted. Web pages will list all the runs for these days, however,
the data itself is removed. SPC runs prior to the above date aren't
affected.

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 forecasts run are in support of
LEAD
- "Linked Environments for Atmospheric Discovery".
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.
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.
