o S4C0: 4km, 30hr, 00Z WRF run, same domain as S4CN, NAM 12km initialization - COMING SOON.
o SP4CN: 4km Southern Plains, same size as the old SPMESO - COMING SOON.
o More 4km forecasts over the same domain as SP4CN - COMING SOON.
o Ensemble products.
o SPSTORM - retired.
o SPMESO - will be retired when SP4CN is 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 8am to 10pm. On these days, forecasts will be cut short.
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

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.
