changes below to improve readability, no substantive changes.
The first Weather Surveillance Radar-1988, Doppler (WSR-88D) Beta
Test start date has moved to January 2011. NWS anticipates the
first dual polarization products and Level II data will be
transmitted from the Beta Test sites approximately 12 days after
the modification begins at each site. Sites will issue a Free
Text Message (FTM) before starting the modification and another
FTM before starting transmission of dual polarization products
and Level II data. The estimated dates for the modification start
and the start of dual polarization data follows, subject to change:
SITE MOD START DATE PRODUCT/DATA
START DATE
Wichita , KS (ICT) Jan 4 Jan 16
Phoenix , AZ (KIWA) Jan 24 Feb 6
Fort Polk , LA (KPOE) Feb 14 Feb 27

The centrally collected WSR-88D products and Level II will be
archived at the National Climatic Data Center (NCDC) and will
be available for download from:
http://hurricane.ncdc.noaa.gov/pls/plhas/has.dsselect
KOUN Level II data is available in real time, subject to down
periods during testing, via the NWS Level II Data Collection,
Distribution, and Archive network.
KOUN products are not being generated and transmitted by a
baseline Radar Product Generator in real time; however, the
National Severe Storms Laboratory is generating displays of
KOUN products, not using baseline software. These displays
are available on an experimental basis at:
http://wdssii.nssl.noaa.gov/web/wdss2/products/radar/koun.shtml
Training materials for NEXRAD agency and external users are
available at:
