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:

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:
