Tampa NWS starts there upgrade February 27th. http://www.srh.noaa.gov/images/tbw/TopNews/PDF/ChangeinDualPolInstall.pdf
But according to the NWS the Dual-Pol Radar will not be available to the public untill 2013 after all of the NWS offices have been upgraded.
Quote: Following the upgrade, Dual Polarization products will be available for usage one week after the install is
complete. Please note, however, that dual pol products will not be available on public NWS radar web
pages until all U.S. radar sites have been upgraded in 2013.
It's still viewable through GRL2 products.
I spoke with Steve Nelson who's the COO of the Atlanta NWS office about their DP upgrade that happened at the end of November. He was very excited about it and talked about how it's already pinpointed hail core's and debris ball's in some of the severe weather we've had.
