Level-II Hawaiian Radars

February 11, 2010

The NWS has begun sending Level-II data for the four WSR-88Ds in Hawaii (PHKM, PHMO, PHWA and PHKI).  

Hawaiian Level-II data

The current Hawaiian Mosaic is constructed from Level-III data. A new mosaic will be created using higher resolution Level-II data. The current Level-III mosaic will become a backup mosaic in case the Level-II data feed goes down. There is currently no time frame as of yet on when the new higher resolution mosaic will be available. The plan is to make this available in the next 2-3 months.

Level-II data will be disseminated  from eight more DOD sights in June. Data will be sent in a recombined format (legacy resolution; 1 degree azimuth, 1000 m radial).

More information can be found here: http://www.weather.gov/os/notification/scn09-51wsr-88d_level2.txt.

Customers Affected

Only customers who use Mosaics or recieve raw data feeds will be affected by this change. Weather Decision Technologies will be working with individual customers for this change, and no action is currently required by customers and clients.

Additional Information

For additional information on this change, contact your account representative immediately or our customer service representatives.

LDM Server Changes
