[Datastream #BMX-295238]: Is NEXRAD dual-polarization data available on LDM?

Hi Greg,

I moved your email into our inquiry tracking system where more than
two of us can respond.

OK.

re:
> Are fields like ZDR and KDP available via LDM?

I am not positive what these fields are.  I did a Google search for
ZDR, and I found references to differential reflectivity, but it was
ZsubDR which is a parameter used in calibration of differential
reflectivity.

Question:

- what products are your users wanting displays of?

Perhaps the following list of Dual Pol products that are being
sent in NOAAPort and relayed in the IDD NEXRAD3 (aka NNEXRAD)
feed will be helpful to determine what your users want:

FROM:    RICHARD J. VOGT
         DIRECTOR... WSR-88D RADAR OPERATIONS CENTER

SUBJECT: SOLICITING COMMENTS BY MARCH 19 2010 ON PLANS TO
         ADD DUAL POLARIZATION WSR-88D PRODUCTS TO SBN/NOAAPORT
         AND RPCCDS: EFFECTIVE WITH WSR-88D DUAL POLARIZATION
         /NOVEMBER 2010 BETA TEST/

NWS HAS DEVELOPED PROPOSED OPERATIONAL REQUIREMENTS TO DISTRIBUTE
DUAL POLARIZATION WEATHER SURVEILLANCE RADAR-1988... DOPPLER
/WSR-88D/ PRODUCTS VIA SATELLITE BROADCAST NETWORK /SBN/...
NOAAPORT AND RADAR PRODUCT CENTRAL COLLECTION DISSEMINATION
SERVICE /RPCCDS/.

NWS IS REQUESTING COMMENTS THROUGH MARCH 19 2010 ON THE
PROPOSED REQUIREMENTS AND IMPLEMENTATION PLAN. SEND COMMENTS TO:

address@hidden
address@hidden.

IF THE PROPOSED CHANGE IS APPROVED... WE ANTICIPATE IMPLEMENTATION
IN THE NOVEMBER 2010 TIMEFRAME. TABLE 1 CONTAINS THE LIST OF DUAL
POLARIZATION RADAR PRODUCTS PROPOSED TO BE DISTRIBUTED VIA THE
RPCCDS AND SBN/NOAAPORT. THIS DISSEMINATION WILL BEGIN WITH BETA
TESTING OF THE FIRST DUAL POLARIZATION WSR-88D SITE. OTHER BETA
TEST SITES WILL BE ADDED AS THEY ARE MODIFIED. DURING THIS TEST
PERIOD... NWS WILL EVALUATE COMMUNICATIONS LOADING FOR IMPACTS
AND DECIDE WHETHER TO DISSEMINATE DUAL POLARIZATION PRODUCTS
FROM ADDITIONAL SITES MODIFIED DURING FULL SCALE DEPLOYMENT.

As soon as we know which product(s) your users are interested in
seeing, we will be better able to let you know if you should expect
them to be in the NEXRAD3 feed.

Cheers,

Tom
