Unidata IDD users:
Content of the FSL2, NNEXRAD, UNIWISC, and NIMAGE datastreams is
changing.
FSL2
In response to a site request to the Unidata Users Committee, NOAA/FSL
begain adding hourly-summary and 6-minute RASS data to the IDD FSL2
datastream in late August. Information on the RASS can be found in the
following NOAA/Forecast Systems Laboratory webpages:
NOAA Profiler Network
http://www.profiler.noaa.gov/npn/aboutNpnProfilers.jsp
Listen to a 404 MHz RASS Audio Signal
http://www.profiler.noaa.gov/npn/sounds/rassSound.au
The RASS data is being broadcast in a netCDF that is similar to the
wind profiler data that has been available in the FSL2 datastream for
over a decade.
Support for the RASS data will be added to the existing ldm-mcidas
(proftomd) and GEMPAK (dcncprof) decoders in the October timeframe.
FNEXRAD and UNIWISC
On Sunday, October 1 the NEXRAD Level III and GOES floater products
will be removed from the FNEXRAD and UNIWISC IDD feeds, respectively.
The removal of the floaters is based on guidance provided by
the Unidata Users Committee. The decision to terminate the floaters
was informed by the lack of community participation in floater
location, and by the small number of comments (3) to a survey asking
the community for input in winter, 2004.
We would like to remind users of these products that they have more
flexible methods for getting the same data:
GOES floaters
- users of ADDE-enabled applications (McIDAS and the IDV) can create
floaters tailored to their own needs especially from the GOESEAST,
EAST, WEST, GINIEAST, and GINIWEST datasets that are made available on
several of the Publically Accessible McIDAS ADDE servers listed in
http://www.unidata.ucar.edu/software/mcidas/adde_servers.html
FNEXRAD floaters
- users can request whatever set of NEXRAD stations and products they
wish from the IDD NNEXRAD datastream
We would like to extend our heartfelt thanks to the folks at
Millersville University of Pennsylvania -- especially Eric Horst --
who have been faithfully managing both the NEXRAD and GOES floater
selection for many years!!
NIMAGE
The following notification regarding sounder image products contained
in the NOAAPORT broadcast and distributed in the IDD NIMAGE feed was
received today:
FROM: PAUL HIRSCHBERG
CHIEF...SCIENCE PLANS BRANCH
OFFICE OF SCIENCE AND TECHNOLOGY /OST/
SUBJECT: IMPROVED RESOLUTION OF GOES SATELLITE SOUNDER DERIVED
PRODUCT IMAGERY /DPI/...EFFECTIVE NOVEMBER 1 2005
EFFECTIVE NOVEMBER 1 2005: THE NATIONAL ENVIONMENTAL SATELLITE...
DATA... AND INFORMATION SERVICE /NESDIS/ IS IMPROVING THE
RESOLUTION OF ITS GOES SATELLITE SOUNDER DERIVED PRODUCT IMAGERY
/DPI/. THE CURRENT PRODUCTS USE A 5 BY 5 PIXEL /APPROXIMATELY
50KM BY 50 KM/ AVERAGE FOR PRODUCT GENERATION. THE IMPROVED
RESOLUTION WILL BE GENERATED USING 1 BY 1 PIXELS /APPROXIMATELY
10 KM BY 10KM/. THE ENHANCEMENT WILL TAKE PLACE WITHIN THE
PRODUCT GENERATION AT NESDIS. THIS WILL NOT IMPACT THE FILE SIZE
NESDIS SENDS TO CUSTOMERS FOR EACH OF THE SOUNDER DPI. IT WILL
IMPROVE PRODUCT PRESENTATION. THESE DPI PRODUCTS COME UNDER THE
BULLETIN HEADERS TIGN16 KNES... TIGN17 KNES... TIGN18 KNES... AND
TIGN27 KNES.
FOR NWS AWIPS CUSTOMERS: OPTIONAL ENHANCEMENT CURVES /COLOR
TABLES/ FOR THESE PRODUCTS DEVELOPED BY THE COOPERATIVE INSTITUTE
FOR METEOROLOGICAL SATELLITE STUDIES /CIMSS/ ARE SCHEDULED TO BE
DELIVERED AS PART OF AWIPS RELEASE BUILD OB6. UNTIL OB6 IS
DEPLOYED... THESE ENHANCEMENT CURVES COULD BE RECREATED LOCALLY
WITH INFORMATION FOUND AT:
HTTP://CIMSS.SSEC.WISC.EDU/GOES/VISIT/SOUNDER_ENHANCEMENTS.HTML
IF YOU HAVE QUESTIONS CONCERNING THESE PRODUCTS...PLEASE CONTACT:
