Subject:  Las Vegas Radiosonde Replacement System (RRS)
          Operational Date and Communications Identifier Changes
          For Upper-Air (UA) Products from WFO Las Vegas
          Effective December 18 2010

The NWS Weather Forecast Office (WFO) in Las Vegas, NV, (VEF)
will initiate daily RRS UA observations on Dec. 18, 2010 and
reach twice per day observations on Jan. 16, 2011. This change
follows the termination at Desert Rock (DRA) of Radiotheodolite
Tracking (ART) and Radio Direction Finding (RDF) radiosonde
observations.

Please update your metadata files for these initial coordinates
immediately so your UA derived products will not give erroneous
information on Dec. 18, 2010.

Table 1. Initial Coordinates of Las Vegas Release Point Location

NAME       INDEX     LAT            LON             ELEVATION
LAS VEGAS  72388     36.047139N     115.184639W     693.4 M

NOTE:  The WMO Index Number Will Be 72388.

All users are advised to update their communications identifiers
immediately in order to receive upper-air coded text products
from Las Vegas.

Institutional and commercial distributors who generate derived
products must ensure their communication system directories
exactly match the new headings by Dec. 18, 2010. Failure to do
so will prevent UA data from Las Vegas from reaching the
intended user communities.

Although the effective date for this change is less than the
75-days advised in NWSI 10-1805, a 36-day lead time should be
sufficient when NWS directly informs service providers to make a
priority change in their product meta data to prevent
implementation delays. To check the availability of Las Vegas
products go to:

http://esrl.noaa.gov/raobs/

-Search by "WMO Station Identifier"
-When a blank dialogue window appears, enter: 72388

You should then be able to view the Las Vegas data and metadata.

NWS will issue a follow-on announcement in January 2011 to
include the official site coordinates for the Las Vegas UA
observations.
