NATIONAL TECHNICAL INFORMATION MESSAGE 95-13...PART 1 of 2
NATIONAL WEATHER SERVICE HEADQUARTERS
330 PM EDT MON FEB 27 1995
TO: USERS OF NWS OBSERVATIONS AND AVIATION FORECASTS FROM
DENVER'S STAPLETON INTERNATIONAL AIRPORT
FROM: FRED ZBAR
ACTING CHIEF, SERVICES DEVELOPMENT BRANCH
SUBJECT: SUMMARY OF CHANGES RELATED TO THE OPENING OF THE NEW
DENVER INTERNATIONAL AIRPORT AT 0701 UTC FEBRUARY 28,
1995
(THE FOLLOWING INFORMATION WAS PROVIDED BY DIRK STAUBS, NWS DATA
REVIEW GROUP AND CHRIS ALEX, AVIATION SERVICES BRANCH):
NOTE TO NWWS USERS: THE FOLLOWING CHANGE HAS NO IMPACT TO NWWS
USERS.
...THIS IS PART 1 OF A 2-PART MESSAGE...PART 2 WILL FOLLOW...
Effective at 0701 UTC on February 28, 1995, the new Denver
International Airport will begin operations and Stapleton
International Airport will close. Listed below is a summary of
impacts in the observation and forecast programs as a result of
these changes:
STATION IDENTIFIER:
At 0701 UTC February 28th, the identifier DEN will apply to the
new Denver International Airport an will NO LONGER APPLY TO
STAPLETON INTERNATIONAL AIRPORT. [Until 0701 UTC, the identifier
for the new Denver International Airport has been DVX]. After
0701 UTC, the DVX identifier will no longer apply to any Denver
airports.
SURFACE OBSERVATION PROGRAM:
Effective at 0700 UTC, manual surface observations will cease to
be taken at Denver's Stapleton International Airport. The
surface observations at the new Denver International Airport are
automated, produced by the Automated Surface Observation System
(ASOS). Effective at 0701 UTC, the station identifier for
surface observations for the new Denver International Airport
will be DEN.
For AFOS users there will be NO change necessary in the PIL
to accommodate the change in observation, as long as DENSAODEN is
stored in your database. At 0701 UTC February 28th, the PIL for
the ASOS observation from the new Denver International Airport
will change from DENSAODVX to DENSAODEN (which is the existing
PIL for the SAO from Denver's Stapleton International Airport).
The observation at the Denver International Airport is an NWS
observation from the new airport, located at 39.9 deg N, 104.7
deg W (elevation 5431 feet or 1655.8 meters).
NOTE: DENSAODEN will contain manual surface observations for
Stapleton International Airport until 0700 UTC. Beginning at
0701 UTC, DENSAODEN will contain automated ASOS surface
observations for the new Denver International Airport. In
addition, the DENSAODVX PIL will no longer exist and can be
deleted at your convenience.
For Family of Services users and other direct NWS
Telecommunication Gateway (NWSTG) users, starting at 0701 UTC,
the ASOS observation for the new Denver International Airport
will be included in the FAA-sourced SAO collective SAUS5 KNKA
under the DEN identifier rather than in the NWS-sourced SAO
collective SAUS80 KWBC. ASOS observations that were previously
available under the identifier DVX in the SAUS5 KNKA collective
will be found under the DEN identifier in that same collective.
AVIATION TERMINAL FORECASTS:
Beginning with the scheduled FT at 1900 UTC February 27th,
WSFO Denver will prepare terminal forecasts (FTs) for both the
Stapleton International Airport and the new Denver International
Airport. BETWEEN 1900 UTC FEBRUARY 27TH AND 0700 UTC FEBRUARY
28th ONLY, FTs for both Stapleton International Airport (DEN) and
the new Denver International Airport (DVX) will appear under the
PIL DENFTADEN (FTUS80 KWBC collective for external users). A
remark will be included at the end of the FT to clarify which FT
applies to which airport.
At 0700 UTC, the FT for Denver (DENFTADEN; FTUS80 KWBC) will be
amended, corresponding to the opening of the new Denver
International Airport. At that time, DENFTADEN (FTUS80 KWBC)
will contain only the FT for new Denver International Airport.
After 0700 UTC, the next scheduled FT for DEN (the new Denver
International Airport) will at 1000 UTC February 28th. After
0700 UTC February 28th, no FTs will be prepared for Stapleton
International Airport.
...PART 2 OF THIS MESSAGE WILL FOLLOW. IT CONTAINS INFORMATION
ABOUT THE CHANGES IN THE SYNOPTIC AND UPPER AIR OBSERVATION
PROGRAMS AT DENVER...

SYNOPTIC OBSERVATIONS:
Also on February 28th, beginning after 0701 UTC, the manual
synoptic observation for Denver, previously available under AFOS
PIL DENSSMDEN, will be automatically generated by computer at the
NWS Telecommunication Gateway based on the ASOS surface
observation at Denver International Airport. The automated
synoptic observation will be found in the automated synoptic
collective available in AFOS PIL NMCSSM71 (WMO header SMUS71
KWBC) under the WMO block and station identifier of 72565.
NOTE: The last manual synoptic observation for Stapleton
International Airport will be taken at 0600 UTC February 28th.
The first automated synoptic observation for Denver International
Airport will be generated at 1200 UTC February 28th. In
addition, the DENSSMDEN PIL will no longer be transmitted on AFOS
and can be deleted at your convenience.
UPPER AIR OBSERVATIONS:
Upper air observations will continue to be taken at the
Stapleton International Airport. In order to accommodate that,
the station identifier of the upper air products (listed below)
will change to DNR (the station identifier for Stapleton
International Airport), effective at 1200 UTC February 28th. For
AFOS users the old and new PIL headers are listed below:

The Stapleton International Airport location (DNR) remains at
39.8 deg N, 104.9 deg W. The elevation is 5274 feet or 1608
meters, which is a CORRECTION made since National Technical
Information Message 95-12, which was sent on February 24, 1995.
The WMO block and station number for Stapleton International
Airport remains as 72469. Therefore, NO changes are required for
Family of Services users and other direct NWS Telecommunication
Gateway users as the upper air observations for Denver, Colorado,
will continue to be included in the following four collectives
under the block and station number of 72469:
UJUS81 KWBC
USUS80 KWBC
UJUS82 KWBC
UXUS99 KWBC
Individuals who maintain upper air decoders are reminded to
update any station information files with the new identifier
(DNR) for the upper air observation location at Stapleton
International Airport.
