NATIONAL TECHNICAL INFORMATION MESSAGE 95-12
NATIONAL WEATHER SERVICE HEADQUARTERS
200 PM EDT FRI FEB 24 1995
TO: USERS OF NWS UPPER AIR PRODUCTS FROM DENVER, COLORADO
FROM: FRED ZBAR
ACTING CHIEF, SERVICES DEVELOPMENT BRANCH
SUBJECT: CHANGE IN UPPER AIR OBSERVATION PRODUCT HEADERS AT
DENVER, COLORADO
REFERENCE: NATIONAL TECHNICAL INFORMATION MESSAGE 95-10, DATED
FEBRUARY 21, 1995
(THE FOLLOWING INFORMATION WAS PROVIDED BY DIRK STAUBS, NWS DATA
REVIEW GROUP):
NOTE TO AFOS AND NWWS USERS: THE FOLLOWING CHANGE HAS NO IMPACT
TO NWWS USERS.
As documented in the reference message issued earlier this week,
effective at 0701 hours UTC on February 28, 1995, the identifier for
the Denver International Airport will permanently change from DVX to
DEN. Also at that time the identifier for the old Stapleton
International Airport location and the NWS Forecast Office in Denver
(which is located at Stapleton International Airport) will change
from DEN to DNR. As a result, the AFOS PIL headers for upper air
observations that will continue to be taken at the Stapleton
International Airport location will also change.
To reiterate what is changing, upper air observations will continue to be
taken at Stapleton International Airport. The change is only the location
identifier associated with the upper air observations taken at Stapleton
International Airport. For AFOS users the following new PIL headers
will become effective on February 28, 1995, at 1200 hours UTC to
accommodate the new site identifier:
OLD PIL HEADERS: NEW PIL HEADERS:
DENABVDEN DENABVDNR
DENFZLDEN DENFZLDNR
DENMANDEN DENMANDNR
DENSGLDEN DENSGLDNR
The Stapleton International Airport location (DNR) remains at
39.8 deg N, 104.9 deg W (elevation 5330 feet or 1625 meters), and the
WMO block and station number remains as 72469. Therefore, NO changes
are required for Family of Services users and other direct NWS
Telecommunication Gateway (NWSTG) 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
For AFOS users, an AFOS Change Notice will be sent out under the AFOS
PIL cccADADRG sometime next week. If any other PIL headers issued by
WSFO Denver change as a result of this identifier change you will be
notified via GENOTS and change notices.
Users 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.
If you have any questions or concerns about this change, contact
Dirk Staubs, at (301) 713-1373 or via e-mail at the following
