ADMINISTRATIVE MESSAGE
NATIONAL WEATHER SERVICE HEADQUARTERS WASHINGTON DC
130 PM EST WED DEC 28 1994
TO: ALL NWS OFFICES AND NWS EMPLOYEES
FROM: JAMES P. TRAVERS, CHIEF, OPERATIONS DIVISION, OFFICE OF
METEOROLOGY
SUBJECT: ULTRAVIOLET INDEX (UVI) DISSEMINATION
Effective immediately, offices may discontinue broadcasts of UVI on
NOAA Weather Radio (NWR) during the winter due to generally low UVI
values. Some offices in subtropical areas may want to continue these
broadcasts through the winter, depending on local factors and user
needs. NWR broadcasts of UVI generally should resume nationwide
approximately Monday, April 3, 1995. Some offices may resume these
broadcasts at an earlier or later date according to local factors and
user needs.
There will be no discontinuance of the UVI on other dissemination
systems. The Climate Analysis Center of NMC will continue to issue
the experimental national UVI product once a day around 1800 UTC for
the 58 cities. This product is transmitted on AFOS/NOAA Weather Wire
under the identifier NMCUVICAC and the Family of Services under AEUS41
KWBC.
The UVI product is expected to become official (no longer
experimental) on April 3. The "beta" tests at several forecast
offices to demonstrate skill in local adaptive forecasting of the UVI
with same-day morning update will resume next year.
