(SLOC), the system, which includes

Campbell Scientific automated weather

stations, relies upon meteorologists from

the public, private, and academic sectors

of the atmospheric science community.

It spans the network of indoor Olympic

venues along the Wasatch Front (the met-

ropolitan corridor west of the Wasatch

Mountains that is home to the bulk of

Utah's population and runs 110 km at

~1,300 m in elevation) and outdoor

venues on the eastern flanks of the

Wasatch Mountains which range in

elevation from 2,826 m (9,270 ft) at

the top of the men's downhill course, to

1,670 m (5,480 ft) at the cross country/

biathlon course. The variations in weath-

er and climate from venue to venue are

tremendous.

Forecasting responsibilities are like-

wise varied. Olympic weather support

has traditionally been led by the host

country's primary weather agency. But

weather forecasting duties for the 2002

Winter Games will be shared by forecast-

ers from the National Weather Service

and KSL, Salt Lake City's National

Broadcasting Company (NBC) affiliate.

Individuals from other agencies, including

the NWS Salt Lake Weather Forecast

Office, the NOAA Cooperative Institute

for Regional Prediction (CIRP), the NWS

Western Region Scientific Services

Division, the Aviation Security Operations

Center (ASOC) at Hill Air Force Base,

and the Utah Avalanche Center will pro-

vide data, resources and forecasts for spe-

cific Olympic-related applications. The

SLOC weather support group also

includes weather volunteers, including

undergraduate and graduate students from

the University of Utah and other local res-

idents. Close coordination of all groups

involved, therefore, will be vital if consis-

tent forecasts are to be ensured.

The KSL team consists of 13 private-

sector meteorologists charged with pro-

viding detailed microscale weather fore-

casts for the five outdoor venues.

Assembled by Mark Eubank, KSL chief

meteorologist, the venue forecast team

has extensive experience forecasting

northern Utah weather. Venue forecasters

will have on-site access to the latest

weather observations, graphics, and

model data. Weather forecasts will be

issued three times daily with updates

issued as needed. Forecast fields include:

sky cover, precipitation type and amount,

air temperature, wind direction, wind

speed, wind gusts, wind chill, visibility,

humidity, and snow temperature. A joint

weather phone conference will be con-

ducted each morning between forecasters

at the venues, the NWS Salt Lake field

office, and the ASOC. Official manual

weather observations will be started one

hour before each outdoor event begins

and will continue at 15-minute intervals

throughout the event.

Since documentation of weather condi-

tions prior to the Olympics was required

for planning (and during the Games for

operations) weather equipment was

installed at venues and other key locations

in northern Utah beginning in 1996.

Portable weather stations manufactured

by Campbell Scientific, Inc., that were

deployed by the NWS Southern Region

for the 1996 Atlanta Summer Olympic

Games, were made available to the NWS

Western Region after the summer games

were completed. Also during 1996, the

NWS Western Region and the National

Severe Storms Laboratory began a

research project in the vicinity of Salt

Lake City to validate WSR-88D radar

algorithms in regions of complex terrain.

In support of that project, weather equip-

ment was deployed at eight locations

(four within the Wasatch Front and four at

Olympic venues).

Forecasting and weather-data recording

in preparation for the 2002 Olympic

Winter Games have allowed a unique

partnership to evolve since 1996, with

government, commercial, and research

communities sharing weather information

in northern Utah and throughout the west-

ern United States. Initially referred to as

the Utah Mesonet, the collection of data

outside of Utah led to its redesignation as

MesoWest in January 2000. Now, during

February and March 2002, weather obser-

vations will be available from over 278

locations in the northern Utah region.
