ABK Arbuckle Intrabasin transport Location provides coverage of predominant
summer flow through Sacramento Valley.
ABU N. of Auburn, S.
of Grass Valley
Upslope/downslope flow,
downwind of major area
source
ACP Angel's Camp Upslope/downslope flow,
complex terrain for
challenging model evaluation
Site to monitor possible summer eddy flow,
vertical temperature structure evolution, model
input and evaluation data. Downwind of
Sacramento area source.
Served as site to capture eddy flow, mixing,
vertical temperature structure, model input and
evaluation data during SJVAQS/AUSPEX

Northern boundary transport,
synoptic conditions
Onshore/offshore transport
Positioned to monitor transport up the valley,
low level nocturnal jet flow, and Fresno eddy
flow patterns. Collocated with tall tower.
Fulfill needs of National Weather Service and
Beale AFB flight operations; existing long-term
site.
Fulfill needs of National Weather Service;
existing long-term site
CAR Carizo Plain Interbasin tranport. Monitor tranport between San Joaquin Valley
and South Central Coast Air Basins.
CRG Corning Nothern Valley barrier,
characterize Northern SV
convergence zone.
To observe southerly barrier winds along the
Sierra Nevada which may be a transport
mechanism. May characterize extent of northerly
flow into SV for some scenarios.
DAX Sacramento Intrabasin transport Fulfill needs of National Weather Service;
existing long-term site
EDI Edison Interbasin transport through
Tehachapi Pass. Downwind
of major source.
Site to observe possible divergence flow at
southern end of the valley, low level jet flow,
and eddy flows. Data from SJVAQS/AUSPEX
taken at Oildale supports these observations.
Downwind of Bakersfield area source.
EDW Edwards AFB Intrabasin transport Existing long term site. Transport through
Tehachapi Pass, desert mixed layer, synoptic
conditions.
