California Regional Particulate Air Quality Study (CRPAQS)
PACJET will occur within the time period covered by the
CRPAQS experiment, which is being conducted in the Central Valley of
California to study particulate air pollution. A significant
upper air observing network and land surface processes study site are
being deployed for CRPAQS. This network will prove useful in
providing unique data for verification of forecasts during PACJET and
for the assimilation of vertical profile data into numerical weather
prediction models.

Winter Storms Reconnaissance Program
PACJET will be closely coordinated with the WSR program. As illustrated,
the two experiments cover complementary regions of the data
sparse Pacific ocean, with WSR focused on the central Pacific and PACJET
on the coastal areas. Cooperative plans have been underway for some
time, and will at least consist of coordination on the timing and
location of flight operations. The goals of coordination will be either
to cover the same storm using a sequence of flights, or by focusing all
flights on a single time.

The Hemispheric Observing System Research and Predictability Experiment (THORPEX)
THORPEX is a major experiment being planned for the Pacific Ocean in
2003-2005. PACJET incorporates several components that will aid in
preparing for this large experiment by testing new measurement techniques
that could be of value in THORPEX. In this respect, PACJET helps
accelerate progress toward THORPEX, and increases the chances for its
success. The most relevant testing in PACJET includes:
- Development of buoy-mounted wind profiling. The first prototype was
tested in March 2000 for 5 days on a SCRIPPS buoy. Preliminary
assessment of the data indicates that the key method for suppressing sea
clutter was successful, and thus the investment will be made to harden
the system for protracted deployment, testing, and validation during
PACJET.
- Realistic field testing of a promising UAV, the AEOSONDE. The goal
is to conduct at least one successful flight from Hawaii to the west
coast in the context of a significant storm and with over-the-horizon
communication with the UAV. The capabilities of the AEROSONDE appear to
be well suited to PACJET's goal of measuring the low-level jet. (Fig.
from Greg Holland).
- Testing coordination of up to 4 aircraft in sampling a target
specified by the ensemble transform technique as part of a coordinated
effort with the Winter Storms Reconnaissance program.

IMPROVE
Although the IMPROVE and PACJET experiments each have several
objectives, they share a common goal of better understanding of
microphysical conditions associated with heavy orographic precipitation
on the west coast. Efforts are being made to coordinate the experiments
in a way that helps each better realize its primary goals. For example,
the IMPROVE project's field work in winter 2000/2001 was recently
shifted from November/December 2000 to January/February 2001, which now
overlaps the observing period for PACJET, and a profiler that will be
deployed along the coast for PACJET will be sited to optimize its value
for IMPROVE. Numerous other possibilities for coordination and synergy
will be fully explored.
