Surface air quality and meteorological measurements
only provide a limited amount of the information required
to understand the processes governing pollution transport
and dispersion, noise propagation, and the like. A complete
understanding requires a three-dimensional investigation
of the boundary layer that can only be achieved by physical
measurements. T&B Systems is unique in our experience
with a variety of boundary layer measuring techniques that
includes:

· Radar Wind Profilers

· Radio Acoustic Sounding Systems (RASS)

· Doppler Acoustic Sounding Systems (SODAR)

· Balloon-borne Meteorological Soundings (Rawinsonde)

· Balloon-borne Ozone Soundings (Ozonesonde)

· Tethered Balloon Soundings

· Tower measurements

During the recently completed Central California Air
Quality Studys (CCOS and CRPAQS), T&B Systems'
staff were responsible for three SODAR site operations,
rawinsonde and ozonesonde measurements at four
locations, and Tower-based meteorological and
air quality measurements at several levels to 1,600 feet.
In addition, other members of our staff not
directly involved in the field measurements were
responsible for the quality assurance oversight the complete network of sodars, radar profiler and RASS systems (25 sites).

Moreover, T&B Systems owns and operates a GPS-based rawinsonde system enabling winds to be measured with unsurpassed accuracy and temporal/vertical resolution
