UTLS Project Information
The Terrain-induced Rotor Experiment (T-REX) is a coordinated effort to explore the structure and evolution of atmospheric rotors. The main scientific objective of T-REX is a comprehensive study of the coupled mountain-wave, rotor, and boundary-layer system. T-REX field activities took place in Owens Valley in March and April 2006. |
 In collaboration with the T-REX Science Team (contacting PI: Vanda Grubisic), UTLS initiative scientists participated the field campaign to investigated the chemical signature of mountain waves near the tropopause.
Using a small suite of in situ tracer measurements (O3, CO and H2O vapor) and analyses of meteorological variables, exchange and mixing between the stratosphere and troposphere were probed during the field experiments. |
T-REX Campaign
The main scientific objective of the Terrain-induced Rotor Experiment (T-REX) is a comprehensive study of the coupled mountain-wave, rotor, and boundary-layer system. Some complimentary scientific issues include stratospheric-tropospheric exchange and structure and evolution of thecomplex terrain boundary layer in the absence of rotors. The comprehensive T-REX data sets will also represent a unique test bed for the validation of numerical models, and are expected to be instrumental inachieving further significant improvementsin mesoscale and microscale  modeling and in the prediction of aviation hazards, downslope windstorms, and aerosol transport and dispersion. |
