UTLS Egrett: Airborne atmospheric chemistry and meteorological observations over Aberystwyth, Mid-Wales
The Aberystwyth Egrett Experiment: Gravity Waves, Turbulence, Mixing and Filamentation in the Tropopause Region is a Upper Troposphere Lower Stratosphere (UTLS) Round 2 project led by Dr J. Whiteway and Dr G. Vaughan, Department of Physics, University of Wales, Aberystwyth.
Dataset contains: airborne measurements, by the Egrett aircraft, of turbulence, ozone, water vapour, CH4 and CFCs; ground based measurements, by the NERC MST Radar, of atmospheric structure, mesoscale dynamics, and turbulence; balloons measurements of ozone, water vapour, wind, temperature and pressure; Lidar of ozone, water vapour, temperature and cirrus clouds.
Airborne measurements: A unique stratospheric research aircraft, the Egrett aircraft, performed 10 separate flights in the UTLS region above Aberystwyth. The Egrett was equipped with advanced instrumentation for measurements of turbulence, ozone and water vapour.
Ground based measurements: The ground based facilities at Aberystwyth were operated to their full capacity during the Egrett campaign. The NERC MST Radar provided measurements of atmospheric structure, mesoscale dynamics, and turbulence. Balloons carryed instruments for measuring ozone, water vapour, wind, temperature and pressure. Three separate lidar systems provided measurements of ozone, water vapour, temperature and cirrus clouds.
Analysis of gravity waves and turbulence: The above measurements were conducted when gravity waves were breaking and causing turbulence. The combination of the Egrett and ground based measurements have been used to determine if this process is significant for transport of chemical constituents in the UTLS region. These measurements also provided a new basis for testing theories and models of the wave breaking process.
Analysis of filamentation: The Egrett aircraft was directed to fly through regions of filamentation in the lower stratosphere. This provided new data to test theories and models of mixing through turbulence at the edges of filaments.
