Dr. David W. Tarasick

Senior Research Scientist - Atmospheric research using ozonesondes, including field and model process studies of tropospheric ozone

CURRENT S&T / RESEARCH - Conducting research and studies in the following fields:

  • Tropospheric ozone and air quality:  Analysis of ozonesonde data, studies of tropospheric ozone budgets and processes via ozonesondes, dynamical and air quality models. Studies of Arctic surface ozone depletions via ozonesondes and other data
  • Strategic network studies:  IONS (INTEX Ozonesonde Network Study) campaigns; studies of tropospheric ozone budgets and sources over North America, including stratosphere/troposphere exchange (STE) and boreal forest fires, as well as satellite and air quality model validation studies
  • Tropopause processes and dynamics:  Studies of STE via ozonesondes, windprofiler radar, dynamical and air quality models, satellite and other data sources
  • Stratospheric ozone and UV:  Analysis of ozonesonde data; Brewer total ozone and UV data, Balloon-borne measurements of UV and near-IR spectroscopy of middle atmosphere airglow to measure species related to ozone photochemistry
  • Ozone data quality studies: Laboratory, chamber and field work to examine accuracy of response of ozonesondes, particularly to tropospheric ozone
