Tropospheric Chemistry: Measurements

Earlier Field Campaigns

Some of the field campaigns the Chemical Sciences Laboratory (then the Aeronomy Lab) participated in before 1999:

• 1997 NARE (North Atlantic Regional Experiment): The fundamental aims were to determine the relative importance of natural and anthropogenic ozone sources as well as to quantify the principal mechanisms for the transport of O3 and its precursors from the continental boundary layer to the remote marine troposphere. Measurements were made from the P-3 aircraft. [Cooper, O., J. Moody, D. Parrish, M. Trainer, T. Ryerson, J. Holloway, G. Hübler, F. Fehsenfeld, S. Oltmans, and M. Evans, Trace gas signatures of the airstreams within North Atlantic cyclones: Case studies from the North Atlantic Regional Experiment (NARE '97) aircraft intensive, Journal of Geophysical Research, 2001].
• 1996 STERAO_A (Stratospheric-Tropospheric Exchange: Radiation, Aerosols and Ozone): This campaign was conducted in northeastern Colorado during June and July of 1996 to investigate the production of NOx by lightning, the transport and redistribution of chemical species in the troposphere by thunderstorms, and the temporal evolution of intra-cloud and cloud-to-ground lightning for evolving storms on the Colorado high plains. Measurements were made from the P-3 aircraft and from ground-based instruments. [J. E. Dye, B. A. Ridley, W. Skamarock, M. Barth, M. Venticinque, E. Defer, P. Blanchet, C. Thery, P. Laroche, K.

• 1991+ ONA (Ozone in the North Atlantic): Measurements of CO and O3 were made at surface coastal sites in Nova Scotia and Newfoundland, Canada and in the Azores. The goal of the study was to determine if the pollution plume of North America could be observed at the surface from 500 to 1500 km downwind from the Northeastern US urban corridor over Canada, and as far as 3000 km downwind in the Azores.
