Description:

Since the early eighties, the NOAA/Air Resources Laboratory/Field Research Division (ARL/FRD) has released perfluorocarbon tracers in a number of field programs designed to measure long-range atmospheric transport over regional and continental scales. In the summer of 1999, ARL/FRD participated in a field program designed to understand the long-range transport of visibilityreducing particles from regional sources in the U.S. and Mexico and to quantify the contributions of specific U.S. and Mexican sources (or source regions) possibly responsible for poor visibility at Big Bend National Park. The Big Bend Regional Visibility and Observational (BRAVO) Study field program was conducted over four months, from July through the end of October 1999. Tracer released as part of the BRAVO Study occurred over a four-month period, included three different release schedules to provide time stamping, and required two release systems to be relocated to tag the influence of different sources at the mid-point of the study period. ARL/FRD developed new, automated release systems for the BRAVO Study to accomplish the release in an efficient and costeffective manner. The design of these systems is described in detail. The systems released the tracer as planned, with only four minor problems resulting from equipment malfunctions. The data recovery rate was 99.6%. The calibration and data analysis methods are described in detail and the data file structure outlined.
