Upper-air data collection during CAPTEX. Final report
This report describes the results of the operation of a network of 10 rawinsonde upper-air stations by Battelle-Northwest during the CAPTEX-83 Long Range Tracer Experiment. CAPTEX-83 was a multiagency-sponsored research program on atmospheric transport and diffusion on the 1000-km scale. The purpose of these upper-air stations was to increase the temporal and spatial resolution of the measurement of the winds and thermodynamic properties of the atmosphere in the boundary layer. Battelle-Northwest contracted with the Electric Power Research Institute (EPRI) in April 1983 to provide the personnel, equipment, and facilities necessary to operate the network of 10 upper-air stations within the CAPTEX tracer target area, and to process and report the data to EPRI and the CAPTEX data center. The CAPTEX tracer target area was the northeastern US. Six of the upper-air stations were established in two triangular arrays - one in Ohio and one in central New York. The four remaining stations were located near Burlington, Vermont, State College, Pennsylvania, Andover, New Jersey and Gravenhurst, Ontario. Routine operation of the stations began September 12, 1983 and continued until October 30. Seven tracer experiments were conducted with five tracer releases from the Dayton, Ohio, site and two from the Sudbury, Ontario, release site. Recommendations for improving future experiments of this type include increasing the onsite data processing capability for near-real-time data validation, providing a direct data link from the field sites to the NOAA computer facility, and determining the reliability of the CAPTEX-83 mode of operation to realistically measure the scale of atmospheric motion governing regional-scale transport phenomena. 1 reference, 2 figures, 10 tables.
