Chemical Tracer Measurements https://data.eol.ucar.edu/dataset/648.004 Summary These Chemical Tracer Measurements are part of the BACS (BioAerosol and Convective Storm) campaign. The purpose of the BACS campaign was to characterize the dynamics between convective storms and bioaerosols in a grassland environment. The focus of PI Stone’s group was on characterizing bioaerosol types, concentrations, and sizes during quiescent and convective conditions using offline techniques combined with online instrumentation. These measurements will provide better insight into the impact of convective storms on bioaerosols, allowing for improved modelling and predictions. This archive is for chemical tracer measurements of samples collected using high flow impactors in a soil plot located northwest of the NEON flux tower. The campaigns took place from May 23 – June 17, 2022, and from May 22 – June 23, 2023, and were conducted in northeastern Colorado, with a latitude of 40.816284 N, a longitude of 104.746390 W, and an average altitude of 1654 m. Samples were collected continuously throughout both campaigns, with sample durations ranging from 6-24 hours.
