Fenceline VOC Measurements Using Mobile Platforms SDMP.FY25.74.0

This dataset contains final data for the manuscript titled "Comparing short-term volatile organic compound measurements in fenceline environments using multiple mobile air monitoring platforms and methods", Coughlin et al. This dataset and manuscript describes a two-week field campaign where a team cross-compared air monitoring instrumentation in a mobile monitoring format. The scripts included in the data repository process raw data, generate visualizations, and compare measurements from various instruments including a PTR-ToF-MS, UV-DOAS, GC-MS, and SIFT-MS. Different sampling resolutions are handled within the scripts using rolling averages The Methods and Materials within the article describes the monitoring instrumentation that was used and the sampling methodology.
