Trajectory Data Set from the study on the 2017 BC wildfire detection
Introduction
This data repository provides access to the trajectory data calculated for the study by Hooghiem et al. in Atmos Chem. Phys. (2020). In this study, wildfire-influenced airmasses were found in AirCore measurements over Sodankylä (Finland) that could be traced back to a wildfire in British Columbia (Canada) in August 2017. For this effort, back trajectories from the observations were calculated by the trajectory module of CLaMS. As the additional vertical velocity component caused by diabatic heating due to the smoke is not included in CLaMS, the simulation was performed piece-wise. The vertical displacement was determined from a Match with subsequent CALIOP satellite observations of the exhaust plume.
