Polyurethane foam equipped passive air samplers are a valuable tool for monitoring atmospheric semivolatile organic pollutants, but are often complicated due to the need for an accurate sampling rate (Rs). Here, we describe the development and implementation of a web-based Rs interface that allows for a user-friendly way of determining and visualizing accurate modeled Rs values. The web interface provides access to the previously published model without the need for proprietary software (MATLAB) or coding experience. The precalculated Rs avoids unnecessary computation time, providing the user with fast results and visualizations of the sampler behavior during deployment. Supported by the National Aeronautics and Space Administration’s Modern Era Retrospective-Analysis for Research and Applications meteorological data at both 2 and 10 m heights above ground level, users can determine Rs for any location on the globe. Users can select prepopulated compounds (e.g., polychlorinated biphenyls) or manually enter compounds, enter sample information individually or upload them batch-wise, run the model, and export data to a CSV to further integrate with the data analysis workflow. Additionally, an implementation of the same model is available in R, along with scripts to process meteorological data.
