Towards a UK Airborne Bioaerosol Climatology: Real-Time Monitoring Strategies for High Time Resolution Bioaerosol Classification and Quantification

Biological particulate matter (BioPM) is a poorly constrained, ubiquitous, and diverse subset of atmospheric aerosols. They influence climate, air quality, health via many mechanisms, spurring renewed interest in constraining their emissions to elucidate impacts. In order build the framework required assess role BioPM these multidisciplinary areas, it necessary develop robust, high time-resolution detection methodologies so that can be understood characterized. this study, we present ambient results from intensive monitoring at UK peri-urban coastal ground sites using real-time bioaerosol spectrometers. We demonstrate utility new dimensional reduction-driven classification scheme, where laboratory sample training data collected ChAMBRe facility were used generate broad taxonomic class time series key species interest. show general trends representative classes, spanning spring, early summer, autumn periods between 2019 2021.
