Chemical composition and size of individual indoor aerosol particles during cooking experiments in wintertime Fairbanks, Alaska, 2022

The Alaskan Layered Pollution and Chemical Analysis field campaign was conducted in Fairbanks, Alaska from January to February 2022. Individual aerosol particles were measured indoors with particle sizing instrumentation and an aerosol time-of-flight mass spectrometer during cooking experiments inside a residential house (64.850°N, 147.676°W). The goal of this work was to understand the chemical composition and size of individual indoor aerosol particles while cooking experiments were conducted. Here we report indoor aerosol number concentrations, aerosol number mode diameters, average individual aerosol particle mass spectra, and chemically-resolved number fractions during nine cooking experiments. We also report chemically-resolved number fractions with particle diameter.
