Observational chemical component data of submicrometer aerosols sampled at the Okhotsk Tower, Mombetsu from August 2023 to August 2025

A two-year ground-based observation of submicrometer aerosols was conducted at a coastal site (Okhotsk Tower, Mombetsu) in the southern Sea of Okhotsk. The dataset in the excel sheet contains the sampling period, concentrations of components and stable carbon isotope ratios for each aerosol sample. This dataset is for Fang et al. submitted to Journal of Geophysical Research: Atmospheres.
