Atmospheric particles and clouds: a pH overview
The article reviews the current state of knowledge on the acidity of particles and cloud droplets in the atmosphere. Observationally constrained pH estimates indicate that fine particles are ubiquitous but spatially and temporally limited, while clouds and fogs are also generally acidic.
Possible Conflicts of Interest
None identified
Identified Weaknesses
different definitions of pH are used
pH has many different approximations, but is only directly measurable for dilute solutions, meaning that the pH values shown in the literature may not be equivalent to the exact or even the approximate measures, which will affect the accuracy of the results.
Rating Explanation
This review synthesized the current literature on the acidity of atmospheric condensed phases. Aerosol acidity is an important field in atmospheric sciences because it affects health, ecosystems, climate, and environmental management. While this field has seen rapid growth in the literature, few observationally constrained datasets exist for model evaluation, a challenge that is addressed in this work.
