Atmospheric aerosol particles serve as condensation nuclei for the formation of both, cloud
droplets and atmospheric ice particles. As a result, they exert a substantial influence on the …

Low-cost sensors (LCSs) are widely acknowledged for bringing a paradigm shift in
supplemental traditional air monitoring by air regulatory agencies. However, there is …

We present a method to describe the relationship between particle dry diameter and cloud
condensation nuclei (CCN) activity using a single hygroscopicity parameter κ. Values of the …

Sea spray is one of the largest natural aerosol sources and plays an important role in the
Earth's radiative budget. These particles are inherently hygroscopic, that is, they take-up …

Interactions with water are crucial for the properties, transformation and climate effects of
atmospheric aerosols. Here we present a conceptual framework for the interaction of …

Experimental and theoretical uncertainties in the measurement of cloud condensation nuclei
(CCN) with a continuous-flow thermal-gradient CCN counter from Droplet Measurement …

The hygroscopic properties play a vital role for the direct and indirect effects of aerosols on
climate, as well as the health effects of particulate matter (PM) by modifying the deposition …

We present the results of a multi-season field evaluation of a low-cost optical particle
counting sensor (Purple Air PA-II) that reports mass concentration of particulate matter with …

Atmospheric mineral dust particles can alter cloud properties and thus climate by acting as
cloud condensation nuclei (CCN) that form cloud droplets. The CCN activation properties of …

Understanding the interactions of water with atmospheric aerosols is crucial for determining
the size, physical state, reactivity, and climate impacts of this important component of the …
