A new method uses condenser microphones and neural networks to estimate droplet radius from resonant frequency.

Aerosols, which have gained a renewed focus due to the COVID-19 pandemic, are solid or liquid particles suspended in air. They can include viruses, bacteria, salt, dust, fungi, and chemical pollutants ...

Respiratory diseases are a challenging problem to treat. Inhalable medicines are a promising solution that depend on the ability to deliver tiny particles known as aerosols to the correct location in ...

This paper describes the retrieval of aerosol size distributions from the measurements of multispectral solar extinction data, by the use of two retrieval methods—a fast approximate method and the ...

Weather and Climate, Vol. 38, No. 1 (2018), pp. 38-57 (20 pages) We present observations of condensation nuclei (CN) and aerosol optical depth (AOD) from a shipboard project using bulk-carrier ships ...

The world is grappling with the worst pandemic in over 100 years. Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus which emerged in China in December ...

When astronomers want to study the thousands of planets they’ve discovered beyond our solar system, one of their best tools is analyzing the light that shines through the planets’ atmospheres from ...
