Specifying the light-absorbing properties of aerosol particles in fresh snow samples, collected at the Environmental Research Station Schneefernerhaus (UFS), Zugspitze [PDF]

Atmospheric Chemistry and Physics, 2019
Atmospheric aerosol particles like mineral dust, volcanic ash and combustion particles can reduce Earth's snow and ice albedo considerably even by very small amounts of deposited particle mass. In this study, a new laboratory method is applied to measure

Counting on chemistry: laboratory evaluation of seed-material-dependent detection efficiencies of ultrafine condensation particle counters [PDF]

Atmospheric Measurement Techniques, 2020
Condensation particle counters (CPCs) are crucial instruments for detecting sub-10 nm aerosol particles. Understanding the detection performance of a CPC requires thorough characterization under well-controlled laboratory conditions.

The Collection 6 MODIS aerosol products over land and ocean

, 2013
. The twin Moderate resolution Imaging Spectroradiometer (MODIS) sensors have been flying on Terra since 2000 and Aqua since 2002, creating an extensive data set of global Earth observations. Here, we introduce the Collection 6 (C6) algorithm to retrieve

The effect of harmonized emissions on aerosol properties in global models – an AeroCom experiment [PDF]

, 2007
The effects of unified aerosol sources on global aerosol fields simulated by different models are examined in this paper. We compare results from two AeroCom experiments, one with different (ExpA) and one with unified emissions, injection heights, and ...

Recognition of aerosol transmission of infectious agents: a commentary

BMC Infectious Diseases, 2019
Although short-range large-droplet transmission is possible for most respiratory infectious agents, deciding on whether the same agent is also airborne has a potentially huge impact on the types (and costs) of infection control interventions that are ...

The aerosol box

Journal of Anaesthesiology Clinical Pharmacology, 2020
Despite being scientifically unproven, aerosol boxes have quickly risen in popularity during the COVID-19 pandemic. They have been created in various shapes and sizes, as well as materials across the world. Aerosol boxes offer a transparent barrier between the patient and the healthcare personnel, during intubation and may prove to be useful when ...
