Cloud microphysics and aerosol indirect effects in the global climate model ECHAM5-HAM [PDF]

, 2007
The double-moment cloud microphysics scheme from ECHAM4 has been coupled to the size-resolved aerosol scheme ECHAM5-HAM. ECHAM5-HAM predicts the aerosol mass and number concentrations and the aerosol mixing state.

Active aerosols

Optics Express, 2022
We report the dynamics and control of the orientational and positional order of ensembles of gold nanorods suspended in air at standard temperature and pressure using externally applied electric fields, demonstrating an active aerosol. Light filter, valve and gradient responses are shown, establishing active aerosols as a unique type of optical element

Atmospheric aerosol attenuation effect on FD data analysis at the Pierre Auger Observatory [PDF]

, 2019
The atmospheric aerosol monitoring system of the Pierre Auger Observatory has been operating smoothly since 2004. Two laser facilities (Central Laser Facility, CLF and eXtreme Laser Facility, XLF) fire sets of 50 shots four times per hour during FD ...

Update on the Science and Technology of Diesel Particulate Filters

KONA Powder and Particle Journal, 2014
As diesel emission regulations become more stringent, diesel particulate filters (DPFs) have become possibly the most important and complex diesel emission control device. This paper provides an update on the science

Synthesis of satellite (MODIS), aircraft (ICARTT), and surface (IMPROVE, EPA-AQS, AERONET) aerosol observations over eastern North America to improve MODIS aerosol retrievals and constrain surface aerosol concentrations and sources [PDF]

, 2010
We use an ensemble of satellite (MODIS), aircraft, and ground-based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new ...

Size-resolved condensation sink as an approach to understand pathways how gaseous emissions affect health and climate [PDF]

Atmospheric Chemistry and Physics
Vapour condensation onto existing aerosol particles is important regarding aerosol health and climate effects. Existing particles can act as carriers for toxic vapours into the human respiratory tract.
