In situ characterization of mixed phase clouds using the Small Ice Detector and the Particle Phase Discriminator [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
Mixed phase clouds (MPCs) represent a great source of uncertainty for both climate predictions and weather forecasts. In particular, there is still a lack of understanding on how ice forms in these clouds.

Effective radiative forcing in the aerosol-climate model CAM5.3-MARC-ARG [PDF]

open access: yesAtmos. Chem. Phys. Discuss., https://doi.org/10.5194/acp-2018-118, in review, 2018
We quantify the effective radiative forcing (ERF) of anthropogenic aerosols modelled by the aerosol-climate model CAM5.3-MARC-ARG. CAM5.3-MARC-ARG is a new configuration of the Community Atmosphere Model version 5.3 (CAM5.3) in which the default aerosol module has been replaced by the two-Moment, Multi-Modal, Mixing-state-resolving Aerosol model for ...

Smart Dust for Chemical Mapping

open access: yesAdvanced Materials, EarlyView.
This review article explores the advancement of smart dust networks for high‐resolution spatial and temporal chemical mapping. Comprising miniature, wireless sensors, and communication devices, smart dust autonomously collects, processes, and transmits data via swarm‐based communication.

Distinct response of near surface air temperature to clouds in North China

open access: yesAtmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
Cloud weakens Tmax and increases Tmin, and thus decreases daily temperature range (DTR), which is mainly due to the blocking effects of clouds to downwelling solar radiation and trapping effects to upwelling longwave radiation. However, the relative impacts of clouds on Tmax and Tmin vary with locations, with relatively stronger impact on Tmin and DTR ...

Aerosol Characteristics at a High Altitude Location in Central Himalayas: Optical Properties and Radiative Forcing [PDF]

open access: yes, 2006
Collocated measurements of the mass concentrations of aerosol black carbon (BC) and composite aerosols near the surface were carried out along with spectral aerosol optical depths (AODs) from a high altitude station, Manora Peak in Central Himalayas, during a comprehensive aerosol field campaign in December 2004.

Black Carbon Contribution to the Aerosol Phase and its Scavenged Fraction in Mixed Phase Clouds at the High Alpine Site Jungfraujoch (3580m asl) [PDF]

open access: yes, 2006
The mass fraction of black carbon (BC) in the atmospheric aerosol and its mixing state are important for the direct aerosol climate effect. These properties also determine if BC is incorporated into cloud hydrometeors (i.e. droplets and ice crystals) and

A global perspective on aerosol from low-volatility organic compounds [PDF]

open access: yes, 2010
Global production of organic aerosol from primary emissions of semivolatile (SVOCs) and intermediate (IVOCs) volatility organic compounds is estimated using the global chemical transport model, GEOS-Chem. SVOC oxidation is predicted to be a larger global
