Linkage Between Atmospheric Rivers and Overshooting Convection and Their Roles on UTLS Water Vapor During the North American Monsoon: Insight From DCOTSS

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Overshooting convection significantly impacts the composition of the upper troposphere and lower stratosphere (UTLS), yet its linkage to Atmospheric Rivers (ARs) remains poorly understood. This study investigates how ARs modulate environmental conditions and moisture distribution associated with overshooting convection in the central and ...

Investigation of the effective peak supersaturation for liquid-phase clouds at the high-alpine site Jungfraujoch, Switzerland (3580 m a.s.l.) [PDF]

, 2014
Aerosols influence the Earth's radiation budget directly through absorption and scattering of solar radiation in the atmosphere but also indirectly by modifying the properties of clouds. However, climate models still suffer from large uncertainties

The Importance of Tire Wear Particles for Atmospheric Ice Nucleation

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tire wear particles (TWPs) are prevalent microplastic particles in the atmosphere and pose significant environmental and health risks to humans. Here, we investigated the ice nucleation activity (INA) of TWPs under mixed‐phase cloud conditions (∼−20.0°C < T < −5.0°C) and its changes caused by different environmental exposures, including UV and

Chemical composition of ambient aerosol, ice residues and cloud droplet residues in mixed-phase clouds: single particle analysis during the Cloud and Aerosol Characterization Experiment (CLACE 6) [PDF]

, 2009
Two different single particle mass spectrometers were operated in parallel at the Swiss High Alpine Research Station Jungfraujoch (JFJ, 3580 m a.s.l.) during the Cloud and Aerosol Characterization Experiment (CLACE 6) in February and March 2007.

What Is Triggering Ice in Mixed‐Phase Clouds: A Process Analysis With ECHAM6.1‐HAM2.3 Using the Factorial Method

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Mixed‐phase clouds can be found at temperatures between 0 and −38° ${}^{\circ}$C and consist of supercooled cloud droplets and ice crystals. The phase of mixed‐phase clouds is crucial for the radiation budget, which determines the atmosphere's energy balance.

Observation of Cirrus Cloud [PDF]

Nature, 1875
I HAVE just received from the Meteorological Observatory at Upsal, Sweden, a number of blank forms (with instructions in English) for observations of the directions of the cirrus cloud. Copies of these forms I shall have much pleasure in supplying to anyone who may be willing to make observations of these clouds, the systematic and extensive ...

Influence of ice crystal shape on retrieval of cirrus optical thickness and effective radius: A case study

, 2009
Airborne measurements of spectral upwelling radiances (350â  2200 nm) reflected by cirrus using the Spectral Modular Airborne Radiation measurement sysTem (SMART)-Albedometer were made over land and water surfaces.
