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

Time for Cloud? Design and implementation of a time-based cloud resource management system

, 2014
The current pay-per-use model adopted by public cloud service providers has influenced the perception on how a cloud should provide its resources to end-users, i.e. on-demand and access to an unlimited amount of resources.

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 ...

Systematic review of the impact of emissions from aviation on current and future climate [PDF]

, 2007
Aviation emissions have an impact on the global climate, and this is consequently an active area of research worldwide. By adapting replicable and transparent systematic review methods from the field of evidence-based medicine, we aim to synthesise ...

Cirrus formation regimes – data-driven identification and quantification of mineral dust effect [PDF]

Atmospheric Chemistry and Physics
The microphysical and radiative properties of cirrus clouds are strongly dependent on the ice nucleation mechanism and origin of the ice crystals. Due to sparse temporal coverage of satellite data and limited observations of ice-nucleating particles ...

The accommodation coefficient of water molecules on ice – cirrus cloud studies at the AIDA simulation chamber [PDF]

Atmospheric Chemistry and Physics, 2013
Cirrus clouds and their impact on the Earth's radiative budget are subjects of current research. The processes governing the growth of cirrus ice particles are central to the radiative properties of cirrus clouds.

Buoyancy Flux and Its Environmental Modulation in the Vertical Development of Shallow Cumulus in the Central Amazon

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract This study investigates the vertical development of shallow cumulus (ShCu) clouds in the Central Amazon (CAMZ) by combining large‐eddy simulations (LES) with observational data from the GoAmazon2014/5 campaign. Analyses of turbulent kinetic energy budgets, updraft mass flux, moisture flux, and surface fluxes across cloud sizes indicate that ...

An Analysis of Hurricane Eyewall Ice Using a Novel Lagrangian Trajectory and Growth Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Ice crystals in tropical cyclones (TCs) remain infrequently observed and difficult to model using Eulerian microphysics parameterizations. To better understand TC eyewall ice crystal processes, the Ice Crystal Trajectory Growth (ICTG) model, previously applied to an idealized squall line, was used to simulate Lagrangian ice crystal ...

Dehydration potential of ultrathin clouds at the tropical tropopause. [PDF]

, 2003
We report on the first simultaneous in situ and remote measurements of subvisible cirrus in the uppermost tropical troposphere. The observed cirrus, called UTTCs (ultrathin tropical tropopause clouds), are the geometrically (200–300 m) and optically (τ ≈
