Secondary ice production – no evidence of efficient rime-splintering mechanism [PDF]
Atmospheric Chemistry and PhysicsMixed-phase clouds are essential for Earth’s weather and climate system. Ice multiplication via secondary ice production (SIP) is thought to be responsible for the observed strong increase in ice particle number concentration in mixed-phase clouds.

The Myth of Supervenient Microphysicalism [PDF]
Philosophica: International Journal for the History of Philosophy, 2016 In this paper I focus on the analysis of the concept of the physical and its implications for the formulation of physicalism. Most of the paper is “negative,” insofar as it intends to show why the most accepted formulation of physicalism, the theory of the supervenience or complete determination of the empirical phenomena by the microphysical ...

Geophysical Research Letters, 2023 Many studies have performed microphysical retrievals using radars of different frequencies, platforms, and methodologies. However, little is known about the consistency of retrievals derived from different radar platforms (i.e., airborne or spaceborne vs.

Marine carbohydrates and other sea spray aerosol constituents across altitudes in the lower troposphere of Ny-Ålesund, Svalbard [PDF]
Atmospheric Chemistry and PhysicsMarine combined carbohydrates in aerosol particles (CCHOaer) have the potential to influence cloud formation and properties, but it remains unclear to what extent they reach altitudes relevant for cloud processes.

Global Microphysical Sensitivity of Superparameterized Precipitation Extremes
Earth and Space Science, 2021 A recent study found statistically significant differences in extreme precipitation distributions over the contiguous United States (CONUS) when changing the microphysics scheme in a superparameterized global climate model.

Measurement report: Contribution of atmospheric new particle formation to ultrafine particle concentration, cloud condensation nuclei, and radiative forcing – results from 5-year observations in central Europe [PDF]
Atmospheric Chemistry and PhysicsAs an important source of sub-micrometer particles, atmospheric new particle formation (NPF) has been observed in various environments. However, most studies provide little more than snapshots of the NPF process due to their underlying observations being

Machine Learning the Warm Rain Process
Journal of Advances in Modeling Earth Systems, 2021 Clouds are critical for weather and climate prediction. The multiple scales of cloud processes make simulation difficult. Often models and measurements are used to develop empirical relationships for large‐scale models to be computationally efficient ...

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces
Geophysical Monograph Series, Page 103-116., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
