Contrasting local and long-range-transported warm ice-nucleating particles during an atmospheric river in coastal California, USA [PDF]

, 2019
Ice-nucleating particles (INPs) have been found to influence the amount, phase and efficiency of precipitation from winter storms, including atmospheric rivers.Warm INPs, those that initiate freezing at temperatures warmer than -10°C, are thought to be ...

Effects of regional-scale and convective transports on tropospheric ozone chemistry revealed by aircraft observations during the wet season of the AMMA campaign [PDF]

, 2009
The African Monsoon Multidisciplinary Analyses (AMMA) fourth airborne campaign was conducted in July–August 2006 to study the chemical composition of the middle and upper troposphere in West Africa with the major objective to better understand the ...

Investigating the Atmospheric Microbial Ecosystem Through Theory, Bioenergetics, and Numerical Modeling: A Breath of Fresh Air for Aeromicrobiology

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract The atmosphere may constitute the Earth's largest microbial ecosystem, yet it remains the least understood. While microorganisms can persist and may even thrive in the polyextremes of the Earth's atmosphere, it is still unknown whether the atmosphere sustains an active microbial community.

Improving trajectory calculations by FLEXPART 10.4+ using deep learning inspired single image superresolution

, 2022
Abstract. Lagrangian trajectory or particle dispersion models as well as semi-Lagrangian advection schemes require meteorological data such as wind, temperature and geopotential at the exact spatio-temporal locations of the particles that move independently from a regular grid. Traditionally, this high-resolution data has been obtained by interpolating

Influence of biomass burning and anthropogenic emissions on ozone, carbon monoxide and black carbon at the Mt. Cimone GAW-WMO global station (Italy, 2165 m a.s.l.) [PDF]

Atmospheric Chemistry and Physics, 2013
This work investigates the variability of ozone (O₃), carbon monoxide (CO) and equivalent black carbon (BC) at the Italian Climate Observatory "O. Vittori" (ICO-OV), part of the Mt. Cimone global GAW-WMO station (Italy).

Connectivity of Nocturnal Cold‐Air Flows for Urban Heat Island Mitigation: Introduction of the Cold‐Air Trajectory Calculator KLATra

Meteorological Applications, Volume 32, Issue 4, July/August 2025.
The newly developed trajectory calculator KLATra was used in a cold‐air connectivity analysis. This approach allows for the identification and assessment of the relevance of specific cold‐air formation areas for urban heat island mitigation and may serve as a valuable planning tool for decision‐making.

Autonomous Year‐Round Measurements of O3 ${\mathbf{O}}_{\mathbf{3}}$, CO $\text{CO}$, CH4 ${\text{CH}}_{\mathbf{4}}$, and N2O ${\mathbf{N}}_{\mathbf{2}}\mathbf{O}$ in the High Arctic With the Atmospheric Emitted Radiance Interferometer

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.
Abstract Despite its status as a proverbial canary in the coal mine for global climate change, the Arctic has limited observational data, particularly during polar night. Longwave atmospheric emission has been recorded since 2006 at the Polar Environment Atmospheric Research Laboratory, located at Eureka, Nunavut, Canada (80° ${}^{\circ}$N).

The role of the Amazon Basin moisture in the atmospheric branch of the hydrological cycle: a Lagrangian analysis [PDF]

Hydrology and Earth System Sciences, 2014
We used a Lagrangian model (FLEXPART) together with the 1979–2012 ERA-Interim reanalysis data to investigate the role of the moisture in the Amazon Basin in the regional hydrological budget over the course of the year.

A Unique Mechanism of Ozone Surges Jointly Triggered by Deep Stratospheric Intrusions and the Tibetan Plateau Topographic Forcing

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Given our poor understanding on mechanisms of stratospheric intrusions (SI) upon near‐surface ozone (O3) surges, predicting the SI‐induced O3 pollution pose inherent difficulties. Taking a wintertime O3 surge episode over the Sichuan Basin (SCB) as an example, we find SI contribute 47.8% to near‐surface O3 levels and reveal the underlying ...
