Identification of high-wind features within extratropical cyclones using a probabilistic random forest – Part 2: Climatology over Europe [PDF]

open access: yesWeather and Climate Dynamics, 2023
Strong winds associated with extratropical cyclones are one of the most dangerous natural hazards in Europe. These high winds are mostly associated with five mesoscale features: the warm (conveyor belt) jet (WJ); the cold (conveyor belt) jet (CJ); cold ...

Variations in Ozone Concentration over the Mid-Latitude Region Revealed by Ozonesonde Observations in Pohang, South Korea

open access: yesAtmosphere, 2020
Ozone absorbs harmful UV rays at high elevations but acts as a pollutant gas in the lower atmosphere. It is necessary to monitor both the vertical profile and the total column ozone.

The underestimated role of stratosphere-to-troposphere transport on tropospheric ozone [PDF]

open access: yes, 2018
Abstract. The atmospheric composition is strongly influenced by changing atmospheric dynamics, in potential relation to climate change. A prominent example is the doubling of the stratospheric ozone component at the summit station Zugspitze (2962 m a.s.l., Garmisch-Partenkirchen, Germany) between the mid-seventies and 2005, roughly from 11 ppb to 23 ...

The tropospheric scintillation prediction of earth-to-satellite link for Bangladeshi climatic condition [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2015
The performance of earth-to-satellite link largely depends on various environmental factors like rain, fog, cloud, and atmospheric effects like ionospheric and tropospheric scintillation.

Measurement report: Comprehensive seasonal study of the composition and sources of submicron aerosol during the JULIAC campaign in Germany [PDF]

open access: yesAtmospheric Chemistry and Physics
The seasonal variations of aerosol sources and their atmospheric evolution are investigated using observations from the year-long JULIAC (Jülich Atmospheric Chemistry Project) campaign (January–November 2019) in Jülich, Germany.

The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability

open access: yesEnvironmental Research Letters, 2020
Tropospheric and stratospheric tropical temperature trends in recent decades have been notoriously hard to simulate using climate models, particularly in the upper troposphere.

The potential of drone observations to improve air quality predictions by 4D-Var [PDF]

open access: yesAtmospheric Chemistry and Physics
Vertical profiles of atmospheric pollutants, acquired by uncrewed aerial vehicles (UAVs, known as drones), represent a new type of observation that can help to fill the existing observation gap in the planetary boundary layer (PBL). This article presents
