Investigation of the limonene photooxidation by OH at different NO concentrations in the atmospheric simulation chamber SAPHIR (Simulation of Atmospheric PHotochemistry In a large Reaction Chamber) [PDF]

Atmospheric Chemistry and Physics, 2022
The oxidation of limonene by the hydroxyl (OH) radical and ozone (O3) was investigated in the atmospheric simulation chamber SAPHIR (Simulation of Atmospheric PHotochemistry In a large Reaction Chamber) in experiments performed at different nitric oxide (

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

Weather 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 ...

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

, 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 ...

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

Atmospheric 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

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

Serbian 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.

Tropospheric amplification of stratosphere–troposphere coupling

Quarterly Journal of the Royal Meteorological Society
Abstract During northern winter the stratospheric polar vortex is highly variable — even breaking down completely during sudden stratospheric warmings. The strength of the stratospheric polar vortex is observed to be coupled to surface weather, primarily through swings in the phase of the Northern Annular Mode — which is nearly ...

Observational evidence reveals the significance of nocturnal chemistry in seasonal secondary organic aerosol formation

npj Climate and Atmospheric Science
Oxidized Organic Aerosol (OOA), a major component of fine atmospheric particles, impacts climate and human health. Previous experiments and atmospheric models emphasize the importance of nocturnal OOA formation from NO3· oxidation of biogenic VOCs.
