Abstract. Within the framework of AeroCom (Aerosol Comparisons between Observations and Models) initiative, state-of-the-art modelling aerosol optical properties is assessed from 14 global models participating in phase III control experiment (AP3). The are similar to CMIP6/AerChemMIP Earth System Models (ESMs) provide a robust multi-model ensemble. Inter-model spread species lifetimes emissions appears be that mass extinction coefficients (MECs), suggesting depth (AOD) uncertainties...
Abstract. Aerosol particles are essential constituents of the Earth's atmosphere, impacting earth radiation balance directly by scattering and absorbing solar radiation, indirectly acting as cloud condensation nuclei. In contrast to most greenhouse gases, aerosol have short atmospheric residence times, resulting in a highly heterogeneous distribution space time. There is clear need document this variability at regional scale through observations involving, particular, situ near-surface...
Abstract. This study presents a multiparameter analysis of aerosol trends over the last 2 decades at regional and global scales. Regional time series have been computed for set nine optical, chemical-composition mass properties by using observations from several ground-based networks. From these derived different regions world. Most related to loading exhibit negative trends, both surface in total atmospheric column. Significant decreases optical depth (AOD) are found Europe, North America,...
Abstract. Aerosol-induced absorption of shortwave radiation can modify the climate through local atmospheric heating, which affects lapse rates, precipitation, and cloud formation. Presently, total amount aerosol is poorly constrained, main absorbing species (black carbon (BC), organic aerosols (OA), mineral dust) are diversely quantified in global models. As part third phase Aerosol Comparisons between Observations Models (AeroCom) intercomparison initiative (AeroCom III), we here document...
This paper encompasses an assessment of air pollution trends in rural environments Europe over the 2000–2019 period, benefiting from extensive long-term observational data EMEP monitoring network and MSC-W model computations. The pollutant concentrations align with decreasing emission patterns observed throughout Europe. Annual average sulfur dioxide, particulate sulfate, wet deposition have shown consistent declines 3-4% annually since 2000. Similarly, oxidized nitrogen species markedly...
Abstract. Spatial and temporal profiles of chlorine dioxide (OClO), bromine monoxide (BrO) sulfur (SO2) the volcanic plume at Mt. Etna, Italy, were investigated in September 2012 using Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS). OClO was detected 119 individual measurements covering ages up to 6 min. BrO could be 452 spectra 23 min downwind. The retrieved slant column densities (SCDs) reached maximum values 2.0 × 1014 molecules cm-2 (OClO) 1.1 1015 (BrO). Mean mixing...
Abstract. Accurate gas velocity measurements in emission plumes are highly desirable for various atmospheric remote sensing applications. The imaging technique of UV SO2 cameras is commonly used to monitor emissions from volcanoes and anthropogenic sources (e.g. power plants, ships). camera systems capture the at high spatial temporal resolution. This allows velocities plume be retrieved directly images. latter can measured a pixel level using optical flow (OF) algorithms. particularly...
Abstract Mount Cleveland is one of Alaska's most active volcanoes, yet little known about the magmatic system driving persistent and dynamic volcanic activity. Volcanic gas melt inclusion (MI) data from 2016 were combined to investigate shallow processes. SO 2 emission rates between 166 324 t/day H O/SO was 600 ± 53, whereas CO S below detection. Olivine‐, clinopyroxene‐, plagioclase‐hosted MIs have up 3.8 wt.% O, 514 ppm , 2,320 S. Equilibration depths, based on MI O contents, suggest that...
Ultraviolet (UV) SO2 cameras have become a common tool to measure and monitor emission rates, mostly from volcanoes but also anthropogenic sources (e.g., power plants or ships). Over the past decade, analysis of UV camera data has seen many improvements. As result, for required steps, several alternatives exist today cell vs. DOAS based calibration; optical flow cross-correlation gas-velocity retrieval). This inspired development Pyplis (Python plume imaging software), an open-source...
Abstract. Within the framework of AeroCom (Aerosol Comparisons between Observations and Models) initiative, present day modelling aerosol optical properties has been assessed using simulated data representative for year 2010, from 14 global models participating in Phase III Control experiment. The model versions are close or equal to those used CMIP6 AerChemMIP inform also on bias state art ESMs. Modelled column depths (total, fine coarse mode AOD) Angstrom Exponents (AE) were compared both...
