Für unser Leben haben sie eine immense Bedeutung. Wolken sind zentraler Bestandteil des globalen Wasserkreislaufs, in ihnen werden die Regentropfen und Eiskristalle gebildet, die am Ende große Teile des aus den Ozeanen verdunsteten Wassers auf die Kontinente bringen, wo es uns für den Nahrungsmittelanbau und als Trinkwasser zu Verfügung steht. Der Niederschlagsvorgang zählt zu den Wetterereignissen. Wolken, die im globalen Mittel mehr als 70% der Erde bedecken, sind auch ein ungemein wichtiger Klimafaktor. Die im Klimasystem alles antreibende Sonneneinstrahlung wie auch die ausfallende Wärmestrahlung müssen auf ihrem Weg die Atmosphäre und damit häufig Wolken passieren. Dabei kommt es zur Streuung und Absorption, beides im Ausmaß abhängig von der Partikelart, -anzahl und Größenverteilung. Tiefe Wasserwolken haben einen kühlenden Effekt auf das Klima, hohe Eiswolken tendieren dazu das Klima zu erwärmen, da sie einen eigenen Treibhauseffekt aufweisen. Derzeit überwiegt der kühlende Einfluss der Wolkenpopulation, das kann sich aber mit dem Klimawandel verändern. In Klimamodellen gehören Wolken und ihre Wechselwirkung mit Partikeln in der Atmosphäre zu den größten Unsicherheitsfaktoren. Der Umwelteinfluss von Wolken ist hauptsächlich durch chemische Umwandlungsprozesse von Schadgasen in Wassertröpfchen und an Eiskristallen geben. Die in Wolken entstehenden Niederschläge bringen auch Anteile von Schadgasen und Feinstaubpartikeln zurück zum Erdboden, ein Vorgang der nasse Deposition genannt wird. Dadurch wird die Atmosphäre gereinigt. Der Vortrag wird die unterschiedlichen Wolkenarten vorstellen und deren Bildung auf verständliche Weise beschreiben. Die Niederschlagsbildung und die Prozesse, die die Klimawirksamkeit und den Umwelteinfluss ausmachen werden kurz skizziert. Abschließend werden moderne Wolkenbeobachtungsinstrumente - am Boden, auf Flugzeugen und auf Satelliten - anschaulich vorgestellt.}, note = {Online available at: \url{} (DOI).

Besides these GHGs, there are many other gases and aerosolos in the atmosphere, which have a much more direct and immediate impact on human health: air pollutants. The World Health Organization (WHO) considers air pollution to be the world's single largest environmental health threat, accounting for approximately 7 million deaths worldwide every year. That's why in this talk we want to speak about how the problem of air pollution can be understood and predicted using HPC pollution modeling and its application based on general concepts and our own research. We are Dr. Johannes Bieser and Dr. Martin Ramacher, both working at the Helmholtz Zentrum Hereon in the field of numerical pollution modelling. While Dr. Bieser wrote his Dissertation on emission modelling and its application, Dr. Ramacher wrote his Dissertation on pollutant transport and exposure modelling. In our talk on numerical air quality modelling systems, we want to introduce basic principles and share our personal knowledge in the field of numerical pollution modelling, covering the entire pathway from emissions, transport, transformation and human exposure. Each of these steps relies heavily on large amounts of data from many different sources - satellite data, activity and meta data, measurements and many more - and skills in computer science. By default, environmental scientists are often not trained in computer science and high performance computing which implies a challenge of its own (and allows Nerds like us to excel). Our talk will be enriched with practical, technical and partially political examples to demonstrate the difficulties scientist face during their quest to improve air quality for everyone: from TB of wasted data due to historically grown data formats to counterproductive policy decisions to „improve“ air quality. We’ve seen it all and after participating in the CCC for many years now, we decided to draw attention to some state-of-the science approaches for solving one of the world’s single largest environmental health threats: „air pollution“.}, note = {Online available at: \url{} (DOI).

Consequently, in this study we developed a method for regional exposure estimates by taking into account population activity, as well as infiltration of air pollutants to indoor environments. Therefore, we applied the time-microenvironment-activity concept in combination with different datasets for spatial and temporal distribution of the European population. The applied datasets are mainly JRC ENACT datasets for day and night time populations for the whole of Europe, Copernicus Monitoring Service land use information, the GHSL data package 2022 and Eurostat population statistics. The result is a framework that allows for the whole of Europe to create grids of population activity in different microenvironments with a spatial resolution of 1x1 km2 and a temporal resolution of 1 hour. Additionally, each microenvironment is assigned to seasonal dependent literature based outdoor to indoor infilatration factors. The resulting dynamic population grids can be applied to mapped air pollutant concentrations derived with any air quality model, for any European domain or period. Finally, we applied (1) the developed dynamic exposure model and (2) a static residential addresses dataset to air pollutant concentrations to regions in Europe and compared the resulting exposure estimates. The results show differences in population exposure to PM2.5, NO2 and O3. In general, the results indicate that the exposure derived with established approaches is lower compared to the developed approach, which means that the adverse health effects might currently be underestimated for the European population.}, note = {Online available at: \url{} (DOI).

In coastal Mediterranean cities, shipping activities are an important contributor to emissions of fine particulate matter (PM2.5) within the urban area. In addition to primary particles emitted in ship exhaust, secondary organic aerosols (SOA) may form in ship plumes through chemical oxidation of volatile organic compounds (VOC) and through condensation of intermediate volatile or semi-volatile organic gases. Shipping also emerges as a major source of ultrafine particles below 100 nm diameter in coastal cities. Ultrafine particles have been estimated to significantly affect human mortality in coastal areas. While a large number of studies investigated the effect of ship-related PM2.5 in coastal areas, currently only few studies deal with the effect of ship emissions on SOA concentrations and number concentrations of ultrafine particles in harbour cities.In this study, we investigate the effect of ship emissions on SOA concentrations and number concentrations of UFP in the harbour city Marseille in southern France, which is an important hub of ferry and cruise ship traffic in the Mediterranean Sea. For city-scale simulations of Marseille, the urban chemistry transport model EPISODE-CityChem (https://doi.org/10.5281/zenodo.1116173) was applied in a coupled setup with the regional-scale Community Multiscale Air Quality Modelling System (CMAQ). EPISODE-CityChem combines a 3-D Eulerian grid model with sub-grid Gaussian plume models and solves the photochemistry of multiple reactive pollutants, including the chemistry of 12 different VOC. New developments in EPISODE-CityChem include the P8P+2 scheme for calculating particle number (PN) concentration and particle number size distribution (PNSD) and the SOA module of the aerosol model MAFOR v2.0 (https://github.com/mafor2/mafor). The STEAM-3 emission inventory for the local shipping in and around the port of Marseille consists of hourly emissions of major pollutants, VOC and particle numbers from ships on 250 m grid resolution. Hourly model output of EPISODE-CityChem for July 2020 was compared to measurements at monitoring stations in Marseille operated by AtmoSud and campaign data recorded at La Major, a site in proximity of the port.Our results show that the potential impact from local shipping to the monthly mean concentration in the urban area of Marseille is only up to 3% for PM2.5, whereas it is up to 42% for total PN. The abundance of ship-related semi-volatile organic vapours is high in the areas of SOA formation, which indicates that volatile organics are mainly in the gas phase because available pre-existing particle surfaces and high ambient temperatures limit their condensation. Ship plumes at La Major were detected based on the difference of total PN concentration between the reference run and a model run excluding ship emissions. The maximum of the modelled and the observed PNSD notably corresponded to the typical size distribution maximum of ship exhaust particles. Total PN should be considered as a more suitable metric for monitoring ship emission impact than PM2.5 because it allows for a better discrimination of ship plumes from the background pollution.}, note = {Online available at: \url{https://doi.org/10.5194/egusphere-egu23-2239} (DOI).

They are the most used pesticides worldwide. Their extensive use has led to great social concerns regarding their environmental fate and toxicity to non-target organisms and to human health. Consequently, glyphosate is at risk of being banned in the EU and 3 NNs (imidacloprid, clothianidin and thiamethoxam) have recently been permanently banned for outdoor applications. Nevertheless, their use is still permitted in China. Moreover, NNs have been incorporated in the watch list of substances for the EU monitoring program in surface waters (2015/495/EU) due to possible threats to aquatic organisms. Therefore, these compounds are emerging environmental contaminants of concern.,This study investigates the temporal and spatial occurrence of 7 NNs, as well as other insecticides (fipronil, imidaclothiz, cycloxaprid and sulfoxaflor), the herbicide glyphosate and several of their transformation products in the Chinese Bohai Sea and its surrounding rivers. Water samples were collected in the summer and fall of 2018 from 36 rivers and 47 stations in the Bohai Sea. All samples were immediately stored at -20°C until analysis. All samples were extracted by solid-phase extraction (1L water sample was used for the insecticides, whereas 20 mL water sample was used for glyphosate and its main metabolite AMPA (aminomethylphosphonic acid)), eluted with methanol and further enriched by evaporation. For glyphosate and AMPA, the water samples were first derivatized with FMOC-Cl (9-Fluorenylmethoxycarbonyl chloride). All samples were analyzed by HPLC-MS/MS.,The results show that, from the 18 compounds analyzed, 15 were detected in river samples and 12 in seawater samples. Acetamiprid was detected in all river- and seawater samples. Much higher concentrations were observed in the rivers (
