The Atmosphere and Climate Competence Center (ACCC) \u2013 Finnish Atmospheric Sciences Network (FASN) Conference (https:\/\/en.ilmatieteenlaitos.fi\/accc-fasn2024<\/a>) took place onsite during 11-12 Nov 2024 (Helsinki, Finland). It has been jointly organized by the University of Helsinki and the Finnish Meteorological Institute. More than 200 participants attended the conference.<\/p>\n

On Monday, 11 Nov 2024, the conference included two oral sessions and the poster session on evening. The first session on \u201cQuantifying and activating the potential of land-based climate change mitigation<\/em>\u201d took place in the morning, and started from a plenary talk on \u201cAtmosphere-biosphere feedbacks: matching puzzle pieces<\/em>\u201d, followed by presentations from contributing speakers about: barley monoculture vs. barley with undersown species: impact of diversity on green-house gases (GHG) exchange in Finland; effect of extreme weather on peatland GHG exchange in future climate using JSBACH-HIMMELI ecosystem model; new particle formation (NPF) in Milan: an investigation about the role of meteorological conditions and urban pollution; review of the European Union Carbon Removals and Carbon Farming Certification (CRCF) Regulation; quantifying uncertainty in carbon dioxide removal with Gaussian process emulators and Markov Chain Monte Carlo; optimizing forest carbon sinks. The session continued with a plenary talk on \u201cClimate change attribution of extremes and their impacts in Finland<\/em>\u201d, followed by presentations about role of bark in tree survival under drought stress; ecological restoration of low-productive peatlands drained for forestry; effect of urbanization of the Chinese gigacity on the water and energy balances; severe haze episodes in Beijing may have origins as far as 2000 km west; new guidance documents on advanced air quality parameters by RI-URBANS.<\/p>\n

The second session took place with presentations about characterization of water-soluble inorganic ions and carbo-naceous aerosols in the urban atmosphere in Amman, Jordan; prediction of droplet size distribution ruptured from lung airways using numerical simulations; satellite observations to support air quality monitoring in East Africa; potential of satellite observations to advance our understanding of atmospheric methane in the Arctic. The poster session (during 16-18 pm) had more than 80 posters covering different topics of the conference, and it followed by the conference dinner.<\/p>\n

On Tuesday, 12 Nov 2024, the third session on \u201cClimate change impacts and adaptation<\/em>\u201d took place in the morning, starting from a plenary talk on \u201cWhat do we know, and do not know, about the fate of permafrost nitrogen following thaw?<\/em>\u201d, and followed by presentations about transformative climate change education in art-science collaboration; targeted metagenomics using probe capture detect a larger diversity of nitrogen and methane cycling genes than traditional metagenomics \u2013 do nitrogen cycling microbes play a role in plant tissues?; evaluating and optimising integration between climate and air pollution policies: the ClimAirPathways approach; effects of a long-term water level drawdown on phototrophic communities and photosynthesis in boreal peatlands; role of the European Scientific Advisory Board on climate change; xylem conduits and inter-conduit pits of Scots pine, Norway spruce and Silver birch scale in a coordinated way with distance from the treetop.<\/p>\n

The fourth session on \u201cQuantifying the air quality \u2013 climate interactions and their impacts<\/em>\u201d started with a plenary talk on \u201cEmissions beyond greenhouse gases: exploring how they shape our one atmosphere<\/em>\u201d, followed by presentations about satellites capture socioeconomic disruptions during the 2022 full-scale war in Ukraine; Multi-Pressure Chemical Ionization Mass Spectrometry for the analysis of complex gas mixtures; Wintertime brown carbon characterization: understanding chemical composition and light absorption in residential and traffic areas; Nuclear observations to improve climate research and GHG emission estimates \u2013 NuClim; Linking sulphur dioxide, sulfuric acid, clusters, and small particles: implications for future particle formation events; Could contrail properties change when commercial aircraft use Sustainable Aviation Fuel instead of standard JET A-1 fuel?; Deposition ice nucleation on silica particles via an adsorption-freezing mechanism; Estimating global accumulation-mode particle number concentrations with machine learning and reanalysis data; new atmospheric measurement site in northern Botswana; effect of noise barriers on air quality using PALM model; quantifying the contributions of new particle formation and traffic emissions on urban ultrafine particle concentrations; examining the role of sedimentation in modulating ice nucleation pathways in cirrus clouds; Accretion products for probing RO2 chemistry; preliminary summary of Urbaani ilmanlaatu 2.0 project; Cluster Ion Counter: a tool to investigate local new particle formation and condensation sink.<\/p>\n

During the conference the outcomes of the Horizon 2020 research projects RI-URBANS (https:\/\/riurbans.eu<\/a>) and CRiceS (https:\/\/www.crices-h2020.eu<\/a>) as well as the Erasmus+ educational projects ClimEd (http:\/\/climed.network<\/a>) and CLUVEX (https:\/\/www.atm.helsinki.fi\/cluvex<\/a>) were also presented, and where the PEEX is actively involved also with dissemination of results.<\/p>\n
