  The interannual variability of snow cover in alpine areas is increasing, which may affect the tightly coupled cycles of carbon and water through snow–vegetation–atmosphere interactions across a range of spatio-temporal scales. To explore the role of snow cover for the land–atmosphere exchange of CO2 and water vapor in alpine tundra ecosystems, we combined 3 years (2019–2021) of continuous eddy covariance flux measurements of the net ecosystem exchange of CO2 (NEE) and evapotranspiration (ET) from the Finse site in alpine Norway (1210 m a.s.l.) with a ground-based ecosystem-type classification and satellite imagery from Sentinel-2, Landsat 8, and MODIS. While the snow conditions in 2019 and 2021 can be described as site typical, 2020 features an extreme snow accumulation associated with a strong negative phase of the Scandinavian pattern of the synoptic atmospheric circulation during spring. This extreme snow accumulation caused a 1-month delay in melt-out date, which falls in the 92nd percentile in the distribution of yearly melt-out dates in the period 2001–2021. The melt-out dates follow a consistent fine-scale spatial relationship with ecosystem types across years. Mountain and lichen heathlands melt out more heterogeneously than fens and flood plains, while late snowbeds melt out up to 1 month later than the other ecosystem types. While the summertime average normalized difference vegetation index (NDVI) was reduced considerably during the extreme-snow year 2020, it reached the same maximum as in the other years for all but one of the ecosystem types (late snowbeds), indicating that the delayed onset of vegetation growth is compensated to the same maximum productivity. Eddy covariance estimates of NEE and ET are gap-filled separately for two wind sectors using a random forest regression model to account for complex and nonlinear ecohydrological interactions. While the two wind sectors differ markedly in vegetation composition and flux magnitudes, their flux response is controlled by the same drivers as estimated by the predictor importance of the random forest model, as well as by the high correlation of flux magnitudes (correlation coefficient r=0.92 for NEE and r=0.89 for ET) between both areas. The 1-month delay of the start of the snow-free season in 2020 reduced the total annual ET by 50 % compared to 2019 and 2021 and reduced the growing-season carbon assimilation to turn the ecosystem from a moderate annual carbon sink (−31 to −6 gC m−2 yr−1) to a source (34 to 20 gC m−2 yr−1). These results underpin the strong dependence of ecosystem structure and functioning on snow dynamics, whose anomalies can result in important ecological extreme events for alpine ecosystems.

  Dynamic Global Vegetation Models (DGVMs) provide a state-of-the-art process-based approach to study the complex interplay between vegetation and its physical environment. For example, they help to predict how terrestrial plants interact with climate, soils, disturbance and competition for resources. We argue that there is untapped potential for the use of DGVMs in ecological and ecophysiological research. One fundamental barrier to realize this potential is that many researchers with relevant expertize (ecology, plant physiology, soil science, etc.) lack access to the technical resources or awareness of the research potential of DGVMs. Here we present the Land Sites Platform (LSP): new software that facilitates single-site simulations with the Functionally Assembled Terrestrial Ecosystem Simulator, an advanced DGVM coupled with the Community Land Model. The LSP includes a Graphical User Interface and an Application Programming Interface, which improve the user experience and lower the technical thresholds for installing these model architectures and setting up model experiments. The software is distributed via version-controlled containers; researchers and students can run simulations directly on their personal computers or servers, with relatively low hardware requirements, and on different operating systems. Version 1.0 of the LSP supports site-level simulations. We provide input data for 20 established geo-ecological observation sites in Norway and workflows to add generic sites from public global datasets. The LSP makes standard model experiments with default data easily achievable (e.g., for educational or introductory purposes) while retaining flexibility for more advanced scientific uses. We further provide tools to visualize the model input and output, including simple examples to relate predictions to local observations. The LSP improves access to land surface and DGVM modelling as a building block of community cyberinfrastructure that may inspire new avenues for mechanistic ecosystem research across disciplines.

  Long photoperiods characteristic of summers at high latitudes can increase ozone-induced foliar injury in subterranean clover (Trifolium subterraneum) This study compared the effects of long photoperiods on ozone injury in red and white clover cultivars adapted to shorter or longer daylengths of southern or northern Fennoscandia. Plants were exposed to 70 ppb ozone for six hours during the daytime for three consecutive days. Simultaneously, the daylength in the growth rooms was altered to long-day (10 h light; 14 h dim light) and short-day (10 h light; 14 h darkness) conditions. Thermal imaging showed that ozone disrupted leaf temperature and stomatal function, particularly in sensitive species, in which leaf temperature deviations persisted for several days after ozone exposure. Longday conditions increased visible foliar injury (30%–70%), characterized by chlorotic and necrotic areas, relative to short day conditions in all species and cultivars independently of the photoperiod in the region they were adapted to.

  Although roots are normally hidden in soil, they may inadvertently be exposed to low light levels in experiments or in natural conditions through cracks or light transmittance through the soil. Light has been implicated in root morphogenesis. Thus, effects of low light conditions on lentil (Lens culinaris L. cv. Verte du Puy) root morphology and root pigmentation were studied. Lentil seedlings were grown in peat or transparent, nutrient-fortified agar at a 12-h light (PAR 240 μmol·m−2·s−1), 12-h dark cycle. Roots were exposed to low levels (∼1–10 μmol·m−2·s−1) of broadband white light, either directly or indirectly by aboveground light penetrating the growth medium. Control roots were grown in darkness. In situ spectroscopy was used to measure transmittance and reflectance spectra of intact root tissue by mounting the upper part of the primary root directly in a spectrophotometer equipped with an integrating sphere attachment. The transmittance and reflectance spectra were used to calculate the in situ root absorbance spectrum. Absorbance bands were found in the regions 480–500 nm and 650–680 nm, possibly due to low levels of root-localised carotenoids and chlorophylls, respectively. Low light levels (∼1–10 μmol·m−2·s−1) transmitted through the growth medium significantly increased root pigment concentration and root biomass, and altered root morphology by enhancing lateral root formation and inhibiting root elongation relative to roots grown in complete darkness. The light-induced changes in root morphogenesis and pigmentation appear to be primarily due to upper root light perception.

  Soil surrounding a growing root must be displaced to accommodate the increased root volume. To ease soil penetration, root caps produce border cells and mucilage that lubricate the root surface, decreasing friction at the root-soil interface. Rhizosphere deformations caused by roots with or without a functional root cap were compared to determine the effects of the root cap on sand displacement and penetration. Intact (KYS wild type) and decapped (agt1(dec) mutant) primary maize roots were grown in observation chambers filled with sand. Non-destructive time-lapse micro-imaging combined with particle image velocimetry was used to visualize and quantify sand displacements as small as 0.5 mu m caused by growing roots. Decapped (agt1(dec)) roots displayed typical responses of mechanically impeded roots at sand densities that did not affect intact KYS roots. Sand displacement decreased exponentially with distance from the root and extended four to eight root radii into the sand. The calculated mean sand density increase and the compressed sand area were doubled by decapping. Maximum density often occurred in front of the apex of decapped roots whereas it occurred along the sides of intact roots. Periodic variation in sand deformation was observed, probably associated with root circumnutation, which may also facilitate soil penetration. Sand particles moved alongside KYS roots more easily than they did alongside agt1(dec) roots. A functional exuding cap was therefore essential for efficient rhizosphere deformation and penetration by roots. Manipulating root tip, and specifically root cap, properties is a possible target for improving root penetration in hard soil.

  Although leaves are the primary sites of tropospheric ozone exposure, it has been postulated that ozone may cause greater and earlier disruption of below-ground growth with long-term consequences for productivity. As plant roots are hidden in soil, the time-course of ozone-induced below-ground changes remains poorly characterised. In this study, the in vivo root development before, during and after short-term ozone exposure of individual subterranean clover seedling shoots (Trifolium subterraneum L.) was studied non-destructively using a new experimental growth and exposure system. Plants were grown individually in thin root growth chambers, where the entire root system could be observed non-invasively for weeks. Seedlings were exposed individually in separate exposure cuvettes to either charcoal filtered air (n=3, similar to 1-3 ppb ozone) or charcoal filtered air supplemented with ozone giving a concentration of 75 10 ppb ozone (n=3) for 8 h during daytime for five consecutive days (AOT40 index 1400 ppb h) starting eleven days after sowing. 171 High-resolution digital images of the roots were captured every one-four days and were analysed to determine root length and root tip formation. Altered root growth occurred within the first week after exposure and persisted for three weeks. Root tip formation and elongation rates were reduced by 35-40%. Doubling of the number of root tips was delayed by one week. Roots of exposed plants were therefore shorter and less branched. Above-ground changes were apparent about one week after below-ground changes. The leaf development rate was reduced by about 25%, but the number of flower stems at harvest was unaffected. Ratios between below and above-ground growth were significantly reduced by similar to 60% the first week after exposure and remained lower for up to three weeks suggesting reduced carbon allocation to root growth. Nevertheless, biomass and biomass ratios at harvest five weeks after exposure were not significantly altered, indicating that traditional destructive sampling once, at harvest, would not have revealed any of the early below-ground changes observed in this study. Thus, ozone caused substantial changes to root architecture that may ultimately affect the root's function and thereby the plant's overall health and ability to cope with stress.

  Previous experiments have shown that several European clovers may develop more visible injuries due to ozone when the night is not dark. At high latitudes, the summer nights are bright, giving the background for the question whether plants adapted to midnight sun also have this response of being more easily injured by ozone when the night is not dark. The plants included in the present experiment are expected to be adapted to light exposure during night, since there is midnight sun from the time they melt out of the snow cover in spring until the end of July, in the sites where they were collected. This constitutes about 50 % of the growing season for grassland species in these areas. Cuttings of two genotypes of white clover (Trifolium repens) collected in two sites in subarctic Norway were cultivated under controlled environment conditions. Using a factorial design, the plants were exposed to two different night-time light conditions and two different ozone exposure levels. We studied the development of visible injuries, foliar chlorophyll concentrations and N concentration as signs of premature senescence due to ozone.

  Here we assess the importance of characterization of key meteorological variables and air pollution profiles on the modeled susceptibility of subarctic vegetation to ozone. Changes in climate (e.g. temperature, water availability) will manifest in both direct and indirect effects influencing the species' sensitivity to air pollution. A likely increase in frequency of persistent heatwaves in the future, will inflict heat related stress while generating favorable conditions for the formation of ambient air ozone, e.g. due to wildfires. We have monitored ambient air ozone concentrations at the Norwegian Institute of Bioeconomy Research (NIBIO) Environment Centre Svanhovd in Northern Norway in the vegetation period 2018/19. Due to data acquisition problems, ozone concentrations for two weeks in July 2018 were missing from our record. We present a reconstruction based on probability density function with respect to the Swedish and Finnish atmospheric monitoring sites and compare with available surface ozone products for the region. Over all, ozone concentrations did not differ significantly between the two years. While temperatures and global irradiance diverged substantially from the multi annual mean precipitation varied only to some extend. We investigate the difference in uptake of ozone using the DO3SE model, for typical vegetation at the location. We find that bespoke parameterization for subarctic vegetation is essential for an accurate estimation of Phototoxic Ozone Dose (POD) and an assessment of damage risk. Accurate estimates of the start and length of growing season are also crucial. We find that temperature and its derivative vapor pressure deficit are likely the most important climate variables while the variability of ozone concentration within climatologically reasonable limits plays a minor role. The use of subarctic parameterization suggests an improvement in risk assessment as POD values are increased in 2018; corroborated by evidence of visible injury in the Svanhovd ozone garden.

  The Arctic biosphere is subject to comprehensive changes induced by climate change. The highly specialized subartic vegetation will be challenged by both, changing environmental conditions as well as further interference through human activity. Permission of exploitation of natural resources in the Artic is likely to increase the levels of air pollutants which are precursors to ozone. n the course of our project (OzoNorClim: The Double Punch), we had an ozone monitor installed at the Norwegian Institute for Bioeconomic Research (NIBIO) Svanhovd Research Station operated by the Norwegian Institute for Air Research (NILU). In 2018, a long-lasting heatwave accompanied by extensive forest fires across Europe and Scandinavia enhanced surface ozone concentrations by about 2 ppt above the climatological mean in Northern Scandinavia. Ozone sensitive glover species in the ozone garden at Svanhovd showed clear signs of ozone damage in 2018 but not in 2019. We study these two years as example for probable future scenarios in which both heat stress and ozone stress affect vegetation negatively. We look at the corresponding surface ozone concentrations, accumulated ozone dose, and implications on natural and semi-natural vegetation especially in the Pasvik valley in Northern Norway, put these in a larger regional context, and give an outlook on further modelling work.

  Ozon ist eines der wichtigsten Spurengasen in der Atmosphäre. Während es uns in Form der Ozonschicht in der Stratosphäre vor schädlicher, kurzwelliger Strahlung schützt, zählt es in der planetaren Grenzschicht zu den überaus schädlichen Reizgasen. Eine Aufnahme einer Dosis von 50 ppm über die Dauer von 30 min gilt für den Menschen als tödlich. Pflanzen nehmen Ozon durch ihre Stoma auf, wo dieses zur Zerstörung von Zellen beiträgt, die der Photosynthese dienen, und letztlich Wachstum und Ertrag reduziert. Die empfindlichen Ökosysteme im Norden Skandinaviens erfahren bereits durch den Klimawandel einen erhöhten Stress. Sollte das Polarmeer dauerhaft eisfrei werden, so würde sich der Schiffsverkehr und damit die Menge der Ozonvorläufersubstanzen drastisch erhöhen. Insbesondere während des Polarsommers ist eine nächtliche Reparatur der entstandenen Ozonschäden gehindert. Wir präsentieren hier einen Überblick über die schädlichen Auswirkungen von Ozon auf Vegetation und erste Studien zu der Entwicklung von Ozonkonzentrationen in Nordskandinavien. Dabei greifen wir sowohl auf Langzeitmessungen als auch Modellsimulationen zurück.

  Norge har et eksisterende overvåkingsnettverk for å måle effekter av luftforurensninger som forsuring, overgjødsling og ozoneksponering i økosystemer. Ved eventuell implementering av nytt NEC‐direktiv «takdirektiv» (2016/2284/EU) må Norge rapportere inn overvåkingsnettverk og resultater fra overvåking av effekter av luftforurensninger i økosystemer. I denne rapporten er dagens overvåkingsnettverk vurdert med hensyn til de krav som stilles i nytt NEC‐direktiv. Resultater viste at for innsjøer og elver er dagens overvåkingsnettverk relatert til forsuring tilfredsstillende. For overgjødsling av skog, skogsjord og terrestrisk natur er det behov for oppgraderinger av overvåkingsnettverket. I forhold til ozonskader i vegetasjon er det behov for oppgraderinger av dagens overvåkingsnettverk. Det vil påløpe kostnader for opprettelse av nye overvåkingsstasjoner og oppgraderinger av dagens overvåkingsnettverk. Estimerte kostnader for å dekke mangler i eksisterende overvåkingsnettverk er angitt i rapporten.
