<p>The Environmental Research Station Schneefernerhaus (UFS) is Germany’s highest research station, located at an altitude of 2650 m. For over 20 years, many different institutions have been working here on a variety of permanent studies on an inter- and trans-disciplinary basis. Eight key scientific activities were assigned in 2007. These are:</p><ul><li>Satellite-based observations and early detection</li> <li>Regional climate and atmosphere</li> <li>Cosmic radiation and radioactivity</li> <li>Hydrology</li> <li>Environmental and high-altitude medicine</li> <li>Global Atmosphere Watch (GAW)</li> <li>Biosphere and Geosphere</li> <li>Cloud dynamics</li> </ul><p>Beyond these permanent research activities, around 80 temporary projects have been conducted with over 13 international partners. Over 30 projects are currently running at the UFS. The ‘size’ of the projects varies from small research groups and very short-term studies, to large research consortiums and long-term projects. The UFS is, furthermore, a partner in a number of international networks of (mountain) observatories, such as the Global Atmosphere Watch program of the WMO. International exchange is therefore guaranteed.</p><p>The operating company of the UFS makes the high quality of research possible. It takes care of the needs of the researchers, such as logistics, data transfer and exchange, and outreach. The UFS also serves as a meeting and educational center for research teams, operators of other stations and early- career scientists. The UFS is easily accessible all year round: a train line runs up the mountain, directly into the UFS building and allows the transportation of heavy material and devices. A well-equipped workshop allows the in-situ repair of instruments.</p><p>Beside some general information about the UFS, the presentation will highlight some recent projects in which the UFS has been involved. It will also show how to use the UFS for your own research ideas.</p>

<p>Education is key in order to create a generation that thinks and acts sustainable and that considers nature as one of the most important good.Within the three years Interreg Project ‘KlimaAlps’ (www.klimaalps.eu) – making climate change visible - one major task is the establishment of a training for educators, to become a certified ‘Climate-Pedagogue’ for the alpine region. The ‘Climate-Pedagogue’-training contains background information of climate change in the Alps and a variety of innovative educational tools and methods. It covers aspects of the high mountain areas, rivers and lakes, human beings, agriculture as well as moors.  The project is managed by the ‘Energiewende Oberland’; five additional partners from Austria and Bavaria are responsible for e. g. a high quality of the taught scientific information (Environmental Research Station Schneefernerhaus), the didactical input (University of Innsbruck, Department of Geography), the outreach activities and the implementation (Naturpark Karwendel, Klimabündnis Oberösterreich, Landratsamt Garmisch-Partenkirchen). During the last one and half years, the concept for the ‘Climate-Pedagogue’- training was worked out in cooperation with other environmental facilities and in March 2021 the first lectures of a pilot run with over 30 selected participants were held. In total there will be two runs in 2021 in order to evaluate the recent version of the training as good as possible. The next and long-term steps will be the firm establishment of a chargeable ‘Climate-Pedagogue’ – Training for every interested person for at least the coming ten years, as well as the strengthening and growing of the network. The presentation will give a short overview about the entire project as well as details about the ‘Climate-Pedagogue’ – Training and some first impressions of the already hold lectures in 2021.</p>

The evolution of the engineered barrier system (EBS) of geological repositories for radioactive waste has been the subject of many research programmes during the last decade. The emphasis of the research activities was on the elaboration of a detailed understanding of the complex thermo-hydro-mechanical-chemical processes, which are expected to evolve in the early post closure period in the near field. It is important to understand the coupled THM-C processes and their evolution occurring in the EBS during the early post-closure phase so it can be confirmed that the safety functions will be fulfilled. Especially, it needs to be ensured that interactions during the resaturation phase (heat pulse, gas generation, non-uniform water uptake from the host rock) do not affect the performance of the EBS in terms of its safety-relevant parameters (e.g. swelling pressure, hydraulic conductivity, diffusivity). The 7th Framework PEBS project (Long Term Performance of Engineered Barrier Systems) aims at providing in depth process understanding for constraining the conceptual and parametric uncertainties in the context of long-term safety assessment. As part of the PEBS project a series of laboratory and URL experiments are envisaged to describe the EBS behaviour after repository closure when resaturation is taking place. In this paper the very early post-closure period is targeted when the EBS is subjected to high temperatures and unsaturated conditions with a low but increasing moisture content. So far the detailed thermo-hydraulic behaviour of a bentonite EBS in a clay host rock has not been evaluated at a large scale in response to temperatures of up to 140°C at the canister surface, produced by HLW (and spent fuel), as anticipated in some of the designs considered. Furthermore, earlier THM experiments have shown that upscaling of thermal conductivity and its dependency on water content and/or humidity from the laboratory scale to a field scale needs further attention. This early post-closure thermal behaviour will be elucidated by the HE-E experiment, a 1:2 scale heating experiment setup at the Mont Terri rock laboratory, that started in June 2011. It will characterise in detail the thermal conductivity at a large scale in both pure bentonite as well as a bentonite-sand mixture, and in the Opalinus Clay host rock. The HE-E experiment is especially designed as a model validation experiment at the large scale and a modelling programme was launched in parallel to the different experimental steps. Scoping calculations were run to help the experimental design and prediction exercises taking the final design into account are foreseen. Calibration and prediction/validation will follow making use of the obtained THM dataset. This benchmarking of THM process models and codes should enhance confidence in the predictive capability of the recently developed numerical tools. It is the ultimate aim to be able to extrapolate the key parameters that might influence the fulfilment of the safety functions defined for the long term steady state.

In this study, the projected future long-term changes of the local wave conditions at the German Baltic Sea coast over the course of the 21st century are analyzed and assessed with special focus on model agreement, statistical significance and ranges/spread of the results. An ensemble of new regional climate model (RCM) simulations with the RCM REMO for three RCP forcing scenarios was used as input data. The outstanding feature of the simulations is that the data are available with a high horizontal resolution and at hourly timesteps which is a high temporal resolution and beneficial for the wind–wave modelling. A new data interface between RCM output data and wind–wave modelling has been developed. Suitable spatial aggregation methods of the RCM wind data have been tested and used to generate input for the calculation of waves at quasi deep-water conditions and at a mean water level with a hybrid approach that enables the fast compilation of future long-term time series of significant wave height, mean wave period and direction for an ensemble of RCM data. Changes of the average wind and wave conditions have been found, with a majority of the changes occurring for the RCP8.5 forcing scenario and at the end of the 21st century. At westerly wind-exposed locations mainly increasing values of the wind speed, significant wave height and mean wave period have been noted. In contrast, at easterly wind-exposed locations, decreasing values are predominant. Regarding the changes of the mean wind and wave directions, westerly directions becoming more frequent. Additional research is needed regarding the long-term changes of extreme wave events, e.g., the choice of a best-fit extreme value distribution function and the spatial aggregation method of the wind data.

Context There is little information available on how research activities might cause stress responses in wildlife, especially responses of threatened species such as the desert tortoise (Gopherus agassizii). Aims The present study aims to detect behavioural effects of researcher handling and winter precipitation on a natural population of desert tortoises in the desert of Southwestern United States, over the period 1997 to 2014, through extensive assessments of capture events during multiple research studies, and capture–mark–recapture survivorship analysis. Methods Juvenile and adult desert tortoises were repeatedly handled with consistent methodology across 18 years during 10 study seasons. Using a generalised linear mixed-effects model, we assessed the effects of both research manipulation and abiotic conditions on probability of voiding. Additionally, we used a Cormack–Jolly–Seber model to assess the effects of winter precipitation and voiding on long-term apparent survivorship. Key results Of 1008 total capture events, voiding was recorded on 83 (8.2%) occasions in 42 different individuals. Our top models indicated that increases in handling time led to significantly higher probabilities of voiding for juveniles, females and males. Similarly, increases in precipitation resulted in significantly higher probabilities of voiding for juveniles and females, but not for males. Tortoise capture frequency was negatively correlated with voiding occurrence. Cormack–Jolly–Seber models demonstrated a weak effect of winter precipitation on survivorship, but a negligible effect for both voiding behaviour and sex. Conclusions Handling-induced voiding by desert tortoises may occur during common research activities and years of above average winter precipitation. Increased likelihood of voiding in individuals with relatively low numbers of recaptures suggested that tortoises may have perceived researchers initially as predators, and therefore voided as a defensive strategy. Voiding does not appear to impact long-term survivorship in desert tortoises at this site. Implications This study has demonstrated that common handling practices on desert tortoise may cause voiding behaviour. These results suggest that in order to minimise undesirable behavioural responses in studied desert tortoise populations, defined procedures or protocols must be followed by the investigators to reduce contact period to the extent feasible.

The study of changes in river discharge is important for regional climate variability characterization and for development of an efficient water resource management system. The hydrological regime of rivers and their long-term changes in Latvia were investigated. Four major types of river hydrological regimes, which depend on climatic and physicogeographic factors, were characterized. These factors are linked to the changes observed in river discharge. Periodic oscillations of discharge, and low- and high-water flow years are common for the major rivers in Latvia. A main frequency of river discharge regime changes of about 20 and 13 years was estimated for the studied rivers. A significant impact of climate variability on the river discharge regime has been found.

Abstract. The Global Climate Observing System (GCOS) Reference Upper Air Network (GRUAN) provides reference quality RS92 radiosonde measurements of temperature, pressure and humidity. A key attribute of reference quality measurements, and hence GRUAN data, is that each datum has a well characterized and traceable estimate of the measurement uncertainty. The long-term homogeneity of the measurement records, and their well characterized uncertainties, make these data suitable for reliably detecting changes in global and regional climate on decadal time scales. Considerable effort is invested in GRUAN operations to (i) describe and analyse all sources of measurement uncertainty to the extent possible, (ii) quantify and synthesize the contribution of each source of uncertainty to the total measurement uncertainty, and (iii) verify that the evaluated net uncertainty is within the required target uncertainty. However, if the climate science community is not sufficiently well informed on how to capitalize on this added value, the significant investment in estimating meaningful measurement uncertainties is largely wasted. This paper presents and discusses the techniques that will need to be employed to reliably quantify long-term trends in GRUAN data records. A pedagogical approach is taken whereby numerical recipes for key parts of the trend analysis process are explored. The paper discusses the construction of linear least squares regression models for trend analysis, boot-strapping approaches to determine uncertainties in trends, dealing with the combined effects of autocorrelation in the data and measurement uncertainties in calculating the uncertainty on trends, best practice for determining seasonality in trends, how to deal with co-linear basis functions, and interpreting derived trends. Synthetic data sets are used to demonstrate these concepts which are then applied to a first analysis of temperature trends in RS92 radiosonde upper air soundings at the GRUAN site at Lindenberg, Germany (52.21° N, 14.12° E).

Objective: The objective of this study was to disseminate advice imparted to early career psychiatrists by a panel of senior colleagues at a Royal Australian and New Zealand College of Psychiatrists symposium, reflecting on things they wished they had known at the earlier stage in their careers. Methods: Key themes were extracted from notes taken at the symposium, where opinions were expressed by three senior psychiatrists. Results: There are components in building a sustainable career as a psychiatrist, which include considering one’s work environment and relationships with colleagues; self-care, mentorship and reflective practice; and seeking opportunities to teach and research for career progression. Conclusions: The mentorship and advice from senior colleagues can be highly influential. In order to sustain a career that has reward, meaning and longevity, psychiatrists would do well to pay attention to aspects of self-care, stay connected to their loved ones, seek an optimal work–life balance and take an interest in their long term career plans.
