      The "Did this really happen'!" project aims at publishing real-life, everyday sexism in the form of comic strips. Its major goal is to raise awareness about unconscious biases that transpire in everyday interactions in academia and increase the visibility of sexist situations that arise within the scientific community, especially to those who might not notice it. In this publication, we present the project and the different recurring sexist behaviours identified in the collected stories.

  • Copernicus Sentinel-1 satellites: sensitivity of antenna offset estimation

    • Abstract: Copernicus Sentinel-1 satellites: sensitivity of antenna offset estimation to orbit and observation modelling
      Heike Peter, Jaime Fernández, and Pierre Féménias
      Adv. Geosci., 50, 87–100, https://doi.org/10.5194/adgeo-50-87-2020, 2020
      The SAR Copernicus Sentinel-1 satellites require a high orbit accuracy of 5 cm in comparison to external processing facilities. Orbit analyses showed discrepancies between the results of the two Sentinel-1 satellites being identical in construction. Follow-up estimation of GPS antenna offsets shows the sensitivity to different orbit and observation models. Consistent results may be achieved for both satellites when applying estimated antenna offsets considering self-shadowing assumptions.

      Adv. Geosci., 50, 77–86, https://doi.org/10.5194/adgeo-50-77-2020, 2020
      Tropospheric delays must be taken into account when analyzing GNSS data. Several tropospheric delay models and mapping functions are available, for instance the Vienna Mapping Functions 1 (VMF1) and the Global Mapping Function (GMF). Recently, a refined version of VMF1, VMF3, has been released. This study aims to assess the performance of VMF3 for GNSS observations in Indonesia, by analyzing the data using Bernese GNSS Software, version 5.2 with Precise Point Positioning method.

    • Abstract: Time evolution of medium and long-period ground tilting at Campi Flegrei caldera
      Simona Petrosino, Ciro Ricco, Enza De Lauro, Ida Aquino, and Mariarosaria Falanga
      Adv. Geosci., 52, 9–17, https://doi.org/10.5194/adgeo-52-9-2020, 2020
      We analyse tiltmeter time series recorded from April 2015 to March 2019 at three borehole instruments installed at Campi Flegrei caldera (Italy). We evaluate the crustal response in terms of ground tilting to external excitations of medium/long-period tidal constituents.The results indicate that the tidal tilting is mainly controlled by the local stress field distribution and rheology; in addition, seasonal exogenous factors like rainfalls play a role in modulating the ground deformation.

  • Assessment of local covariance estimation through Least Squares
           Collocation over Iran

    • Abstract: Assessment of local covariance estimation through Least Squares Collocation over Iran
      Sabah Ramouz, Yosra Afrasteh, Mirko Reguzzoni, and Abdolreza Safari
      Adv. Geosci., 50, 65–75, https://doi.org/10.5194/adgeo-50-65-2020, 2020
      Covariance determination as the heart of Least Squares Collocation gravity field modeling is based on fitting an analytical covariance to the empirical covariance, which is stemmed from gravimetric data. The main objective of this study is to process different local covariance strategies over four regions with different topography and spatial data distribution in Iran. For this purpose, Least Squares Collocation based on Remove – Compute – Restore technique is implemented. In the Remove step, gravity reduction in regions with a denser distribution and a rougher topography is more effective. In the Compute step, the assessment of the Collocation estimates on the gravity anomaly control points illustrates that data density is more relevant than topography roughness to have a good covariance determination. Moreover, among the different attempts of localizing the covariance estimation, a recursive approach correcting the covariance parameters based on the agreement between Least Squares Collocation estimates and control points shows better performance. Furthermore, we could see that covariance localization in a region with sparse or bad distributed observations is a challenging task and may not necessarily improve the Collocation gravity modeling. Indeed, the geometrical fitness of the empirical and analytical covariances – which is usually a qualitative test to verify the precision of the covariance determination – is not always an adequate criterion.

  • Multi-constellation GNSS orbit combination based on MGEX products

    • Abstract: Multi-constellation GNSS orbit combination based on MGEX products
      Gustavo Mansur, Pierre Sakic, Benjamin Männel, and Harald Schuh
      Adv. Geosci., 50, 57–64, https://doi.org/10.5194/adgeo-50-57-2020, 2020
      Nowadays, new GNSS, like European Galileo or Chinese Beidou are available. Some members of the International GNSS Service (IGS) provide multi-GNSS precise satellite orbits, but no final orbit combination exists yet. We developed a new algorithm to combine satellite orbits for all GNSS constellations. Two different strategies were applied. To validate our results we compared our GPS orbits with the official IGS orbits. Our results show that the best strategy applied reached an agreement ~15 mm.

      We have developed a first Germany-wide 3D data-based density and temperature model integrating geoscientific observations and physical processes. The model can serve as a reference for local detailed studies dealing with temperature, pressure, stress, subsidence and sedimentation. Our results help to improve subsurface utilization concepts, reveal current geomechanical conditions crucial for hazard assessment and gather information on viable resources such groundwater and deep geothermal energy.

      In this paper we investigate the application of a solar-powered bus route to a small-scale transportation system, as such of a university campus. We investigate three different scenarios: (1) solar panels installed on the roof of bus stop shelters, (2) solar panels installed at unused open space in the university, and (3) solar roads, i.e. roads constructed by photovoltaic (PV) materials. We conclude that scenario (2) presents the lowest capital cost in relation to energy generation.

      Adv. Geosci., 52, 1–8, https://doi.org/10.5194/adgeo-52-1-2019, 2019
      We study oscillations recorded at Stromboli and Campi Flegrei by different sensors. Seismicity and deformation are investigated on several time scales in order to identify the basic elements of their interaction, whose understanding should provide new insights on the predictive models. At Stromboli, a departure from the equilibrium state is marked by solid tide variations in a certain frequency band. At Campi Flegrei diurnal to annual solid tides modulate an increase of volcanic activity.

      Here, three schemes have been considered for remedying the rank deficiency of the GNSS tomography problem. For this purpose, the Virtual Reference Stations (VRS) and horizontal and vertical constraints have been defined to analyze the impact of different constraints on the accuracy of the reconstructed refractivity field. The obtained results illustrate that applying VRS stations in the sparse GNSS Network can lead to a better solution compared to applying horizontal and vertical constraints.

      In this article we analyze the benefit of computing a combined solution from individual orbit solutions for the low Earth orbiting satellite Sentinel-3A. The selected combination scheme for calculating the combined solution is Variance Component Estimation. It could be shown that a combination of individual solutions can be beneficial in terms of Satellite Laser Ranging validation. In our opinion the findings are well transferable to other satellite missions.

      The Waiwera aquifer hosts a structurally complex geothermal groundwater system, where a localized thermal anomaly feeds the thermal reservoir. The temperature anomaly is formed by the mixing of waters from three different sources: fresh cold groundwater, cold seawater and warm geothermal water. The stratified reservoir rock has been tilted, folded, faulted, and fractured by tectonic movement, providing the pathways for the groundwater. Characterization of such systems is challenging, due to the resulting complex hydraulic and thermal conditions which cannot be represented by a continuous porous matrix. By using discrete fracture network models (DFNs) the discrete aquifer features can be modelled, and the main geological structures can be identified. A major limitation of this modelling approach is that the results are strongly dependent on the parametrization of the chosen initial solution. Classic inversion techniques require to define the number of fractures before any interpretation is done. In this research we apply the transdimensional DFN inversion methodology that overcome this limitation by keeping fracture numbers flexible and gives a good estimation on fracture locations. This stochastic inversion method uses the reversible-jump Markov chain Monte Carlo algorithm and was originally developed for tomographic experiments. In contrast to such applications, this study is limited to the use of steady-state borehole temperature profiles – with significantly less data. This is mitigated by using a strongly simplified DFN model of the reservoir, constructed according to available geological information. We present a synthetic example to prove the viability of the concept, then use the algorithm on field observations for the first time. The fit of the reconstructed temperature fields cannot compete yet with complex three-dimensional continuum models, but indicate areas of the aquifer where fracturing plays a big role. This could not be resolved before with continuum modelling. It is for the first time that the transdimensional DFN inversion was used on field data and on borehole temperature logs as input.

  • Regional hydraulic model of the Upper Rhine Graben

    • Abstract: Regional hydraulic model of the Upper Rhine Graben
      Nora Koltzer, Magdalena Scheck-Wenderoth, Mauro Cacace, Maximilian Frick, and Judith Bott
      Adv. Geosci., 49, 197–206, https://doi.org/10.5194/adgeo-49-197-2019, 2019
      In this study we investigate groundwater flow in the deep subsurface of the Upper Rhine Graben. We make use of a 3-D numerical model covering the entire Upper Rhine Graben. The deep hydrodynamics are characterized by fluid flow from the graben flanks towards its center and in the southern half of the graben from south to north. Moreover, local heterogeneities in the shallow flow field arise from the interaction between regional groundwater flow and the heterogeneous sedimentary configuration.

  • Future TRFs and GGOS – where to put the next SLR station'

    • Abstract: Future TRFs and GGOS – where to put the next SLR station'
      Alexander Kehm, Mathis Bloßfeld, Peter König, and Florian Seitz
      Adv. Geosci., 50, 17–25, https://doi.org/10.5194/adgeo-50-17-2019, 2019
      Satellite Laser Ranging is one of the four fundamental geodetic space techniques for the accurate determination of geodetic key parameters related to the Earth’s geometry, rotation and gravity field. As the current global SLR station distribution is quite inhomogeneous, a simulation study has been performed in order to determine locations on Earth where additional SLR sites will be most valuable for an improvement of the results, the Antarctic region having been identified as a first priority.

  • Storm Tilo over Europe in November 2007: storm surge and impacts on
           societal and energy infrastructure

    • Abstract: Storm Tilo over Europe in November 2007: storm surge and impacts on societal and energy infrastructure
      Anthony James Kettle
      Adv. Geosci., 49, 187–196, https://doi.org/10.5194/adgeo-49-187-2019, 2019
      Storm Tilo on 8–9 November 2007 ranks among the serious winter storms in northern Europe over the past 30 years. Its low pressure centre passed across the northern North Sea, and this led to a cold air outbreak in northwest Europe. Strong north winds across the North Sea contributed to a high storm surge that was serious for coastal regions in eastern England, the Netherlands and Germany. Storm winds and unusually high waves caused shipping accidents and damage to some offshore energy infrastructure. This report presents an outline of the met-ocean conditions and a short overview of storm impacts on societal and energy infrastructure. The progress of the storm surge around the North Sea is analysed using data from the national tide gauge networks. A spectral analysis of the water level data is used to isolate the long period storm surge and short period oscillations (i.e.,

    • Abstract: Understanding the evolution of nuclear waste repositories by performing appropriate experiments – selected investigations at Mont Terri rock laboratory
      Kristof Schuster, Markus Furche, Hua Shao, Jürgen Hesser, Jan-Martin Hertzsch, Werner Gräsle, and Dorothee Rebscher
      Adv. Geosci., 49, 175–186, https://doi.org/10.5194/adgeo-49-175-2019, 2019
      The Federal Institute for Geosciences and Natural Resources (BGR) performs experiments in the Swiss Mont Terri rock laboratory to obtain a comprehensive understanding of the evolution of a repository. Activities and results by BGR from actual and still ongoing experiments are presented exemplarily focusing on main aspects regarding the behaviour of underground facilities. BGR's focus lies mainly on aspects of the construction, post-closure transient, and partly post-closure equilibrium phases.

    • Abstract: Earth rotation variations observed by VLBI and the Wettzell “G” ring laser during the CONT17 campaign
      Sigrid Böhm, Matthias Schartner, André Gebauer, Thomas Klügel, Ulrich Schreiber, and Torben Schüler
      Adv. Geosci., 50, 9–15, https://doi.org/10.5194/adgeo-50-9-2019, 2019
      The precise knowledge of the orientation of an Earth fixed coordinate system with respect to space is of great importance for all tasks of positioning and navigation. In this work we investigated the potential of combining measurements of Very Long Baseline Interferometry and a large ring laser gyroscope to derive highly resolved parameters describing this orientation. The ring laser is not yet at the same level of accuracy and therefore does not substantially influence the results.
