Analysis of migrating and non-migrating tides of the Extended Unified Model in the mesosphere and lower thermosphere
Authors: Griffith Matthew J. , Mitchell Nicholas J.
Published: June 2022

Abstract. Atmospheric tides play a key role in coupling the lower, middle, and upper atmosphere/ionosphere. The tides reach large amplitudes in the mesosphere and lower thermosphere (MLT), where they can have significant fluxes of energy and momentum, and so strongly influence the coupling and dynamics. The tides must therefore be accurately represented in general circulation models (GCMs) that seek to model the coupling of atmospheric layers and impacts on the ionosphere. The tides consist of both migrating (sun-following) and non-migrating (not sun-following) components, both of which have important influences on the atmosphere. The Extended Unified Model (ExUM) is a recently developed version of the Met Office's GCM (the Unified Model) which has been extended to include the MLT. Here, we present the first in-depth analysis of migrating and non-migrating components in the ExUM. We show that the ExUM produces both non-migrating and migrating tides in the MLT of significant amplitude across a rich spectrum of spatial and temporal components. The dominant non-migrating components in the MLT are found to be DE3, DW2, and DW3 in the diurnal tide and S0, SW1, and SW3 in the semidiurnal tide. These components in the model can have monthly mean amplitudes at a height of 95 km as large as 35 m s−1/10 K. All the non-migrating components exhibit a strong seasonal variability in amplitude, and a significant short-term variability is evident. Both the migrating and non-migrating components exhibit notable variation with latitude. For example, the temperature and wind diurnal tides maximise at low latitudes and the semidiurnal tides include maxima at high latitudes. A comparison against published satellite and ground-based observations shows generally good agreement in latitudinal tidal structure, with more differences in seasonal tidal structure. Our results demonstrate the capability of the ExUM for modelling atmospheric migrating and non-migrating tides, and this lays the foundation for its future development into a whole atmosphere model. To this end, we make specific recommendations on further developments which would improve the capability of the model.

Abstract. High-silica explosive eruptions are one of the most dangerous natural phenomena, yet it is unclear which processes are involved in this infrequent kind of events. We present the first systematic characterization of near-field seismicity associated to a large high-silica eruption analyzing data recorded before, during and after the June 4th 2011 rhyolitic eruption of Puyehue Cordón Caulle Volcanic Complex (PCCVC). Results of a first-level data processing, developed by The Southern Andean Volcano Observatory (OVDAS) to monitor unrest and the evolution of the eruption, are complemented here with the relocation of hypocenters into a local 1D velocity model, time-series of the b-value and the computation of focal mechanism. This information allows us to define several phases before and after the onset of the eruption, describing details of the space-time evolution of seismicity, defining and characterizing the seismic sources, identifying the structural-control of the magmatic intrusion and stress variations during the eruption. Our results illuminate several underlying processes, with emphasis on the possible role that basement structures had on the storage, transport and evacuation of magma. Integrating our results with previous findings based on satellite geodesy and petrology of erupted materials, we discuss general conceptual models regarding destabilization of structurally-controlled acidic magmatic systems, the pass from unrest to eruption, changes in eruptive style and waning phases of eruptions, with broader implications for monitoring and forecast of violent silicic eruptions.

Abstract. Cosmic-ray neutron sensing (CRNS) has become an effective method to measure soil moisture at a horizontal scale of hundreds of metres and a depth of decimetres. Recent studies proposed operating CRNS in a network with overlapping footprints in order to cover root-zone water dynamics at the small catchment scale and, at the same time, to represent spatial heterogeneity. In a joint field campaign from September to November 2020 (JFC-2020), five German research institutions deployed 15 CRNS sensors in the 0.4 km2 Wüstebach catchment (Eifel mountains, Germany). The catchment is dominantly forested (but includes a substantial fraction of open vegetation) and features a topographically distinct catchment boundary. In addition to the dense CRNS coverage, the campaign featured a unique combination of additional instruments and techniques: hydro-gravimetry (to detect water storage dynamics also below the root zone); ground-based and, for the first time, airborne CRNS roving; an extensive wireless soil sensor network, supplemented by manual measurements; and six weighable lysimeters. Together with comprehensive data from the long-term local research infrastructure, the published data set (available at https://doi.org/10.23728/b2share.756ca0485800474e9dc7f5949c63b872; Heistermann et al., 2022) will be a valuable asset in various research contexts: to advance the retrieval of landscape water storage from CRNS, wireless soil sensor networks, or hydrogravimetry; to identify scale-specific combinations of sensors and methods to represent soil moisture variability; to improve the understanding and simulation of land–atmosphere exchange as well as hydrological and hydrogeological processes at the hillslope and the catchment scale; and to support the retrieval of soil water content from airborne and spaceborne remote sensing platforms.

Abstract. Excessive anthropogenic nitrogen (N) inputs to the biosphere have disrupted the global nitrogen cycle. To better quantify the spatial and temporal patterns of anthropogenic N enrichments, assess their impacts on the biogeochemical cycles of the planet and other living organisms, and improve nitrogen use efficiency (NUE) for sustainable development, we have developed a comprehensive and synthetic dataset for reconstructing the History of anthropogenic N inputs (HaNi) to the terrestrial biosphere. The HaNi dataset takes advantage of different data sources in a spatiotemporally consistent way to generate a set of high-resolution gridded N input products from the preindustrial to present (1860–2019). The HaNi dataset includes annual rates of synthetic N fertilizer, manure application/deposition, and atmospheric N deposition in cropland, pasture, and rangeland at a spatial resolution of 5-arcmin. Specifically, the N inputs are categorized, according to the N forms and land uses, as ten types: 1) NH4+-N fertilizer applied to cropland, 2) NO3-N fertilizer applied to cropland, 3) NH4+-N fertilizer applied to pasture, 4) NO3-N fertilizer applied to pasture, 5) manure N application on cropland, 6) manure N application on pasture, 7) manure N deposition on pasture, 8) manure N deposition on rangeland, 9) NHx-N deposition, and 10) NOy-N deposition. The total anthropogenic N (TN) inputs to global terrestrial ecosystems increased from 29.05 Tg N yr-1 in the 1860s to 267.23 Tg N yr-1 in the 2010s, with the dominant N source changing from atmospheric N deposition (before the 1900s) to manure N (the 1910s–2000s), and to synthetic fertilizer in the 2010s. The proportion of synthetic NH4+-N fertilizer increased from 64 % in the 1960s to 90 % in the 2010s, while synthetic NO3-N fertilizer decreased from 36 % in the 1960s to 10 % in the 2010s. Hotspots of TN inputs shifted from Europe and North America to East and South Asia during the 1960s-2010s. Such spatial and temporal dynamics captured by the HaNi dataset are expected to facilitate a comprehensive assessment of the coupled human-earth system and address a variety of social welfare issues, such as climate-biosphere feedback, air pollution, water quality, and biodiversity.
Assessing the roles emission sources and atmospheric processes play in simulating δ15N of atmospheric NOx and NO3− using CMAQ (version 5.2.1) and SMOKE (version 4.6)
Authors: Fang Huan , Michalski Greg
Published: June 2022

Abstract. Nitrogen oxides (NOx= nitric oxide (NO) + nitrogen dioxide
(NO2)) are important trace gases that affect atmospheric chemistry, air
quality, and climate. Contemporary development of NOx emissions
inventories is limited by the understanding of the roles of vegetation (net
NOx source or net sink), vehicle emissions from gasoline- and
diesel-powered vehicles, the application of NOx emission control
technologies, and accurate verification techniques. The nitrogen stable
isotope composition (δ15N) of NOx is an effective tool to
evaluate the accuracy of the NOx emission inventories, which are based
on different assumptions. In this study, we traced the changes in δ15N values of NOx along the “journey” of atmospheric NOx,
driven by atmospheric processes after different sources emit NOx into the
atmosphere. The 15N was incorporated into the emission input dataset,
generated from the US EPA trace gas emission model SMOKE (Sparse Matrix
Operator Kernel Emissions). Then the 15N-incorporated emission input
dataset was used to run the CMAQ (Community Multiscale Air Quality) modeling
system. By enhancing NOx deposition, we simulated the expected δ15N of NO3-, assuming no isotope fractionation during
chemical conversion or deposition. The simulated spatiotemporal patterns in
NOx isotopic composition for both SMOKE outputs (simulations under
the “emission only” scenario) and CMAQ outputs (simulations under the “emission
+ transport + enhanced NOx loss” scenario) were compared with
corresponding measurements in West Lafayette, Indiana, USA. The simulations
under the emission + transport + enhanced NOx loss scenario were
also compared to δ15N of NO3- at NADP (National
Atmospheric Deposition Program) sites. The results indicate the potential
underestimation of emissions from soil, livestock waste, off-road vehicles,
and natural-gas power plants and the potential overestimation of emissions
from on-road vehicles and coal-fired power plants, if only considering the
difference in NOx isotopic composition for different emission sources.
After considering the mixing, dispersion, transport, and deposition of
NOx emission from different sources, the estimation of atmospheric
δ15N(NOx) shows better agreement (by ∼ 3 ‰) with observations.
Technical Note: Extending the SWAT model to transport chemicals through tile and groundwater flow
Authors: Rathjens Hendrik , Kiesel Jens , Winchell Michael , Arnold Jeffrey , Sur Robin
Published: June 2022

Abstract. The SWAT model is frequently used to simulate the transport of water-soluble chemicals in the environment such as pesticides and their metabolites originating from agricultural applications. However, the model does not simulate the transport of chemicals through subsurface tile drains and groundwater. This limitation is particularly significant in lowland regions and when simulating stable chemicals that can leach to and accumulate in groundwater. To fill this gap, the publicly available SWAT code was modified to complement the simulation of chemicals by adding transport capabilities through tile and groundwater flow. The extended model was tested in two agricultural catchments with a typically used pesticide and one of its metabolites. Results show that the transport of the pesticide is mainly governed by surface runoff and that shallow surface tile flow contributions can be significant. Metabolite concentrations in streamflow are, however, driven by a complex spatial-temporal interplay of all surface and subsurface transport components. This highlights the advantages of applying the modified code in catchment-scale environmental exposure studies and for developing best management practices or mitigation strategies. The new code is made available as an electronic supplement to this technical note.

Abstract. Due to the semi-enclosed nature of the Mediterranean Sea,
natural disasters and anthropogenic activities impose stronger pressures on
its coastal ecosystems than in any other sea of the world. With the aim of
responding adequately to science priorities and societal challenges,
littoral waters must be effectively monitored with high-frequency radar
(HFR) systems. This land-based remote sensing technology can provide, in
near-real time, fine-resolution maps of the surface circulation over broad
coastal areas, along with reliable directional wave and wind information.
The main goal of this work is to showcase the current status of the
Mediterranean HFR network and the future roadmap for orchestrated actions.
Ongoing collaborative efforts and recent progress of this regional alliance
are not only described but also connected with other European initiatives
and global frameworks, highlighting the advantages of this cost-effective
instrument for the multi-parameter monitoring of the sea state. Coordinated
endeavors between HFR operators from different multi-disciplinary
institutions are mandatory to reach a mature stage at both national and
regional levels, striving to do the following: (i) harmonize deployment and maintenance
practices; (ii) standardize data, metadata, and quality control procedures;
(iii) centralize data management, visualization, and access platforms; and (iv) develop practical applications of societal benefit that can be used for
strategic planning and informed decision-making in the Mediterranean marine
environment. Such fit-for-purpose applications can serve for search and
rescue operations, safe vessel navigation, tracking of marine pollutants,
the monitoring of extreme events, the investigation of transport processes,
and the connectivity between offshore waters and coastal ecosystems.
Finally, future prospects within the Mediterranean framework are discussed
along with a wealth of socioeconomic, technical, and scientific challenges
to be faced during the implementation of this integrated HFR regional
network.

Abstract. The Mediterranean Sea is a prominent climate-change hot
spot, with many socioeconomically vital coastal areas being the most
vulnerable targets for maritime safety, diverse met-ocean hazards and marine
pollution. Providing an unprecedented spatial and temporal resolution at
wide coastal areas, high-frequency radars (HFRs) have been steadily gaining
recognition as an effective land-based remote sensing technology for
continuous monitoring of the surface circulation, increasingly waves and
occasionally winds. HFR measurements have boosted the thorough scientific
knowledge of coastal processes, also fostering a broad range of
applications, which has promoted their integration in coastal ocean
observing systems worldwide, with more than half of the European sites
located in the Mediterranean coastal areas. In this work, we present a
review of existing HFR data multidisciplinary science-based applications in
the Mediterranean Sea, primarily focused on meeting end-user and
science-driven requirements, addressing regional challenges in three main
topics: (i) maritime safety, (ii) extreme hazards and (iii) environmental
transport process. Additionally, the HFR observing and monitoring regional
capabilities in the Mediterranean coastal areas required to underpin the
underlying science and the further development of applications are also
analyzed. The outcome of this assessment has allowed us to provide a set of
recommendations for future improvement prospects to maximize the
contribution to extending science-based HFR products into societally
relevant downstream services to support blue growth in the Mediterranean
coastal areas, helping to meet the UN's Decade of Ocean Science for
Sustainable Development and the EU's Green Deal goals.
Improving Models to Predict Holocellulose and Klason Lignin Contents for Peat Soil Organic Matter with Mid Infrared Spectra
Authors: Teickner Henning , Knorr Klaus-Holger
Published: June 2022

Abstract. To understand global soil organic matter (SOM) chemistry and its dynamics, we need tools to efficiently quantify SOM properties, for example prediction models using mid infrared spectra. However, the advantages of such models rely on their validity and accuracy. Recently, Hodgkins et al. (2018) developed models to quantitatively predict organic matter holocellulose and Klason lignin contents, two indicators of SOM stability and major fractions of organic matter. The models may have the potential to understand large-scale SOM gradients and have been used in various studies. A research gap to fill is that these models have not been validated in detail yet. What are their limitations and how can we improve them? This study provides a validation with the aim to identify concrete steps to improve these models. As a first step, we provide several improvements using the original training data. The major limitation we identified is that the original training data are not representative for a range of diverse peat samples. This causes both biased estimates and extrapolation uncertainty under the original models. In addition, the original models can in practice produce unrealistic predictions (negative values or values >100 mass-%). Our improved models partly reduce the observed bias, have a better predictive performance for the training data, and avoid such unrealistic predictions. Finally, we provide a proof-of-concept that holocellulose contents can also be predicted for mineral-rich samples. A key step to improve the models will be to collect training data that is representative for SOM formed under various conditions. This study opens directions to develop operational models to predict SOM holocellulose and Klason lignin contents from mid infrared spectra.
Acute Cardiovascular and Metabolic Effects of Different Warm-Up Protocols on Dynamic Apnea
Authors: Vitali Luca , Raffi Milena , Piras Alessandro
Published: June 2022

The aim of this study was to evaluate the acute physiological response to different warm-up protocols on the dynamic apnea performance. The traditional approach, including a series of short-mid dives in water (WET warm-up), was compared to a more recent strategy, consisting in exercises performed outside the water (DRY warm-up). Nine athletes were tested in two different sessions, in which the only difference was the warm-up executed before 75m of dynamic apnea. Heart rate variability, baroreflex sensitivity, hemoglobin, blood lactate and the rate of perceived exertion were recorded and analyzed. With respect to WET condition, DRY showed lower lactate level before the dive (1.93 vs. 2.60 mmol/L, p = 0.006), higher autonomic indices and lower heart rate during the subsequent dynamic apnea. A significant correlation between lactate produced during WET with the duration of the subsequent dynamic apnea, suggests that higher lactate levels could affect the dive performance (72 vs. 70 sec, p = 0.028). The hemoglobin concentration and the rate of perceived exertion did not show significant differences between conditions. The present findings partially support the claims of freediving athletes who adopt the DRY warm-up, since it induces a more pronounced diving response, avoiding higher lactate levels and reducing the dive time of a dynamic apnea.
Internal Validity in Resistance Training Research: A Systematic Review
Authors: Makaruk Hubert , Starzak Marcin , Płaszewski Maciej , Winchester Jason B.
Published: June 2022

Ensuring internal validity is the key procedure when planning the study design. Numerous systematic reviews have demonstrated that considerations for internal validity do not receive adequate attention in the primary research in sport sciences. Therefore, the purpose of this study was to review methodological procedures in current literature where the effects of resistance training on strength, speed, and endurance performance in athletes were analyzed. A computer-based literature searches of SPORTDiscus, Scopus, Medline, and Web of Science was conducted. The internal validity of individual studies was assessed using the PEDro scale. Peer-reviewed studies were accepted only if they met all the following eligibility criteria: (a) healthy male and female athletes between the ages of 18-65 years; (b) training program based on resistance exercises; (c) training program lasted for at least 4 weeks or 12 training sessions, with at least two sessions per week; (d) the study reported maximum strength, speed, or endurance outcomes; and (e) systematic reviews, cohort studies, case-control studies, cross-sectional studies were excluded. Of the 6,516 articles identified, 133 studies were selected for rating by the PEDro scale. Sixty-eight percent of the included studies used random allocation to groups, but only one reported concealed allocation. Baseline data are presented in almost 69% of the studies. Thirty-eight percent of studies demonstrated adequate follow-up of participants. The plan to follow the intention-to-treat or stating that all participants received training intervention or control conditions as allocated were reported in only 1.5% of studies. The procedure of blinding of assessors was also satisfied in only 1.5% of the studies. The current study highlights the gaps in designing and reporting research in the field of strength and conditioning. Randomization, blinding of assessors, reporting of attrition, and intention-to-treat analysis should be more fully addressed to reduce threats to internal validity in primary research.
A divided diocese at the end of the Christian world. The case of the bishopric of Włocławek
Authors: Maciejewski Jacek
Published: June 2022

The construction of the gothic cathedral church in Włocławek on the new site by the local bishops, after the former one was burned down by the knights of the Teutonic Order in 1329, coincides with a time of political consolidation of the Kingdom of Poland and a significant reinforcement of the power of Polish kings. For that frontier bishopric, situated in the northern part of the country, it was also a period of stabilization and strengthening of diocesan structures. The earlier history of this diocese, however, was marked by divisions and political rivalry, as well as by an interesting institutional dualism. In my paper, I focus my attention on the period between 1123/1124 – 1330 and on showing how local bishops and chapters built the ecclesiastical structures of this long politically fragmented diocese which initially encompassed some areas that had to be christianised. I also intend to show the ways in which Kuyavian bishops dealt with the problem of loyalty to the rulers, sometimes hostile to each other, while maintaining of interests and well-being of their bishopric.
The relationship between the bishop and the cathedral chapter in light of institutional changes in the communal era: Two examples from the Istrian Peninsula
Authors: Jenko Kovačič Ana
Published: June 2022

The second half of the 12th and the 13th century witnessed great institutional changes in Istrian towns due to the formation of communal government. This process, well-known in the Italian environment, included a certain degree of conflicts of interest with the local bishops. Two examples from Istria, namely the cities of Trieste and Poreč (Parenzo), lend themselves to interesting research. The bishops of Trieste, who held the public authority within the city walls from the mid-10th century onwards, presented a direct obstacle to the commune on its way towards complete autonomy. On the other hand, the bishops in Poreč understood the territory of the city district as the bishopric’s property. Their aspirations, which were based on the forged Privilegium Eufrasianum, also included fiscal and juridical powers and thus posed a problem for the communal development. Communes finally overcame both specific local situations; however, it is interesting to note that the reactions of the cathedral chapters differed greatly. Members of the chapter in Poreč stood by the bishop in his fight against the commune, which was backed by the power of Venice. Their counterparts in Trieste, though not so actively involved in the shift of the public power in the city, can eventually be regarded as the commune’s allies. The reasons for such different responses can be found not only in the practical, financial aspects, but also in the different relations within the bishopric in the previous centuries. Although cathedral chapters were not directly involved in the conflict and in the institutional changes per se, research into the relationship between chapters and bishops can provide an insight into bishoprics’ internal mechanisms that set the foundations for the late medieval and early modern period.

Over the past few decades, the field of minimally invasive cardiac surgery has significantly broadened. Novel surgical and endovascular techniques have been developed for the treatment of aortic valve pathologies. Surgical aortic valve replacement (SAVR) through a right antero-lateral (mini-)thoracotomy (RALT) has gained approval due to its limited postoperative trauma, faster rehabilitation and sufficient pain control. Nevertheless, SAVR RALT has not been adopted by a significant proportion of cardiac surgeons, due, in part, to its technical complexity and steep learning curve. In this review, we discuss the data for minimally invasive aortic valve surgery and describe our operative technique for SAVR RALT.

The use of the distal femoral replacement (DFR) has grown in recent years. Historically, this procedure was reserved for malignancy and complex revision cases with relative success. In recent years, complex reconstruction cases have had relative success. DFR has been associated with a range of complications including anterior knee pain, patellar instability, limitations in knee motion, and rotational instability that are sequelae of altered patello-femoral mechanics. Thus, subsequent dysfunction may require revision. To our knowledge, no surgical technique to correct DFR patello-femoral maltracking has been demonstrated in current literature. We present a surgical technique for DFR patello-femoral maltracking corrected surgically with femoral component revision and femoral stem retention.

At present, successful companies are those which, compared to their competitors, are concerned with aspects of sustainable development. Indeed, the practice of sustainable development is more or less used by PMEs to distinguish themselves and preserve their image. But the question is how do PMEs integrate themselves into the practice of sustainable development? Sustainable development could be considered as a new project for society, a new stage in the organisation of human activities, which requires cultural factors to be taken into account, because taking sustainable development into account is first and foremost a matter of culture before becoming an economic concern. Based on the hypothesis that the culture of sustainable development holds an important place in the integration of companies in the practice of sustainable development, the objective of this study is to analyse qualitatively, through the results of interviews with twenty Malagasy PMEs, the importance of the culture of sustainable development in the practice of sustainable development.
