Published: October 2024

Objectives: E-health programs may be an excellent strategy to overcome some barriers related to the non-practice of exercise among pregnant women with obesity. This study aims to present a monitored exercise program for pregnant women with obesity using the Sword Phoenix® biofeedback system; and to evaluate pregnant women's perception of the biofeedback system and the exercise program protocol. Methods: A pre-experimental research was done through a One-shot case study design. Twelve pregnant women with Body Mass Index ≥ 30 kg/m2, were invited to perform for two weeks a home-based structured exercise program protocol with a digital biofeedback system, during exercise the women used an accelerometer to measure the intensity of the exercises. At the end of the two-week exercise period, the pregnant women filled in a questionnaire to assess their perception of usability, satisfaction, safety and motivation regarding exercise program and biofeedback system. Results: The accelerometry results indicate that, during the exercise program protocol, the pregnant women spent 79.3% of the time in moderate activities. The adherence to the program had an average performance of 40%. The results of the questionnaire demonstrated that 100% (n=12) of the participants enjoyed the system and recognized it as a safe instrument with the potential to increase physical activity during pregnancy.
Discussion: The biofeedback system can be a useful tool for implementing an exercise program for pregnant women with obesity. The proposed exercise program complies with international recommendations for physical exercise during pregnancy, ensuring safety. Additionally, it reduces the team intervention, increases participant motivation, and has the potential to reduce sedentary behavior in pregnant women with obesity.

Published: October 2024

The importance of training for effective performance in high-stakes, high-risk work settings is well-known. Successful training is the systematic acquisition of skills, rules, concepts or attitudes that result in improved work performance. Simply exposing people to training situations is not sufficient for them to develop knowledge and skills. This will only occur if the activity results in learning. While much training focuses on the development of technical skills, it is important to train people in non-technical skills, such as decision-making. This paper presents the results of a literature review of 95 peer-reviewed articles that consider the current training and exercise practices used to develop emergency management decision-making capability. The different approaches to training can be categorised into 4 types: discussion-based, operation-based, E-based and post-incident debriefs. This paper discusses current practice in emergency management decision-making training in each of these categories together with studies that have evaluated their effectiveness noting the generally limited nature of evaluation studies. To promote evaluation of training, several studies have developed tools to assess the effectiveness of training. Finally, key takeaway points related to emergency management organisational training and exercise programs are provided.

Published: October 2024

Globally, the frequency and magnitude of weather-related hazards poses significant challenges for governments and the private and the not-for-profit sectors. This paper provides exploratory insight into the challenges that hinder institutional responses to risk reduction. This study specifically considered public sector organisations within disaster risk reduction (DRR) organisational fields. The paper identifies 3 major constraints, which include fragmentation, difficulties in using risk information and cultural identities that affect public sector organisations and community responses. To analyse these issues, an institutional theory lens was used to explain the antecedents under which institutional actors may respond based on events and stakeholder expectations and demands. The findings suggest that challenges hindering response to risks and emergencies are strategic, institutional or operational in nature. A selection of public sector organisations response initiatives is presented within an Australian context with analysis of the Sendai Framework for Disaster Risk Reduction 2015-2023 Priority 4. Recommendations and further research to identify and address other institutional constraints and sectors are recommended.

Published: October 2024

Continuous urbanization and industrialization has to led to increase in volume and type of waste generated. It is estimated that in 2006 the total amount of municipal solid waste generated globally reached 2.02 billion tones, representing a 7% annual increase since 2003 (Global Waste Management Market Report 2007). This poses a problem for local and national governments to ensure sustainable and effective waste management. Technology always helps mankind in making life easier. In public places, proper disposal of waste is not being followed which causes overflow of waste in dustbins that has become a threat to the environment. Segregation, management, transport and disposal of waste plays an important role to minimize the risk to the public and environment. The economic value of waste is best realized when it is segregated. Currently there is no such system of segregation of dry, wet and metallic wastes at a household level. This paper is an innovative way to revolutionize the waste management system using sensors. Segregation is achieved using respective automated sensors and the level of dustbins are monitored simultaneously. Presently there's no such system for segregation of dry and wet wastes at domestic level or social unit level. This paper proposes an automated sensor based waste management and segregation system. It is designed to sort the refuse into 2 categories: wet and dry (metal).

Published: October 2024

La preocupación por la sostenibilidad y la reducción del consumo energético ha impulsado la utilización de la energía solar para accionar las bombas utilizadas para riego agrícola. La energía capturada por los paneles solares es variable a lo largo del tiempo, por lo que es necesario modificar el funcionamiento de las bombas para ajustarse a la energía disponible. El presente trabajo plantea una metodología que utiliza las leyes de la semejanza hidrodinámica de manera completa sin simplificaciones para optimizar el número de bombas funcionando en cada instante y la potencia total instalada en el aprovechamiento fotovoltaico. La utilización de la hipótesis de homología muestra que en la mayoría de los casos la potencia instalada sería insuficiente. Por el contrario, la metodología propuesta proporcionaría diseños adecuados en todos los casos. El artículo se completa con la aplicación a un caso de estudio para mostrar la adecuación del método a una instalación de bombeo a balsa. Por último, se ha realizado un estudio básico de la viabilidad económica obteniendo como resultado un periodo de recuperación de la inversión en torno a los 7 años.

An advanced spatial coregistration of cloud properties for the atmospheric Sentinel missions: application to TROPOMI

Published: October 2024

Abstract. The retrieval of cloud parameters from the atmospheric Sentinel missions requires Earth reflectance measurements from a set of spectral bands. The ground pixels of the involved spectral bands should be fully aligned, but when they are not, special treatment is required within the operational algorithms. This so-called inter-band spatial misregistration of passive spectrometers is present when the Earth reflectance measurements in different spectral bands are captured by different spectrometers. The cloud retrieval algorithm requires reflectance measurements in the UV(ultraviolet)–VIS (visible) band, where the first cloud parameter (i.e., radiometric cloud fraction) is retrieved from OCRA (Optical Cloud Recognition Algorithm). In addition, Earth reflectances in the NIR (near-infrared) band are needed for the retrieval of two additional cloud parameters (i.e., cloud height and cloud albedo or cloud-top height and optical thickness) from the ROCINN (Retrieval of Cloud Information using Neural Networks) algorithm. In the former TROPOMI (TROPOspheric Monitoring Instrument)/S5P (Sentinel-5 Precursor) retrieval, a coregistration scheme of the derived cloud parameters from the source band to the target band based on pre-calculated mapping weights from UV–VIS to NIR and vice versa is applied. In this paper we present a new scheme for the coregistration of the TROPOMI cloud parameters using collocated VIIRS (Visible Infrared Imaging Radiometer Suite)/SNPP (Suomi National Polar-orbiting Partnership) information. The new coregistration scheme based on the VIIRS data improves the TROPOMI cloud product quality and allows the addition of cloud information for the first (westernmost) TROPOMI UVIS ground pixel. In practice, the latter means that a significant number of valid data points are included in the TROPOMI cloud, total ozone, SO2 and HCHO product since 26 November 2023 (orbit 31705), when the new coregistration scheme became operational. From a comparison analysis between the two techniques, we found that the largest differences mainly appear for inhomogeneous scenes. From a validation exercise of TROPOMI against VIIRS in the across-track direction, we found that the old coregistration scheme tends to smooth out cloud structures along the scan line, whereas such structures can be maintained with the new scheme. The need to implement a similar inter-band spatial coregistration scheme is foreseen for the Sentinel-4/MTG-S (Meteosat Third Generation – Sounder) and Sentinel-5/MetOp-SG (Meteorological Operational Satellite – Second Generation) missions. In the case of the Sentinel-4 instrument, the external cloud information will originate from collocated data captured by the FCI (Flexible Combined Imager) on board the MTG-I (Meteosat Third Generation – Imager) satellite.
Moana Ocean Future Climate V1.0: High Resolution Marine Climate Futures For The New Zealand Region

Published: October 2024

Abstract. We have produced a series of 5 km resolution future climate dynamic downscalings for the ocean surrounding New Zealand covering CMIP6 reference conditions; SSP2-4.5 and SSP3-7.0 emissions trajectories. These downscalings combine the Moana Backbone 5 km resolution ROMS configuration with lateral boundary forcing from the 15 km resolution New Zealand Earth System Model (NZESM) and atmospheric forcing from the New Zealand Regional Climate Model 12 km atmospheric model. We validated our reference period downscaling against the Moana Ocean Hindcast and find reasonable agreement to the west and north of New Zealand, but significant disagreement in the region of the Sub-Tropical Front to the east and southeast of the domain. This disagreement is consistent with known issues with the version of NZESM used as forcing in this study. We see similar relative rates of increase in Ocean Heat Content in the upper ocean and mode waters all around New Zealand, but in the deeper ocean the rate of warming is stronger in the Tasman Sea and Antarctic Circumpolar Current than in the Sub Tropical Front East of New Zealand. We examine the occurrence of Marine Heat Waves (MHWs) and find that the use of a “fixed" baseline or one that takes into consideration a long-term warming based on the historical period results in important differences in the estimated number of days under MHWs for mid and end-of-the-century scenarios.
From small scale variability to mesoscale stability in surface ocean pH: implications for air-sea CO2 equilibration
Authors: Delaigue Louise , Reichart Gert-Jan , Galley Chris , Ourradi Yasmina , Humphreys Matthew Paul
Published: October 2024

Abstract. One important aspect of understanding ocean acidification is the nature and drivers of pH variability in surface waters on smaller spatial (i.e., areas up to 100 km2) and temporal (i.e., days) scales. However, there has been a lack of high-quality pH data at sufficiently high resolution. Here, we describe a simple optical system for continuous high-resolution surface seawater pH measurements. The system includes a PyroScience pH optode placed in a flow-through cell directly connected to the underway supply of a ship through which near-surface seawater is constantly pumped. Seawater pH is measured at a rate of 2 to 4 measurements min-1 and is cross-calibrated using discrete carbonate system observations (total alkalinity, dissolved inorganic carbon and nutrients). This setup was used during two research cruises in different oceanographic conditions: the North Atlantic Ocean (December–January 2020) and the South Pacific Ocean (February–April 2022). Our findings reveal fine-scale fluctuations in surface seawater pH across the North Atlantic and South Pacific Oceans. While temperature is a significant abiotic factor driving these variations, it does not account for all observed changes. Instead, our results highlight the interplay between temperature, biological activity, and water masses on pH. Notably, the variability differed between the two regions, suggesting differences in the dominant factors influencing pH. In the South Pacific, biological processes appeared to be mostly responsible for pH variability, while in the North Atlantic, additional abiotic and biotic factors complicated the correlation between expected and observed pH changes. Although surface seawater pH exhibited fine-scale variations, it remained relatively stable over a 24-hour cycle due to reequilibration with atmospheric CO2. Thus, for the regions and time periods studied, ocean basin-scale analyses based on discrete samples collected during traditional research cruise transects would still capture the necessary variability for global CO2 cycle assessments and their implications.
Low-level jets in the North and Baltic Seas: Mesoscale Model Sensitivity and Climatology
Authors: Olsen Bjarke Tobias Eisensøe , Hahmann Andrea  Noemi , Alonso-de-Linaje Nicolás González , Žagar Mark , Dörenkämper Martin
Published: October 2024

Abstract. Low-level jets (LLJs) are wind speed maxima in the lower part of the atmospheric boundary layer. Accurately accounting for these mesoscale phenomena in wind resource assessment is increasingly important as the height of wind turbines continues to grow. During LLJ events, wind speeds increase, leading to a general increase in power output. We utilize wind measurements from LiDARs and a mast for five sites in the North and Baltic Seas to assess the quality of the WRF model simulations for LLJ characterization. We also investigate the benefits of using the WRF model simulations compared to the widely used ERA5 reanalysis. In the WRF model simulations, we vary the grid spacing, vertical resolution, and the planetary boundary layer and land surface schemes, parameters we deemed most likely to have a substantial impact. The model’s performance is evaluated based on its ability to replicate observed distributions of LLJs and relevant associated characteristics, such as the shear and veer across the rotor-plane of typical large offshore wind turbines (30 m to 300 m). Finally, we generate a five-year LLJ climatology based on using the best-evaluated model configuration. The modeling results show a strong dependency of the LLJ representation and the associated wind profiles on the WRF model configuration and that relying on ERA5 for LLJ characterization is insufficient. For example, the LLJ rate-of-occurrence varied by up to a factor of three or more between some WRF model runs. The simulation using the optimized model configuration more accurately reflects the frequency, intensity, and vertical extension of LLJs, as confirmed by LiDAR data. In the North and Baltic Seas, LLJs occur along the western sea basins around 10–15 % of the time, with average jet heights between 140–220 meters, which are well within the height of operation of modern wind turbines. The most LLJ-prone region is east of southern Sweden, especially during spring and summer. These mesoscale phenomena contribute to up to 30 % of the wind capacity in some areas in this season. Analysis of the five-year modeled LLJ climatology in the North and Southern Baltic Seas gives insights into the physical mechanisms that create them.
POPE: a Global Gridded Emission Inventory for PFAS 1950–2020
Authors: Simon Pascal , Ramacher Martin Otto Paul , Hagemann Stefan , Matthias Volker , Joerss Hanna , Bieser Johannes
Published: October 2024

Abstract. This study presents a global multi compartment Persistent Organic Pollutant Emissions model and inventory: POPE. The model computes temporally and spatially resolved model ready emissions for 23 of the most widely used Per- and Polyfluoroalkyl Substances (PFAS) distinguishing between emissions to air and emissions to water covering the time span from the first industrial scale production in 1950 up until 2020 on an annual basis on a grid with 0.5° resolution. The POPE model distributes estimated total PFAS emissions in space and time based on several data sets such as the E-PRTR, NACE and US-EPA FRS in combination with socio-economic data as population and GDP complemented by estimates for individual point sources, such as industrial sites and airports, whereby the source activity is dependent on regional changes in production volumes, usage quotas, and recapturing efficiency over time. It includes emissions by industrial production, diffuse emissions through usage and disposal of consumer products, secondary emissions from the reaction of precursors, and emissions by firefighting exercises on airports using Aqueous Film Forming Foams. It is demonstrated that the POPE emission inventory is compatible with current global emission estimates, and temporal and spatial variability of the emissions is explored. A comparison of independent measurements with modelled river concentrations based on the POPE emission inventory is provided. The POPE emission inventory is meant to be used as input for atmospheric and marine chemistry transport models, eventually allowing to assess the environmental fate of PFAS. POPE can be used to create hypothetical future emission scenarios, enabling model based predictions which can inform policy decisions. This is important given that even with a theoretical global fade-out of PFAS production, significant legacy pollution is still to be expected.
Surface current variability in the East Australian Current from long-term HF radar observations
Authors: Tran Manh Cuong , Roughan Moninya , Schaeffer Amandine
Published: October 2024

Abstract. The East Australian Current (EAC) exhibits significant variability across a wide range of spatial and temporal scales, from mesoscale eddies and meanders to seasonal, interannual, and decadal fluctuations in its intensity, pathway, and influence on the continental shelf circulation. Understanding and monitoring this variability is crucial because the EAC plays an important role in controlling shelf dynamics, regional circulation, coastal weather and global climate patterns. As such, two high-frequency (HF) coastal radar systems have been deployed on the east coast of Australia to measure surface currents upstream and downstream of the East Australian Current (EAC) separation point. The multi-year radar dataset (spanning 4–8 years) is presented here and its use is demonstrated to assess the spatial and temporal variability of the EAC and the adjacent continental shelf circulation, ranging from seasonal to interannual scales. The dataset is gap-filled using a 2dVar approach (after rigorous comparison with the traditional unweighted Least-squares fit (LS) method). Additionally, we explore the representation depth variability of the observations by comparing the data with surface Lagrangian drifter velocities (with and without depth drogues). The multi-year radar-derived surface current dataset, which was validated using short-term drifter and long-term current meter observations, revealed that the local upstream circulation is strongly dominated by the EAC’s annual cycle, peaking in the austral summer. The analysis using 8 years of upstream data revealed the period of the EAC intensification at around 3–5 years. The interannual variability of the poleward transport downstream was driven by the intrinsic variability of the jet. This dataset which continues to be collected, complemented by numerical simulations and in-situ measurements, will provide a comprehensive view of the EAC’s variability and its impact on the broader regional circulation dynamics which can be used for a range of dynamical investigations.

Abstract. Numerical methods and simulation codes are essential for the advancement of our understanding of complex atmospheric processes. As technology and computer hardware continue to evolve, the development of sophisticated code is vital for accurate and efficient simulations. In this paper, we present the recent advancements made in the FLEXible PARTicle dispersion model (FLEXPART), a Lagrangian particle dispersion model, which has been used in a wide range of atmospheric transport studies over the past 3 decades, extending from tracing radionuclides from the Fukushima nuclear disaster, to inverse modelling of greenhouse gases, and to the study of atmospheric moisture cycles. This version of FLEXPART includes notable improvements in accuracy and computational efficiency. (1) By leveraging the native vertical coordinates of European Centre for Medium Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS) instead of interpolating to terrain-following coordinates, we achieved an improvement in trajectory accuracy, leading to a ∼8 %–10 % reduction in conservation errors for quasi-conservative quantities like potential vorticity. (2) The shape of aerosol particles is now accounted for in the gravitational settling and dry-deposition calculation, increasing the simulation accuracy for non-spherical aerosol particles such as microplastic fibres. (3) Wet deposition has been improved by the introduction of a new below-cloud scheme, by a new cloud identification scheme, and by improving the interpolation of precipitation. (4) Functionality from a separate version of FLEXPART, the FLEXPART CTM (chemical transport model), is implemented, which includes linear chemical reactions. Additionally, the incorporation of Open Multi-Processing parallelisation makes the model better suited for handling large input data. Furthermore, we introduced novel methods for the input and output of particle properties and distributions. Users now have the option to run FLEXPART with more flexible particle input data, providing greater adaptability for specific research scenarios (e.g. effective backward simulations corresponding to satellite retrievals). Finally, a new user manual (https://flexpart.img.univie.ac.at/docs/, last access: 11 September 2024) and restructuring of the source code into modules will serve as a basis for further development.

Abstract. Daily transpiration (Td) is crucial for both irrigation water management and increasing crop water productivity. The use of the remote-sensing-based two-source energy balance model (TSEB) has proven to be robust in estimating plant transpiration and evaporation separately for various crops. However, remote sensing models provide instantaneous estimations, and so daily upscaling approaches are needed to estimate daily fluxes. Daily upscaling methodologies have not yet been examined to upscale solely transpiration in woody crops. In this regard, this study aims to evaluate the proper image acquisition time throughout the day and four methodologies used to retrieve Td in almond trees with different production systems and water statuses. Hourly transpiration (Th) was estimated using the TSEB contextual approach (Th–TSEB) with high-resolution imagery five times during two diurnal courses. The tested methodologies were the following: the simulated evaporative fraction variable (EFsim), irradiance (Rs), reference evapotranspiration (ETo), and potential evapotranspiration (ETp). These approaches were first evaluated with in situ sap flow (T–SF) data and were then applied to the Th–TSEB. Daily T–SF showed significant differences among production systems and levels of water stress. The EFsim and ETp methods correlated better with measured T–SF and reduced the underestimation observed using the Rs and ETo methods, especially at noon in the severely water-stressed trees. However, the daily upscaling approaches applied in the TSEB (Td–TSEB) failed to detect differences between production systems. The lack of sensibility of Th–TSEB among production systems poses a challenge when estimating Td in canopies with discontinuous architectural structures. The use of ETp as a reference variable could address this issue as it incorporates various aerodynamic and radiative properties associated with different canopy architectures that influence the daily Th–SF pattern. However, more accurate ETp estimates or more advanced ETp models are needed.
Modelling hazards impacting the flow regime in the Hranice Karst due to the proposed Skalička Dam
Authors: Spano Miroslav , Riha Jaromir
Published: October 2024

Abstract. This study examines the hydrogeological hazard associated with the construction of the proposed Skalička Dam in the vicinity of the Hranice Karst. Prompted by the catastrophic regional floods in 1997 and 2010, the design of the dam aims to mitigate floods along the Bečva River downstream of the reservoir. However, concerns have been raised regarding the potential disturbance of the natural groundwater regime in the Hranice Karst and the source of mineral waters for the Teplice spa. This is due in particular to the dam's location in an area with limestone outcrops potentially susceptible to surface-water infiltration. Previous studies have also highlighted the strong correlation between the water level in the Bečva River and the water level in karst formations such as the Hranice Abyss, Zbrašov Aragonite Caves, and other caves in the locality. To address these concerns, a nonlinear reservoir-pipe groundwater flow model was employed to simulate the behaviour of the Hranice Karst aquifer and specifically the effects of the dam reservoir's impoundment. The study concluded that the lateral variant of the dam would have a practically negligible impact on the karst water system, with the rise in water level being only a few centimetres. The through-flow variant was found to have a more significant potential impact on water levels and the outflow of mineral water to the spa, with a piezometric rise of about 1 m and an increase in the karst water discharge to the Bečva River of more than 50 %. Based on these results, recommendations for further investigations concerning the design of the dam and its eventual construction have been formulated to reduce geological uncertainties and to minimize the potential impact of the hydraulic scheme on the hydrogeology of the karstic system.
Alkalinity sources in the Dutch Wadden Sea

Abstract. Total alkalinity (TA) is an important chemical property that plays a decisive role in the oceanic buffering capacity with respect to CO2. TA is mainly generated by weathering on land as well as by various anaerobic metabolic processes in the water and sediments. The Wadden Sea, located in the southern North Sea, is hypothesized to be a source of TA for the North Sea, but quantifications are scarce. This study shows observations of TA, dissolved inorganic carbon (DIC), and nutrients in the Dutch Wadden Sea in May 2019. Surface samples were taken along several transects in order to investigate spatial distribution patterns and compare them with data from the late 1980s. A tidal cycle was sampled to further shed light on TA generation and potential TA sources. We identified the Dutch Wadden Sea as a source of TA and estimated an export of 6.6 Mmol TA per tide to the North Sea. TA was generated in the sediments, with deep pore water flow during low tide enriching the surface water. A combination of anaerobic processes and CaCO3 dissolution were potential TA sources in the sediments. We deduce that seasonality and the associated nitrate availability specifically influence TA generation by denitrification, which is low in spring and summer.

Las bibliotecas públicas pueden contribuir positivamente a superar la brecha digital y el sentimiento de exclusión social en personas mayores mediante el diseño y desarrollo de servicios basados en la alfabetización informacional y digital. En este artículo se da a conocer el taller “Mayores Conectados” desarrollado por la Biblioteca Pública Municipal Ángel González de Madrid, basado en la adquisición de competencias para el uso de los smartphones (teléfonos inteligentes). En España y gracias a la revisión de la literatura científica realizada, son varios los estudios donde se habla de una carencia de servicios en bibliotecas para personas mayores, y es esta carencia la que fundamenta la realización del taller y el artículo en sí. Además de su fundamentación, se exponen sus objetivos, su ejecución y el impacto positivo en las personas participantes junto con los reconocimientos alcanzados. La originalidad del artículo radica en que aporta conocimiento para el diseño y desarrollo de servicios en bibliotecas centrados en la brecha digital de las personas mayores, potenciando en ellas también valores sociales como la inclusión, las relaciones con la familia y de amistad.
