Measurement Error Proxy System Models: MEPSM v0.2
Authors: Fischer Matt J.
Published: April 2023

Abstract. Proxy system models (PSMs) are an essential component of paleoclimate data assimilation and for testing climate field reconstruction methods. Generally, current statistical PSMs consider the noise in the output (proxy) variable only, and ignore the noise in the input (environmental) variables. This problem is exacerbated when there are several input variables. Here we develop a new PSM, the Measurement Error Proxy System Model (MEPSM), which includes noise in all variables, including noise auto- and cross-correlation. The MEPSM is calibrated using a quasi-Bayesian solution, which leverages Gaussian conjugacy to produce a fast solution. Another advantage of MEPSM is that the prior can be used to stabilize the solution between an informative prior (e.g. with a non-zero mean) and the maximum likelihood solution. MEPSM is illustrated by calibrating a proxy model for δ18Ocoral with multiple inputs (marine temperature and salinity), including noise in all variables. MEPSM is applicable to many different climate proxies, and will improve our understanding of the effects of predictor noise on PSMs, data assimilation, and climate reconstruction.

Abstract. The region of southern Africa (SAF) is among the most exposed climate change
hotspots and is projected to experience severe impacts across multiple
economical and societal sectors. For this reason, producing reliable
projections of the expected impacts of climate change is key for local
communities. In this work we use an ensemble of 19 regional climate model
(RCM) simulations performed in the context of the Coordinated Regional
Climate Downscaling Experiment (CORDEX) – Africa and a set of 10 global
climate models (GCMs) participating in the Coupled Model Intercomparison
Project Phase 5 (CMIP5) that were used as the driving GCMs in the RCM
simulations. We are concerned about the degree to which RCM simulations are
influenced by their driving GCMs, with regards to monthly precipitation
climatologies, precipitation biases and precipitation change signal,
according to the Representative Concentration Pathway (RCP) 8.5 for the end
of the 21st century. We investigate the degree to which RCMs and GCMs are
able to reproduce specific climatic features over SAF and over three
sub-regions, namely the greater Angola region, the greater Mozambique region,
and the greater South Africa region. We identify that during the beginning
of the rainy season, when regional processes are largely dependent on the
coupling between the surface and the atmosphere, the impact of the driving
GCMs on the RCMs is smaller compared to the core of the rainy season, when
precipitation is mainly controlled by the large-scale circulation. In
addition, we show that RCMs are able to counteract the bias received by
their driving GCMs; hence, we claim that the cascade of uncertainty over SAF
is not additive, but indeed the RCMs do provide improved precipitation
climatologies. The fact that certain bias patterns during the historical
period (1985–2005) identified in GCMs are resolved in RCMs provides
evidence that RCMs are reliable tools for climate change impact studies over
SAF.

Abstract. Parameterized boundary layer turbulence and moist
convection remain some of the largest sources of uncertainty in general
circulation models. High-resolution climate modeling aims to reduce that
uncertainty by explicitly attempting to resolve deep moist convective
motions. An example of such a model is the Simple Cloud-Resolving E3SM
Atmosphere Model (SCREAM) with a target global resolution of 3.25 km,
allowing for a more accurate representation of complex mesoscale deep
convective dynamics. Yet, small-scale planetary boundary layer turbulence
and shallow convection still need to be parameterized, which in SCREAM is
accomplished through the turbulent-kinetic-energy-based (TKE-based) simplified higher-order closure
(SHOC) – a simplified version of the assumed-double-Gaussian-PDF (probability density function)
higher-order-closure method. In this paper, we implement a stochastic-multiplume mass-flux (MF) parameterization of dry and shallow convection in
SCREAM to go beyond the limitations of double-Gaussian-PDF closures and
couple it to SHOC (SHOC+MF). The new parameterization implemented in a
single-column model type version of SCREAM produces results for two shallow
cumulus convection cases (marine and continental shallow convection) that
agree well with the reference data from large-eddy simulations, thus improving the
general representation of the thermodynamic quantities and their turbulent
fluxes as well as cloud macrophysics in the model. Furthermore, SHOC+MF
parameterization shows weak sensitivity to the vertical grid resolution and
model time step.
Effects of complex terrain on the shortwave radiative balance: a sub-grid-scale parameterization for the GFDL Earth System Model version 4.1

Abstract. Parameterizing incident solar radiation over complex topography regions in Earth system models (ESMs) remains a challenging task. In ESMs, downward solar radiative fluxes at the surface are typically computed using plane-parallel radiative transfer schemes, which do not explicitly account for the effects of a three-dimensional topography, such as shading and reflections. To improve the representation of these processes, we introduce and test a parameterization of radiation–topography interactions tailored to the Geophysical Fluid Dynamics Laboratory (GFDL) ESM land model. The approach presented here builds on an existing correction scheme for direct, diffuse, and reflected solar irradiance terms over three-dimensional terrain. Here we combine this correction with a novel hierarchical multivariate clustering algorithm that explicitly describes the spatially varying downward irradiance over mountainous terrain. Based on a high-resolution digital elevation model, this combined method first defines a set of sub-grid land units (“tiles”) by clustering together sites characterized by similar terrain–radiation interactions (e.g., areas with similar slope orientation, terrain, and sky view factors). Then, based on terrain parameters characteristic for each tile, correction terms are computed to account for the effects of local 3D topography on shortwave radiation over each land unit. We develop and test this procedure based on a set of Monte Carlo ray-tracing simulations approximating the true radiative transfer process over three-dimensional topography. Domains located in three distinct geographic regions (Alps, Andes, and Himalaya) are included in this study to allow for independent testing of the methodology over surfaces with differing topographic features. We find that accounting for the sub-grid spatial variability of solar irradiance originating from interactions with complex topography is important as these effects led to significant local differences with respect to the plane-parallel case, as well as with respect to grid-cell-scale average topographic corrections. We further quantify the importance of the topographic correction for a varying number of terrain clusters and for different radiation terms (direct, diffuse, and reflected radiative fluxes) in order to inform the application of this methodology in different ESMs with varying sub-grid tile structure. We find that even a limited number of sub-grid units such as 10 can lead to recovering more than 60 % of the spatial variability of solar irradiance over a mountainous area.
ISAT v2.0: an integrated tool for nested-domain configurations and model-ready emission inventories for WRF-AQM
Authors: Wang Kun , Gao Chao , Wu Kai , Liu Kaiyun , Wang Haofan , Dan Mo , Ji Xiaohui , Tong Qingqing
Published: April 2023

Abstract. The ISAT (Inventory Spatial Allocation Tool) v2.0 is an
integrated tool that has been developed to configure nested domains,
downscale regional emission inventories, allocate local emission
inventories, and generate model-ready emission inventories for the Weather
Research and Forecasting (WRF)–Air Quality Numerical Model (AQM). The tool
consists of four modules, namely “Prepgrid”, “Downscale”, “Mapinv”,
and “Prepmodel”, which are designed to perform specific tasks. The
Prepgrid module utilizes a nested-domain configuration algorithm based
on WRF-AQM nested rules and the target domain shapefile. The Downscale module establishes a “sub-grid nearest” method to downscale the regional
emission inventory based on spatial surrogate, thereby improving the
accuracy and computational efficiency of the process. The Mapinv module
allocates a user-defined regional- and/or city-level emission inventory to grid
level based on the target domain shapefile and the spatial surrogate.
Finally, the Prepmodel module generates the model-ready inventories by
introducing unique user-friendly emission sector IDs using abbreviations and
speciation profiles based on species in the emission inventory and chemical
mechanisms, which is available for both the CMAQ and CAMx models. The ISAT
v2.0 tool provides a user-friendly solution for model users to configure and
run WRF-AQM. And it provides a framework and related algorithms for
researchers to develop similar tools for WRF-AQM.

Abstract. The Atlantic meridional overturning circulation (AMOC) is an important part of our climate system. The AMOC is predicted to weaken under climate change; however, theories suggest that it may have a tipping point beyond which recovery is difficult, hence showing quasi-irreversibility (hysteresis). Although hysteresis has been seen in simple models, it has been difficult to demonstrate in comprehensive global climate models. Here, we outline a set of experiments designed to explore AMOC hysteresis and sensitivity to additional freshwater input as part of the North Atlantic Hosing Model Intercomparison Project (NAHosMIP). These experiments include adding additional freshwater (hosing) for a fixed length of time to examine the rate and mechanisms of AMOC weakening and whether the AMOC subsequently recovers once hosing stops. Initial results are shown from eight climate models participating in the Sixth Coupled Model Intercomparison Project (CMIP6). The AMOC weakens in all models as a result of the freshening, but once the freshening ceases, the AMOC recovers in half of the models, and in the other half it stays in a weakened state. The difference in model behaviour cannot be explained by the ocean model resolution or type nor by details of subgrid-scale parameterisations. Likewise, it cannot be explained by previously proposed properties of the mean climate state such as the strength of the salinity advection feedback. Instead, the AMOC recovery is determined by the climate state reached when hosing stops, with those experiments where the AMOC is weakest not experiencing a recovery.

Published: April 2023

Abstract. The Tropical Andes is a biodiversity hotspot facing pressure from
planned and ongoing hydropower development. However, the effects of dams on
the region's river ecosystems, as mediated by physicochemical changes in the water quality, are poorly known. Colombia is unique among its peers in South America with respect to managing central public environmental databases, including surface water quality data sets associated with the environmental monitoring of dams. To assess the relationship between hydropower and Colombian river conditions, we analyze monitoring data associated with 15 dams, focusing on oxygen availability, thermal regimes and sediment losses because these properties are influenced directly by river damming and impose fundamental constraints on the structure of downstream aquatic ecosystems. We find that most Colombian dams (7 of 10) seasonally reduce concentrations of total suspended solids by large percentages (50 %–99 %) through sediment trapping. Most dams (8 of 15) also, via the discharge of warm reservoir surface waters, seasonally increase river temperatures by 2 to 4 ∘C with respect to upstream conditions. A subset of four dams generate downstream hypoxia
(< 4 mg L−1) and water that is 2 to 5 ∘C colder than inflows, with both processes driven by the turbination and discharge of cold and anoxic hypolimnetic waters during periods of reservoir stratification. Reliance on monitoring data likely leads us to under-detect impacts: many rivers are only sampled once or twice per year, which cannot capture temporal shifts across seasons and days (i.e., in response to hydropeaking). Despite these blind spots, the monitoring data point to some opportunities for planners and hydropower companies to mitigate downstream ecological impacts. These findings highlight the importance of implementing
environmental monitoring schemes associated with hydrologic infrastructure
in developing countries.

Published: April 2023

Abstract. Understanding the past and future evolution of the Antarctic Ice Sheet is
challenged by the availability and quality of observed paleo-boundary
conditions. Numerical ice-sheet models often rely on these paleo-boundary
conditions to guide and evaluate their models' predictions of sea-level
rise, with varying levels of confidence due to the sparsity of existing data
across the ice sheet. A key data source for large-scale reconstruction of
past ice-sheet processes are internal reflecting horizons (IRHs) detected by
radio-echo sounding (RES). When IRHs are isochronal and dated at ice cores,
they can be used to determine paleo-accumulation rates and patterns on
large spatial scales. Using a spatially extensive IRH over the Pine Island
Glacier (PIG), Thwaites Glacier (THW), and the Institute and Möller ice streams (IMIS, covering a total of 610 000 km2 or 30 % of the West Antarctic Ice Sheet (WAIS)), and a local layer approximation model, we infer mid-Holocene accumulation rates over the
slow-flowing parts of these catchments for the past ∼4700 years. By comparing our results with modern climate reanalysis models (1979–2019) and observational syntheses (1651–2010), we estimate that
accumulation rates over the Amundsen–Weddell–Ross Divide were on average
18 % higher during the mid-Holocene than modern rates. However, no
significant spatial changes in the accumulation pattern were observed. The
higher mid-Holocene accumulation-rate estimates match previous
paleo-accumulation estimates from ice-core records and targeted RES surveys
over the ice divide, and they also coincide with periods of grounding-line
readvance during the Holocene over the Weddell and Ross sea sectors. We find
that our spatially extensive, mid-Holocene-to-present accumulation estimates
are consistent with a sustained late-Holocene period of higher accumulation
rates occurring over millennia reconstructed from the WAIS Divide ice core (WD14),
thus indicating that this ice core is spatially representative of the wider
West Antarctic region. We conclude that future regional and continental
ice-sheet modelling studies should base their climatic forcings on
time-varying accumulation rates from the WAIS Divide ice core through the
Holocene to generate more realistic predictions of the West Antarctic Ice
Sheet's past contribution to sea-level rise.
Mechanistic investigations of on-demand light degradable polymeric materials
Authors:   , Bachmann Julian
Published: April 2023

Polymers (colloquially called ‘plastics’) are a unique material class. They critically influenced many aspects of society thanks to their characteristics. Ideally, degradation is desired after usage, but polymers usually lack the feature of ‘on-demand’ degradability. Light would be an ideal trigger medium, given its abundance and control in space and time, thus constituting a suitable stimulus to induce degradation on-demand. In the present thesis, the trigger ‘light’ was explored to provide a powerful tool for on demand degradation scenarios. For this purpose, several polymer model systems were selected, their mechanism of action investigated in detail and probed for degradability.

Published: April 2023

The article presents a review of the results of research on high-entropy alloys, describing the principles of their formation, the basic concepts and properties of high-entropy alloys. The existing categories of the entropic alloys are listed. The effects resulting from the formation of high-entropy alloys are described: high entropy, lattice distortion, sluggish diffusion and cocktail effects. It is noted that the traditional thermodynamic representations for multicomponent alloys require additions. It is also noted that the application of Hume-Rothery rules to predict the phase composition of high-entropy alloys shows some difficulties, since it is difficult to select a large number of elements having the same type of lattice and valence. The results of the analysis of a number of parameters and conditions which, according to the researchers' opinion, affect the structural state created by high-entropy alloys, taking into account which could allow to correctly predict the formation of structures in high-entropy. Analysis of the literature data has shown that at present there is no universal parameter that could allow the correct prediction of the formation of structures in multicomponent alloys systems. Methods for the preparation of powders of high entropy alloys are presented. The results of frequently used methods of obtaining coatings on the basis of high-entropy alloys, such as laser cladding, magnetron sputtering, electrochemical deposition and thermal spraying are reviewed. Disadvantages of obtaining coatings methods are described.

Authors: Hussein Mohsen , Kregar Velikonja Nevenka , Erjavec Karmen
Published: April 2023

Introduction: Integrated clinical pathways should provide the best and most efficient treatment. As no study on barriers to inter-organisational collaboration has investigated the barriers to unimplemented integrated clinical care in a country with less efficiently organised health system, the study aimed to identify these barriers in the preoperative management of patients with hip or knee osteoarthritis in Slovenia.
Methods: A cross-sectional study was conducted using multiple methods, including a quantitative survey with participants involved in target patient groups, and in-depth interviews with involved key actors at micro, meso and macro levels in Slovenia.
Results: Respondents predominantly expressed a lack of inter-organisational collaboration. The exposed barriers are individualistic culture, the level of development of the health system, financing, administration, and regulatory frame at the macro level, shortage of staff at the meso level, and the lack of technological standards, trust, communication, and perception of pressures at the micro level.
Discussion and conclusion: In addition to the barriers identified in previous studies, our study shows that individualistic culture and the level of development of the health system at the macro level, manifested as a pressure on health professionals and other actors at the micro level, are important barriers to inter-organisational collaboration.

Published: April 2023

Cloud computing and 6G networks are in high demand at present due to their appealing features as well as the security of data stored in the cloud. There are various challenging methods that are computationally complicated that can be used in cloud security. Identity-based encryption (IBE) is the most widely used techniques for protecting data transmitted over the cloud. To prevent a malicious attack, it is an access policy that restricts access to legible data to only authorized users. The four stages of IBE are setup, key extraction or generation, decryption and encryption. Key generation is a necessary and time-consuming phase in the creation of a security key. The creation of uncrackable and non-derivable secure keys is a difficult computational and decisional task. In order to prevent user identities from being leaked, even if an opponent or attacker manages to encrypted material or to decode the key this study presents an advanced identity-based encryption technique with an equality test. The results of the experiments demonstrate that the proposed algorithm encrypts and decrypts data faster than the efficient selective-ID secure IBE strategy, a competitive approach. The proposed method's ability to conceal the identity of the user by utilizing the Lagrange coefficient, which is constituted of a polynomial interpolation function, is one of its most significant aspects.

Authors: Liu Muyang
Published: April 2023

In recent years, mental illness has become one of the most prevalent diseases in the world and one of the leading causes of disability and even death among young people between the ages of 15 and 29, most of whom are female college students. As one of the most complicated groups in society, female students are subjected to high levels of questioning and mental stress in their daily study and life, but they are unable to relieve themselves and can only make negative emotions pile up. Most of them report that mental illness not only makes them feel mentally uncomfortable but also affects their physical state and further negatively affects their school life and daily life; long-term use of medication for mental illness can also cause certain side effects. Yoga, on the other hand, as a more gentle sport that focuses on oneself and the combination of mind and body, has fewer side effects compared to drugs and reduces the stress caused by competitiveness than other sports. This paper explores different aspects of the feasibility and appropriateness of yoga as a treatment modality for mental illness among female college students, and results show that yoga practice can be an effective treatment for mental illness with minimal side effects, both in terms of nervous system regulation, physical state enhancement, self-regulation, and suitability for college students. Also, its long-term effect on suppressing negative emotions and stimulating positive emotions is the reason for recommending its use as a treatment method.

In the face of a series of challenges including the Covid-19 pandemic, the energy crisis induced by the Ukraine-Russia war and climate change, professionals in the field of public health and energy must collaborate for the welfare of the aged population in the future.
