Published: August 2024

Abstract. With dry deposition and below-cloud scavenging, in-cloud scavenging is one of the three components of aerosol transfer from the atmosphere to the ground. There is no experimental validation of in-cloud particle scavenging models for all cloud types that is not impacted by uncertainties concerning below-cloud scavenging. In this article, the choice was made to start with a recognised and validated microphysical cloud formation model (the DEtailed SCAvenging Model, DESCAM) to extract a scheme of aerosol scavenging by clouds, valid for different cloud types. The resulting model works for the two most extreme precipitation clouds: from cumulonimbus to stratus. It is based on data accessible a priori from numerical weather prediction (NWP) outputs, i.e. the intensity of the rain and the relative humidity in the cloud. The diagnostic of the altitude of the cloud base proves to be a key parameter, and accuracy in this regard is vital. This new in-cloud scavenging scheme is intended for use in long-distance (> 100 km) atmospheric transport models (ATMs) or global climate models (GCMs).

Published: August 2024

Abstract. The mineral ardennite-(As), which belongs to the ardennite group, was originally described in the locality of Salmchâteau, Stavelot Massif, Belgium. In the past 10 years, several new samples of ardennites have been found at seven localities of this region, motivating us to reinvestigate the crystal chemistry of the ardennite group. Under the polarizing microscope, most ardennites form lamellae or needles included in quartz veins or constituting the matrix of red Ordovician schists. Electron-microprobe analyses, as well as single-crystal structure refinements, show a homovalent substitution of As5+ by V5+ at the T4 tetrahedral site, leading to a complete solid solution between ardennite-(As) and ardennite-(V). Minor substitutions on that site allow the incorporation of a maximum of 0.28 P5+ atoms per formula unit (apfu) and of less than 0.1 Si4+ pfu, except in a sample from Arbrefontaine, where Si reaches 0.74 apfu. The main substitution mechanism, affecting both the T4 and M3 sites, is T4Si4++
M3(Al,Fe)3+↔T4(As,V,P)5+
+M3Mg2+. Crystal-chemistry calculations indicate a positive correlation between the unit-cell parameters and the (Ca + Mg + Fe) contents of ardennites, as well as a negative correlation between the bond length distortion coefficients at the T4 and M3 sites. The existence of possible Si-rich and P-rich end-members, as well as the nomenclature of the ardennite group in which dewalquite could be revalidated, is discussed.

Abstract. Modeling and predicting changes in the function and structure of the terrestrial biosphere and its feedbacks to climate change strongly depends on our ability to accurately represent interactions of the carbon and water cycles and energy exchange. However, carbon fluxes, hydrological status, and energy exchange simulated by process-based terrestrial ecosystem models are subject to significant uncertainties, largely due to the poorly calibrated parameters. In this work, an adjoint-based data assimilation system (Nanjing University Carbon Assimilation System; NUCAS v1.0) was developed, which is capable of assimilating multiple observations to optimize process parameters of a satellite-data-driven ecosystem model – the Biosphere–atmosphere Exchange Process Simulator (BEPS). Data assimilation experiments were conducted to investigate the robustness of NUCAS and to test the feasibility and applicability of assimilating carbonyl sulfide (COS) fluxes from seven sites to enhance our understanding of stomatal conductance and photosynthesis. Results showed that NUCAS is able to achieve a consistent fit to COS observations across various ecosystems, including evergreen needleleaf forest, deciduous broadleaf forest, C3 grass, and C3 crop. Comparing model simulations with validation datasets, we found that assimilating COS fluxes notably improves the model performance in gross primary productivity and evapotranspiration, with average root-mean-square error (RMSE) reductions of 23.54 % and 16.96 %, respectively. We also showed that NUCAS is capable of constraining parameters through assimilating observations from two sites simultaneously and achieving a good consistency with single-site assimilation. Our results demonstrate that COS can provide constraints on parameters relevant to water, energy, and carbon processes with the data assimilation system and opens new perspectives for better understanding of the ecosystem carbon, water, and energy exchanges.
Analysis of model error in forecast errors of extended atmospheric Lorenz 05 systems and the ECMWF system
Authors: Bednář Hynek , Kantz Holger
Published: August 2024

Abstract. Forecast error growth as a function of lead time of atmospheric phenomena is caused by initial and model errors. When studying the initial error growth, it may turn out that small-scale phenomena, which contribute little to the forecast product, significantly affect the ability to predict this product. The question under investigation is whether omitting these atmospheric phenomena will improve the predictability of the resulting value. The topic is studied in the extended Lorenz (2005) system. This system shows that omitting small spatiotemporal scales that significantly affect prediction ability will reduce predictability more than modeling it. In other words, a system with model error (omitting phenomena) will not improve predictability. A hypothesis explaining and describing this behavior is developed, with the difference between systems (model error) produced at each time step seen as the error of the initial conditions. The resulting model error is then defined as the sum of the increments of the time evolution of the initial conditions so defined. The hypothesis is compared to the fit parameters that define the model error in certain approximations of the average forecast error growth. Parameters are interpreted in this context, and the approximations are used to estimate the errors described in the hypothesis. A method is proposed to distinguish increments of prediction error growth from small-spatiotemporal-scale phenomena and model errors. Results are presented for the error growth of the ECMWF system, where a 40 % reduction in model error between 1987 and 2011 is calculated based on the developed hypothesis, while over the same period the instability (error growth rate) of the system with respect to initial condition errors has grown.
An assessment of equatorial Atlantic interannual variability in Ocean Model Intercomparison Project (OMIP) simulations
Authors: Prigent Arthur , Farneti Riccardo
Published: August 2024

Abstract. The eastern equatorial Atlantic (EEA) seasonal cycle and interannual variability strongly influence the climate of the surrounding continents. It is thus crucial that models used in both climate predictions and future climate projections are able to simulate them accurately. In that context, the EEA monthly climatology and interannual variability are evaluated over the period 1985–2004 for models participating in the Ocean Model Intercomparison Project Phases 1 and 2 (OMIP1 and OMIP2). The main difference between OMIP1 and OMIP2 simulations is their atmospheric forcing: CORE-II and JRA55-do, respectively. Monthly climatologies of the equatorial Atlantic zonal wind, sea level anomaly, and sea surface temperature in OMIP1 and OMIP2 are comparable to reanalysis products. Yet, some discrepancies exist in both OMIP ensembles: the thermocline is too diffusive, and there is a lack of cooling during the development of the Atlantic cold tongue. The EEA interannual sea surface temperature variability during May–June–July in the OMIP1 ensemble mean is found to be 51 % larger (0.62 ± 0.04 °C) than that in the OMIP2 ensemble mean (0.41 ± 0.03 °C). Likewise, the May–June–July interannual sea surface height variability in the EEA is 33 % larger in the OMIP1 ensemble mean (0.02 ± 0.002 m) than in the OMIP2 ensemble mean (0.015 ± 0.002 m). Sensitivity experiments demonstrate that the discrepancies in interannual sea surface temperatures and sea surface height variabilities between OMIP1 and OMIP2 are mainly attributable to their wind forcings and, specifically, to their variability. While the April–May–June zonal wind variability in the western equatorial Atlantic is similar in both forcings, the zonal wind variability peaks in April for JRA55-do and in May for CORE-II.
Layer-optimized synthetic aperture radar processing with a mobile phase-sensitive radar: a proof of concept for detecting the deep englacial stratigraphy of Colle Gnifetti, Switzerland and Italy

Published: August 2024

Abstract. Radio-echo sounding is a standard technique for imaging the englacial stratigraphy of glaciers and ice sheets. In most cases, internal reflection horizons (IRHs) represent former glacier surfaces, comprise information about past accumulation and ice deformation, and enable the linking of ice core chronologies. IRHs in the lower third of the ice column are often difficult to detect or coherently trace. In the polar ice sheets, progress in IRH detection has been made by using multistatic, phase-coherent radars, enabling focused synthetic aperture radar (SAR) processing. However, these radar systems are often not suitable for deployment on mountain glaciers. We present a proof-of-concept study for a lightweight, phase-coherent and ground-based radar system, based on the phase-sensitive radio-echo sounder (pRES). To improve the detectability of IRHs we additionally adapted a layer-optimized SAR processing scheme to this setup. We showcase the system capability at Colle Gnifetti, Switzerland and Italy, where specular reflections are now apparent down to the base of the glacier. Compared to previously deployed impulse radar systems, with the mobile pRES the age of the oldest continuously traceable IRH could be increased from 78±12 to 288±35 a. Corresponding reflection mechanisms for this glacier are linked to stratified acidic impurities which in the upper part were deposited at a higher rate due to increased industrial activity in the area. Possible improvements to the system are discussed. If successfully implemented, these may provide a new way to map the deep internal structure of Colle Gnifetti and other mountain glaciers more extensively in future deployments.

Navigating Space, Place, and Society: A GeoHumanities Perspective on Transgression in Geetanjali Shree’s Tomb of Sand
Authors: Musfira Tayyab  , Ayesha Akram
Published: August 2024

This research explores the social dynamics of space in Geetanjali Shree’s Tomb of Sand (2021), originally published as Ret Samadhi, and translated into English by Daisy Rockwell. Tomb of Sand revolves around Ma, an eighty year old woman, who rises from a deep trance as new and develops a taste for transgression. The objective of this research essay is to evaluate the social implications of animation of places like doors, thresholds, boundaries, and walls in the novel, and to analyse the role of spatial dimension in the transgressive activities of characters. The research is significant in that it highlights the treatment of space as a physical entity that has a cognition of its own. The paper argues that the places in the novel are alive due to their social soul, and they put forth the ideologies and thoughts of the prominent actors who inhabit them. Places, therefore, become indicators of characters’ transgression since they represent the social expectations with regards to gender, age or class. For instance, the door of Bade’s home (in the text under scrutiny) “knows that it must remain open” as he has a responsibility towards every social class as a civil servant. However, the case is different for Beti whose departure from Bade’s home is viewed as a sign of transgression. This research employs the concept of place by Tim Cresswell in his book In Place/ Out of Place: Geography, Ideology and transgression (1996). Appropriating the tools of interpretive phenomenological analysis of the text, the research contributes to the interdisciplinary domain of GeoHumanities.

Adapun pelaksanaan rehabilitasi narkotika yang diatur pada pasal 59 undang-undang nomor 35 tahun 2009 tentang narkotika dengan surat edaran mahkamah agung (SEMA) Nomor 4 tahun 2010 tentang penempatan penyalagunaan, korban penyalahgunaan dan pecandu narkotika ke dalam lembaga rehabilitasi medis dan rehabilitasi sosial. Adanya penempatan yang tidak mendukung bisa lanjut memperburuk kondisi mental dan kesehatan dan akan mengakibatkan pemulihan yang tidak maksimal sekaligus mendapatkan pengetahuan lain di dalam lembaga pemasayarakatan klas IIA Gorontalo (LAPAS). Meskipun telah ada perangkat peraturan yang mengatur tentang rehabilitasi narkotika, namun pelaksanaannya harus diwujudkan secara nyata. Sebab peraturan tersebut tidak dapat dirasakan manfaatnya secara nyata jika tidak ada menggerakannya dan tidak dilakukan secara benar sesuai undang-undang yang berlaku. Metode yang digunakan dalam penelitian ini adalah metode normative-empiris di mana penerapan rehabilitasi sebagai meminimalisasi tindak pidana narkotika yang berdasarkan undang-undang nomor 35 tahun 2009 tentang narkotika. Pengumpulan data dilakukan dengan Teknik studi kepustakaan dan Teknik wawancara.

The Research objective is to analyze the implementation of rehabilitation for narcotics abuse regulated in law 35 of 2009 concerning narcotics. As for the implementation of narcotics rehabilitation regulated in article 59 of law number 35 of 2009 concerning narcotics by the supreme court circular letter (SEMA) Number 4 of 2010 concerning the placement of abusers, victims of abuse and narcotics addicts into medical rehabilitation institutions and social rehabilitation. The existence of an unsupportive placement can further worsen mental and health conditions and will result in recovery that is not optimal as well as obtaining other knowledge in the Class IIA Gorontalo penitentiary (LAPAS). Even though there are regulations that regulate narcotics rehabilitation, their implementation must be realised. Because these regulations cannot be felt in real terms if there is no movement for them and they are not carried out properly according to the applicable law. The method used in this study is a normative-empirical method in which rehabilitation is applied to minimize narcotics crimes based on law number 35 of 2009 concerning narcotics. Data collection was carried out using literature study techniques and interview techniques. The obstacles faced in providing narcotics rehabilitation are that the implementation of narcotics rehabilitation is only carried out in class IIA correctional institutions in the city of Gorontalo.

The cause of the high Covid-19 death rate in Indonesia is because COVID-19 patients experience respiratory problems and there are still many people who do not comply with PPKM rules and the 5M health protocol. The Covid-19 pandemic has had a negative impact on the health, social and economic aspects of society. In the health aspect, one obvious impact is that many people have difficulty filling oxygen cylinders, especially in the East Java area. To overcome this, in July 2021 the provincial government opened free oxygen filling stations in 4 areas, namely Surabaya, Sidoarjo, Gresik, and Malang. This study aims to predict the number of oxygen cylinders that will fill in the future. This research is intended to minimize the shortage or excess stock of oxygen demand. One way of forecasting that can be done is to use the Time Series method, namely ARIMA. It was found that the best model for oxygen fulfillment data had an MSE value of 51.6 with ARIMA (2,1,2). The results of the forecasting show that the oxygen supply in October is almost the same for every day and only depends on fluctuations in the oxygen supply that day.

Penyebab tingginya angka kematian Covid-19 di Indonesia karena pasien COVID-19 mengalami gangguan pernapasan dan masih banyak masyarakat yang belum mematuhi aturan PPKM dan protokol kesehatan 5M. Pandemi Covid-19 telah memberikan dampak negatif pada aspek kesehatan, sosial, dan ekonomi masyarakat. Pada aspek kesehatan, salah satu dampak yang jelas adalah banyak masyarakat kesulitan mengisi tabung oksigen, terutama di wilayah Jawa Timur. Untuk mengatasi hal tersebut, maka pada Juli 2021 pemerintah provinsi membuka stasiun pengisian oksigen gratis di 4 wilayah, yakni Surabaya, Sidoarjo, Gresik, dan Malang. Penelitian ini bertujuan untuk memprediksi jumlah tabung oksigen yang akan melakukan pengisian di masa yang akan datang. Penelitian ini ditujukan untuk meminimalisir kekurangan atau kelebihan stok kebutuhan oksigen. Salah satu cara peramalan yang dapat dilakukan adalah dengan menggunakan metode Time Series yaitu ARIMA. Didapatkan bahwa model terbaik untuk data pemenuhan oksigen memiliki nilai MSE sebesar 51,6 dengan ARIMA (2,1,2). Hasil peramalan didapatkan bahwa suplai oksigen pada bulan oktober hampir sama untuk setiap harinya dan hanya tergantung fluktuasi suplai oksigen hari itu.

The indicator used to measure unemployment is the Open Unemployment Rate (TPT). West Java Province is a high-ranking TPT contributor province and during 2018-2021 is always in the top three compared to other provinces in Indonesia. West Java has a different unemployment rate every year and between districts / cities. Panel data regression is a regression technique that combines time series data and corss section. In estimating panel data regression models, there are three approaches, namely the Commond Effect Model (CEM), Fixed Effect Model (CEM) and Random Effect Model (REM). To choose the best model, it uses three tests, namely the Chow test, the Hausman test and the Lagrange Multiplier test. In this study, regression analysis of panel data was carried out to determine the factors that influence the open unemployment rate in West Java province. The results of the analysis obtained the best model of FEM between individuals and time with an R2  value of 0.9410 or 94.10%. Factors that have a significant effect on the open unemployment rate are the district/city minimum wage, education index and percentage of poor people

Joint life endowment status insurance is insurance that pays out if the participant dies during the policy participant's first death or survives until the conclusion of the insurance period. The purpose of this study is to calculate the amount of joint life endowment status life insurance premium reserves using the New Jersey technique in the CIR model with stochastic interest rates. The CIR model's stochastic interest rate value based on Bank Indonesia interest rates from 2018 to 2022 is 0,075. According to the calculations, the resulting annual premium is lower since the number of individuals who survive is greater than the number of persons who die over the insurance period. Furthermore, the size of the New Jersey premium reserve is zero in the first year and becomes closer to the compensation value as the insurance period proceeds.

Background and Purpose: Liver and kidney injuries pose significant global health risks and are often linked to oxidative stress and inflammation. Thioacetamide (TAA) is a hepatorenal toxin widely used in experimental models. Justicia carnea, has been used traditionally for treating liver disorders and silymarin, a flavonoid complex derived from Silybum marianum, is renowned for its hepatoprotective effects. This study investigated the potential protective effects of aqueous-ethanol leaf extract of J. carnea and silymarin on TAA-induced hepatorenal injury in rats.Methods: Six groups (n=5) of male Wistar rats were used in the experiments. Group A (control) received 10 mL/kg of distilled water; group B was administered TAA at a dosage of 300 mg/kg; group C received TAA (300 mg/kg) along with 50 mg/kg of silymarin; groups D, E, and F were administered 300 mg/kg of TAA and subsequently treated with 200, 400, and 600 mg/kg of the extract, respectively. TAA was administered intraperitoneally while silymarin and the extract were administered orally. Treatment was daily for 14 days after which sera and livers from the rats were assayed for enzymes, albumin, bilirubin, urea, creatinine, electrolytes, and antioxidants.Results: Exposure to TAA significantly elevated liver enzyme markers: alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and bilirubin but reduced albumin levels. TAA exposure also led to increased urea, creatinine, sodium, potassium, and chloride levels and caused a significant decrease in antioxidant enzymes: catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH) but increased malondialdehyde (MDA) levels in liver homogenates. However, treatment with silymarin and doses of extract significantly ameliorated hepatorenal function parameters and improved the antioxidant status of the liver in the experimental animals.Conclusion: These findings suggest that both silymarin and J. carnea aqueous-ethanol extract possess hepatoprotective and renoprotective properties, highlighting their potential as therapeutic agents in the management of hepatorenal injuries.
