Analisis Tekanan Sosial Terhadap Keluarga Tanpa Anak Laki-Laki dalam Tradisi Keturunan Suku Karo di Kabupaten Deli Serdang
Authors: Apri wahyuni Br Sinulingga  , Sudirman
Published: January 2025

The objective of this research is to analyse the social pressures experienced by families without sons in the tradition of descendants of the Karo Tribe in Deli Serdang Regency. The qualitative descriptive method was employed in this research to accurately describe complex social phenomena through in-depth observations and interviews with respondents who are directly involved in the tradition. The findings indicate that this social pressure emanates from two principal sources: the family and the community. The pressure from the family is frequently manifested in the form of encouragement to give birth again, particularly from the nuclear family. This can create high expectations and potentially undermine the husband-wife relationship, as well as damaging the relationship between husband and wife. Meanwhile, social pressure is exerted in the form of expectations regarding the presence of a son and comments that create a psychological burden. The social pressures faced by families without sons in Karo society reflect deep-seated cultural norms and significantly impact emotional well-being and family dynamics.

Published: January 2025

This study examines the lived experiences of affluent parents in Borrowdale West, Harare, whose adolescent children abuse drugs. The research aimed to explore four key aspects: (1) how adolescent drug abuse affects parents’ psychological well-being, (2) its impact on marital and familial relationships, (3) its implications for parents’ societal status, and (4) the coping mechanisms adopted by these parents. A qualitative, phenomenological approach was utilized, employing semi-structured interviews with ten participants selected through snowball sampling. Findings revealed that parents endure significant emotional distress, including guilt, shame, excessive worry, and hopelessness. Marital and familial relationships were often strained, but in some cases, strengthened by shared efforts to tackle the problem. Social perceptions of parents ranged from stigma and judgment to sympathy and understanding. Parents coped using a mix of strategies, such as problem-solving approaches, religious faith, and professional support. Recommendations include the integration of psychiatric nurse support for parents, school-based drug prevention programs, community awareness initiatives to reduce stigma, and further research to examine experiences across diverse socio-economic groups.

Authors: Zulfiqar Ali  , Asim Javed  , Abdus Salam Azad  , Gul Zaman Khan  , Salman Abdul Qayyum  , Atif Nazir et al
Published: January 2025

Objective: This study compares the risk of distal embolization of balloon-tip guide catheters (BGCs) versus non-balloon-tip guide catheters (NBGCs) or Guide sheath in mechanical thrombectomy to treat acute ischemic stroke.
Methodology: This retrospective comparative study analyzed patients treated with mechanical thrombectomy for acute ischemic stroke at Rawalpindi Institute of Cardiology, from July 2022 to November 2023 after ethical approval. Patients were grouped based on balloon-tip guide catheters (BGC) versus non-balloon-tip guide catheters (NBGC) or Guide sheath. The outcome was the distal embolization rates during mechanical thrombectomy for stroke intervention. Statistical analysis was conducted by the Statistical Package for the Social Sciences (SPSS) version 25.
Results: A total of 209 patients were included, with 38 in the Balloon Tip (BGC) group and 171 in the Non-Balloon Tip (NBGC) group or Guide sheath. The age distribution, gender, and number of thrombectomy attempts were comparable between the groups, with no significant differences (p > 0.05). Femoral access was used in almost all cases. The BGC group had a slightly lower rate of distal embolism than NBGC (7.9% vs. 9.4%), but the difference was not statistically significant (p = 0.7767).
Conclusion: This study found no significant difference in distal embolism rates between Balloon Tip and Non-Balloon Tip guide catheters in mechanical thrombectomy for stroke. Despite theoretical advantages, BGCs did not show a clear clinical benefit over NBGCs. Further research is needed to determine the optimal guide catheter choice for improving patient outcomes.

Authors: DA SILVA Isaac Newton Lima , FERNANDES Éder , GONZAGA Henrique
Published: January 2025

Background: This paper presents a straightforward and intuitive method for interactive 3D reconstruction and Direct Linear Transformation (DLT) camera calibration using a single image of a structured scene with known object dimensions. The method relies on manual registration of pairs of points on both the image and the terrain, allowing for precise alignment and calibration. Aim: By utilizing this method, users can easily reconstruct 3D scenes and calibrate cameras without the need for complex algorithms or extensive computational resources. Our approach offers a user-friendly solution for 3D reconstruction and camera calibration, making it accessible to a wider audience and applicable in a range of fields such as computer vision, augmented reality, and virtual reality. Methods: This work primarily focuses on the determination of the projection matrix, which plays a crucial role in mapping 3D points onto a 2D image plane. The projection matrix encapsulates both the intrinsic parameters of the camera (such as focal length and optical center) and the extrinsic parameters (such as camera position and orientation in the world coordinate system). By accurately determining the projection matrix, we can effectively project 3D points onto the 2D image plane, enabling tasks like 3D reconstruction, camera localization, and augmented reality applications. Results: We present experimental results obtained from testing the method on an image of a known object, demonstrating its effectiveness and accuracy in producing realistic 3D reconstructions. Discussion: The method's reliance on manual registration of point pairs allows for precise alignment and calibration without the need for complex algorithms or extensive computational resources. This user-friendly approach makes 3D reconstruction and camera calibration accessible to a wider audience and applicable in various fields. Conclusions: Overall, our approach offers a practical and accessible solution for 3D reconstruction and camera calibration, expanding the potential applications in computer vision, augmented reality, and virtual reality.
Emergent physics

Published: January 2025

In this essay we present a brief critical scrutiny of some popular theoretical models developed by the scientific community within the framework of Fundamental Physics. These models develop the hypothesis that it is possible that current physical laws can be derived or emerge from much more fundamental physical entities than those studied to date, which constitutes another way to achieve the Unification of said laws within a single common conceptual structure.  We expose String-nets of Condensed Matter Physics, Loop Quantum Gravity, Superstrings and Branes, Entropic Gravity, the BCJ model, Stochastic Quantum Mechanics, Matrix Statistical Quantum Mechanics, and AdS/CFT Duality. These models are a small sample of an important trend that is gaining strong momentum within the scientific community.

Authors: Muhwan Hariri Wawan , Lasmi Wardiyah Mia
Published: January 2025

This research is motivated by the issue of religious universities in West Java exposed to radicalism. The purpose of this study was to find indicators of radicalism among students as a measuring tool for potential acts of radicalism among students. The research method used in this research is a qualitative method and a case study with in-depth interviews and participatory radicalism combined with quantitative data to collect data on the magnitude or statistical description of the percentage of students exposed to radicalism. From the results of the research conducted, it was found that the indicators of radicalism can be seen based on the attitude of the tendency to take radical actions based on four things, namely: (1) Intolerance, (2) Fanaticism, (3) Exclusivity, and (4) Revolutionary. The four attitudes show that students with these attitudes are included in the categorization of students who have the potential to act radically. Then the pattern of dissemination can occur through, (1) the spread of radicalism by means of direct meetings. This distribution is done through closed recitations with a limited number of participants. With the aim of conveying doctrine and preventing rejection (refutation) from other people who have wider religious knowledge and can reject the arguments of the proponent of doctrine. (2) Using technology by uploading videos and photos of their activities to invite movements they believe to be the most correct actions. (3) By doing propaganda through the news media which is spread through the telegram. This research has an impact on early detection of attitudes and characteristics of students who have the potential to carry out radical attitudes and actions. Then this research has an impact on strengthening and anticipating the possibility of radical actions in Islamic Religious Colleges in West Java.

Published: January 2025

Preeclampsia, severe preeclampsia, and eclampsia are still a common condition in pregnant women, resulting in adverse outcomes in both the maternal and the fetal. The aim of this study is to describe the neonatal outcomes in women with preeclampsia (PE), severe preeclampsia (SP), and eclampsia (E) at RSUD Dr. Soetomo Surabaya. This research implements a descriptive observational study, utilizing medical records of pregnant women with preeclampsia, severe preeclampsia, and eclampsia, and their neonates at RSUD Dr. Soetomo Surabaya from January to December 2022. A total of 185 pregnant women and 190 neonates were included in this study. Severe preeclampsia has the highest number of incidences (130 out of 185). Mothers with PE mostly have normal birth weight (NBW) neonates (57.9%), while mothers with SP mostly have low birth weight (LBW) neonates (34.3%). Mothers with eclampsia have the same amount of LBW and NBW neonates (33.3%), however, the number of very low birth weight (VLBW) neonates was the highest in mothers with eclampsia (PE: 7.9%; SP: 15.7%; E: 22.2%). A total of 23 cases of intrauterine fetal death (IUFD) were recorded with the most cases seen in mothers with SP (19 out of 23). Of 24 cases of neonatal death, most cases were seen in mothers with SP (22 out of 24). From these results, it can be concluded that between PE, SP, and eclampsia, adverse outcomes were more severe in neonates born from mothers with severe preeclampsia and eclampsia compared to the ones from preeclampsia.

Authors: Aisyah Aisyah , Purnami Nyilo , Dewanti Linda , Badriyah Hanik
Published: January 2025

Background: Tinnitus is defined as a medical condition characterized by the perception of auditory sensations without an external sound source. Tinnitus causes harmful disruptions and ultimately reduces the patient’s quality of life. The frequency and intensity of the tinnitus heard by the patient correlate with the severity of disruption and impairment of quality of life. The relationship between tinnitus frequency and intensity with patient quality of life using the Tinnitus Primary Function Questionnaire (TPFQ) questionnaire has not been reported in Indonesia. Objective: This study aims to prove the relationship between tinnitus sound frequency and intensity with tinnitus sufferers’ quality of life. Method: This study was an observational analytic research design with a retrospective study (cross-sectional study) using medical record data of tinnitus patients at the Audiology Clinic of Unit of Otorhinolaryngology-Head Neck Surgery Department Dr. Soetomo Surabaya Regional General Hospital in the period August 2022 – July 2023. Result: The study subjects were 50 patients, 31 men (62%) and 19 women (38%), aged 18-71 years. Patients with acute complaints duration were 11 people (22%) and chronic 39 people (78%). Most patients’ quality of life disruption was found on the emotional disturbance scale with an average of 52.4% disturbance, 48.6% concentration disturbance scale, 40% hearing disturbance scale, and 33.3% sleep disturbance scale. Tinnitus pitch did not correlate with the 12-item TPFQ score measuring the quality of life (p=0.440). Intensity was associated with the TPFQ 12-item hearing loss subscale score (p=0.001). Conclusion: Loudness of tinnitus correlates with hearing ability.

This case report discusses a 43-year-old male, a known case of Chronic Kidney disease, who developed significant complications after a renal biopsy which was performed to diagnose glomerular disease. The patient presented with severe left flank pain, which was later attributed to a large perinephric hematoma which is one of the expected complications in patients with low eGFR. The large perinephric hematoma necessitated intensive care, pain management, blood transfusions, and multidisciplinary action. This report highlights the challenges in managing post-biopsy complications in high-risk patients and underscores the importance of early recognition, vigilant monitoring, and a collaborative approach to care.
The Relationship Between Obesity and Hypertension in Adolescents
Authors: Nursatriaji Ganang , Rimbun Rimbun , Wulandari Laksmi , Yuliawati Tri Hartini
Published: January 2025

Obesity and hypertension are increasingly prevalent among adolescents, and both conditions are interrelated with significant long-term health consequences. This review examines the relationship between obesity and hypertension in adolescents, synthesizing findings from recent studies. Research indicates that obesity, particularly excessive visceral fat accumulation, leads to increased vascular resistance and activation of the renin-angiotensin-aldosterone system, contributing to elevated blood pressure. Genetic factors, along with insulin resistance and metabolic dysfunctions, further exacerbate the risk of developing hypertension in obese adolescents. Additionally, unhealthy dietary habits and insufficient physical activity are major contributors to obesity, which in turn increases the likelihood of hypertension. Studies have shown that interventions targeting weight reduction through balanced diets and regular physical activity can significantly decrease both obesity and blood pressure in adolescents. Furthermore, hypertension in adolescents linked to obesity can result in long-term cardiovascular diseases, underscoring the importance of early detection and prevention. Effective management strategies, including lifestyle modification and routine monitoring of body mass index (BMI) and blood pressure, are critical in mitigating these health risks. This review emphasizes the need for public health policies promoting preventive measures such as regular screenings and health education to curb obesity and hypertension in adolescents, reducing their burden on public health systems. Future research should focus on evaluating the effectiveness of multifactorial intervention programs and long-term outcomes in managing obesity-induced hypertension in adolescents.

Authors: Wahab Siti Maryam , Ferriastuti Widiana , Widhiyanto Lukas , Hidayati Hanik Badriyah
Published: January 2025

Background: Low back pain (LBP) is defined as a global musculoskeletal problem, considered to have a high risk of disability years. LBP is more likely to affect older populations and women. Lumbar spine X-ray is the most widely used lower back examination as it produces clear images of the vertebral structure. One that has become the gold standard is measuring the Ferguson angle in lateral projection on lumbar spine X-rays. Measuring the angle in the lumbosacral is one of the determining parameters in evaluating the possible causes of LBP, one of which uses the Ferguson technique. Objective: To decide the relationship between age and gender with Ferguson angle in LBP patients at Dr. Soetomo General Hospital in January-December 2023. Method: This study is an observational analytical research conducted using a retrospective approach. Results: Overall a total of 164 samples met the inclusion and exclusion criteria. Most LBP sufferers were in the late adult age group (46-65 years), with a total of 74 patients (45.1%), and women predominating at 117 patients (71.3%). Spearman’s analysis showed a very weak, insignificant correlation between age and Ferguson angle (r = 0.042, p = 0.567). Chi-square analysis found no significant relationship between gender and Ferguson angle (p > 0.05).
Sleep Disorders as a Risk Factor for Diabetes or Complications: A Literature Review
Authors: Sauqin Adilla Fida , Atika Atika
Published: January 2025

Sleep disorders are a common health problem that can affect various aspects of the body’s metabolism, including the risk of diabetes mellitus (DM) and its complications. Research shows that poor sleep quality or inadequate sleep duration can increase the risk of developing type 2 DM as well as worsen the condition of patients who have already been diagnosed. The mechanisms involved include impaired glucose regulation, insulin resistance and systemic inflammation. In addition, sleep disorders such as obstructive sleep apnea (OSA), insomnia, and restless legs syndrome also contribute to the development of chronic complications of DM, such as cardiovascular disease and diabetic neuropathy. This literature review aims to identify the relationship between sleep disorders and the risk of diabetes or its complications based on current scientific evidence. The analysis showed a significant association between poor sleep quality and increased risk of DM and long-term complications. Understanding this association allows for more effective prevention and intervention measures, such as raising awareness of the importance of sleep management in high-risk populations. Further research is needed to strengthen these findings and explore more in-depth mechanisms so that optimal prevention and treatment strategies can be developed. Sleep health awareness should be an integral part of diabetes management to improve patients’ quality of life.

Authors: Addimaysqi Rafi , Hidayati Hanik Badriyah , Kusumawardani Martha Kurnia , Widhiyanto Lukas , Atikah Atikah
Published: January 2025

Background: Low back pain (LBP) is a condition with a high incidence across all age groups, particularly among college students and young adults. LBP ranks as the sixth most common symptom globally. Studies in 2022 have shown that adolescents have a notably high incidence rate of 71,2%. Standing posture is particularly problematic among students, with a 2017 study indicating that 68% of students exhibit abnormalities in their standing posture. Objective: To examine the correlation between the severity of LBP and standing posture among medical students at Universitas Airlangga, Surabaya, Indonesia. Method: This research was conducted using an analytical cross-sectional study design. Primary data were collected using a sample that fulfilled inclusion and exclusion criteria with a questionnaire and direct examination. Result: 62 samples of students have been collected. The data revealed that 52 subjects (83%) exhibited postural abnormalities, while 10 subjects (17%) had normal postures. Specific abnormalities, such as shoulder deviation (45 subjects) and forward head position (11 subjects), were identified in the majority of subjects. Conclusion: The results of the study revealed the relationship between standing posture and the severity of low back pain with a p-value of 0.053, This indicates that there is no difference in the severity of low back pain between subjects with normal and abnormal standing posture. A study in 2021 stated that standing posture as a risk factor cannot independently or directly correlate with LBP. Therefore, additional supporting data are necessary to establish significance.

Authors: Kotykova Olena , Babych Mykola , Pohorielova Olena , Nadvynychnyy Sergiy
Published: January 2025

Purpose. The purpose of this study is to assess the economic losses incurred by Ukraine’s livestock production sector due to the war in 2022. The research focuses on quantifying the scale of food losses and evaluating their economic impact.
Methodology. The study uses a comprehensive methodological framework developed by the Kyiv School of Economics (KSE). Economic losses were calculated using both national average and regional pricing approaches. The analysis focuses on losses of cattle, pigs, poultry, and other livestock, as well as milk and eggs.
Results. The study found that the largest economic losses in Ukraine’s livestock production sector in 2022 were concentrated in regions directly impacted by military actions, including frontline areas and territories temporarily occupied by the Russian Federation. Donetsk, Kherson, Zaporizhzhia, and Kharkiv regions suffered the greatest losses. Total economic damages from livestock production losses amounted to over 785.6 million euros based on regional prices and 800.9 million euros based on national prices. While regional price variations and productivity differences played a role in the overall economic losses, the primary driver of these losses was the direct impact of the war on livestock farming in affected area. The findings aim to contribute to the broader discussions regarding reparations and post-war agricultural recovery efforts.
Originality. This study offers a novel approach by focusing specifically on war-induced food losses in the livestock sector and assessing both direct and indirect economic impacts. The use of both national and regional pricing provides a more accurate estimate of economic losses, highlighting the regional disparities caused by the conflict. The findings contribute new insights into the economic repercussions of war on agricultural productivity and food security.
Practical value. The results of this study are important for policymakers and international organisations working in the field of post-war reconstruction and reparations. A quantitative assessment of economic losses can serve as a basis for developing recovery strategies, allocating aid, and prioritising investments in the agricultural sector. Moreover, the research highlights the need for region-specific approaches to effectively address the unique challenges faced by each affected area.

Authors: Boiko Vitalii , Lyzak Mykhailo , Vasyltsiv Taras , Lupak Ruslan , Ohinok Solomiia
Published: January 2025

Purpose. The article aims to develop theoretical and applied foundations for forming a methodology to evaluate financial and economic performance of agricultural enterprises.
Methodology / approach. The authors’ methodology for analysing enterprises’ financial and economic performance is formed in the research. This methodology is based on the use of the principal component analysis. Its use involves the composition of a series of empirical indicators of financial and economic performance based on a temporal approach, the calculation of coefficients of significance of indicators and components, and the calculation of combined and integral indicators of financial and economic performance. The developed methodology was tested using the example of 13 agricultural enterprises. The selected enterprises operate in the Lviv region of Ukraine. The study period covers the operational indicators of agricultural enterprises from 2017 to 2022. The Principal Component Analysis (PCA) method was employed to calculate the integral index of financial and economic performance for these agricultural enterprises. Econometric modeling was applied to identify the key determinants influencing the formation of this integral index.
Results. The research results showed that despite the availability of resource capacities of agricultural enterprises, the process of forming their financial and economic performance is subject to the destabilising influence of war and market factors. The integral index of agricultural enterprises’ financial and economic performance has significantly impacted their operational efficiency. Through the application of econometric modelling, the primary determinants influencing the formation of this integral index of financial and economic performance in agricultural enterprises have been identified. To improve the financial and economic performance of farming enterprises, a targeted mechanism is developed that is aggregated from such strategic areas as the rationalisation of production costs, the improvement of financial and economic management, better budgeting, the development of management personnel, and the restructuring of market policy.
Originality / scientific novelty. The originality of research lies in developing a methodology for assessing enterprises’ financial and economic performance using key indicators and components. This methodology creates an adequate information and analytical basis for improving the management of financial and monetary resources.
Practical value / implications. The practical significance of the research results consists in the possibility of their application in the economic activity of agricultural enterprises to improve the process of forming the financial and economic performance of the latter.

Published: January 2025

Purpose. The aim of our study is to assess the prospects for tourism development and highlight the effectiveness of digital influencers as an e-promotional tool for tourist destinations in Algeria.
Results. Based on the results obtained in the study, we conclude that digital influencers in general and e-word of mouth and social media in particular are important in influencing the followers’ consumption decisions and increasing the travel intentions of Internet users. Furthermore, the study concludes with findings that the relevant ministries should ensure support to tourism content creators, because they provide details of tourism services in publications of professional photography and video making, such services constitute a kind of effective tourism promotion proposed as a solution to revitalise tourism in Algeria.
Scientific novelty. The scientific novelty of this study lies in filling the gap in previous literature and contributing to the field of e-tourism and digital influencers, both theoretically and methodologically. Previous studies have only highlighted certain aspects of tourism and social media’s role in promoting tourism, but none have comprehensively explored the topic by examining and analysing Facebook pages of digital influencers, who publish tourism content and their role in promoting tourism destinations. Previous studies have explored this topic in a general sense, but none have focused on this specific aspect.
Practical value. The practical value of this research is that scientists, tourist accommodations facilities and state institutions, as well as all stakeholders involved in the tourism business, can use it. In addition, the results of the study can be used as a source and tool for the prosperity of the tourism sector in Algeria.

Бұл процестің маңызды бөлігі-адамдардың жұмыс істеу, үйрену, сауда жасау және қарым-қатынас жасау тәсілін түбегейлі өзгерткен мобильді қосымшалар болып табылады. Қазір мобильді қосымшалар байланыс, ойын-сауық, бизнес, білім беру және басқа да қызметтерге қол жеткізу үшін таптырмас құралға айналды. Пайдаланушылар санының өсуіне және қосымшалардағы функционалдылықтың артуына байланысты өнімділік пен ауқымдылығын арттыруға деген қажеттілік туындайды. Бұл мәселеде архитектуралық паттерндер маңызды рөл ойнайды, себебі олар қосымшаның бөліктері өзара қалай әрекеттесетінін және сыртқы жүйелермен қалай байланысатынын анықтайды.

Abstract. This study evaluated the effects of two phytogenic blends on broiler performance, intestinal histomorphology, CD4+ (cluster of differentiation) and CD8+ T-cell numbers, and mRNA abundances of several cytokines in broilers. For this purpose, a total of 300 Ross 308 male broiler chicks that were 1 d old were randomly allocated to five experimental groups. The control group was fed a basal diet without any additives, and there were two phytogenic supplement groups (blend A, mainly comprising extracts of Thymus vulgaris and Filipendula ulmaria, and blend B, consisting of Ginkgo
biloba and Silybum marianum) with two dosage regimens each (100 and 200 mg kg−1 (denoted A100 and A200) and 100 and 300 mg kg−1 (B100 and B300) of the diet, respectively). Over the total growing period, body weight gain and feed intake were unchanged among the groups, although phytogenic blend B showed a dose-dependent improvement in feed conversion ratio. Both phytogenic blends did not affect carcass characteristics. Jejunal morphology (villus height, crypt depth, and their ratio) was modified depending on both the composition and the dosage levels of the selected phytogenics. Also, both phytogenic blends linearly increased the CD4+ and CD8+ T-cell numbers in the jejunum. Moreover, no major treatment effects were observed on mRNA abundances of cytokines (IL-1β, IL-6, and TNFα). However, across the two phytogenic additives employed, a positive linear dose response in IL-1β abundance was noted on day 21 in broilers fed phytogenic blend B. Overall, dietary phytogenic blend B improved the intestinal health and growth performance of chickens compared to blend A. Further studies are suggested to elucidate the effects of the tested phytogenic blends on gut microbiome and on oxidative stress in broiler chickens.
Investigating the role of gravity waves in mesosphere and lower-thermosphere (MLT) inversions at low latitudes

Abstract. The mesosphere and lower-thermosphere (MLT) transitional region, encompassing a height range of 60–100 km, is a distinct and highly turbulent zone within Earth's atmosphere. The region is significant owing to dynamics of atmospheric processes like planetary, tidal, and particularly gravity waves, which contribute to the formation of the mesospheric inversion layer (MIL). Investigating these inversion phenomena is crucial for understanding the dynamics of the middle and upper atmosphere, especially regarding stability and energy transfer. These phenomena are associated with energy transfer processes vital for understanding the overall dynamics of the atmosphere. Despite extensive studies on inversions, the formation mechanisms of mesospheric inversions remain poorly understood. Here, upper and lower inversion phenomena and their causative mechanisms are explored. The study utilizes long-term SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) observations during 2005–2020 over the latitudinal, 3–15° N, and longitudinal, 33–48° E, ranges. The results show that the upper inversion occurs more frequently, with a frequency below 40 %, compared to the lower inversion, which occurs below 20 %. The upper inversion occurs within the height range of 78–91 km, with an inversion amplitude of approximately 20–80 K and a thickness of around 3–12 km. In contrast, the lower inversion is confined to the height range of 70–80 km, with an inversion amplitude of about 10–60 K and a thickness of around 4–10 km. Moreover, the gravity wave indicator potential energy shows high energy (below 100 J kg−1) in the upper-MLT region (85–90 km) compared to the lower-MLT region (70–75 km), with less than 50 J kg−1. Considering gravity waves, the Brunt–Väisälä frequency (N2) stability criteria indicate instability in the upper-MLT region, with very low values compared to the lower-MLT region. This suggests that the high amount of gravity wave potential energy is a consequence of the higher instability in the upper inversion compared to the lower inversion.

Abstract. Accurate national scale greenhouse gas source and sink estimates are essential to track climate mitigation efforts. Inverse models can complement inventory-based approaches for emissions reporting by providing independent estimates underpinned by atmospheric measurements, yet few nations have developed this capability for carbon dioxide (CO2). We present results from a decade-long (2011–2020) national inverse modelling study for New Zealand, which suggests a persistent carbon sink in New Zealand’s terrestrial biosphere (-171 ± 29 Tg CO2 yr−1). This sink is larger than expected from either New Zealand’s Greenhouse Gas Inventory (-24 Tg CO2 yr−1) or prior terrestrial biosphere model estimates (-118 ± 22 Tg CO2 yr−1, Biome-BGCMuSo and CenW). The largest differences are in New Zealand’s South Island, in regions dominated by mature indigenous forests, generally considered to be near equilibrium, and certain grazed pasture regions. Relative to prior estimates, the inversion points to a reduced net CO2 flux to the atmosphere during the autumn/winter period. The overall findings of this study are robust with respect to extensive tests to assess the potential biases in the inverse model due to transport error, prior biosphere, ocean and fossil-fuel estimates, background CO2 and diurnal cycles. We have identified CO2 exchange processes that could contribute to the gap between the inverse, prior and inventory estimates, but the magnitude of the fluxes from these processes cannot entirely explain the differences. Further work to identify the cause for the gap is essential to understand the implications of this finding for New Zealand’s inventory and climate mitigation strategies.
