Abstract. Δ(17O )measurements of atmospheric CO2 have the potential to be a tracer for gross primary production and stratosphere-troposphere mixing. A positive Δ(17O) originates from intrusions of stratospheric CO2, whereas values close to zero result from equilibration of CO2 and water, predominantly happening inside plants. The stratospheric source of CO2 carrying high Δ(17O) is, however, not well defined in the current models. More and long-time atmospheric measurements are needed to improve this. We present records of the Δ(17O) of atmospheric CO2 conducted with laser absorption spectroscopy, from Lutjewad in the Netherlands (53° 24’N, 6° 21’E) and Mace Head in Ireland (53° 20’ N, 9° 54’ W), covering the period 2017–2022. The records are compared with a 3-D model simulation, and we study potential model improvements. Both records show significant interannual variability, of up to 0.3 ‰. The total range covered by smoothed monthly averages from the Lutjewad record is -0.065 to 0.046 ‰, which is significantly higher than the range of -0.009 and 0.036 ‰ of the model simulation. The 100 hPa 60–90° North monthly mean temperature anomaly was used as a proxy to scale stratospheric downwelling in the model. This strongly improves the correlation coefficient of the simulated and observed year-to-year Δ(17O) variations over the period 2019–2021, from 0.37 to 0.81. As the Δ(17O) of atmospheric CO2 seems to be dominated by stratospheric influx, its use a as a tracer for stratosphere-troposphere exchange should be further investigated.

Abstract. In-situ measurements from IAGOS are used to characterise extreme values of carbon monoxide (CO) in the troposphere between 2002 and 2019. The SOFT-IO model, combining the FLEXPART lagrangian dispersion model with emission inventories over the footprint region is used to identify the origins of the CO in the sampled plumes. The impact of biomass burning and anthropogenic emissions on such CO plumes are characterised through CO mixing ratios and simultaneously recorded ozone (O3) ones. In the Northern Hemisphere, maximum of CO are reached in DJF in the lower troposphere because of the elevated anthropogenic emissions and reduced convective activity of the season. Due to the low photochemistry and the fresh age of the air mass the O3 values of these plumes are low. CO plumes in the upper troposphere result from intense emissions and efficient vertical transport, peaking during JJA. Among the anomalies detected in the UT in JJA, the ones with the higher associated O3 values are the ones associated with biomass burning emissions. The middle troposphere combines the two previous vertical levels with contributions from both local emissions and long-range transport. The emission regimes and meteorological conditions are fundamentally different within the troposphere over Africa. Convection is no longer the limiting factor and the transport of the CO plumes is driven by the ITCZ shift, trade winds and the upper branch of the Hadley cell redistributing the pollution to higher latitudes.

Abstract. In this study, we present and analyze the first continuous timeseries of relevant aerosol precursor vapors from the central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. These precursor vapors include sulfuric acid (SA), methanesulfonic acid (MSA), and iodic acid (IA). We use FLEXPART simulations, inverse modeling, sulfur dioxide (SO2) mixing ratios, and chlorophyll-a (chl-a) observations to interpret the 20 seasonal variability of the vapor concentrations and identify dominant sources. Our results show that both natural and anthropogenic sources are relevant for the concentrations of SA in the Arctic, but anthropogenic sources associated with Arctic haze are the most prevalent. MSA concentrations are an order of magnitude higher during polar day than during polar night due to seasonal changes in biological activity. Peak MSA concentrations were observed in May, which corresponds with the timing of the annual peak in chl-a concentrations north of 75° N. IA concentrations exhibit two distinct peaks during 25 the year: a dominant peak in spring and a secondary peak in autumn, suggesting that seasonal IA concentrations depend on both solar radiation and sea ice conditions. In general, the seasonal cycles of SA, MSA, and IA in the central Arctic Ocean are related to sea ice conditions, and we expect that changes in the Arctic environment will affect the concentrations of these vapors in the future. The magnitude of these changes and the subsequent influence on aerosol processes remains uncertain, highlighting the need for continued observations of these precursor vapors in the Arctic.
Variation of atmospheric 137Cs and possible carriers in aerosol samples obtained in Namie in a heavily contaminated area of Fukushima prefecture in 2019
Authors: Li Huihui , Tang Peng , Kita Kazuyuki
Published: January 2024

Abstract. A lot of radionuclides were released into the environment from Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on March 11, 2011. Because of the long half-life (30.12 years) and high-concentration deposition about 137Cs, the study regarding on the distribution of 137Cs in aerosol samples and the understanding carriers of 137Cs became a hot topic in the recent decade. However, even nine years after FDNPP accident, the explanation for the fluctuations of 137Cs and their carriers in the atmosphere remains elusive. In this study, a small fluctuation within 0.0002 Bqm-3 from January to April and a slightly higher level of atmospheric 137Cs from May to September was still observed in the aerosol samples obtained in Namie in a heavily contaminated area of Fukushima prefecture in 2019. Therefore, new observations, obtaining by fluorescent upright microscope and scanning electron microscopes (SEM) equipped with an energy dispersive X-ray spectrometer (EDS), quantitatively demonstrated that the carriers of 137Cs were the combination of C-particles and Al-particles (Al-particles was dominated with the percentage of 68 %) in early May; meanwhile the predominate carriers of 137Cs were carbonaceous particles with the average percentage of 88 % in late May and September. Significantly, small particles (less than 2 μm) and medium particles (2–8 μm) of carbonaceous particles had a higher level in the aerosol samples of May and September. Specially, little particles (less than 1 μm), bacteria (1–1.8 μm), and spores (1.8–10 μm) had a linear relationship with the distribution of atmospheric 137Cs in the aerosol samples of September. In addition, the temperature and the precipitation were the main impact factors on the distribution of 137Cs and its carriers.
The Geometric Correction Method for zircon (U-Th)/He chronology: correcting systematic error and assigning uncertainties to alpha-ejection corrections and eU concentrations
Authors: Zeigler Spencer D. , Baker Morgan , Metcalf James R. , Flowers Rebecca M.
Published: January 2024

Abstract. The conventional zircon (U-Th)/He (ZHe) method typically uses microscopy measurements of the dated grain together with the assumption that the zircon can be appropriately modeled as a geometrically perfect tetragonal or ellipsoidal prism in the calculation of volume (V), alpha ejection correction (FT), equivalent spherical radius (RFT), effective uranium concentration (eU), and corrected (U-Th)/He date. Here, we develop a set of corrections for systematic error and determine uncertainties to be used in the calculation of the above parameters for zircon, using the same methodology as Zeigler et al. (2023) for apatite. Our approach involved acquiring both “2D” microscopy measurements and high resolution “3D” nano-computed tomography (CT) data for a suite of 223 zircon grains from nine samples showcasing a wide range of morphology, size, age, and lithological source, calculating the V, FT, and RFT values for the 2D and 3D measurements, and comparing the 2D vs. 3D results. We find that the values derived from the 2D microscopy data overestimate the true 3D V, FT, and RFT values for zircon, with one exception (V of ellipsoidal grains). Correction factors for this misestimation determined by regressing the 3D vs. 2D data range from 0.81–1.04 for V, 0.97–1.0 for FT, and 0.92–0.98 for RFT, depending on zircon geometry. Uncertainties (1σ) derived from the scatter of data around the regression line are 13–21 % for V, 5 %–1 % for FT, and 8 % for RFT, again depending on zircon morphologies. Like for apatite, the main control on the magnitude of the corrections and uncertainties is grain geometry, with grain size being a secondary control on FT uncertainty. Propagating these uncertainties into a real dataset (N = 28 ZHe analyses) generates 1σ uncertainties of 12–21 % in eU and 3–7 % in the corrected ZHe date when both analytical and geometric uncertainties are included. Accounting for the geometric corrections and uncertainties is important for appropriately reporting, plotting, and interpreting ZHe data. For both zircon and apatite, the Geometric Correction Method is a practical and straightforward approach for calculating more accurate (U-Th)/He data, and for including geometric uncertainty in eU and date uncertainties.

Abstract. Sea ice is important for both regional and global climate, but comprehensive sea ice records are lacking pre-1978, when global-scale spaceborne observations began. Attempts to reconstruct sea ice conditions in different regions of Antarctica with the help of methane sulphonic acid (MSA) records from ice cores have had varying success, highlighting the often-regional relationship between ice core MSA and sea ice. This study uses MSA records from three firn cores and one ice core drilled on Fimbul Ice Shelf in Dronning Maud Land, East Antarctica, to investigate the relationship to satellite-derived sea ice extent (SIE) in the Southern Ocean. Chlorophyll-a concentrations, serving as a measure of phytoplankton biomass, are correlated to the MSA records to further test the MSA – SIE relationship. The relationship to both SIE and chlorophyll-a differs largely between the different firn and ice core MSA records. We find significant correlations for the MSA records from the two higher accumulation core sites to SIE and chlorophyll-a in the Weddell Sea, Western Pacific Ocean, and Ross Sea Sectors. Furthermore, the use of stacked MSA records introduced significant correlations between MSA from the lower accumulation core sites and SIE. The absence of coherent correlation patterns between the MSA records across the four investigated cores and SIE or chlorophyll-a in the Southern Ocean suggests that the Fimbul Ice Shelf MSA records are not consistent proxies for regional SIE.
On dissipation time scales of the basic second-order moments: the effect on the Energy and Flux-Budget (EFB) turbulence closure for stably stratified turbulence

Published: January 2024

Abstract. The dissipation rates of the basic turbulent second-order moments are the key parameters controlling turbulence energetics and spectra, turbulent fluxes of momentum and heat, and playing a vital role in turbulence modelling. In this paper, we use the results of Direct Numerical Simulations (DNS) to evaluate dissipation rates of the basic turbulent second-order moments and revise the energy and flux-budget turbulence closure model for stably stratified turbulence. We delve into the theoretical implications of this approach and substantiate our closure hypotheses through DNS data. We also show why the concept of down-gradient turbulent transport becomes incomplete when applied to the vertical turbulent flux of potential temperature under very stable stratification. We reveal essential feedback between turbulent kinetic energy, the vertical flux of buoyancy and turbulent potential energy, which is responsible for maintaining shear-produced stably stratified turbulence up to extreme static stability.
Observation-Constrained Kinetic Modelling of Isoprene SOA Formation in the Atmosphere

Published: January 2024

Abstract. Isoprene has the largest global non-methane hydrocarbon emission, and the oxidation of isoprene plays a crucial role in the formation of secondary organic aerosols (SOA). Two primary processes are known to contribute to SOA formation from isoprene oxidation: (1) the reactive uptake of isoprene-derived epoxides on acidic or aqueous particle surfaces and (2) the absorptive gas-particle partitioning of low-volatility oxidation products. In this study, we developed a new multiphase condensed isoprene oxidation mechanism that include these processes with key molecular intermediates and products. The new mechanism was applied to simulate isoprene gas-phase oxidation products and SOA formation from previously published chamber experiments under a variety of conditions and atmospheric observations during the Southern Oxidant and Aerosol Studies (SOAS) field campaign. Our results show that SOA formation from most of the chamber experiments is reasonably reproduced using our mechanism except when the concentration ratios of initial nitric oxide to isoprene exceeds ~2. The SOAS simulations also reasonably agree with the measurements regarding the diurnal pattern and concentrations of different product categories. The molecular compositions of the modelled SOA indicate that multifunctional low-volatility products contribute to isoprene SOA more significantly than previously thought, with a median mass contribution of ~57 % to the total modelled isoprene SOA. This contribution, however, may vary greatly, mainly dependent on the volatility estimation and treatment of particle-phase processes (i.e., photolysis and hydrolysis). Our findings emphasize that the various pathways to produce these low-volatility species should be considered in models to more accurately predict isoprene SOA formation. The new condensed isoprene chemical mechanism can be further incorporated into regional-scale air quality models, such as the Community Multiscale Air Quality Modelling System (CMAQ), to assess isoprene SOA formation on a larger scale.

Authors: Schmid Manuel F. , Giometto Marco G. , Lawrence Gregory A. , Parlange Marc B.
Published: January 2024

Abstract. We present BoundaryLayerDynamics.jl, a new code for turbulence-resolving simulations of atmospheric boundary-layer flows as well as canonical turbulent flows in channel geometries. The code performs direct numerical simulation as well as large-eddy simulation using a hybrid (pseudo)spectral and finite-difference approach with explicit time advancement. Written in Julia, the code strives to be flexible and adaptable without sacrificing performance, and extensive automated tests aim to ensure that the implementation is and remains correct. We show that the simulation results are in agreement with published results and that the performance is on par with an existing Fortran implementation of the same methods.
Conjugate Aurora Observations by the Gjøa and Discovery Expeditions
Authors: Egeland Alv
Published: January 2024

Abstract. During 1901 to 1912 – known as the ‘heroic period’ of Arctic and Antarctic exploration, great inroads were made not only geographic but also scientific to our knowledge of the continent. At Amundsen’s Expedition through the Northwest Passage measurements of the geomagnetic field and visual auroras were carried out for 19 months at Gjøahavn (geographic coordinates 68° 37’ 10’’ North (N); 95° 53’ 25’’West (W). Scott’s Discovery Expedition – at Cape Armitage, McMurdo (coordinates 77.86° S; 166.69° E), Antarctica, carried out same type of measurements. Their observations were carried out geomagnetically conjugate to Gjøahavn. In addition, measurements were overlapping in time during the year 1903–04. However, these two stations are located at different longitudes so there is a difference in local time between the stations of about 6 hours. Gjøahavn and Cape Armitage are conveniently located for separating disturbances in the polar cap regions caused by solar electromagnetic radiations or solar wind. The observations were carried out for seven moths per year. This gave a unique possibility to compare conjugate characteristics of polar cap auroras. Comparing conjugate geophysical data introduce some difficulties. During the winter season at Gjøahavn, they had bright summer in Antarctica, and vis versa. Thus, simultaneous temporal, and spatial ionospheric variations can be marked different. Still, the diurnal and seasonal variations were similar. The quantity of the data from Cape Armitage was larger because there they had continuous watch of the sky. The main findings regarding polar cap auroras are: Low intensity bands – also called streamers, are the dominating form. The number of events in 1903 was nearly twice that in 1902 and 1904. A marked midwinter maximum was observed at both stations. Many displays were observed poleward of the oval. A large fraction was associated with weak magnetic disturbances. The polar cap auroral forms: Theta arcs, poleward moving substorm arcs (PSA), and transpolar arcs (TA), have special geomagnetic signatures, so they can be mapped even if they are not observed visual. According to recent satellite measurements they are probably caused by polar rain and/or photoelectrons.
Application of Advection-Diffusion Equation for Nonlinearly Evolving Precipitation Field
Authors: Ha Ji-Hoon
Published: January 2024

Abstract. Analytic solutions for the Advection-Diffusion equation have been explored in diverse scientific and engineering domains, aiming to understand transport phenomena, including heat and mass diffusion, along with the movement of water resources. Precipitation, a vital component of water resources, presents a modeling challenge due to the complex interplay between advection-diffusion effects and source terms. This study aims to improve the modeling of nonlinearly evolving precipitation fields by specifically addressing advection-diffusion equations with time-varying source terms. Utilizing analytic solutions derived through the integral transform technique, we modeled the time-varying source term and investigated the correlation between advection-diffusion and source term effects. While the growth of the field is mainly influenced by the amplitude, size, and timescale of the source term, it can be modulated by advection and diffusion effects. When the timescale of source injection is significantly shorter than the dynamic scale of the system, advection and diffusion effects become independent of the field growth. Conversely, when the timescale of source term injection is sufficiently long, the system evolution primarily depends on advection and diffusion effects. In turbulent regimes with strong diffusion and weak advection effects, a quasi-equilibrium state between growth and decay can be established by regulating the decay caused by advection. However, in regimes where advection effects are crucial, the decay process predominates over the growth process.

Зернобобовые культуры повреждаются вредителями, начиная с самых ранних стадий
развития и вплоть до уборки. Совокупные потери продукции от вредного воздействия
фитофагов иногда превышают 50–75%, а в некоторых случаях посевы зернобобовых могут
полностью погибать. Кроме непосредственного вреда, фитофаги приносят и косвенный вред,
открывая пути проникновения в растения возбудителей опасных болезней. В то же время
современная сельскохозяйственная наука способна успешно контролировать развитие и
вредоносность фитофагов зернобобовых культур, предотвращать существенные потери урожаев
даже в годы, благоприятные для вредителей, и обеспечивать высокое качество зерновой и
фуражной продукции. Чечевица – признанный лидер среди бобовых культур по содержанию
растительного белка высокого качества с незаменимыми аминокислотами. Она содержит очень
много железа и фосфора. Почвенно-климатические условия Северного Казахстана
благоприятствуют выращиванию чечевицы с высокими товарными качествами, но вредители
приводят к значительному снижению урожая. Реализация потенциала урожайности современных
сортов данной культуры в большой степени зависит от состояния фитосанитарной обстановки
агроценозов. Анализ многолетних данных показывает, что наиболее вредоносными фитофагами
чечевицы в фазу всходов являются проволочники (Elateridae), клубеньковые долгоносики
(Sitona spр.), гороховая тля (Acyrthosiphon pisum Harr.). Поэтому проведение защитных
мероприятий – важная часть агротехники чечевицы. В статье приведены результаты
двухгодичных исследований по разработке основных приемов защиты семян и посевов чечевицы
от основных вредителей в период всходов. Показана эффективность инсектицидных
протравителей в борьбе с данными вредителями.

En el contexto político global contemporáneo, las diversas luchas sociales se están alienando entre sí hasta elpunto de que la ilusión del capitalismo como único sistema socioeconómico posible está difuminando todos los horizontesdel cambio social. En este artículo, trataremos de redefinir las causas comunes de las luchas sociales, demostrando su interseccionalidad e interdependencia. Para ello, nos ocuparemos de una serie de conceptos de la filosofía de Marx. En la introducción, examinaremos la noción de valor, afirmando que la teoría del valor de Marx no es simplemente una teoría laboral del valor, sino que más bien refleja la estructura paralela de la producción y la circulación, cristalizada en la forma de valor última del dinero. Una vez obtenidas estas ideas preliminares, volveremos al fenómeno del trabajo en el capitalismo, para reinterpretar, en la primera sección del artículo, la distinción marxiana entre trabajo productivo e improductivo. A partir de ahí, se darán los primeros ejemplos concretos de la interseccionalidad de las luchas sociales contra la abstracción del capital: a saber, mostrar que las luchas de género y las raciales tienen ciertas causas comunes, enraizadas en la hegemonía gramsciana. En la segunda sección, examinaremos la distinción que Marx establece entre la subsunción formal y la real. Esta última, afirmaremos, es decisiva para entender cómo el capital estructura la cuasi-totalidad de nuestras relaciones sociales. Tras una interpretación de la película Toni Erdmann de Maren Ade, propondremos algunos medios posibles de lucha interseccional contra la subsunción real, que encontrarán su respaldo teórico en el concepto de universales subversivos. Las observaciones finales abordarán la lógica nuclear de la distribución y la acumulación del capital, un síntoma que pervive a lo largo de la historia preservado e impulsado por la omnipresencia de la ideología, y subrayarán de nuevo implícitamente la importancia de la lucha común en el descongelamiento de la emergencia de un nuevo sujeto revolucionario.

The purpose of the study is to assess the effectiveness of state support measures for ethnic Kazakhs living abroad. The main method of evaluation is the analysis of regulatory legal acts of the Republic of Kazakhstan, national programs, strategic plans, reports on science, analytical reports, sociological research. The identified measures operated asynchronously to varying degrees throughout the entire period of Independence of the Republic of Kazakhstan, which was expressed in unstable regulatory support since the 1990s, in the form of a lack of continuity strategy, consistency in the division of responsibility for their implementation. Insufficient application of a systematic approach led to unjustified duplication of state support measures for ethnic Kazakhs living abroad at the stage of their «development». We associate the expectation of synchronization of measures as a factor in improving the effectiveness of their application at a qualitatively new level with the recent official strengthening of the role of the Ministry of Science and Higher Education of the Republic of Kazakhstan due to the inclusion of the Language Policy Committee in its structure

The use of fiber-optic technologies in the conditions of coal industry enterprises is justified, since fiber-optic sensors are the most sensitive, without the influence of an electromagnetic field, explosion-proof, and corrosion resistant. Fiber optic technology has also been introduced in the mining industry to detect deformation, detect underground gases such as methane, and monitor underground. The human factor has an impact on the accuracy of control, it is also necessary to take into account the suddenness of changes in the picture of mountain pressure in certain areas and the formation of emergency-hazardous collapse zones. Long-term observations of the manifestations of rock pressure have shown a rather acute problem of sudden deformation of the support, leading to a significant reduction in its cross-section, respectively, there is a need to develop hardware and software for monitoring rock pressure, which will allow you to get a more accurate tool and, with its initial changes, carry out proactive measures to strengthen the fastening of workings, preventing cases of collapse and deformation of the arch support.. The purpose of this work is to develop a fiber-optic sensor for monitoring the identification of the geotechnical condition and improving the efficiency of monitoring and ensuring the safety of mining operations in high-risk conditions due to a sudden explosion of gas and dust.

The most known and practically used coding/decoding schemes are investigated. The results of the analysis of algorithmic complexity and simulation of the operation of coding schemes for Gaussian channels show that only multi-threshold decoders of convolutional codes outperform all others for all considered block sizes and coding rates. The multithreshold decoder (MTD) is a development of the simplest Messian threshold decoder with an additional difference register added. This decoder allows decoding block and convolutional self-orthogonal codes. The operating principles of convolutional encoders are considered in detail, the characteristics of multithreshold decoders and the Viterbi decoder for convolutional codes are compared. The best self-orthogonal codes for MTD are chosen, the efficiency of MTD in channels with additive white Gaussian noise is studied. An algorithm for increasing the performance of multithreshold decoding (MTD) based on the optimization of the MTD parameters of symbolic self-orthogonal codes is proposed.

Published: January 2024

It has been established that the problem of skip centering relative to the axis of the shaft of pneumatic hoists is solved on the basis of establishing patterns that connect the energy-efficient mode of operation of the guide device with its design parameters and dynamic loads acting on it. The developed and researched model of the skip movement in the systems of the pneumatic lifting plant made it possible to establish the patterns of interaction between the «skip – guiding devices». During the operation of pneumatic hoists, electricity is spent only on lifting the load, and the lowering of the skip occurs without energy consumption under the action of gravity. It was revealed that the maximum dynamic loads on the guiding devices from the side of the skip of the pneumatic hoists during its movement are determined depending on the mass of the loaded skip, the displacement of its center of mass and the dynamic coefficient. The adequacy of the emerging dynamic loads on the directing devices is confirmed by experimental studies of the model of a skip pneumatic hoist. An objective function has been obtained to determine the dynamism coefficient, which determines the energy-efficient mode of operation of the electric drive of the pneumatic hoist and leads to energy saving of the hoist as a whole.

Pores coming to the surface can cause a violation of the tightness of the valve when the valve is closed, as well as be a focus of erosive destruction, especially in conditions of high-speed flows of the medium. Pores also contribute to the corrosive destruction of metals, since under the influence of certain aggressive media, they increase in size and cause a breach of the tightness of the gate. In the presence of carbon dioxide, nitrogen absorption by the weld pool metal increases and the tendency of the deposited metal to form pores decreases. The introduction of carbon dioxide of at least 30% to nitrogen makes it possible to obtain a dense deposited metal due to its better absorption of nitrogen. A significant factor reducing the formation of pores from nitrogen in the deposited metal 10X17H8X5G2T is the content of ferrotitane in the charge of the PP-AN 133 powder wire. The titanium content in the deposited metal should be within 0.2...0.4%. A further increase in the concentration of titanium leads to a deterioration in the formation of the deposited metal and to an increase in the amount of slag on the surface of the deposited layer
