Abstract
Calibration of satellite observations is crucial for ensuring the quality of retrieved products essential for meteorological and climate applications. Calibration is obtained and monitored through a cascade of stages, including postlaunch vicarious calibration/validation activities through comparison with independent reference measurements. Here, the vicarious calibration method using radiative transfer simulations based on reference radiosondes is considered in the framework of the calibration/validation activities for the Microwave Imager (MWI) and the Ice Cloud Imager (ICI) to be launched with the Second Generation of the EUMETSAT Polar System. This paper presents an overview of the uncertainty characterizing the vicarious calibration of MWI and ICI using radiosondes as performed within the EUMETSAT-funded VICIRS study. The uncertainty characterization is pursued following a metrological approach, providing a preliminary estimation of all the identified sources. The same approach is used to develop a rigorous method for estimating the number of comparison pairs (i.e., observations vs. simulations) needed to reach a certain level of accuracy in bias determination.

Published: August 2024

AbstractAgriculture and climate change are inextricably linked in various aspects. Droughts have become more frequent as a result of climate change, having a significant impact on crop productivity. As a result, the current study investigated the effect of seed priming with natural plant extract and biosynthesized nano plant extract as an environmentally friendly tool for mitigating the drought effect on wheat as an economic crop. The study investigates the biosynthesis of Ag-nano particles from extracts of Marrubium alysson and Torilis arvensis. The UV–Vis spectrophotometer was used to characterize the biosynthesized AgNPs. Wheat grains were primed with Marrubium alysson and Torilis arvensis, along with their nanoextracts, and grown in different water regimes (100%, 60% and 40% field capacity), as well as hydropriming. Leaves were collected to determine the photosynthetic pigments, phenolics, flavonoids, CAT, GPX, H2O2, MDA, soluble sugars, and soluble proteins. In comparison with hydropriming seeds, the study discovered that natural and nano extracts significantly increased the CAT and GPX, as well as soluble proteins. Phenolics, flavonoids, soluble sugars, H2O2, and MDA content all decreased significantly, but pigment content remained unchanged. The study believed that priming wheat with natural and nano extracts, improved drought tolerance through the use of their metabolites, which included soluble sugars, phenolics, and flavonoids, accumulating in other metabolites like lignin, starch, and flavolignan to increase plant tolerance and reduce oxidative damage. Furthermore, nano extracts of Torilis arvensis and Marrubium alysson may be more effective than plant extracts since they separate from each other in PCA analysis.

Abstract
Purpose
TransCelerate BioPharma surveyed its member biopharmaceutical companies to understand current practices and identify opportunities to complement safety signal assessment with rapid real-world data (RWD) analysis.

Methods
A voluntary 30-question questionnaire regarding the use of RWD in safety signal assessment was disseminated to subject matter experts at all TransCelerate member companies in July 2022. Responses were blinded, aggregated, summarized, and presented.

Results
Eighteen of 20 member companies provided responses to the questionnaire. Sixteen (89%) companies reported actively leveraging RWD in their signal assessment processes. Of 18 respondent companies, 8 (44%) routinely use rapid approaches to RWD analysis, 7 (39%) utilize rapid RWD analysis non-routinely or in a pilot setting, 2 (11%) are considering using rapid RWD analysis, and 1 (6%) has no plans to use rapid RWD analysis for their signal assessment. Most companies reported that RWD adds context to and improves quality of signal assessments. To conduct RWD analysis for signal assessment, 16 of 17 (94%) respondent companies utilize or plan to utilize internally available data, 8 (47%) utilize both internal and external data, and 3 (18%) utilize data networks. Respondents identified key challenges to rapidly performing RWD analyses, including data access/availability, time for analysis execution, and uncertainties regarding acceptance of minimal or non-protocolized approaches by health authorities.

Conclusion
Biopharmaceutical companies reported that they see value in the use of rapid RWD analyses for complementing signal assessments. Future work is recommended to offer a framework and process for use of rapid use of RWD analyses in signal assessment.

Published: August 2024

Abstract
Purpose
The purpose of this study was to perform a targeted needs assessment of surgical oncology stakeholders engaged in surgical education of students and trainees. The aim was to determine the appropriate elements of a formal curriculum to be administered to students and residents rotating in the outpatient surgical oncology setting.

Methods
A 10-min survey was sent to surgical oncologists around the country that are a part of the Society of Surgical Oncology (SSO). Data obtained from this survey were analyzed to distinctly identify limitations to education in Surgical Oncology and will allow us to determine which educational goals to prioritize in a curriculum.

Results
189 responses to the needs assessment were received (7% response rate). Most surgeons were in academic practice (77%) and felt that trainees were not fully prepared for an outpatient clinic (57%) and did endorse the need for a curriculum (74%). Barriers identified to teaching and learning included time, abbreviated contact with learners and the volume of patients. Higher yield topics to be included in a future curriculum were identified. More than half of respondents felt that a curriculum could improve feedback, NBME Surgery Subject Exam scores, resident ABSITE scores and patient comfort.

Conclusions
This study represents a novel effort in assessing the unique needs of surgical oncologists within the outpatient learning environment. Building upon the insights gleaned from our survey, the next phase will entail conducting focus groups with respondents to delve deeper into the intricacies of designing an outpatient surgical oncology clinical curriculum tailored for medical students and junior residents. By fostering collaborative discussions among stakeholders, we aim to refine curriculum components in an iterative process and address identified gaps in educational resources and ultimately improve the quality of patient care in the outpatient setting.

Published: August 2024

AbstractDigital import trade is of great practical significance for enhancing the export performance of enterprises and preventing external shocks. This paper empirically examines the impact and mechanism of industrial robot imports on Chinese firms’ export performance based on Chinese microenterprise data from 2004 to 2014. The study shows that the application of imported robots can significantly improve firms’ export performance, and this conclusion still holds after a series of robustness tests. Heterogeneity analysis shows that imported robots have a more significant role in boosting the export performance of state-owned enterprises and enterprises in capital- and technology-intensive industries; at the same time, they have a significant effect on the export performance of enterprises in different modes of trade; and they have a significant role in boosting the export performance of enterprises in eastern China compared with those in central and western regions. Mechanism analysis shows that the enhancement of export performance of enterprises by imported robots is mainly realized by promoting enterprise productivity and human capital efficiency. The policy implication of this paper is that in the era of digital trade, Chinese enterprises should fully utilize the import of digital products to enhance their productivity and promote the high-quality development of foreign trade.

AbstractIn Bangladesh, okra is an important popular summer vegetable. However, traditional farming practices often lead to suboptimal yields. Thus, the study was designed to determine the ideal GA3 and NAA doses for accelerating okra growth, yield, and quality characteristics. A three-replication, randomized complete block design was adopted. Foliar sprays with three concentrations of GA3 (0 ppm, 150 ppm, and 250 ppm) and NAA (0 ppm, 150 ppm, and 250 ppm) were applied in 2022 and 2023. In comparison to the control, the combined application of GA3 @ 150 ppm and NAA @ 150 ppm improved plant height, leaf number, leaf area, branch number, internode length, bud number, pod number, pod length, pod diameter, and 1000 seed weight average over the two years. Furthermore, GA3 @ 150 ppm with NAA 150 ppm increased yield by 35.08% and 27.01% in 2022 and 2023 respectively, above the control. Combining NAA @ 150 ppm with GA3 resulted in higher levels of vitamin C, TSS, magnesium, and zinc by 19.31%, 81.2%, 22.73% and 21.43% in 2022 and 22.83%, 50.57%, 18.07%, 33.33% in 2023 respectively, compared to the control. In contrast, GA3 and NAA decreased potassium and calcium in both year when compared to the control. Overall, the results of this experiment indicated that using GA3 @ 150 ppm with NAA @ 150 ppm could enhance okra growth, yield, and quality. These findings provide insightful information for improving okra cultivation techniques and improving Bangladesh’s productivity in agriculture and food security.
Grain amaranth: A versatile untapped climate-smart crop for enhancing food and nutritional security
Authors: Mukuwapasi Betty , Mavengahama Sydney , Gerrano Abe Shegro 
Published: August 2024

AbstractGlobally, food and nutritional state are marked by an acute prevalence of undernourishment, leading to malnutrition, starvation, and poverty. This state has remained vital for the past years, making attaining zero hunger for the anticipated period (2030) in Africa less possible. To alleviate this challenge, more sustainable food production systems, policy frameworks, mindset changes, and diversification of the food production systems must include some highly nutritious underutilized orphan crops. Acknowledging the potential of untapped, versatile, and climate resilience, Amaranthus significantly promotes sustainable and nutrient-rich food systems. Amaranth grain is a pseudocereal with 4 g of protein and 19 g of carbohydrates per 100 g of cooked amaranth. It is a nutrient powerhouse constituting valuable nutraceuticals, protein, and carbohydrates. Grain amaranth yield ranges from 1500 to 7200 kg/ha. Yield variableness of grain amaranth, lays openings for scientists and researchers to study crop improvement and access a rich pool of genetic materials. These attributes make Amaranthus (amaranth) the most suitable crop candidate in these climate change scenarios. The Amaranthus spp. are popularly known as weedy species and largely undomesticated crops with good adaptability to various geographical locations. Despite its good adaptability, it is less known, under-exploited, and less popular as human food, and its production is very scanty, especially in southern Africa. Efforts are needed to promote its adoption and commercialization. The authors searched pieces of literature in books, journals, and conference papers to establish the potential usage of Amaranthus, its nutritional composition, and its production practices.
Distributed state estimation with compressed and synchronized auxiliary particle filters using graph theory
Authors: Maghsudlu Iman , Danaee M. R. , Arezumand Hamid 
Published: August 2024

AbstractIn this paper, we propose a novel compressed distributed auxiliary particle filter that uses graph theory (CDAPF-GT) to reduce the communication cost and improve the estimation accuracy of a nonlinear state space model. Our method compresses the global loglikelihood function into a set of parameters that are updated by an average consensus algorithm over a network of nodes. Unlike the existing methods, our method synchronizes the particle sets among all the nodes and uses the latest measurements to construct a better proposal distribution. Our method is suitable for applications that require fast and reliable distributed state estimation. We show through various simulation scenarios that our method outperforms the common counterpart method in terms of estimation accuracy with the same level of communication.

Simulation of Water Isotopes in Combustion‐Derived Vapor Emissions in Winter
Authors: Yang Yan , Yoshimura Kei 
Published: August 2024

AbstractWith urbanization, anthropogenic water vapor emissions have become a significant component of the urban atmosphere. Fossil fuel combustion‐derived vapor (CDV) is a primary source of these emissions. Owing to the notably low CDV d‐excess, stable hydrogen and oxygen isotopes are promising for distinguishing CDV from natural sources. Considering the limitations of in situ observations, this study aims to explore the feasibility of using IsoRSM, an isotopically enabled regional atmospheric model, to simulate CDV emissions in urban areas in winter. Two experiments were conducted: one in Salt Lake City (SLC) in January 2017 and another in Beijing in January 2007. The simulation results showed that the CDV addition significantly reduced the water vapor d‐excess, particularly when the boundary layer was stable. The simulation with CDV emissions aligned better with the time series of in situ observations in SLC. The modification led to a more pronounced positive correlation between vapor d‐excess and specific humidity, which was similar to the observation of SLC. The CDV inclusion significantly increased the vapor d‐excess variability with varying wind directions in both sites. However, in Beijing, the underestimation of d‐excess variation from natural sources caused a bigger discrepancy between the observed and simulated d‐excess and CDV fraction. Thus, though there were still biases, the inclusion of CDV could improve the accuracy of isotopic simulation in the urban regions where CDV was one of the controlling factors of vapor d‐excess.
Hot Tropical Temperatures During the Paleocene‐Eocene Thermal Maximum Revealed by Paired In Situ δ13C and Mg/Ca Measurements on Individual Planktic Foraminifer Shells
Authors: Kozdon Reinhard , Kelly D. Clay 
Published: August 2024

AbstractThe Paleocene‐Eocene thermal maximum (PETM, 56 Ma) is an ancient global warming event closely coupled to the release of massive amounts of 13C‐depleted carbon into the ocean‐atmosphere system, making it an informative analogue for future climate change. However, uncertainty still exists regarding tropical sea‐surface temperatures (SSTs) in open ocean settings during the PETM. Here, we present the first paired δ13C:Mg/Ca record derived in situ from relatively well‐preserved subdomains inside individual planktic foraminifer shells taken from a PETM record recovered in the central Pacific Ocean at Ocean Drilling Program Site 865. The δ13C signature of each individual shell was used to confirm calcification during the PETM, thereby reducing the unwanted effects of sediment mixing that secondarily smooth paleoclimate signals constructed with fossil planktic foraminifer shells. This method of “isotopic screening” reveals that shells calcified during the PETM have elevated Mg/Ca ratios reflecting exceptionally warm tropical SSTs (∼33–34°C). The increase in Mg/Ca ratios suggests ∼6°C of warming, which is more congruent with SST estimates derived from organic biomarkers in PETM records at other tropical sites. These extremely warm SSTs exceed the maximum temperature tolerances of modern planktic foraminifers. Important corollaries to the findings of this study are (a) the global signature of PETM warmth was uniformly distributed across different latitudes, (b) our Mg/Ca‐based SST record may not capture peak PETM warming at tropical Site 865 due to the thermally‐induced ecological exclusion of planktic foraminifers, and (c) the record of such transitory ecological exclusion has been obfuscated by post‐depositional sediment mixing at Site 865.
Seasonal Emergence and Circulation Coupling of Moist Layers Over the Tropical Atlantic
Authors: Prange Marc , Stevens Bjorn , Buehler Stefan A. 
Published: August 2024

AbstractMid‐tropospheric elevated moist layers (EMLs) near the melting level have been found in various regional observational studies in the tropics. Recently, a preponderance of EMLs in the presence of aggregated convection was found in cloud resolving simulations of radiative convective equilibrium (RCE), highlighting a significant circulation coupling. Here, we present global monthly EML occurrence rates based on reanalysis, yielding a broader view on where and when EMLs occur in the real world. Over the Atlantic, EML occurrence follows a seasonal cycle that maximizes in summer, aligning with maximized ITCZ intensity and organization. Resembling the results in RCE, the large‐scale circulation over the Atlantic shifts from a deep overturning in January to a bottom‐heavy circulation in July. While EMLs embedded in the July cross‐equatorial Hadley cell are found to be sourced from the ITCZ, EMLs north of the ITCZ emerge from the strongly sheared zonal flow over West Africa.
Reactive Nitrogen Partitioning Enhances the Contribution of Canadian Wildfire Plumes to US Ozone Air Quality
Authors: Lin Meiyun , Horowitz Larry W. , Hu Lu , Permar Wade 
Published: August 2024

AbstractQuantifying the variable impacts of wildfire smoke on ozone air quality is challenging. Here we use airborne measurements from the 2018 Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE‐CAN) to parameterize emissions of reactive nitrogen (NOy) from wildfires into peroxyacetyl nitrate (PAN; 37%), NO3− (27%), and NO (36%) in a global chemistry‐climate model with 13 km spatial resolution over the contiguous US. The NOy partitioning, compared with emitting all NOy as NO, reduces model ozone bias in near‐fire smoke plumes sampled by the aircraft and enhances ozone downwind by 5–10 ppbv when Canadian smoke plumes travel to Washington, Utah, Colorado, and Texas. Using multi‐platform observations, we identify the smoke‐influenced days with daily maximum 8‐hr average (MDA8) ozone of 70–88 ppbv in Kennewick, Salt Lake City, Denver and Dallas. On these days, wildfire smoke enhanced MDA8 ozone by 5–25 ppbv, through ozone produced remotely during plume transport and locally via interactions of smoke plume with urban emissions.
Horizontal Scales of Small‐ and Meso‐Scale Field‐Aligned Current Structures at Middle and Low Latitudes

Published: August 2024

AbstractBy utilizing the close orbital separation between Swarm A and C during the Counter Rotation Orbit phase, we check the agreement and stationarity between the FAC‐associated magnetic signatures at the two spacecraft through cross‐correlation analysis. When the agreement and stationarity are passed, the magnetic signature is considered suitable for small and meso‐scale Field‐aligned currents (FAC) estimates with dual‐spacecraft technique. It is found that at low and middle latitudes the dayside wave structure with apparent periods of about 10–60s can be observed around 90% of the time during all seasons. From those 90% can be identified as quasi‐static current structures. On the nightside, the shorter period signatures dominate the apparent period spectrum. At about 30% of the time structures with 1–7s periods are observed. For the longer period signals the proportion is reduced greatly. About 80% of these signatures with periods longer than 3s are identified as quasi‐static current structures. By taking advantage of the constantly changing longitudinal orbit separation during the considered time intervals, we can determine the mean separation at which the correlation breaks down. This provides FAC scale sizes in east‐west direction separately for FACs of various latitudinal wavelengths. The result shows that typical east‐west scale sizes of FAC structures with latitudinal wavelength of 10–400 km range from 10 to 60 km, respectively. FAC‐related structures on the nightside have been associated with medium‐scale traveling ionospheric disturbances and structures on the dayside primarily with FACs driven by atmospheric gravity waves.
