Simulation-Based Instruction in Continuing Education
Authors: Frank Eva M. , Doherty-Restrepo Jennifer , Roberts Lisa , Montalvo Alicia
Published: May 2020

Context

The results of this study will provide direction for integrating simulation into continuing professional education (CPE) for athletic trainers (ATs).

Objective

Compare the effects of 2 simulation techniques on knowledge and skill acquisition of a cardiovascular assessment.

Design

Randomized pretest-posttest design.

Setting

Continuing professional education course hosted at a simulation center.

Patients or Other Participants

Athletic trainers recruited to a CPE course. Twenty-two (age 22–49) of 30 ATs attended, consented, and completed the course. Participants were randomly assigned to a high-fidelity (12 participants) or low-fidelity (10 participants) group.

Intervention(s)

High-fidelity and low-fidelity simulation.

Main Outcome Measures(s)

A 31-question knowledge examination and a 4-station objective structured clinical examination (OSCE) measured knowledge and clinical skills, and specifically the ability to identify heart sounds as part of a comprehensive cardiovascular assessment.

Results

From pretest to posttest, all participants significantly improved knowledge (P < .001), clinical skills (P < .001), and heart-sound identification skill (P = .010). The high-fidelity group scored significantly higher (P = .48) than the low-fidelity group on the clinical skills portion of the OSCE.

Conclusions

Both simulation types can be used in CPE courses for ATs to reinforce the knowledge and skills that are a part of a cardiovascular assessment. High-fidelity simulation improved skill more than low-fidelity simulation because of the active nature of the intervention. Baseline scores were low, thereby strengthening the value to offer CPE to ATs specifically on the elements of conducting a comprehensive cardiovascular assessment. Adding a pretest can help identify knowledge and skill deficits before CPE participation.
Student Perceptions of Interprofessional Valuing After a Tabletop Interprofessional Education Simulation
Authors: Williams Mary L. , Camel Simone , Ocker Liette B. , Zinn Kelly , Grahovec Nicholas E. , Frazier Heather
Published: May 2020

Context

The focus of learning and working with professions outside of one's own is the essence of interprofessional education (IPE). Interprofessional education satisfies accreditation standards and is a high-impact teaching practice. Interprofessional education is often studied in nursing, medicine, and pharmacy; however, it has rarely been explored in athletic training.

Objective

To determine student perceptions of interprofessional valuing among a unique combination of disciplines.

Design

Survey.

Setting

Students were seated in interprofessional teams at round tables in a ballroom resembling a professional conference.

Patients or Other Participants

Forty prelicensure students participated in the tabletop simulation (athletic training = 12, dietetics = 9, nursing = 19). Of these participants, 36 completed the survey (athletic training = 9, dietetics = 8, nursing = 19).

Main Outcome Measure(s)

Student teams were given 2 cases and were prompted to discuss and complete accompanying tasks. Debriefing followed each case. Afterward, students were asked to complete the questionnaire. The Interprofessional Socialization and Valuing Scale-24 (ISVS) was used to assess interprofessional beliefs, attitudes, and behaviors.

Results

The ISVS and factor means were near the top of the survey scale, indicating that students had positive perceptions of interprofessional roles and socialization. All disciplines reported strong beliefs, attitudes, and behaviors towards IPE. No significant differences on the ISVS or subscales were identified among the disciplines or between those with and without previous IPE experience. Analysis of items revealed low scores for athletic training students on being able to share and exchange ideas in a team discussion, an important interprofessional behavior.

Conclusions

A combination of factors including newness to IPE, fewer IPE experiences, and unequal ratios of professions represented in each group may explain why athletic training students reported more challenges with sharing and exchanging ideas. Conducting a tabletop IPE events may facilitate the development of interprofessional valuing and socialization.
Athletic Trainers' Perceptions of Advanced Clinical Practice: Defining Advanced Clinical Practice in Athletic Training
Authors: Anderson Barton E. , Bacon Cailee E. Welch , Sauers Eric L.
Published: May 2020

Context

Advanced clinical practice is inherent in contemporary athletic training education, such as residency programs and Doctor of Athletic Training programs; however, as a concept, advanced clinical practice in athletic training has been poorly studied to date.

Objective

To explore athletic trainers' perceptions of advanced clinical practice.

Design

Cross-sectional.

Setting

Online survey with open-ended questions.

Patients or Other Participants

Three hundred fifty of 1992 athletic trainers accessed the survey (17.6% access rate); 321 respondents completed at least 1 open-ended question; and 196 completed the survey in its entirety (61.1% completion rate).

Intervention(s)

We used a 13-item survey including demographic items (9 items) and open-ended response questions (4 items).

Main Outcome Measure(s)

Guided by the consensual qualitative research approach, a 3-person data analysis team coded the open-ended responses. Each member coded 50 responses and a consensus codebook was developed. Two members of the team coded the remaining responses, which were confirmed by the third member. Emergent data were organized into themes and categories, and frequency counts were determined for each category.

Results

Athletic trainers' definitions of advanced clinical practice were categorized into 4 emergent categories: (1) formal training and education; (2) informal training and education; (3) knowledge, skills, and behaviors; and (4) experience and uncertainty.

Conclusions

The categories of formal and informal training and education focused on athletic trainers acquiring additional knowledge and skills through mechanisms such as postprofessional degree programs, residency programs, or other areas of study. The knowledge, skills, and behaviors category included areas related to specialized skills and the core competencies. These 3 categories aligned with one another to provide both the types of knowledge, skills, and behaviors that define advanced clinical practice, and the specific mechanisms through which an athletic trainer can achieve advanced clinical practice.
Stakeholder Perceptions of Clinical Immersion in Athletic Training Programs
Authors: Harris Ashley M. , Volberding Jennifer L. , Walker Stacy E.
Published: May 2020

Context

Multiple concepts contribute to effective clinical education practice, such as professional socialization, mentoring, and intergenerational learning differences. As the professional degree transition occurs, programs are being afforded the opportunity to restructure clinical education experiences. In March of 2018, the Commission on Accreditation of Athletic Training Education released the newest version of the professional program accreditation standards, and 1 of the new standards that has been adopted requires programs to include a 4-week immersive experience. This concept of immersion as a means to deliver clinical education is not a new concept, but few use it in athletic training.

Objective

Identify perceptions of immersion as seen by athletic training educators and offer potential integration methods.

Design

Qualitative interviews conducted over the fall and winter of 2017.

Setting

Individual phone interviews.

Patients or Other Participants

Eleven athletic training educators with a variety of demographic characteristics.

Main Outcome Measure(s)

We analyzed data using the constant comparative method (2 researchers). A third then analyzed data for triangulation.

Results

Three themes were identified: (1) benefits of immersion, (2) implementation concerns, and (3) strategies for implementation.

Conclusions

Although many debate the length of immersive experiences and the value that such an experience brings, educators within this study agreed that immersion would provide benefits to their current clinical offerings. Additionally, individuals currently offering immersion experiences provided real-life examples and strategies that have the potential to provide insight and guidance for those who are still looking at options for implementation.
An investigation on the GNSS ionospheric mapping-functions uncertainties using NeQuick model
Authors: Ghoddousi-Fard R
Published: May 2020

Commonly used two-dimensional ionospheric models for GNSS positioning applications, including Total Electron Content (TEC) maps, require a mapping function (obliquity factor) which is used for conversion between vertical and slant TEC at ionospheric pierce
points. In this paper, NeQuick, a three-dimensional semi-empirical model, is used to simulate the level of uncertainties that one may expect from more simplified approaches. In order to evaluate the performance of mapping functions on GNSS vertical TEC estimation, coinciding pierce points from mixed
stations and receivers from stations over North America are analyzed. A fit to the NeQuick derived mapping function values resulted in an empirical mapping function which performed slightly better than commonly used mapping functions during the studied periods and locations.

Avaliação de Materiais Didáticos de Português como Língua Adicional em Face a Necessidades Específicas de Aprendizes Universitários
Authors: Pereira Gilberto , Romero Tania Regina De Souza
Published: May 2020

É crescente a demanda por materiais de Português como Língua Adicional (PLA) no contexto acadêmico devido à internacionalização das universidades (Figueiredo, Osório e Miranda, 2016). Visando ao preparo do professor (Almeida Filho, 2011), é relevante analisar, todavia, se os materiais disponíveis cumprem com as necessidades comunicativas dos aprendizes (Hall, 2005; Tomlinson, 2012). Assim, o propósito desse artigo é avaliar materiais didáticos de PLA mais usados no Brasil, tendo-se em vista necessidades específicas (Hutchinson e Waters, 1987) de um grupo de cinco estudantes estrangeiros em uma Universidade pública. Para tanto, esta pesquisa tem características quali-quantitativa porque se apoia na visão de apenas cinco estudantes, mas também quantifica ocorrências de situações comunicativas para que se possa comparar os seis materiais didáticos selecionados (Bortoni-Ricardo, 2008). Os resultados mostram que os materiais cumpriam com 30% das necessidades dos aprendizes, dado que reafirma a importância do levantamento de necessidades no ensino de PLA.
As Metamorfoses no discurso e o surgimento do novo homo politicus na corrida eleitoral em 2018
Authors: De Oliviera Rafael Camargo , De Sousa Kátia Menezes
Published: May 2020

Este trabalho tem como objetivo analisar as formas de construção do sujeito político na atualidade ou, como optamos por utilizar no decorrer do texto, o novo homo politicus. O conceito foi utilizado por Jean-Jacques Courtine em seu artigo ‘As metamorfoses do homo politicus’, publicado no Brasil em Legados de Pêcheux: inéditos em análise do discurso (PIOVEZANI; SARGENTINI, 2011). Para efetivar os estudos, utilizamos as noções de enunciado, discurso, saber e poder consolidadas pelo filósofo francês M. Foucault. Sendo assim, esta pesquisa se insere nos estudos foucaultianos do discurso e utiliza-se da arqueologia e da genealogia para a construção do método de análise. Como aporte teórico, as obras utilizadas foram: Arqueologia do saber (2012), Vigiar e Punir (2011), História da sexualidade I (1988) e O nascimento da biopolítica (2008).
ETİK OLMAYAN TÜKETİCİ DAVRANIŞLARININ NEDENLERİ
Authors: ÜNAL KESTANE Serpil
Published: May 2020

Günümüzde ekonomik kalkınma kaygılarının yanında yeryüzünün geleceğine yönelik kaygıların da artması ile sürdürülebilir kalkınma kavramı ortaya çıkmıştır. Bu kavram ilk yıllarında üretim bazında ele alınıp incelenmiş ancak sonraki yıllarda sürdürülebilir tüketimin sürdürülebilir kalkınmada temel bileşenlerden biri olduğu düşünülmeye başlanmıştır. Böylece sürdürülebilir kalkınma kavramı tüketim yönünden de ele alıp incelenmeye başlanmıştır. Çünkü tüketiciler sosyal olarak sorumlu davranışları ile sürdürülebilirlik konusunda çok önemli bir aktördür.
Bu araştırmada da tüketicilerin tüketim konusunda daha olumlu davranışlar geliştirmelerini ve bu konudaki toplumsal hareketlere tam anlamıyla aktif katılımlarını engelleyen engellerin neler olduğu belirlenmeye çalışılmaktadır. Bunun için araştırmada hem nicel hem de nitel yöntemlerinden yararlanılmıştır. Nicel çalışmada, daha önce d’Astous ve Legendre tarafından geliştirilerek Kanadalı yetişkin tüketiciler üzerinde uygulanan ve doğrulanan CRUB ( Consumer Reason for Unethical Behavior) ölçeği DEÜ İMYO’da toplam 234 öğrenciye uygulanmıştır. Nitel araştırma yöntemlerinden derinlemesine görüşmeler aracılığıyla da araştırma desteklenmiştir.
Elde edilen ölçek verileri SPSS paket programında istatistiksel analizlere tabi tutularak değerlendirilmiştir. Kanada’daki çalışmada ölçek 3 faktöre ayrılırken Türk Öğrenciler üzerinde yapılan bu pilot çalışmada ölçek 6 ayrı faktör altında toplanmıştır. Ölçekte öğrencilerin tüketim konusunda etik tutum ve davranışlara sahip oldukları, etik olmayan davranışlarının temelinde ise daha çok ekonomik sebeplerin yer aldığı görülmüştür. Ayrıca öğrencilere göre etik tüketim davranışlarının sağlanmasında en büyük sorumluluk devlete aittir.
CFO’s Working as The Board Secretary Concurrently and Corporate Disclosure Quality: Based on Empirical Evidence of Listed Companies in Shenzhen Stock Exchange
Authors: Rui Xiang , Xing Qian
Published: May 2020

This paper took the selected data listed companies in Shenzhen Stock Exchange in 2008-2015 as samples to study the relationship between the CFO’s working as the Board Secretary concurrently and corporate disclosure quality, and also to examine the impact of different government intervention levels and nature of property rights. The results indicate that the CFO’s doubling as the Board Secretary can distinctly improve the quality of corporate disclosure in listed companies; the CFO’s holding concurrently the post of the Board Secretary can improve noticeably the disclosure quality of listed companies in regions with a high degree of government intervention; the CFO’s also serving as the Board Secretary can improve the disclosure quality of non-state-owned listed companies. Moreover, this paper presents a reasonable explanation for the phenomenon that increasingly more CFOs are serving as the Board Secretaries simultaneously via empirical study. Lastly, conclusions of this study can provide empirical evidence for the appointment of the Board Secretary in listed companies.

A Class of Block Multi-derivative Numerical Techniques for Singular Advection Equations
Authors: Ogunniran M. O.
Published: May 2020

The integration of some differential equations is hard to acquire because of the presence of singular point(s) in these equations. These equations are best solved by some unique technique. Multi-derivative techniques have a long history of powerful integration of such equations yet till date, a couple of class of this technique has been explored for integrating partial differential equations. This work centers around the development, analysis, and implementation of a class of multi-derivative technique on partial differential equations. The approaches were effectively analyzed and were turned out to be consistent, stable and convergent. Numerical outcomes got likewise demonstrated the approximation quality of the technique over existing techniques in the literature.
Investigating the Performance of Point to Multipoint Microwave Connectivity across Undulating Landscape during Rainfall
Authors: Ukhurebor Kingsley , Nwankwo Wilson
Published: May 2020

One of the most debated issues surrounding wireless connectivity is performance especially under different topographic and climatic scenarios. Performance has a direct relationship with throughput measured in terms of how well a given wireless connectivity provides consistent services over a given period compared to the wired alternative. Research has shown that wireless connectivity is constrained by significant physical components such as topography, weather conditions, propagation frequency, and distance. It is commonplace to see notable vendors of wireless network products make claims as to how their technologies are designed to remedy any signal degradation that may arise from the aforementioned physical elements. This paper is aimed at evaluating the performance of a point to multipoint connectivity using Ubiquiti’s 5.8 GHz Point to Multipoint Base Stations deployed within a landscape marked by series of undulating highlands and lowlands. In this experiment, a base station node is established with connectivity to two other nodes of same specifications with one node as the destination radio whereas the other acts as the control which is located on a table land. The nodes were separated by triangular distances of 3 km and network connectivity was maintained over thirty days during periods of rainfall. Packets sent and received across each node was carefully recorded. The results from the analysis showed that packet losses to and from the control node was significantly lower than that of the other node under same weather conditions.
Optimization of Method and Components of Enzymatic Fuel Cells
Authors: Akinsola Ibukun , Alabi Aderemi Babatunde , Soliu Muibat     A , Akomolafe Taiye
Published: May 2020

Enzymatic fuel cells produce electrical power by oxidation of renewable energy sources. An enzymatic glucose biofuel cell uses glucose as fuel and enzymes as biocatalyst, to convert biochemical energy into electrical energy. The applications which need low electrical voltages and low currents have much of the interest in developing enzymatic fuel cells. The cell was constructed using three different materials with different electrodes (Bitter leaf and Copper electrodes (BCu), Bitter leaf and Carbon electrodes (BC) and Water leaf and Carbon electrodes (WC)). The short circuit current and open circuit voltage were measured in micro-ampere (mu A) and milli-volt (mV) respectively at 30 minutes interval over the period of 12 hours (from dawn to dusk). The results which show that fuel cells constructed using bitter leaf with carbon electrode has the highest open circuit voltage, short circuit current and generated power of 162.8~mV, 1.65~ mu A and 268.62~nW respectively at 720~mins is obtained from the plots generated by the use of Microsoft Excel. The results show that all short circuit currents, voltages and powers generated increases with time and this is as a result of the exposure to solar radiation during the period of taking the measurement.

This study focuses on the anatase TiO2 doped Fluorine to investigate their structural and electronics properties using Density Functional Theory (DFT) within generalized gradient approximation (GGA) as implemented in Quantum ESPRESSO (QE). For the anatase TiO2 phase the calculated electronic band structures of pure TiO2 and TiO2 doped Fluorine nanocrystals are displayed along a high symmetry directions and the energy range of band structure is plotted from 0.0 eV to 3.9 eV , the energy separation between the bottom of the conduction band and the top of valence band occurred at the Γ and  points, indicating that  anatase TiO2 is an indirect band gap material with an approximate value of 2.30 eV energy gap, this value is consistent with previous DFT result. When F is added the band structure did not change much because ﬂuorine element doping is conducive to the generation of Oxygen holes and enhances the mobility of effective electrons which can enhance the conductivity of the adsorbent substrate and improve the solar cell performance of the ﬂuorine-doped TiO2. The band gap value obtained for F doped TiO2 was found to be 2.11 eV. The dopant formation energy of Fluorine is calculated to be -55.6 Ry which is equivalent to -756.5 eV.

In this paper, we proposed a new Randomized Response Model (RRM) that estimate proportion of people in a population (P) belonging to a sensitive group (S) under study. Simple random sampling with replacement and stratiﬁed simple random sampling scheme were adopted. Maximum likelihood and Bayesian estimation procedures of the proposed model were developed and compared. The sampling distribution (expectation and variance) of the proposed estimator under the two sampling techniques, eﬃciency comparison of the proposed model with some existing models, and numerical illustration of all the compared models were also explored. We found that the proposed model outperformed other existing RRMs in terms of eﬃciency and it proved to be more protective in designing survey for sensitive related issues.

Obtaining of ZnTa2O6 and ZnV2O6 pseudo-binary oxide materials by hydrothermal and coprecipitation methods and of Zn(II) 5-pyridyl-10,15,20-tris-(3,4-di-methoxy-phenyl) porphyrin (ZnPydiMeOPP) are presented. Mixed thin films of pseudo-binary oxide materials and Zn-porphyrin were realized by pulsed laser deposition (PLD) technique on steel disks and corrosion tests in 0.1 M HCl solution were performed. The inhibition efficiency (IE) in all cases containing porphyrin was always higher than 80%. The best IE (84.50%) was obtained for the sandwich structure using the hydrothermally obtained ZnV2O6 oxide as the first layer and the ZnPydiMeOPP porphyrin as the second layer. The mechanism of corrosion protection can be explained by the physical/mechanical barrier effect.

Authors: Coutinho Fábio , Teixeira Francimar
Published: May 2020

Este estudo buscou compreender concepções de ensino-aprendizagem de materiais didáticos dos subprojetos de Biologia do Programa Institucional de Bolsa de Iniciação à Docência, da Universidade Federal de Pernambuco. Para tanto, empreendemos uma pesquisa documental, a partir da seleção e análise de propostas metodológicas de materiais didáticos, planejadas para a realização de práticas de ensino. Constatamos que os materiais estavam embasados em modelos procedimentais prefixados, que propuseram conduzir a experiência mediante a confirmação ou reprodução de verdades científicas. Além disso, os materiais didáticos apresentaram orientações para a revisão de conhecimentos, com vistas a conduzir os alunos ao resgate de questões de aulas precedentes. Esses elementos revelaram a concepção tradicional de ensino-aprendizagem, corroborando a visão do conteúdo e da lógica disciplinar que está refletida na estrutura curricular dos cursos de licenciatura em biologia, onde a compreensão da ciência funda-se na ideia de objetividade, de forma apartada do próprio sujeito que a constitui.
A sobrevivência da estátua
Authors: Zacchi André Piazera
Published: May 2020

No poema de Manuel Bandeira o cacto é uma estátua. Essa estátua tomba e interrompe a vida na cidade. Na morte o cacto se historiciza e, nesse sentido, ganha vida. A montagem das imagens no poema e sua leitura vertical, livre, nos apontam para outras imagens como as da escultura negra de Carl Einstein e sua leitura por Chris Marker e Alain Resnais em As estátuas também morrem, ou imagens como as poses dos nativos em ¡Que viva México! de Eisenstein. A morte revolucionária e a intratabilidade fazem do cacto uma estátua sobrevivente.

Abstract. We propose a new technique of remote wind measurements based on Doppler analysis of a CO2 absorption line in the 1.605 µm overtone band measured in the direct Sun observation geometry. Heterodyne
spectroradiometric measurements of the solar radiation passing through the
atmosphere provide an unprecedented spectral resolution up to λ/δλ∼6×107, with a signal-to-noise ratio of more than 100. The shape of the individual rotational line profile provides an unambiguous relationship between the offset from the line center and the altitude at which the respective part of the line profile is formed. Therefore, an inverse problem may be posed in order to retrieve the vertical distribution of wind because with retrievals the vertical resolution is compromised by a spectral resolution and the signal-to-noise ratio of the measurements. A close coincidence between the measured and synthetic absorption line is reached, with retrieved wind profiles between the surface and 50 km being in good agreement with reanalysis models. This method may pose an alternative to widely employed lidar and radar techniques.
Atmospheric observations of the water vapour continuum in the near-infrared windows between 2500 and 6600 cm−1

Abstract. Water vapour continuum absorption is potentially
important for both closure of the Earth's energy budget and remote sensing
applications. Currently, there are significant uncertainties in its
characteristics in the near-infrared atmospheric windows at
2.1 and 1.6 µm. There have been several attempts to measure the continuum in the
laboratory; not only are there significant differences amongst these
measurements, but there are also difficulties in extrapolating the laboratory
data taken at room temperature and above to temperatures more widely
relevant to the atmosphere. Validation is therefore required using field
observations of the real atmosphere. There are currently no published
observations in atmospheric conditions with enough water vapour to detect a
continuum signal within these windows or where the self-continuum component
is significant. We present observations of the near-infrared water vapour
continuum from Camborne, UK, at sea level using a Sun-pointing,
radiometrically calibrated Fourier transform spectrometer in the window
regions between 2000 and 10 000 cm−1. Analysis of these data is challenging,
particularly because of the need to remove aerosol extinction and the large
uncertainties associated with such field measurements. Nevertheless, we
present data that are consistent with recent laboratory datasets in the 4 and
2.1 µm windows (when extrapolated to atmospheric temperatures). These
results indicate that the most recent revision (3.2) of the
MT_CKD foreign continuum, versions of which are widely used
in atmospheric radiation models, requires strengthening by a factor of
∼5 in the centre of the 2.1 µm window. In the
higher-wavenumber window at 1.6 µm, our estimated self- and foreign-continua are significantly stronger than MT_CKD. The possible
contribution of the self- and foreign-continua to our derived total continuum
optical depth is estimated by using laboratory or MT_CKD
values of one, to estimate the other. The obtained self-continuum shows some
consistency with temperature-extrapolated laboratory data in the centres of
the 4 and 2.1 µm windows. The 1.6 µm region is more sensitive to
atmospheric aerosol and continuum retrievals and therefore more uncertain
than the more robust results at 2.1 and 4 µm. We highlight the
difficulties in observing the atmospheric continuum and make the case for
additional measurements in both the laboratory and field and discuss the
requirements for any future field campaign.
Improvement of numerical weather prediction model analysis during fog conditions through the assimilation of ground-based microwave radiometer observations: a 1D-Var study

Abstract. This paper investigates the potential benefit of ground-based microwave radiometers (MWRs) to improve the ini- tial state (analysis) of current numerical weather prediction (NWP) systems during fog conditions. To that end, temperature,humidity and liquid water path (LWP) retrievals have been performed using a one-dimensional variational technique (1D-Var) during a fog dedicated field-experiment performed over winter 2016–2017 in France. In-situ measurements from a 120 m tower and radiosoundings are used to assess the improvement brought by the 1D-Var analysis to the background. A sensitivity study demonstrates the importance of the cross-correlations between temperature and specific humidity in the background-error-covariance matrix as well as the bias-correction applied on MWR raw measurements. With the optimal 1D-Var configuration, a root-mean-square error smaller than 1.5 K (resp. 0.8 K) for temperature and 1 g kg−1 (resp. 0.5 g kg−1) for humidity is obtained up to 6 km altitude (resp. within the fog layer up to 250 m). A thin-radiative fog case study has shown that the assimilation of MWR observations was able to correct large temperature errors of the AROME model as well as vertical and temporal errors observed in the fog lifecycle. During missed fog profiles, 1D-Var increments pull towards lower temperature close to the ground and higher temperature above 100 m altitude, i.e. higher atmospheric stability. The largest analysis increments and background errors are observed during false alarms when the AROME forecasts tend to significantly overestimate the temperature cooling. The impact on specific humidity was found neutral to slightly positive. The impact on LWP was found significant with 1D-Var increments within 200 g m−2 and RMSE with respect to MWR statistical regressions decreased from 101 g m−2 in the background to 27 g m−2 in the 1D-Var analysis. These encouraging results led to the deployment of 8 MWRs during the international SOFOG3D (SOuth FOGs 3D experiment for fog processes study) experiment conducted by Météo-France.
