description: English Summary
Research software is commonly used in various disciplines to perform research and as a research object itself. Therefore, it is covered by multiple NFDI consortia. To fulfill the FAIR criteria for research software, it needs to be described with meaningful and interoperable metadata enhancing transparency, reproducibility, and reusability in research. While there exist some metadata schemes for research software, e.g., CodeMeta, they have some limitations, e.g., missing elements and missing semantic interoperability.
To address these issues, this working group aims to provide a comprehensive metadata vocabulary for research software, compatible with existing frameworks such as schema.org and CodeMeta. Also, the working group will support all NFDI consortia in applying the vocabulary as well as develop domain-specific extensions if needed.
German Summary
Forschungssoftware wird in vielen Bereichen der Wissenschaft zur Forschung genutzt und stellt teilweise selbst ein Forschungsobjekt dar. Viele NFDI-Konsortien decken Forschungssoftware als wichtiges Forschungsartefakt mit ab und wollen, dass Forschungssoftware in Zukunft die FAIR-Kriterien erfüllt, um die Transparenz, Reproduzierbarkeit und Wiederverwendbarkeit in software-basierter Forschung zu erhöhen. Damit Forschungssoftware die FAIR-Kriterien erfüllt, muss sie mit aussagekräftigen und interoperablen Metadaten beschrieben werden. Dafür werden entsprechende Metadatenschemata benötigt. Es gibt zwar einige Metadatenschemata für Forschungssoftware, z. B. CodeMeta, aber sie weisen einige Einschränkungen auf, z. B. fehlende Elemente und fehlende semantische Interoperabilität. Um diese Probleme zu beheben, hat sich diese Arbeitsgruppe zum Ziel gesetzt, ein umfassendes Metadatenvokabular für Forschungssoftware bereitzustellen, das mit bestehenden Standards wie schema.org und CodeMeta kompatibel ist. Damit wird die Arbeitsgruppe alle NFDI-Konsortien bei der Anwendung und Etablierung von Metadatenschemeta für Forschungssoftware unterstützen, z.B. bei Entwicklung von bereichsspezifischen Erweiterungen.

description: We present dissolved and total dissolvable trace elements for spring and summer cruises in 2010 in the high‐latitude North Atlantic. Surface and full depth data are provided for Al, Cd, Co, Cu, Mn, Ni, Pb, and Zn in the Iceland and Irminger Basins, and consequences of biological uptake and inputs by the spring Eyjafjallajökull volcanic eruption are assessed. Ash from Eyjafjallajökull resulted in pronounced increases in Al, Mn, and Zn in surface waters in close proximity to Iceland during the eruption, while 3 months later during the summer cruise levels had returned to more typical values for the region. The apparent seasonal removal ratios of surface trace elements were consistent with biological export. Assessment of supply of trace elements to the surface mixed layer for the region, excluding volcanic inputs, indicated that deep winter mixing was the dominant source, with diffusive mixing being a minor source (between 13.5% [dissolved Cd, DCd] and −2.43% [DZn] of deep winter flux), and atmospheric inputs being an important source only for DAl and DZn (DAl up to 42% and DZn up to 4.2% of deep winter + diffusive fluxes) and typically less than 1% for the other elements. Elemental supply ratios to the surface mixed layer through convection were comparable to apparent removal ratios we calculated between spring and summer. Given that deep mixing dominated nutrient and trace element supply to surface waters, predicted increases in water column stratification in this region may reduce supply, with potential consequences for primary production and the biological carbon pump.
description: Key Points: Bio‐essential element concentrations in surface waters decreased from spring to summer with removal ratios reflecting biological uptake. Effects of volcanic inputs from Eyjafjallajökull in spring 2010 were pronounced for Al, Mn, and Zn but returned to typical levels in summer. Deep winter convection dominated trace element supply to surface waters with minor contributions from atmospheric and diffusive mixing.

description: The nuclear structure of even-even and odd lead isotopes (178-236 Pb) is investigated within the Hartree-Fock-Bogoliubov theory. Calculations are performed for a wide range of neutron numbers, starting from the proton-rich side up to the neutron-rich side, by using the SLy4 Skyrme interaction and a new proposed formula for the pairing strength which is more precise for this region of nuclei as we did in previous works in the regions of Neodymium (Nd, Z=60) [Int. J. Mod. Phys. E 24, 1550073 (2015)] and Molybdenum (Mo, Z=42) [Nuc. Phys. A 957 22-32 (2017)]. Such a new pairing strength formula allows reaching exotic nuclei region where the experimental data are not available. Calculated values of various physical quantities such as binding energy, two-neutron separation energy, and rms-radii for protons and neutrons are discussed and compared with experimental data and some estimates of other nuclear models like Finite Range Droplet Model (FRDM), Relativistic Mean Field (RMF), Density-Dependent Meson-Exchange Relativistic Energy Functional (DD-ME2) and results of Hartree-Fock-Bogoliubov calculations based on the D1S Gogny effective nucleon-nucleon interaction (Gogny D1S).

description: Zusammenfassung Als langjähriges und aktives Mitglied der Gesellschaft Naturforschender Freunde zu Berlin bestimmte Ehrenberg ihre Aktivitäten und ihr Ansehen maßgeblich mit. Seine Beiträge zu den Sitzungen und Schriften und seine Rolle als Bewohner des gesellschaftseigenen Hauses förderten in der GNF sowohl Fortschritt als auch Beständigkeit. Das Ziel der Naturgeschichte des 18. Jahrhunderts, also die Entdeckung, Beschreibung und Bewahrung möglichst aller Organismen- und Gesteinsarten, wurde in der GNF bis in die zweite Hälfte des 19. Jahrhunderts tradiert. Ehrenbergs wissenschaftliche Leistungen, insbesondere seine zahlreichen Entdeckungen mit Hilfe des Mikroskops, stehen ganz in dieser Tradition. Abstract As a long-time and active member of the Gesellschaft naturforschender Freunde zu Berlin (Berlin Society of Friends of Natural Research), Ehrenberg played a major role in determining the society’s activities and shaping its reputation. His contributions to the meetings, his writings, and his role as a resident of the house belonging to the society promoted both progress and permanence of the association. The goal of natural history in the 18th century, that is, the discovery, description, and preservation of as many species of organisms and rocks as possible, was carried forth by the Gesellschaft naturforschender Freunde into the second half of the 19th century. Ehrenberg’s scientific achievements, particularly his numerous discoveries with the aid of the microscope, belong entirely to this tradition. Résumé En tant que membre actif et de longue date de la Gesellschaft naturforschender Freunde zu Berlin (Société des amis naturalistes de Berlin), Ehrenberg a joué un rôle majeur en déterminant les activités et la réputation de cette société. Ses contributions aux réunions et aux écrits et son statut d’habitant de la maison appartenant à la société ont favorisé à la fois le progrès et la pérennité de l’association. L’objectif de l’histoire naturelle au XVIIIe siècle, c’est-à-dire la découverte, la description et la préservation d’autant d’espèces d’organismes et de roches que possible, a été perpétué par la Gesellschaft naturforschender Freunde jusqu’à la seconde moitié du XIXe siècle. Les travaux scientifiques d’Ehrenberg, notamment ses nombreuses découvertes à l’aide du microscope, s’inscrivent entièrement dans cette tradition.

description: Heinrich Menu von Minutoli unternahm 1820 eine Reise nach Nordafrika zur Erforschung ägyptischer und griechischer Altertümer. Die Preußische Akademie der Wissenschaften bestimmte die jungen Naturforscher Christian Gottfried Ehrenberg und Wilhelm Hemprich als weitere Teilnehmer. Während Minutoli bereits ein Jahr nach Beginn der Expedition 1821 nach Europa zurückkehrte, setzten Ehrenberg und Hemprich ihre Forschungen fort. Von Alexandria aus unternahmen sie, zum Teil getrennt, Exkursionen in die libysche Wüste, auf die Sinaihalbinsel, zum Roten Meer, in das Libanongebirge sowie bis in den Sudan und nach Eritrea, wo Hemprich 1825 dem Malariafieber erlag. Wie von der Akademie der Wissenschaften beauftragt, sammelten Ehrenberg und Hemprich insgesamt 34 000 Tiere, 46 000 Pflanzen und 300 Mineralien. Diese trafen im Laufe der Jahre, verpackt in insgesamt 114 Kisten, in Berlin ein. Die Akademie stellte Mittel für die Auswertung der Sammlungen zur Verfügung. Ehrenbergs Reisebericht blieb aber ebenso Fragment wie das großangelegte Tafelwerk Symbolae physicae.

description: „Eine der größten Freuden meines Lebens würde sein, einmal 5 – 6 Monathe mit Ihnen, an Ihrer Seite, unter Ihrer Belehrung reisen zu können. Süßwassermuscheln, Fische, Bergpflanzen Rußlands sind wenig bekannt.“ Mit diesen Worten lud Alexander von Humboldt seinen Akademiekollegen Ehrenberg zur Teilnahme an der russisch-sibirischen Reise ein, die der preußische Kammerherr auf Einladung des Kaisers Nikolaj I. unternahm. Knapp drei Jahre nach der Rückkehr von der arabisch-afrikanischen Forschungsreise brach Ehrenberg also erneut auf: Am 12. April 1829 traten Humboldt, Ehrenberg und der Mineraloge Gustav Rose ihre Reise in Berlin an. Diese führte sie in knapp neun Monaten und über 19 000 Kilometer in den Ural und durch Westsibirien bis zur russisch-chinesischen Grenzstation Baty. Während Humboldt und Rose die Hüttenbezirke im Ural und Altai inspizierten, legte Ehrenberg botanische und zoologische Sammlungen an.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: The Atlantic Meridional Overturning Circulation (AMOC) plays a major role in the global and local climates by redistributing heat through the global ocean. Current climate projections indicate a consistent weakening of the AMOC strength which could be sign of a forthcoming collapse. There is strong evidence that such events occurred in the geological past. This work aims at evaluating the risk of AMOC transitioning to a collapsed state by 2100 using a global ocean model. To estimate the transition probability using such a complex model, the trajectory-adaptive multilevel splitting (TAMS) method is employed to greatly reduce the computational cost associated with classical Monte-Carlo approach when tackling rare events. We developed an implementation of the TAMS method amendable to expensive simulations, relying on the Omuse framework to interface the TAMS algorithm with the POP high fidelity ocean model. Early results indicate the viability of the proposed approach and ongoing effort aim at further improving the method by selecting a better score function, a key component of the TAMS method.

description: The future of exoplanet detection lies in the mid-infrared (MIR). The MIR region contains the blackbody peak of both hot and habitable zone exoplanets, making the contrast between starlight and planet light less extreme. It is also the region where prominent chemical signatures indicative of life exist, such as ozone at 9.7 microns. At a wavelength of 4 microns the difference in emission between an Earth-like planet and a star like our own is 80 dB. However a jovian planet, at the same separation exhibits 60 dB of contrast, or only 20 dB if it is hot due to its formation energy or being close to its host star. A two dimensional nulling interferometer, made with chalcogenide glass, has been measured to produce a null of 20 dB, limited by scattered light. Measures to increase the null depth to the theoretical limit of 60 dB are discussed.

description: We show that the interplay between excluded volume effects, hydrophobicity, and hydrogen bonding of a tube-like representation of a polypeptide chain gives rise to free energy landscapes that exhibit a small number of metastable minima corresponding to common structural motifs observed in proteins. The complexity of the landscape increases only moderately with the length of the chain. Analysis of the temperature dependence of these landscapes reveals that the stability of specific metastable states is maximal at a temperature close to the mid-point of folding. These mestastable states are therefore likely to be of particular significance in determining the generic tendency of proteins to aggregate into potentially pathogenic agents.

description: We present the results of our spatially resolved investigation into the interplay between the ages of the stellar populations and the kinematics of the warm ionised outflows in the well-studied type II quasar Markarian 34. Utilising IFS data, we determine the spatial distribution of the young stellar population (YSP; $t_{ysp} < 100 \mbox{ Myr}$) using spectral synthesis modelling. We also employ the $\mbox{[OIII]}λ5007$ emission line as a tracer of the warm ionised gas kinematics. We demonstrate a spatial correlation between the outer edges of the blue-side of the outflow and an enhancement in the proportion of the YSP flux, suggesting that the outflow is responsible for triggering star formation in this region. In regions with more highly disrupted gas kinematics, we find that the proportion of YSP flux is consistent with that found outside the outflow region, suggesting that the increased disruption is preventing a similar enhancement in star formation from occurring. Our analysis suggests that Mrk 34 is an example of quasar driven outflows simultaneously producing both `positive' and `preventive' feedback, further demonstrating the complex nature of the relationship between quasars and their host galaxies.

description: We study the formation of the calcium II infrared triplet lines 8498Å, 8542Åand 8662Å, in the accreting magnetospheric flows of Classical T Tauri stars (CTTS), and present a grid of models for a large range of magnetospheric conditions. We apply our models to the interpretation of multi epoch observations of the CTTS DI Cep. We find that these lines form in the magnetospheric infall and that the variability of the CaII triplet lines in DI Cep can be explained in the context of changes in the mass accretion rate/temperature of the accretion column gas.

Enrichment of Jupiter's atmosphere by late planetesimal bombardment

description: Jupiter's atmosphere is enriched with heavy elements by a factor of about 3 compared to proto-solar. The origin of this enrichment and whether it represent the bulk composition of the planetary envelope remain unknown. Internal structure models of Jupiter suggest that its envelope is separated from the deep interior and that the planet is not fully mixed. This implies that Jupiter's atmosphere was enriched with heavy elements just before the end of its formation. Such enrichment can be a result of late planetesimal accretion. However, in-situ Jupiter formation models suggest the decreasing accretion rate with increasing planetary mass, which cannot explain Jupiter's atmospheric enrichment. In this study, we model Jupiter's formation and show that an migration of proto-Jupiter from $\sim$ 20 AU to its current location can lead to a late planetesimal accretion and atmospheric enrichment. Late planetesimal accretion does not occur if proto-Jupiter migrates only a few AU. We suggest that if Jupiter's outermost layer is fully-mixed and is relatively thin (up to $\sim$ 20\% of its mass), such late accretion can explain its measured atmospheric composition. It is therefore possible that Jupiter underwent significant orbital migration followed by late planetesimal accretion.

Mechanism of Ambipolar Field-Effect Transistors on One-Dimensional Organic Mott Insulators

description: The experimentally observed, ambipolar field-effect characteristics of Mott insulators are reproduced in the one-dimensional Hubbard model attached to a tight-binding model for source and drain electrodes. The formation of Schottky barriers, originating from the work-function difference, is taken into account by a potential satisfying the Poisson equation with an appropriate boundary condition. Then, these field-effect characteristics are shown to be related by unique current-voltage characteristics of metal-Mott-insulator interfaces.

description: Zusammenfassung Ulrich Päßler konnte im September 2019 den verschollen geglaubten Brief von Carl Friedrich Gauß an Alexander von Humboldt vom 17. August 1832 wiederfinden. Dieser Brief stammt aus der Anfangsphase von Gauß’ erdmagnetischen Forschungen. Gauß gibt an, sich erst vor einem halben Jahr in dieses Gebiet gewagt zu haben, das bislang Humboldt vorbehalten war. Die wichtigsten Themen des Briefes sind der Einfluss der Temperatur auf die magnetischen Eigenschaften sowie die Methoden der Magnetisierung von Nadeln und Stäben. Der Brief füllt eine wichtige Lücke in der Korrespondenz zwischen Gauß und Humboldt und ergänzt unsere Kenntnisse über bisher kaum wahrgenommene Forschungsfelder von Gauß. Es wird eine kritische kommentierte Edition des Briefes vorgestellt. Résumé Au mois de septembre 2019, Ulrich Päßler a pu retrouver la lettre de Carl Friedrich Gauss à Alexander von Humboldt du 17 août 1832 qui était disparue. A ce temps-là, Gauss avait commencé à s’occuper de la recherche du magnétisme terrestre. Il mentionne qu’il a osé faire des recherches sur un domaine que Humboldt avait étudié jusque-là. Les sujets les plus importants de la lettre sont l’influence de la température sur les propriétés magnétiques et les méthodes de l’aimantation d’aiguilles et de barres. Cette lettre remplit une des lacunes dans la correspondance entre Gauss et Humboldt et complète nos connaissances des recherches peu connues de Gauss. On présente une édition critique et commentée de la lettre. Резюме В сентябре 2019 года Ульриху Песлеру удалось обнаружить письмо Карла Фридриха Гаусса от 17 августа 1832 года, которое было адресовано Александру фон Гумбольдту. Это письмо, которое считалось утерянным, было написано Гауссом в самом начале его работ по изучению земного магнетизма. Гаусс признается в письме, что лишь полгода назад он решился заняться исследованиями в области, в которой до этого работал Гумбольдт. Важнейшими темами письма являются влияние температуры на магнитные свойства и способы магнетизирования игл и стержней. Письмо восполняет важный пробел в сохранившейся переписке Гаусса и Гумбольдта и дополняет наши знания о доселе неизвестных областях исследований Гаусса. Представлено критическое аннотированное издание письма.

description: In this contribution, we present some preliminary observational results from the completed ultra-deep survey of 21cm emission from neutral hydrogen at redshifts z=0.164-0.224 with the Westerbork Synthesis Radio Telescope. In two separate fields, a total of 160 individual galaxies has been detected in neutral hydrogen, with HI masses varying from 1.1x10^9 to 4.0x10^10 Msun. The largest galaxies are spatially resolved by the synthesized beam of 23x37 arcsec^2 while the velocity resolution of 19 km/s allowed the HI emission lines to be well resolved. The large scale structure in the surveyed volume is traced well in HI, apart from the highest density regions like the cores of galaxy clusters. All significant HI detections have obvious or plausible optical counterparts which are usually blue late-type galaxies that are UV-bright. One of the observed fields contains a massive Butcher-Oemler cluster but none of the associated blue galaxies has been detected in HI. The data suggest that the lower-luminosity galaxies at z=0.2 are more gas-rich than galaxies of similar luminosities at z=0, pending a careful analysis of the completeness near the detection limit. Optical counterparts of the HI detected galaxies are mostly located in the 'blue cloud' of the galaxy population although several galaxies on the 'red sequence' are also detected in HI. These results hold great promise for future deep 21cm surveys of neutral hydrogen with MeerKAT, APERTIF, ASKAP, and ultimately the Square Kilometre Array.

description: Large benthic foraminifera are major carbonate components in tropical carbonate platforms, important carbonate producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application of large benthic foraminifera in tropical coral reef environments has gained considerable momentum in recent years. These modern ecological assessments are often carried out by micropalaeontologists or ecologists with expertise in the identification of foraminifera. However, large benthic foraminifera have been under‐represented in favour of macro reef‐builders, for example, corals and calcareous algae. Large benthic foraminifera contribute about 5% to modern reef‐scale carbonate sediment production. Their substantial size and abundance are reflected by their symbiotic association with the living algae inside their tests. When the foraminiferal holobiont (the combination between the large benthic foraminifera host and the microalgal photosymbiont) dies, the remaining calcareous test renourishes sediment supply, which maintains and stabilizes shorelines and low‐lying islands. Geological records reveal episodes (i.e. late Palaeocene and early Eocene epochs) of prolific carbonate production in warmer oceans than today, and in the absence of corals. This begs for deeper consideration of how large benthic foraminifera will respond under future climatic scenarios of higher atmospheric carbon dioxide (pCO2) and to warmer oceans. In addition, studies highlighting the complex evolutionary associations between large benthic foraminifera hosts and their algal photosymbionts, as well as to associated habitats, suggest the potential for increased tolerance to a wide range of conditions. However, the full range of environments where large benthic foraminifera currently dwell is not well‐understood in terms of present and future carbonate production, and impact of stressors. The evidence for acclimatization, at least by a few species of well‐studied large benthic foraminifera, under intensifying climate change and within degrading reef ecosystems, is a prelude to future host–symbiont resilience under different climatic regimes and habitats than today. This review also highlights knowledge gaps in current understanding of large benthic foraminifera as prolific calcium carbonate producers across shallow carbonate shelf and slope environments under changing ocean conditions.

description: We study the Berezinskii-Kosterlitz-Thouless (BKT) transition of two-component Bose mixtures in two spatial dimensions. When phases of both components are decoupled, half-quantized vortex-antivortex pairs of each component induce two-step BKT transitions. On the other hand, when phases of the both components are synchronized through the inter-component Josephson coupling, two species of vortices of each component are bind to form a molecule, and in this case, we find that there is only one BKT transition by molecule-antimolecule pairs. Our results can be tested by two weakly-connected Bose systems such as two-component ultracold dilute Bose mixtures with the Rabi oscillation, and multiband superconductors.

Towards the undestanding of radial velocity pulsation in roAp stars

description: High-resolution spectroscopic time series of rapidly oscillating Ap stars show evidence for a co-existence of standing and running waves in their atmospheric layers. With the purpose of understanding these observations we have carried out a theoretical analysis of the pulsations in the outermost layers of these stars, starting from the simplest possible model that still retains all important physical ingredients. In our analysis we considered an isothermal atmosphere in a plane-parallel approximation. Moreover we assumed that in the region considered the magnetic pressure is much larger than the gas pressure and, consequently, that the magnetoacoustic wave has decoupled into its acoustic and magnetic components. Using the analytical solutions for the velocity components appropriate to this model we estimate the velocity component parallel to the line of sight averaged over the visible stellar disk. Fitting the latter to a function of the form Acos($σ$t+phase), with $σ$ the dimensionless oscillation frequency and t the dimensionless time, we derive the amplitude A and the phase for our model as function of height in the atmosphere.

description: This paper describes JANUS, a modular massively parallel and reconfigurable FPGA-based computing system. Each JANUS module has a computational core and a host. The computational core is a 4x4 array of FPGA-based processing elements with nearest-neighbor data links. Processors are also directly connected to an I/O node attached to the JANUS host, a conventional PC. JANUS is tailored for, but not limited to, the requirements of a class of hard scientific applications characterized by regular code structure, unconventional data manipulation instructions and not too large data-base size. We discuss the architecture of this configurable machine, and focus on its use on Monte Carlo simulations of statistical mechanics. On this class of application JANUS achieves impressive performances: in some cases one JANUS processing element outperfoms high-end PCs by a factor ~ 1000. We also discuss the role of JANUS on other classes of scientific applications.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

The Delayed Ionospheric Response to the 27‐day Solar Rotation Period Analyzed With GOLD and IGS TEC Data
Creators: name: Schmölter, Erik

Publisher: name: FID GEO

description: The delayed ionospheric response is analyzed for two well‐defined 27‐day solar rotation periods in the year 2019 with solar radio flux index F10.7 and Global‐scale Observations of the Limb and Disk (GOLD) data, like solar extreme ultraviolet (EUV) flux proxy, O/N2 column density ratio and peak electron density, as well as International Global Navigation Satellite System Service rapid high‐rate total electron content (TEC) map data. Although the correlation between GOLD solar EUV flux proxy and TEC is similar to the correlation between F10.7 and TEC, it is shown that the estimated delays based on GOLD data are in much better agreement with recent studies using EUV measurements compared to the delays based on F10.7 data. The GOLD peak electron density correlates well with TEC and allows insight to a local time interval when the ionosphere is not controlled by solar activity changes (17:00 LT to 21:00 LT). The present study investigates the impact of the solar activity (F10.7, GOLD EUV flux proxy) and O/N2 column density ratio on the ionospheric delay for two representative solar rotation periods. The capabilities of GOLD data for future research on the ionospheric response to the 27‐day solar rotation period are demonstrated and discussed. These results are crucial information for precise ionospheric models and forecasts.
description: Key Points: The good correlation of Global‐scale Observations of the Limb and Disk (GOLD) extreme ultraviolet (EUV) proxy and GOLD peak electron density with total electron content (TEC) allows detailed studies of the delayed ionospheric response. The ionospheric delay to the 27‐day solar rotation period based on GOLD EUV proxy and TEC confirms recent delay estimates of about 1 day. GOLD measurements at different times of the day allow insight into ionization, recombination and related accumulation processes.
