Eyjafjallajökull satellite observations
<p>Satellite observations based on "Hourly non-gridded volcanic ash properties retrieved from SEVIRI measurements for the Eyjafjallajökull 2010 eruption" (Kylling and Sollum 2020, CC BY-SA 4.0, 10.5281/zenodo.3830363). The data has been regridded using fimex 1.4.2 to match the simulation domain MACC14 and thus be colocated with "Three-hourly gridded volcanic ash emissions for the Eyjafjallajökull 2010 eruption" (Brodtkorb et al., 2020, 10.5281/zenodo.3818196). These two datasets are used as input for the volcanic ash inversion routines in "metno/VolcanicAshInversion" (Brodtkorb, 2020, 10.5281/zenodo.3818001)</p> <p> </p> <p> </p>

Volatile organic compound analysis, a new tool in the quest for preterm birth prediction – an observational cohort study
<p>Vaginal swabs were taken in pregnancy in high risk asymptomatic women attending a preterm prevention clinic. Women in the study attended the clinical due to a history of preterm birth or midtrimester pregnancy loss, or due to a history of cervical surgery. Individualised management plans were made depending upon individual patient risk factors. During their attendance to the clinic vaginal swabs were taken for VOC analysis. Swabs were taken between 15 and 28 weeks gestation. Women consented to vaginal swabs at each of their visits to the clinic. The dataset contains GC-IMS VOC data from a G.A.S. GC-IMS and includes a Spreadsheet of demographics.</p>

Termitotrox icarus sp. nov. (Coleoptera: Scarabaeidae): a new termitophilous beetle from Myanmar with observations of carrying behavior by host termites
<p>Abstract. A new species of scarab beetle, Termitotrox icarus sp. nov., is described from central Myanmar, being the third representative of the genus Termitotrox Reichensperger, 1915 from the Indo-Chinese Subregion of the Oriental Region. The majority of the type series was collected from the walls of fungus garden chambers built in the nests of the termite Odontotermes proformosanus Ahmad, 1965. Termitotrox icarus sp. nov. can be easily distinguished from the known Termitotrox as it possesses wing-shaped trichomes on the elytra, the more elongate habitus shape in dorsal view, the basomedian section of pronotum not protruding backwards, a pair of distinct costae on the pronotal basomedian section strongly developed, a median costa on anterior pronotal margin strongly develo- ped, the elytral striae narrower than interstriae, the lack of trichomes at the base of elytral sutural stria, and a mid-range body length of 1.5–1.9 mm. The ‘carrying behavior’ by the host termites is reported for the first time for Termitotrox and a strategy for the dispersal of flightless termitophilous scarabs is hypothesized.</p>

<p>This database contains wind measurements, at the ecohydrological monitoring site of “El Palmar” state reserve (21.0293 ° N, 90.0637 ° W; 1.86 mamsl), Yucatan, Mexico. The acquisition of these data was performed from December 7th 2016 to August 21st 2019, in a 22 m Eddy-Covariance tower, using a 3D sonic anemometer (WindMaster Pro, Gill Instruments, UK) connected to a LI-7550 Interface Unit. Data was processed using the EddyPro 6.2.2 software, and are presented in averages of every half hour. A quality control was performed on the data.</p> <p>For more information visit: http://ocse.mx/en/experimento/torre-de-flujos-palmar</p>

DATA of "Resolving the 2D temporal evolution of subglacial water flow with dense seismic array observations."
<p>The data set contains all data presented in the paper: <strong>Observing the subglacial hydrology network and its dynamics with a dense seismic array</strong> published in PNAS ( <a href="https://doi.org/10.1073/pnas.2023757118">https://doi.org/10.1073/pnas.2023757118</a> )</p> <p>See our online presentation of this dataset: https://meetingorganizer.copernicus.org/EGU2020/EGU2020-10710.html.</p> <p>The present data and code concerns the source location obtained with matched-field-processing analysis and the hydraulic potential calculation (Shreve, R. L. Movement of Water in Glaciers. <em>J. Glaciol.</em> <strong>11</strong>, 205–214 (1972)).</p> <p>We perform source location over 1-sec long signal segment of the vertical component only. We filter the signal within the [3-7] Hz frequency range and coherently apply the MFP each 0.1 Hz within this range. To maximize our algorithm efficiency and minimize computational costs we use a gradient-based minimization algorithm (Nelder-Mead optimization) to converge to the best match between the trial and the observed phase delays rather than an exhaustive grid-search exploration. The convergence criterion is reached when the variance of values obtained over the last 5 iterations of the optimization is smaller than 1e<sup>-2</sup> with a maximum of 3000 iterations. Our 29 different starting points used for optimization are located 250 m below the glacier surface and they uniformly cover an area of 800 x 800 m<sup>2</sup> centered on the array. We set the initial velocity to 1800 m.sec <sup>-1</sup>. The 29 punctual locations found per signal segment (1 sec) after convergence are located all in the same place if a clear global convergence exists (i.e. high MFP output) or at up to 29 different locations if up to 29 local minima exist (i.e. low MFP output).</p> <p>Timeseries of physical quantities can be found here <a href="https://doi.org/10.5281/zenodo.3701520">https://doi.org/10.5281/zenodo.3701520</a></p> <p>Spatial observations acquired during the same period can be found here <a href="https://doi.org/10.5281/zenodo.3971815">https://doi.org/10.5281/zenodo.3971815</a></p> <p> </p> <p>The RESOLVE project has been supported by a grant from LabEx OSUG@2020 (Investissement d’avenir – ANR10LABX56) and by the IDEX Université Grenoble Alpes.
