Software supplement to "Variation to Individual Location Radiance in VIIRS DNB Monthly Composite Images"

Jacqueline Coesfeld & Christopher Kyba
This set of Python-code is used to analyse the variation of VIIRS DNB nighttime imagery. The code is inline documented and the readme provides information on what is needed to run the code, and what order to run it in. These routines were used to produce the data and plots in the paper: Variation of Individual Location Radiance in VIIRS Day/Night Band Monthly Composite Images (Coesfeld et al. 2018). Monthly VIIRS DNB data can be...

Surface energy balance at a grassland site in Luxembourg modelled by three structurally different evapotranspiration schemes

Maik Renner, Hans-Dieter Wizemann, Claire Brenner, Kaniska Mallick, Ivonne Trebs, Volker Wulfmeyer, Karsten Schulz & Axel Kleidon
This dataset provides half-hourly model output of sensible and latent heat fluxes simulated by three structurally different evapotranspiration schemes for a temperate grassland site in Luxembourg. All models use surface energy and meteorological observations as input. The observational data were collected during a field campaign in June and July 2015 and are distributed as complementary dataset by Wizemann et al., 2018. Two models are based on a parameterization of the sensible heat flux (OSEB, TSEB;...

ITSG-Grace2018 - Monthly, Daily and Static Gravity Field Solutions from GRACE

Torsten Mayer-Gürr, Saniya Behzadpur, Matthias Ellmer, Andreas Kvas, Beate Klinger, Sebastian Strasser & Norbert Zehentner
The ITSG-Grace2018 gravity field model is the latest GRACE-only gravity field model computed at Graz University of Technology, providing unconstrained monthly and regularized daily solutions as well as a long-term static field. For each month of the observation period, sets of spherical harmonic coefficients for different maximum degrees (60, 96, 120) were estimated without applying any regularization. In order to resolve high-frequency gravity field variations as detailed as possible, a set of spherical harmonic coefficients...

The EMCA landslide catalog of Central Asia covers mostly western and northern Kyrgyzstan as well as Tajikistan's Region of Republican Subordination. The catalog is a summary (point locations) of the documented landslides between 1954 and 2009, which are collected by the Central Asian Institute for Applied Geosciences through geological surveys (field campaigns) on single sites close to urban areas in order to mitigate landslide risk. The catalog is presented in identical .csv and NetCDF (.nc)...

A global gridded data set on tillage - R-code

Vera Porwollik, Susanne Rolinski & Christoph Müller
Tillage is a central element in agricultural soil management and has direct and indirect effects on processes in the biosphere. Effects of agricultural soil management can be assessed by soil, crop, and ecosystem models but global assessments are hampered by lack of information on soil management systems. This study presents a classification of globally relevant tillage practices and a global spatially explicit data set on the distribution of tillage practices for around the year 2005....

A global gridded data set on tillage

Vera Porwollik, Susanne Rolinski & Christoph Müller
Tillage is a central element in agricultural soil management and has direct and indirect effects on processes in the biosphere. Effects of agricultural soil management can be assessed by soil, crop, and ecosystem models but global assessments are hampered by lack of information on type and spatial distribution. This dataset is the result of a study on global classification of tillage practices and the spatially explicit mapping of crop-specific tillage systems for around the year...

Geochemical data of impactites of the Ries impact structure, Germany

Susann Siegert & Lutz Hecht
The Ries impact structure in Southern Germany is one of the best-preserved impact structures on Earth. Melt-bearing impact breccia appears in a variety of well accessible exposures around the inner ring up to 10 km beyond the crater rim (so-called outer suevite) overlying a ballistically ejected lithic breccia (so-called ‘Bunte Breccia’). Occasionally individual melt bombs occur in the ‘Bunte Breccia’. Coherent impact melt rock outside the inner crater is located in the eastern megablock zone...

DEEP-TEE Phase 1

J. R. R. Ritter, B. Schmidt, C. Haberland & M. Weber
A seismological experiment was started in July 2014 in and around the East Eifel Volcanic Field, Germany. Following two unusually deep micro-earthquakes in September 2013 (about 40 km depth) a seismic network was installed to record more local seismic events in order to better understand the seismicity and dynamics of this region. Ten recording stations of the GFZ GIPP (Geophysical Instrument Pool Potsdam at Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences) and three...

Slivisu: A visual analytics tool to validate simulation models against collected data

Andrea Unger, Daniela Rabe, Volker Klemann, Daniel Eggert & Doris Dransch
The validation of a simulation model is a crucial task in model development. It involves the comparison of simulation data to observation data and the identification of suitable model parameters. SLIVISU is a Visual Analytics framework that enables geoscientists to perform these tasks for observation data that is sparse and uncertain. Primarily, SLIVISU was designed to evaluate sea level indicators, which are geological or archaeological samples supporting the reconstruction of former sea level over the...

Hall current densities derived from CHAMP scalar magnetic field data during six magnetic storms 2003 and 2005

Patricia Ritter
This dataset comprises profiles of Hall ionospheric current densities derived from scalar magnetic field data measured from the CHAMP satellite during six magnetic storms. The Hall currents are intense electric currents that flow horizontally above the earth’s surface in the polar region and perpendicular to the geomagnetic field. They peak at approximately ± 80° of geomagnetic latitude. Together with the field-aligned currents they form part of the ionospheric current system. During enhanced geomagnetic activity the...

Supraglacial Debris Cover

Dirk Scherler, Hendrik Wulf & Noel Gorelick
This dataset is supplementary to the article of Scherler et al. (submitted), in which the global distribution of supraglacial debris cover is mapped and analyzed. For mapping supraglacial debris cover, we combined glacier outlines from the Randolph Glacier Inventory (RGI) version 6.0 (RGI consortium, 2017) with remote sensing-based ice and snow identification. Areas that belong to glaciers but that are neither ice nor snow were classified as debris cover. This dataset contains the outlines of...

Sven Fuchs, Hans-Jürgen Förster, Kathleen Braune & Andrea Förster
This data set compiles the raw data that were used to calculate the bulk thermal conductivity (λb) of low-porosity igneous rocks from modal mineralogy, porosity, and nature of saturation fluid. It compliments a paper by Fuchs et al. (2018) to which it represents supplementary material. The paper reports the result of seeking out the mixing model(s) providing the best match between measured (λb.meas) and calculated bulk thermal conductivity (λb.calc) for low-porous igneous rocks.

Data supplement to: Laser ablation in situ silicon stable isotope analysis of phytoliths

Daniel A. Frick, Jan A. Schuessler, Michael Sommer & Friedhelm Von Blanckenburg
Silicon is a beneficial element for many plants, and is deposited in plant tissue as amorphous bio-opal (phytoliths). The biochemical processes of uptake and precipitation induce isotope fractionation: the mass-dependent shift in the relative abundances of the stable isotopes of silicon. At the bulk scale, the silicon isotope composition reported as δ30Si span from -2 to +6 ‰. To further constrain these variations, at the scale of individual phytolith fragments we applied in situ femtosecond...
