The different sensing units communicate with each other via wireless links and the seismic data are streamed in real-time to data centres at GFZ and the Central Asian Institute for Applied Geoscience (CAIAG) using internet. Since each sensing unit has...

Orthophoto and digital elevation model of zebra stripe area PP1, Paposo Fault, Chile

Dirk Hoffmeister
This dataset of an orthophoto and digital elevation model is derived from imagery captured by an unmanned aerial vehicle (type: DJI Phantom 4) of the zebra stripe area PP1, Paposo Fault, Chile. Imagery was captured on a cloud-free day in March 2018 in a manual flight pattern.

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...

Sofia-Katerina Kufner, Najibullah Kakar, Shokhruhk Murodkulov, Bernd Schurr, Xiaohui Yuan, Taher Rezai & Shekeb Shamal
The Pamir-Hindu Kush region of Tajikistan and NE Afghanistan stands out due to its worldwide unique zone of intense intermediate depth seismicity, accommodating frequent Mw 7+ earthquakes with hypocenters reaching down to 250 km depth. With this network we aim to collect data allowing to characterize the active deformation within the Hindu Kush mountains and the Tajik-Afghan basin at the northwestern tip of the India-Asia collision zone. The network consists 15 sites (14 stations in...

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...

GRACE Geopotential GAA Coefficients GFZ RL06

Henryk Dobslaw, Robert Dill & Christoph Dahle
Spherical harmonic coefficients that represent anomalous contributions of the non-tidal atmosphere to the Earth's mean gravity field during the specified timespan. This includes the contribution of atmospheric surface pressure over the continents, the static contribution of atmospheric pressure to ocean bottom pressure elsewhere, and the contribution of upper-air density anomalies above both the continents and the oceans. The anomalous signals are relative to the mean field from 2003-2014.

Supporting Information to: Resolving geophysical signals by terrestrial gravimetry: a time domain assessment of the correction-induced uncertainty

Michal Mikolaj, Marvin Reich & Andreas Güntner
This publication contains the supplementary data set to Mikolaj et al. "Resolving geophysical signals by terrestrial gravimetry: a time domain assessment of the correction-induced uncertainty" (2019, JGR-Solid Earth). The aim of the article is to estimate the uncertainty of terrestrial gravity corrections applied to resolve small-scale gravity effects. The uncertainty of the gravity corrections is assessed using various models of the tidal effect, large-scale hydrology, non-tidal ocean loading, and atmosphere. Taken into account are widely...

There were no changes to the simulation data.- On November 27, 2018 we republished simulation data for monthly variables swe, soilmoist and rootmoist for impact model PCR-GLOBWB due to an error in the units. Instead of reporting mass per area (kg/m2), values corresponded to mass flux...

VERSION HISTORY:- On April 10, 2018 we renamed some simulation files of impact models LPJ-GUESS, ORCHIDEE, JULES-UoE and VISIT, due to the correction of social scenario label “nosoc” for “varsoc”. For impact model VISIT, “nosoc” was relabeled to “pressoc”. These data caveats were documented in the ISIMIP website (ISIMIP2a Biomes: correction of scenario names in file names).- On October 17, 2018, we republished all simulation data for all biomes sector impact models to get the...

Supplement to “Synchronization of great subduction megathrust earthquakes: Insights from scale model analysis”

Matthias Rosenau, Illia Horenko, Fabio Corbi, Michael Rudolf, Ralf Kornhuber & Onno Oncken
This data set provides data from subduction zone earthquake experiments and analysis described in Rosenau et al. (2019). In the experiments analogue seismotectonic scale models of subduction zones characterized by two seismogenic asperities are used to study the interaction of asperities over multiple seismic cycles by means of static (Coulomb failure) stress transfer. Various asperity geometries (lateral/along-strike of the subduction zone distance and vertical/across-strike of the subduction zone offset) are tested on their effect on...
