This project is a continuation of project F funded in the first phase of the DFG Research Group CAOS, where we evaluated the potential of different ground-based geophysical techniques for exploring hydrological systems regarding subsurface structures, characteristics, and processes. Building up on the results of this project, we now focus on further developing selected geophysical techniques (timelapse GPR imaging) for deepening our understanding of hydrological processes at the plot and hillslope scale. In addition, we propose to systematically evaluate modem remote sensing techniques because they cun-ently represent the only means to efficiently explore larger areas or entire catchments. Here, we focus on a combination of full-waveform laserscanning and hyperspectral imaging because they can provide detailed Information regarding geometrical and physical properties of earth's surface, respectively. To link remote sensing with point/plot/hillslope scale data as provided by geophysics and conventional hydrological field techniques, we believe that further methodological innovations are needed. For example, we plan to establish a unique field laboratory to better understand the responses of geophysical and remote sensing techniques to different natural and artificial hydrological events and to develop exploration strategies advancing the applicability of geophysics and remote sensing for hydrological applications at a variety of spatial scales.
GFZ Data Services is a repository for research data and scientific software across the Earth System Sciences, hosted at GFZ. The curated data are archived, persistently accessible and published with digital object identifier (DOI). They range from large dynamic datasets from global monitoring networks with real-time aquisition, to international services in geodesy and geophysics, to the full suite of small and highly heterogeneous datasets collected by individual researchers or small teams ("long-tail data"). In addition to the DOI registration and data archiving itself, GFZ Data Services team offers comprehensive consultation by domain scientists and IT specialists. Among others, GFZ Data Services is data publisher for the IAG Services ICGEM, IGETS and ISG (IAG = Int. Association for Geodesy; ICGEM = Int. Center for Global Earth Models; IGETS = Int. Geodynamics and Earth Tide Service; ISG = Int. Service for the Geoid), the World Stress Map, INTERMAGNET, GEOFON, the Geophysical Instrument Pool Potsdam GIPP, TERENO, EnMAP Flight Campaigns, the Potsdam Institute for Climate Impact Research PIK, the Specialised Information Service for Solid Earth Geosciences (FID GEO) and hosts the GFZ Catalogue for the International Generic Sample Number IGSN.

HALO-DB is the web platform of a data retrieval and long-term archive system. The system was established to hold and to manage a wide range of data based on observations of the HALO research aircraft and data which are related to HALO observations. HALO (High-Altitude and LOng-range aircraft) is the new German research aircraft (German Science Community (DFG)). The aircraft, a Gulfstream GV-550 Business-Jet, is strongly modified for the application as a research platform. HALO offers several advantages for scientific campaigns, such as its high range of more than 10000 km, a high maximum altitude of more than 15 km, as well as a relatively high payload.
Supplementary information to the manuscript “Seismoacoustic analysis of a Falcon 9 rocket stage re-entry over central Europe on 19 February 2025” by Hupe et al. (2026). Results of the Progressive Multi-Channel Correlation (PMCC) processing for far-field infrasound stations, displayed in Figure 7 of the manuscript (IS26 in Germany, NRSI in Norway, HFSI in Sweden). The netcdf files contain the following detection parameters of single arrivals: Time, duration, back-azimuth, apparent velocity, frequency, family identifier. Data format: One .nc file for each station.
Die Datenebene enthält Informationen zu Messgebieten, Profillinien und Messkampagnen geophysikalischer Untersuchungen entsprechend der Fachbereiche getrennt für Geoelektrik, Gravimetrie, Geomagnetik und Seismik. Geoelektrik: Übersicht über lokale Messgebiete, die von verschiedenen Firmen bearbeitet, sowie Untersuchungen, die vom LAGB beauftragt oder selbst durchgeführt wurden. Vor 1990 betreffen die von Firmen durchgeführten Untersuchungen zumeist Messungen des VEB Geophysik Leipzig, nach 1990 Messungen verschiedener Ingenieurbüros, die nach Lagerstättengesetz/Geologiedatengesetz an das LAGB gemeldet wurden. Seismik: Die Profilanlage seismischer Messungen ist unterteilt in 2D-reflexionsseismische Messungen zur Erkundung geologischer Strukturen und der Rohstoffexploration in bis ca. 5 km Tiefe sowie die Messungen der Refraktionsseismik und Weitwinkelreflexionsseismik, welche den Aufbau der Erdkruste in bis zu 40 km Tiefe untersuchen. Die tiefenseismischen Profile werden weiterhin durch die eingesetzten Messmethoden unterschieden. Untersuchungsgebiete reflexionsseismischer 3D-Messungen markieren Gebiete der detaillierten Exploration von mit Hilfe mehrerer Quellen gleichzeitig angeregter seismischer Signale, welche an flächenhaft ausgebrachten Geophonen registriert werden. Gravimetrie und Geomagnetik: Aufgeführt sind die Messgebietsumrisse und Informationen der Regionalmessungen in Sachsen-Anhalt.
The dataset includes the locations of OBS stations (Ocean Bottom Seismometers) operated in the German Bight during cruise MSM100 with R.V. Maria S. Merian. The time interval from 13.05.2021 to 15.05.2021 has been analysed in a phase without airgun operation for passive recording with 4.5 Hz geophones. Furthermore, the dataset contains locations of 3 broadband OBS systems which were operated during an experiment at the Darss ramp in the German Baltic Sea. The records were analysed in the time interval 23.01.2018 to 01.04.2018.

This dataset consists of data products derived from broadband signal detection lists that have been processed for the certified infrasound stations of the International Monitoring System. More specifically, within the CTBT-relevant infrasound range (around 0.01-4 Hz), this dataset covers higher frequencies (1-3 Hz) and is therefore called the ‘hf’ product. The temporal resolution (time step and window length) is 5 min. For processing the infrasound data, the Progressive Multi-Channel Correlation (PMCC) array processing algorithm with a one-third octave frequency band configuration between 0.01 and 4 Hz has been used. The detected signals from the most dominant directions in terms of number of arrivals within a time window and the product-specific frequency range are summarized at predefined time steps. Along with several detection parameters such as the back azimuth, apparent velocity, or mean frequency, additional quantities for assessing the relative quality of the detection parameters are provided. The dataset is available as a compressed .zip file containing the yearly data products (.nc files, NetCDF format) of all certified stations (since 2003). Further information on the processing and details about the open-access data products can be found in: Hupe et al. (2022), IMS infrasound data products for atmospheric studies and civilian applications, Earth System Science Data, doi:10.5194/essd-14-4201-2022
