Real‐Time Monitoring of Ionosphere VTEC Using Multi‐GNSS Carrier‐Phase Observations and B‐Splines
(Space Weather, 2021-10-11)Monitoring the Vertical Total Electron Content (VTEC) of the ionosphere is important for applications ranging from navigation to detection of space weather events. Therefore, emerging efforts have been made by several ... -
Reanalysis in Earth System Science: Toward Terrestrial Ecosystem Reanalysis
(Reviews of Geophysics, 2021-08-18)A reanalysis is a physically consistent set of optimally merged simulated model states and historical observational data, using data assimilation. High computational costs for modeled processes and assimilation algorithms ... -
Reassessing Eastern Mediterranean Tectonics and Earthquake Hazard From the 365 CE Earthquake
(AGU Advances, 2021-05-10)The hallmark of great earthquakes in the Mediterranean is the 21 July 365 CE earthquake and tsunami that destroyed cities and killed thousands of people throughout the Eastern Mediterranean. This event is intriguing because ... -
Recent evidence for warmer and drier growing seasons in climate sensitive regions of Central America from multiple global datasets
(International Journal of Climatology, 2021-08-09)Smallholder livelihoods throughout Central America are built on rain‐fed agriculture and depend on seasonal variations in temperature and precipitation. Recent climatic shifts in this highly diverse region are not well ... -
Rechnergestützte Bilddatenanalyse im Umweltmonitoring - zum Einsatz wissensbasierter Klassifikationen und Veränderungsanalysen mit handelsüblicher Fernerkundungssoftware
(Univ. Bochum, 2001)Die Arbeit untersucht, inwieweit die rechnergestützte Analyse digitaler Luft- und Satellitenbilddaten bestehende Verfahren im Umweltmonitoring optimieren kann. Zunächst wird der Stand der Forschung im Bereich "Fernerkundung ... -
Reconciling Canopy Interception Parameterization and Rainfall Forcing Frequency in the Community Land Model for Simulating Evapotranspiration of Rainforests and Oil Palm Plantations in Indonesia
(Journal of Advances in Modeling Earth Systems, 2019)By mediating evapotranspiration processes, plant canopies play an important role in the terrestrial water cycle and regional climate. Substantial uncertainties exist in modeling canopy water interception and related ... -
Reconstructing the slip velocities of the 1202 and 1759 CE earthquakes based on faulted archaeological structures at Tell Ateret, Dead Sea Fault
(Journal of Seismology, 2021-06-03)Archaeological structures built across active faults and ruptured by earthquakes have been used as markers to measure the amount of displacement caused by ground motion and thus to estimate the magnitude of ancient ... -
Reconstruction of oceanic currents and climate change in the Transkei Basin, South African gateway
(Univ. Bremen, 2007)Reflection seismics, sediment drifts, bottom currents. - The region south of South Africa has been a crucial gateway for large scale Thermohaline Circulations since late Eocene times. Here, three of the most important ... -
Reconstruction of the Basin‐Wide Sea‐Level Variability in the North Sea Using Coastal Data and Generative Adversarial Networks
(Journal of Geophysical Research: Oceans, 2020-12-03)We present an application of generative adversarial networks (GANs) to reconstruct the sea level of the North Sea using a limited amount of data from tidal gauges (TGs). The application of this technique, which learns how ... -
