A Binomial Stochastic Framework for Efficiently Modeling Discrete Statistics of Convective Populations
; (Journal of Advances in Modeling Earth Systems, 2021-03-23)
Understanding the coupling between convective clouds and the general circulation, as well as addressing the gray zone problem in convective parameterization, requires insight into the genesis and maintenance of spatial ... -
A Burmese amber fossil of Radula (Porellales, Jungermanniopsida) provides insights into the Cretaceous evolution of epiphytic lineages of leafy liverworts
(Fossil Record, 2017)DNA-based divergence time estimates suggested major changes in the composition of epiphyte lineages of liverworts during the Cretaceous; however, evidence from the fossil record is scarce. We present the first Cretaceous ... -
A chronological and palaeoenvironmental re‐evaluation of two loess‐palaeosol records in the northern Harz foreland, Germany, based on innovative modelling tools
; ; ; ; (Boreas, 2021-02-04)
The continuing development of analytical methods for investigating sedimentary records calls for iterative re‐examination of existing data sets obtained on loess‐palaeosol sequences (LPS) as archives of palaeoenvironmental ... -
A cold pool perturbation scheme to improve convective initiation in convection‐permitting models
; (Quarterly Journal of the Royal Meteorological Society, 2021-05-04)
Cold pools originate from evaporation in precipitating downdraughts and spread as density currents at the surface. Vertical motion at the leading edge of the cold pool is an important trigger for new convective cells in ... -
A Combined Cosmogenic Nuclides Approach for Determining the Temperature‐Dependence of Erosion
; (Journal of Geophysical Research: Earth Surface, 2022-04-07)
Physical weathering in cold, steep bedrock hillslopes occurs at rates that are thought to depend on temperature, but our ability to quantify the temperature‐dependence of erosion remains limited when integrating over ... -
A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
; ; (Journal of Geophysical Research: Space Physics, 2021-03-16)
In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of ... -
A combined structural interpretation based on seismic data and 3-D gravity modeling in the northern Puna/Eastern Cordillera, Argentina
(Selbstverlag Fachbereich Geowissenschaften Freie Universität Berlin, 1998)Die Andenkordillere entstand entlang des westlichen Randes von Südamerika aufgrund der Subduktion der ozeanischen Nazca-Platte unter die kontinentale Südamerikaplatte seit dem Jura. Als solche werden die Anden als ein ... -
A comparative study of the diagenesis in diapir-influenced reef atolls and a fault block reef platform in the Late Albian of the Vasco-Cantabrian Basin
(Reef diagenesisReef diagenesis, 1986)

A comparison of Bayesian hierarchical space-time models for earthquake data
(2004)Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ... -
A Comparison of Radial Diffusion Coefficients in 1‐D and 3‐D Long‐Term Radiation Belt Simulations
; ; ; ; (Journal of Geophysical Research: Space Physics, 2021-08-13)
Radial diffusion is one of the dominant physical mechanisms driving acceleration and loss of radiation belt electrons. A number of parameterizations for radial diffusion coefficients have been developed, each differing in ... -
A Comparison of the Location of the Mid‐Latitude Trough and Plasmapause Boundary
; ; (Journal of Geophysical Research: Space Physics, 2021-04-15)
Abstract: We have compared the location of the mid‐latitude trough observed in two dimensional vertical total electron content (vTEC) maps with four plasmapause boundary models, Radiation Belt Storm Probes (RBSP) observations, ... -
A concept for a regional coastal zone mission

A contribution to characterizing and calibrating the pointing control system of the SOFIA telescope
(Univ. Stuttgart, 2009)SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory that will study the universe in the infrared spectrum. A Boeing 747-SP aircraft will carry a 2.5 m telescope designed to make sensitive ... -
A Critical Evaluation of Deep Blue Algorithm Derived AVHRR Aerosol Product Over China
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2019)
The Deep Blue (DB) aerosol retrieval algorithm has recently been applied to Advanced Very High Resolution Radiometer (AVHRR) data to produce a first version (V001) of a global aerosol optical thickness (AOT) data set. In ... -
A critical review on the process of contaminant removal in Fe0-H2O systems.
(Environmental technology, 2008-08-01)
A central aspect of the contaminant removal by elemental iron materials (Fe0 or Fe0 materials) is that reduction reactions are mediated by the iron surface (direct reduction). This premise was introduced by the pioneers ... -
A Data-Driven Framework to Characterize State-Level Water Use in the United States
;; ; ; (Water Resources Research, 2020)
Access to credible estimates of water use is critical for making optimal operational decisions and investment plans to ensure reliable and affordable provisioning of water. Furthermore, identifying the key predictors of ... -
