Evaluating the GECCO3 1948–2018 ocean synthesis – a configuration for initializing the MPI-ESM climate model
(Quarterly Journal of the Royal Meteorological Society, 2020)
The paper describes an update of the GECCO (German contribution to the Estimating the Circulation and Climate of the Ocean project) ocean synthesis, now in its version 3, and provides an evaluation of the results with ... -
Evaluating the role of coastal hypoxia on the transient expansion of microencruster intervals during the early Aptian
; Huck, Stefan; Heimhofer, Ulrich; Bodin, Stéphane; Weyer, Stefan; ; Roebbert, Yvonne; (Lethaia, 2020-11-26)
Worldwide, a growing number of modern coastal marine ecosystems are increasingly exposed to suboxic‐ or even anoxic conditions. Low seawater oxygen levels trigger significant ecosystem changes and may result in mass mortality ... -
Evaluating urban micrometeorites as a research resource—A large population collected from a single rooftop
; ; (Meteoritics & Planetary Science, 2021-07-27)
We report the recovery and characterization of a new urban micrometeorite collection derived from the rooftop of an industrial building in Germany. We identified 315 micrometeorites (diameter: 55–515 µm, size peak: ˜150 µm, ... -
Evaluation and application of GPS and altimetry data over central Dronning Maud Land, Antarctica - annual elevation change, a digital elevation model, and surface flow velocity
(Univ. Bremen, 2009)The polar ice sheets are unique paleoclimatic archives and play an important role in recent and future climate. The melting of the big freshwater reservoirs will not only increase the global sea level, but will also influence ... -
Evaluation and communication of pluvial flood risks in urban areas
; (Wiley Interdisciplinary Reviews: Water, 2019)
The increase of pluvial flooding has long been discussed to be a most probable outcome of climate change. This has raised the question of necessary consequences in the design of urban drainage systems in order to secure ... -
Evaluation of a Microwave Emissivity Module for Desert Regions With CMEM
; (Earth and Space Science, 2019)
To overcome deficiencies of current state-of-the-art L-band microwave emission models a microwave emissivity parameterization for desert regions, as derived by Grody and Weng (2008) using dense media theory, has been ... -
Evaluation of CO2 injection processes in geological formations for site screening

Evaluation of FESOM2.0 Coupled to ECHAM6.3: Preindustrial and HighResMIP Simulations
; ; ; Scholz, P.; ; Barbi, D.; Cabos, W.; ; Harig, S.; ; ; ; ; ; ; Rakowsky, N.; ; ; ; ; Streffing, J.; ; ; Yang, H.; (Journal of Advances in Modeling Earth Systems, 2019)
A new global climate model setup using FESOM2.0 for the sea ice-ocean component and ECHAM6.3 for the atmosphere and land surface has been developed. Replacing FESOM1.4 by FESOM2.0 promises a higher efficiency of the new ... -
Evaluation of precipitation datasets against local observations in southwestern Iran
; ; ; ; (International Journal of Climatology, 2020)
This study provides a comprehensive evaluation of a great variety of state-of-the-art precipitation datasets against gauge observations over the Karun basin in southwestern Iran. In particular, we consider (a) gauge-interpolated ... -
Evaluation of the effects of shaking intensity on the process of methylene blue discoloration by metallic iron.
; Kurth, A.-M. F.; (Journal of hazardous materials, 2009-09-30)
The term mixing (shaking, stirring, agitating) is confusing because it is used to describe mass transfer in systems involving species dissolution, species dispersion and particle suspension. Each of these mechanisms requires ... -
Evaluation of the representative elementary volume (REV) of a fractured geothermal sandstone reservoir
Müller, Christian; Siegesmund, Siegfried; (Environmental Earth Sciences, 2010)
The objective of this study is to evaluate a representative elementary volume (REV) in a fractured geothermal sandstone reservoir in Germany using the discrete fracture network (DFN) model approach. Due to the lack of in ... -
Evaluation of transmissivity in a fractured aquifer—the Nyanzari wellfield, Burundi
(Grundwasser, 2021-12-08)Due to population growth, the city of Gitega in the central part of Burundi is lacking drinking water. Therefore, the national urban water supply company decided to expand the Nyanzari wellfield by drilling additional ... -

Evaporation Study Based on Micromodel Experiments: Comparison of Theory and Experiment
; ; ; ; ; ; ; (Water Resources Research, 2019)
Abstract Evaporation—a key process for water exchange between soil and atmosphere—is controlled by internal water fluxes and surface vapor fluxes. Recent studies demonstrated that the dynamics of the water flow in corners ... -
Evidence for a Waalian thermomer pollen record from the research borehole Heidelberg UniNord, Upper Rhine Graben, Baden-Württemberg
(E&G – Quaternary Science Journal; Vol.57, No. 3-4)Eine Pollensukzession aus der Bohrung Heidelberg UniNord im Oberrheingraben kann mit der bisher selten nachgewiesenen Waal-Warmzeit verknüpft werden. Das wohl nicht vollständig erfasste Thermomer reflektiert eine angedeutete ... -
Evidence for local carbon‐cycle perturbations superimposed on the Toarcian carbon isotope excursion
; Ossa Ossa, Frantz; Wille, Martin; Schurr, Simon; Saussele, Mario‐Erich; Schmid‐Röhl, Annette; (Geobiology, 2020-08-12)
A Jurassic negative carbon isotope excursion (CIE), co‐evolved with Toarcian Oceanic Anoxic Event (OAE) at ~183 Ma, is suggested to be linked to a global carbon‐cycle perturbation and is well documented for Toarcian ... -
Evidence for Secondary Ice Production in Southern Ocean Maritime Boundary Layer Clouds
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2022-08-16)
Maritime boundary‐layer clouds over the Southern Ocean (SO) have a large shortwave radiative effect. Yet, climate models have difficulties in representing these clouds and, especially, their phase in this observationally ... -
Evidence of Presence of the Eltville Tuff Layer in Dutsch and Belgian Limbourg and the Consequences for the Loess Stratigraphy
(E&G – Quaternary Science Journal; Vol.33, No. 1)Anfang 1979 ist zum ersten Male in den Niederlanden ein vulkanischer Tuff in den Lößablagerungen von Süd-Limburg gefunden worden (Meijs 1980a). Auf Grund der stratigraphischen Lage, des makroskopischen Aussehens und der ... -
