(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The absence of aggregated uncertainty measures restricts the assessment of uncertainty in hydrological simulation. In this work, a new composite uncertainty measure is developed to evaluate the complex behaviors of uncertainty ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)Constraining the thermal evolution of the Arctic Ocean is hampered by notably sparse heat flow measurements and a complex tectonic history. Previous results from the Lomonosov Ridge in the vicinity of the North Pole, and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We study attenuation of free waves in the homogeneous ocean. Using the Cauchy–Riemann relations and then energy equation, we derive a novel equation that relates temporal and spatial decay to the energy dissipation in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Coffinite (USiO4) and thorite (ThSiO4) are conspicuous radiogenic silicates in the geonomy. They form U1−xThxSiO4 (uranothorite) solid solutions in zircon-type phase. Investigating the phase-evolution of these minerals is ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Climate change and anthropogenic activity are the primary drivers of water cycle changes. Hydrological droughts are caused by a shortage of surface and/or groundwater resources caused by climate change and/or anthropogenic ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)One critical question for water security and sustainable development is how water quality responses to the changes in natural factors and human activities, especially in light of the expected exacerbation in water scarcity. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The conceptual hydrologic model has been widely used for flood forecasting, while long short-term memory (LSTM) neural network has been demonstrated a powerful ability to tackle time-series predictions. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract To address groundwater issues, it is often necessary to develop geological and hydrogeological models. Combining geological, geophysical and hydrogeological data available on a site to build such models is often ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Multiple-point statistics algorithms allow modeling spatial variability from training images. Among these techniques, the Direct Sampling (DS) algorithm has advanced capabilities, such as multivariate simulations, treatment ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2023)Soil moisture drought, as one of the most important drought categories, is determined by both water supply (e.g., precipitation) and demand (e.g., potential evapotranspiration). To shed light on the underlying mechanisms ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Devonian has long been a problematic period for paleomagnetism. Devonian paleomagnetic data are generally difficult to interpret and have complex partial or full overprints– problems that arise in data obtained from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Estimates for equilibrium climate sensitivity from current climate models continue to exhibit a large spread, from 2.1 to 4.7 K per carbon dioxide doubling. Recent studies have found that the treatment of precipitation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Sensitivity analysis is a commonly used technique in hydrological modeling for different purposes, including identifying the influential parameters and ranking them. This paper proposes a simplified ...
-
A Process Study on Thinning of Arctic Winter Cirrus Clouds With High‐Resolution ICON‐ART Simulations (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In this study, cloud‐resolving simulations of a case study for a limited area of the hibernal Arctic were performed with the atmospheric modeling system ICON‐ART (ICOsahedral Nonhydrostatic‐Aerosol and Reactive Trace gases). ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We document model updates and present and discuss modeling and validation results from a further developed production-tagged aerosol module, OsloAero5.3, for use in Earth system models. The aerosol module has in this study ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic eruptions (Chaiten 2008, Cordón ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)The formation of a global network of plate boundaries surrounding a mosaic of lithospheric fragments was a key step in the emergence of Earth’s plate tectonics. So far, propositions for plate boundary formation are regional ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)nterpretations of the pre-Caledonian rifted margin of Baltica commonly reconstruct it as a simple, tapering, wedge-shaped continental margin dissected by half graben, with progressively more rift-related magmas towards the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The extensive use of per- and polyfluorinated alkyl substances (PFAS) has resulted in many environmental point and diffuse sources. Identifying the source responsible for a pollution hot spot is vital for assessing remediation ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)A reasonable assessment of the hydrological regime alteration is a prerequisite for river utilization, restoration, and protection. The hydrological alteration is quantified as changes in different indicators (IHAs) ...
