Continental weathering intensity during the termination of the Marinoan Snowball Earth: Mg isotope evidence from the basal Doushantuo cap carbonate in South China

, 2020
The Neoproterozoic global glaciations (720–635 Ma) represent the most severe icehouse climatic conditions in Earth's history, collectively known as the ‘Snowball Earth events’. The ‘Snowball Earth’ hypothesis (Hoffman et al.

Geochemistry of cretaceous fine-grained siliciclastic rocks from Upper Mundeck and Logbadjeck Formations, Douala sub-basin, SW Cameroon: Implications for weathering intensity, provenance, paleoclimate, redox condition, and tectonic setting

Journal of African Earth Sciences, 2019
The chemical composition of the Upper Mundeck Formation (UMF) and Logbadjeck Formation (LF) from the Douala sub-basin (Cameroon) has been investigated to determine their provenance, the influence of the weathering, the paleoclimate, and the redox ...

Geochemical Characterization of Beach Sediments of Miri, NW Borneo, SE Asia: Implications on Provenance, Weathering Intensity, and Assessment of Coastal Environmental Status

Coastal Zone Management, 2019
The bulk chemistry of coastal sediments is governed by the geochemical nature of the river basin, the physical and chemical processes involved during weathering, and transportation of these sediments to the coastal zone and the post-depositional ...

FIND: A Synthetic weather generator to control drought Frequency, Intensity, and Duration

Environmental Modelling & Software, 2023
Water systems worldwide are experiencing climate change-induced shifts in drought properties like frequency, intensity, and duration, affecting water security and reliability. To develop and test effective drought preparedness plans, researchers often use synthetic weather generators to create hydrological scenarios that explore drought variability ...

Influence of weather and climate on subjective symptom intensity in atopic eczema

International Journal of Biometeorology, 2001
The frequent clinical observation that the course of atopic eczema, a skin disease involving a disturbed cutaneous barrier function, is influenced by climate and weather motivated us to analyse these relationships biometrically. In the Swiss high-mountain area of Davos the intensity of itching experienced by patients with atopic eczema was evaluated ...

A scheme to detect the intensity of dusty weather by applying microwave radars and lidar

Science of The Total Environment, 2023
Detection of the intensity of dusty weather is critical for weather forecasting. In this paper, the effective detection ranges of microwave radars and lidar in dusty weather of different intensities were theoretically calculated, which are validated by the microwave radar and lidar detection data in real dusty weather.

Assessing the utility of visible-to-shortwave infrared reflectance spectroscopy for analysis of soil weathering intensity and paleoclimate reconstruction

Palaeogeography, Palaeoclimatology, Palaeoecology, 2017
Visible-to-shortwave infrared reflectance (VSWIR) spectroscopy is a fast and efficient approach for estimation of soil properties. In order to test whether soil weathering intensity can be predicted using reflectance spectra in the VSWIR range (350–2500 ...

Reflectance spectroscopy applied to clay mineralogy and alteration intensity of a thick basaltic weathering sequence in Hainan Island, South China

, 2020
Visible/Near Infrared Reflectance spectroscopy (350–2500 nm) is an efficient and effective tool to identify and semi-quantify clay minerals, Fe3+ (oxyhydr)oxides, and their crystal-chemistry/structure.

Removal of nonprecipitation echoes in weather radar using multifractals and intensity

IEEE Transactions on Geoscience and Remote Sensing, 2002
In this paper, we present an algorithm for the automated removal of nonprecipitation related echoes such as atmospheric anomalous propagation (AP) in the lower elevations of meteorological-radar volume scans. The motivation or the development of this technique is the need for an objective quality control algorithm that minimizes human interaction.
