Drought Characteristics Derived Based on the Standardized Streamflow Index: A Large Sample Comparison for Parametric and Nonparametric Methods
(
- Water Resources Research
, 2020)
The streamflow drought hazard can be characterized in a variety of ways, including using different indices. Traditionally, percentile-based indices, such as Q95 (the flow exceeded 95% of time), have been used by the ...
The Relative Importance of Phytoplankton Light Absorption and Ecosystem Complexity in an Earth System Model
(
- Journal of Advances in Modeling Earth Systems
, 2021-05-17)
We investigate the relative importance of ecosystem complexity and phytoplankton light absorption for climate studies. While the complexity of Earth System models (ESMs) with respect to marine biota has increased over the ...
Fluctuations of the Atlantic North Equatorial Undercurrent and Associated Changes in Oxygen Transports
(
- Geophysical Research Letters
, 2020)
Abstract
Although the core velocity of the Atlantic North Equatorial Undercurrent (NEUC) is low (0.1−0.3 m s−1), it has been suggested to act as an important oxygen supply route towards the oxygen minimum zone in the ...
Origin of Weakened Interannual Sea Surface Temperature Variability in the Southeastern Tropical Atlantic Ocean
(
- Geophysical Research Letters
, 2020)
Observations and reanalysis products are used to investigate the substantial weakening in the southeastern tropical Atlantic sea surface temperature (SST) variability since 2000. Relative to 1982–1999, the March-April-May ...
Interleaving of oxygenized intrusions into the Baltic Sea redoxcline
(
- Limnology and Oceanography
, 2019)
Semi-enclosed marginal seas like the Baltic Sea are often characterized by permanently anoxic deep layers, and may therefore serve as important model systems to study the causes and consequences of the predicted global ...
Quantifying Uncertainties in Snow Depth Mapping From Structure From Motion Photogrammetry in an Alpine Area
(
- Water Resources Research
, 2019)
Mapping snow conditions in alpine areas is crucial for monitoring local hydrology to support water resource management decisions. Recently, the use of structure-from-motion multiview stereo 3-D reconstruction (or SFM ...
Hyper-Resolution Continental-Scale 3-D Aquifer Parameterization for Groundwater Modeling
(
- Water Resources Research
, 2020)
Groundwater is the world's most important freshwater resource. Despite this importance, groundwater flow and interactions between groundwater and other parts of the hydrological cycle are often neglected or simplified in ...
Global Assimilation of Ocean-Color Data of Phytoplankton Functional Types: Impact of Different Data Sets
(
- Journal of Geophysical Research: Oceans
, 2020)
Phytoplankton functional-type (PFT) data are assimilated into the global coupled ocean-ecosystem model MITgcm-REcoM2 for two years using a local ensemble Kalman filter. The ecosystem model has two PFTs: small phytoplankton ...
Inferring Air-Sea Carbon Dioxide Transfer Velocities From Sea Surface Scatterometer Measurements
(
- Journal of Geophysical Research: Oceans
, 2019)
C-band microwave sea surface radar backscatter observations from the FINO-2 tower in the western Baltic are analyzed with respect to their relevance for air-sea CO2 transfer velocity parameterizations. The scatterometer ...
Identification of groundwater mean transit times of precipitation and riverbank infiltration by two-component lumped parameter models
(
- Hydrological Processes
, 2019)
Groundwater transit time is an essential hydrologic metric for groundwater resources management. However, especially in tropical environments, studies on the transit time distribution (TTD) of groundwater infiltration and ...
