Magnetic Surveys With Unmanned Aerial Systems: Software for Assessing and Comparing the Accuracy of Different Sensor Systems, Suspension Designs and Compensation Methods
(
- Geochemistry, Geophysics, Geosystems
, 2021-07-13)
A typical problem for magnetic surveys with small Unmanned Aerial Systems (sUAS) is the heading error caused by undesired magnetic signals that originate from the aircraft. This can be addressed by suspending the magnetometers ...
Predicting Geothermal Heat Flow in Antarctica With a Machine Learning Approach
(
- Journal of Geophysical Research: Solid Earth
, 2021-06-10)
We present a machine learning approach to statistically derive geothermal heat flow (GHF) for Antarctica. The adopted approach estimates GHF from multiple geophysical and geological data sets, assuming that GHF is substantially ...
Correlation Based Time Evolution of the Archeomagnetic Field
(
- Journal of Geophysical Research: Solid Earth
, 2021-07-16)
In a previous study, a new snapshot modeling concept for the archeomagnetic field was introduced (Mauerberger et al., 2020, https://doi.org/10.1093/gji/ggaa336). By assuming a Gaussian process for the geomagnetic potential, ...
Earth’s Albedo and Its Symmetry
(
- AGU Advances
, 2021-08-11)
The properties of Earth's albedo and its symmetries are analyzed using twenty years of space‐based Energy Balanced And Filled product of Clouds and the Earth's Radiant Energy System measurements. Despite surface asymmetries, ...
Piecewise Evolutionary Spectra: A Practical Approach to Understanding Projected Changes in Spectral Relationships Between Circulation Modes and Regional Climate Under Global Warming
(
- Geophysical Research Letters
, 2021-07-16)
Regional climate variability is strongly related to large‐scale circulation modes. However, little is known about changes in their spectral characteristics under climate change. Here, we introduce piecewise evolutionary ...
Upper‐level trajectories in the prototype problem for tropical cyclone intensification
(
- Quarterly Journal of the Royal Meteorological Society
, 2021-07-12)
Data from an idealized three‐dimensional numerical simulation of tropical cyclone intensification are used to calculate Lagrangian air parcel trajectories emanating from the inflow layer that develops beneath the ...
Polar Stratospheric Clouds: Satellite Observations, Processes, and Role in Ozone Depletion
(
- Reviews of Geophysics
, 2021-06-10)
Polar stratospheric clouds (PSCs) play important roles in stratospheric ozone depletion during winter and spring at high latitudes (e.g., the Antarctic ozone hole). PSC particles provide sites for heterogeneous reactions ...
Deep Emulators for Differentiation, Forecasting, and Parametrization in Earth Science Simulators
(
- Journal of Advances in Modeling Earth Systems
, 2021-06-28)
To understand and predict large, complex, and chaotic systems, Earth scientists build simulators from physical laws. Simulators generalize better to new scenarios, require fewer tunable parameters, and are more interpretable ...

Diagnosis of Model Errors With a Sliding Time‐Window Bayesian Analysis
(
- Water Resources Research
, 2022-02-17)
Deterministic hydrological models with uncertain, but inferred‐to‐be‐time‐invariant parameters typically show time‐dependent model errors. Such errors can occur if a hydrological process is active in certain time periods ...
