Scale Factors of the Thermospheric Density: A Comparison of Satellite Laser Ranging and Accelerometer Solutions
; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2021-12-24)
A major problem in the precise orbit determination (POD) of satellites at altitudes below 1,000 km is the modeling of the aerodynamic drag which mainly depends on the thermospheric density and causes the largest non‐gravitational ... -
Sensitivity of Convection Permitting Simulations to Lateral Boundary Conditions in Idealized Experiments
; (Journal of Advances in Modeling Earth Systems, 2021-12-23)
Limited‐area convection‐permitting climate models (CPMs) with horizontal grid‐spacing less than 4 km and not relying on deep convection parameterisations (CPs) are being used more and more frequently. CPMs represent ... -
The Role of Moisture Conveyor Belts for Precipitation in the Atacama Desert
; ; ; (Geophysical Research Letters, 2021-12-22)
In the hyperarid Atacama Desert in northern Chile, rare precipitation events can leave long‐lasting geomorphological traces and have strong impacts on biota. While moisture conveyor belts (MCBs) and atmospheric rivers (ARs) ... -
Improving Atmospheric Angular Momentum Forecasts by Machine Learning
; ; ; (Earth and Space Science, 2021-12-20)
Earth angular momentum forecasts are naturally accompanied by forecast errors that typically grow with increasing forecast length. In contrast to this behavior, we have detected large quasi‐periodic deviations between ... -
Paleoclimate Evolution on Titan After Episodic Massive Methane Outgassing Simulated by a Global Climate Model
; (Journal of Geophysical Research: Planets, 2021-12-19)
Titan's paleoclimate after the onset of the putative last major methane outgassing event 700 Myr ago is simulated by a global climate model. If the atmosphere was methane‐depleted prior to outgassing, outgassed methane ... -
The Spectrum of Slip Behaviors of a Granular Fault Gouge Analogue Governed by Rate and State Friction
; ; (Geochemistry, Geophysics, Geosystems, 2021-12-15)
Currently, it is unknown how seismic and aseismic slip influences the recurrence and magnitude of earthquakes. Modern seismic hazard assessment is therefore based on statistics combined with numerical simulations of fault ... -
