The Mini Induced Magnetospheres at Mars
; ; ; ; ; (Geophysical Research Letters, 2023-02-08)
We report on observations made by the Mars Atmosphere and Volatile EvolutioN spacecraft at Mars, in the region of the ion plume. We observe that in some cases, when the number density of oxygen ions is comparable to the ... -
The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures
; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2023-02-07)
Based on inferences from proxy records the Miocene (23.03–5.33 Ma) was a time of amplified polar warmth compared to today. However, it remains a challenge to simulate a warm Miocene climate and pronounced polar warmth at ... -
Observations of Gravity Wave Refraction and Its Causes and Consequences
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2023-02-06)
Horizontal gravity wave (GW) refraction was observed around the Andes and Drake Passage during the SouthTRAC campaign. GWs interact with the background wind through refraction and dissipation. This interaction helps to ... -
Missing Rainfall Extremes in Commercial Microwave Link Data Due To Complete Loss of Signal
; ; (Earth and Space Science, 2023-02-06)
An important aspect of rainfall estimation is to accurately capture extreme events. Commercial microwave links (CMLs) can complement weather radar and rain gauge data by estimating path‐averaged rainfall intensities near ... -
Timing and Origin of Compressional Tectonism in Mare Tranquillitatis
; ; ; ; ; (Journal of Geophysical Research: Planets, 2023-02-05)
The lithosphere of the Moon has been deformed by tectonic processes for at least 4 billion years, resulting in a variety of tectonic surface features. Extensional large lunar graben formed during an early phase of net ... -
Cenozoic Exhumation and Deformation of the Intermontane Pastos Chicos Basin in the Southern Central Andes: Implications for the Tectonic Evolution of the Andean Plateau (Puna) and the Eastern Cordillera Between 23° and 24°S, NW Argentina
; ; ; ; ; ; ; (Tectonics, 2023-02-03)
The Andean Plateau of north‐western Argentina (Puna) at a mean elevation of ca. 4.2 km constitutes the southern continuation of the Altiplano; it is a compressional basin‐and‐range province comprising fault‐bounded, ... -
Characteristics of the Matuyama‐Brunhes Magnetic Field Reversal Based on a Global Data Compilation
; ; (Journal of Geophysical Research: Solid Earth, 2023-02-01)
Magnetic field reversals are irregular events in Earth's history when the geomagnetic field changes its polarity. Reversals are recorded by spot and continuous remanent magnetization data collected from lava flows and ... -
Hard X‐ray full‐field nanoimaging using a direct photon‐counting detector
(Journal of Synchrotron Radiation, 2023-02-01)Full‐field X‐ray nanoimaging is a widely used tool in a broad range of scientific areas. In particular, for low‐absorbing biological or medical samples, phase contrast methods have to be considered. Three well established ... -
Simulating the soil phosphorus dynamics of four long‐term field experiments with a novel phosphorus model
; ; ; ; ; (Soil Use and Management, 2023-02-01)
Phosphorus is a nonrenewable resource, which is required for crop growth and to maintain high yields. The soil P cycle is very complex, and new model approaches can lead to a better understanding of those processes and ... -
Climate Impact Comparison of Electric and Gas‐Powered End‐User Appliances
; ; ; ; ; ; ; ; ; (Earth's Future, 2023-02-01)
Natural gas is considered a bridging technology in the energy transition because it produces fewer carbon emissions than coal, for example. However, when leaks exist, methane is released into the atmosphere, leading to a ... -
Sea Level Changes Affect Seismicity Rates in a Hydrothermal System Near Istanbul
; ; ; (Geophysical Research Letters, 2023-01-31)
Small stress changes such as those from sea level fluctuations can be large enough to trigger earthquakes. If small and large earthquakes initiate similarly, high‐resolution catalogs with low detection thresholds are best ... -
Controls on Flood Trends Across the United States
; ; ; (Water Resources Research, 2023-01-30)
Trends in flood magnitudes vary across the conterminous USA (CONUS). There have been attempts to identify what controls these regionally varying trends, but these attempts were limited to certain—for example, climatic—variables ... -
The Role of Mineral Dust Aerosol Particles in Aviation Soot‐Cirrus Interactions
