Air‐Sea Interactions and Water Mass Transformation During a Katabatic Storm in the Irminger Sea
(
- Journal of Geophysical Research: Oceans
, 2022-04-28)
We use a global 5‐km resolution model to analyze the air‐sea interactions during a katabatic storm in the Irminger Sea originating from the Ammassalik valleys. Katabatic storms have not yet been resolved in global climate ...
Spatio‐Temporal Level Variations of the Martian Seasonal South Polar Cap From Co‐Registration of MOLA Profiles
(
- Journal of Geophysical Research: Planets
, 2022-07-18)
The seasonal deposition and sublimation of CO2 represents a major element in the Martian volatile cycle. Here, co‐registration strategies are applied to Mars Orbiter Laser Altimeter profiles to obtain spatio‐temporal ...
Sound Velocity Measurements of B2‐Fe‐Ni‐Si Alloy Under High Pressure by Inelastic X‐Ray Scattering: Implications for the Composition of Earth's Core
(
- Geophysical Research Letters
, 2022-08-04)
Elastic properties of B2‐Fe0.67Ni0.06Si0.27 (15 wt.% Si) alloy have been investigated by combined high‐resolution inelastic X‐ray scattering and powder X‐ray diffraction in diamond anvil cells up to 100 GPa at room ...
Algorithmic Differentiation for Sensitivity Analysis in Cloud Microphysics
(
- Journal of Advances in Modeling Earth Systems
, 2022-07-12)
The role of clouds for radiative transfer, precipitation formation, and their interaction with atmospheric dynamics depends strongly on cloud microphysics. The parameterization of cloud microphysical processes in weather ...
Basin‐scale estimates of greenhouse gas emissions from the Mara River, Kenya: Importance of discharge, stream size, and land use/land cover
(
- Limnology and Oceanography
, 2022-06-23)
Greenhouse gas fluxes (CO2, CH4, and N2O) from African streams and rivers are under‐represented in global datasets, resulting in uncertainties in their contributions to regional and global budgets. We conducted year‐long ...
Contrasting State‐Dependent Effects of Natural Forcing on Global and Local Climate Variability
(
- Geophysical Research Letters
, 2022-05-17)
Natural forcing from solar and volcanic activity contributes significantly to climate variability. The post‐eruption cooling of strong volcanic eruptions was hypothesized to have led to millennial‐scale variability during ...
Mapping the Brightness of Ganymede's Ultraviolet Aurora Using Hubble Space Telescope Observations
(
- Journal of Geophysical Research: Planets
, 2022-06-15)
We analyze Hubble Space Telescope observations of Ganymede made with the Space Telescope Imaging Spectrograph between 1998 and 2017 to generate a brightness map of Ganymede's oxygen emission at 1,356 Å. Our Mercator projected ...
Tropical Continents Rainier Than Expected From Geometrical Constraints
(
- AGU Advances
, 2022-07-06)
Abundant rainfall over tropical land masses sustains rich ecosystems, a crucial source of biodiversity and sink of carbon. Here, we use two characteristics of the observed tropical precipitation distribution, its distinctive ...
Improving the Vertical Modeling of Tropospheric Delay
(
- Geophysical Research Letters
, 2022-03-08)
Accurate tropospheric delays from Numerical Weather Models (NWM) are an important input to space geodetic techniques, especially for precise real‐time Global Navigation Satellite Systems, which are indispensable to earthquake ...
Ensemble Kalman filter based data assimilation for tropical waves in the MJO skeleton model
(
- Quarterly Journal of the Royal Meteorological Society
, 2022-02-21)
The Madden–Julian oscillation (MJO) is the dominant component of tropical intraseasonal variability, with wide‐reaching impacts even on extratropical weather and climate patterns. However, predicting the MJO is challenging. ...
