Using the Fourier Neural Operator and Real‐Time GOES‐R Satellite Data for Precipitation Retrievals in the Southern Great Plains

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract In the U. S. Southern Great Plains (SGP) region, severe weather occurs regularly during the warm season (e.g., June–August), causing extensive property damage and loss of life. Despite advancements in observations and numerical models, estimating precipitation associated with these severe weather events remains challenging, thereby ...

Space‐Time Causal Discovery in Earth System Science: A Local Stencil Learning Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Causal discovery tools enable scientists to infer meaningful relationships from observational data, spurring advances in fields as diverse as biology, economics, and climate science. Despite these successes, the application of causal discovery to space‐time systems remains immensely challenging due to the high‐dimensional nature of the data ...

A preliminary experiment of determining the geopotential difference using two hydrogen atomic clocks and TWSTFT technique

Geodesy and Geodynamics, 2020
General relativity theory (GRT) concludes that a precise clock ticks at different running rates if it is under the influence of different geopotentials.

Characteristics and Predictability of Extreme Precipitation Related to Atmospheric Rivers, Mesoscale Convective Systems, and Tropical Cyclones in the U.S. Southeast

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract The Southeastern United States (SEUS) region has lower extreme quantitative precipitation forecast (QPF) skill compared to the northeastern or western United States. Previous studies have reported that the extreme precipitation events (EPEs) with high integrated vapor transport (IVT) have higher QPF skill than those with low IVT in the SEUS ...

Anomalous Vertical Structure of Tropospheric Ozone Due To Stratospheric Intrusions and Convective Transport

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Vertical transport carries airmasses from different sources of tropospheric O3 including photochemical production and stratospheric intrusions, and is crucial for vertical O3 variability. Based on temporally dense ozonesondes over northern China, this study reports an anomalous vertical O3 distribution characterized by a “bottom‐heavy ...

The impact of the new CHAMP and GRACE Earth gravity models on the measurement of the general relativistic Lense--Thirring effect with the LAGEOS and LAGEOS II satellites

, 2003
Among the effects predicted by the General Theory of Relativity for the orbital motion of a test particle, the post-Newtonian gravitomagnetic Lense-Thirring effect is very interesting and, up to now, there is not yet an undisputable experimental direct ...

From Sea to Summit: Investigating the Explicit Role of SST Increase for Regional and High‐Altitude Climates in New Zealand

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract The oceans around New Zealand are regional warming hotspots where sea surface temperature (SST) is rising much faster than the global average. This study uses a sensitivity experiment with a regional atmospheric model to investigate how ocean warming over the past decade (2010–2020) has influenced New Zealand's climate at different spatial ...
