Intercomparison of Machine Learning Models to Determine the Planetary Boundary Layer Height Over Central Amazonia

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.
Abstract The planetary boundary layer height (zi) is a key parameter in meteorology and climatology, influencing weather prediction, cloud formation, and the vertical transport of scalars and energy near Earth's surface. This study compares multiple machine learning (ML) models that predict zi from surface measurements at two sites in Central Amazonia ...

First Observation of Ionospheric Plasma Bubble Signatures by Ca+ Lidar at Low Latitude

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Ionospheric plasma bubbles refer to density depletion structures in the ionosphere, which are usually seen in the electron density profiles observed by radar, and have never been observed in the density profiles of metallic ions. In this letter, we report the first observation of plasma bubble signatures captured by lidar, manifested as ...
