The low-latitude sodium layer: comparative data from lidar observations at Hainan, China and São Paulo, Brazil

Earth and Planetary Physics
Physical and chemical processes observed in the mesosphere and thermosphere above the Earth’s low latitudes are complex and highly interrelated to activity in the low-latitude ionosphere.

Artificial Intelligence-Based Precipitation Estimation Method Using Fengyun-4B Satellite Data

Remote Sensing
This paper proposes a novel precipitation estimation method based on FY-4B meteorological satellite data (FY-4B_AI). This method facilitates the spatiotemporal matching of 125 features derived from the multi-temporal and multi-channel data of the FY-4B ...

Estimating COSMIC ionospheric radio occultation foF2 error using the three-cornered hat method

Journal of Space Weather and Space Climate
GNSS ionospheric radio occultation (IRO) is an important technique for remote sensing of Earth’s ionosphere. Previous validation of GNSS IRO has often been based on comparisons with ground-based observations, such as ionosondes or in-situ observations ...

Revisiting the solar wind structures contributing crucially to the main phase of the major geomagnetic storms in May 1997

Terrestrial, Atmospheric and Oceanic Sciences
We re-examined the contributions of the sheath region and the magnetic cloud to the main phase of the major geomagnetic storm on May 15, 1997. Our analysis revealed that the maximum values of the southward component of the interplanetary magnetic field ...

Linking long-term switchback variability at 1 au to solar-surface mechanisms: A 27-year statistical study

Astronomy & Astrophysics
Context. Switchbacks–transient, large-angle deflections of the interplanetary magnetic field–pervade the solar wind, yet their origin remains disputed. Current ex situ theories, notably coronal jets and interchange reconnection, are typically tested on ...
