Feature Extraction for Moving Targets Based on the Statistical Characteristics of Echo Amplitude with the L-Band Fully Polarimetric Radar

Remote Sensing, 2022
Non-imaging radar can achieve the detection and localization of moving targets, but it faces difficulties in the classification of targets. Aiming for the application of moving target classification by low/medium resolution non-imaging radar, this paper ...

Satellite Observations Show Negligible Impact of Mineral Dust on Cloud Droplet Number

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The susceptibility of cloud droplet number concentration Nd $\left({N}_{\mathrm{d}}\right)$ to aerosols (β) $(\beta )$ remains challenging to constrain in satellite observations. This difficulty arises from limitations in representing cloud condensation nuclei, which depend on aerosol size and composition.

Advancing Convective Precipitation Nowcasting via 3D Polarimetric Radar Data and Physics‐Constrained Deep Learning Model

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Accurate nowcasting of severe convective precipitation is critical for early warning yet still remains challenging. Although deep learning methods show promise, most models lack physical constraints, limiting their consistency with atmospheric processes.
