TITAN‐LSTM: A Weather Radar Nowcasting Tool
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Precipitation nowcasting is essential for a wide range of meteorological and hydrological applications, and weather radar plays a central role in this task. Extrapolation algorithms such as TITAN (Thunderstorm Identification, Tracking, Analysis and Nowcasting) provide efficient storm tracking but do not directly use rainfall rate fields, while

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Nanophotonics, Volume 15, Issue 14, 27 July 2026.A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

Polarimetric Differential-TomoSAR Imaging [PDF]
, 2010 Recently, in parallel to the maturation of the operative InSAR techniques based on phase-only data, much interest has grown in techniques based on the coherent combination of SAR images at the complex (amplitude and phase) data level, for the extraction ...
