Identification of Supercooled Cloud Water by FY-4A Satellite and Validation by CALIPSO and Airborne Detection

, 2022
Cold clouds are the main operation target of artificial precipitation enhancement, and its key is to find a supercooled cloud water area where the catalyst can be seeded to promote the formation of precipitation particles and increase precipitation to ...

Coevolution of phyllosilicate, carbon, sulfide, and apatite in Ryugu's parent body

Meteoritics &Planetary Science, Volume 59, Issue 8, Page 2073-2096, August 2024.
Abstract We analyzed an asteroid Ryugu sample returned to Earth by JAXA's Hayabusa2 mission using nanoIR, SEM, and TEM microscopy. We identified multiple distinct carbon reservoirs within the phyllosilicate matrix and demonstrate infrared spectral affinities for some of the carbon to insoluble organic matter (IOM).

Surface‐Guided Crystallization of Xanthine Derivatives for Optical Metamaterial Applications

Advanced Materials, Volume 36, Issue 8, February 22, 2024.
Millimeter sized extremely birefringent thin crystalline sheets formed from the small organic molecules theophylline and etophylline with controlled orientation are grown from solution via epitaxy with a quartz substrate. The films are then used to fabricate flat polarization‐dependent optical metamaterials.

Corrected event dataset of FY-4A LMI, 2019–2023

Abstract. The Lightning Mapping Imager (LMI) aboard the Fengyun-4A (FY-4A) satellite, once one of the only two geostationary lightning detection payloads operating in space, has accumulated a substantial volume of observational data. Extensive efforts have been made to correct lightning geolocation deviations, including payload misalignment correction,

A factorial spatial–temporal null-model framework for satellite–ground lightning fusion across Chinese marginal seas

International Journal of Applied Earth Observations and Geoinformation
Earth observation increasingly combines satellite and ground systems that record different manifestations of the same phenomenon. Spatial clustering and temporal persistence inflate apparent agreement, creating uncertainty over where joint products are ...
