The Vertical Distribution of Ice-Nucleating Particles over the North China Plain: A Case of Cold Front Passage

Remote Sensing, 2023
Ice-nucleating particles (INPs) are crucial for cloud freezing processes in the atmosphere. Given the limited knowledge about the vertical distribution of INPs and its relation to aerosols in China, we present two aircraft observations of INPs over the ...

An SFDI Observer–Based Scheme for a General Aviation Aircraft [PDF]

International Journal of Applied Mathematics and Computer Science, 2013
Abstract The problem of detecting and isolating sensor faults (sensor fault detection and isolation-SFDI) on a general aviation aircraft, in the presence of external disturbances, is considered. The proposed approach consists of an extended Kalman observer applied to an augmented aircraft plant, where some integrators are added to the ...

Aircraft observations of a lightning channel in STEPS [PDF]

Geophysical Research Letters, 2003
We analyze a portion of an intracloud lightning channel that was captured on video by an instrumented aircraft and mapped three‐dimensionally by a ground‐based lightning mapping array (LMA). By comparing the electric fields measured on the aircraft with a model which simulates the electrostatic field present after charge was effectively deposited by ...
