Aircraft Observation of a Two-Layer Cloud and the Analysis of Cold Cloud Seeding Effect

Frontiers in Environmental Science, 2022
A two-layer stratus cloud was developed under the weather of an upper-level trough and return flow in North China. King-air 350 meteorological aircraft was designated to acquire the microphysical characteristics of this cloud. Within the lower-level warm

Comparing diagnosed observation uncertainties with independent estimates: A case study using aircraft‐based observations and a convection‐permitting data assimilation system

Atmospheric Science Letters, 2021
Aircraft can report in situ observations of the ambient temperature by using aircraft meteorological data relay (AMDAR) or these can be derived using mode‐select enhanced tracking data (Mode‐S EHS).

Modeling method for refraction error compensation in ground object detection. [PDF]

PLoS ONE
The refraction error compensation model for ground object detection is established. Firstly, based on a 100-meter interval, the area between the aircraft and the ground objects is stratified, and the Hopfield model of the atmospheric refractive index is ...
