Using on air UAT/ADS-B signal to simulate 3D aviation weather information

Abstract

The existing unusual weather alert system utilizes information provided by ground meteorological observation stations and simulates unusual weather conditions using a specific computational fluid dynamics model. However, the ground meteorological observation stations convey only 2D weather information near the ground, and it is very difficult to accurately simulate 3D low-level weather conditions using only 2D ground weather information. The purpose of the paper is thus to analyzing the possibility of simulating a 3D fluid flow field describing weather conditions using both meteorological observation data from ADS-B/UAT onboard aircrafts and ground meteorological observation stations. All the meteorological information collected for the paper is calculated to conduct 3D fluid flow field by the CALMET/CALPUFF Modeling system.
