Abstract: ‍ ‍Wind vector， temperature and pressure are very important aviation meteorological information， which is related to the flight safety of aircraft. The monitoring data from the aircraft can be updated more quickly and cover a wider area， which can be used on most of the aircraft and in the majority of regions. It is an economical and feasible method to retrieve meteorology based on aircraft monitoring data. In order to supplement and improve the existing aviation meteorological system， a meteorological parameter inversion method based on the fusion data of Automatic Dependent Surveillance-Broadcast （ADS-B） and Mode S Secondary Surveillance Radar （SSR） is proposed， which uses airspeed， ground speed and barometric altitude to invert meteorological parameters， and is applied to two scenarios of single route and regional inversion. The comparison with the existing meteorological system shows that both single route and regional inversion have high inversion accuracy， which can well complement the existing aviation weather acquisition network.
