Abstract: Disclosed is a method for obtaining meteorological data by a UAS, the UAS including at least one UAV, a control center and a wireless communication interface. The UAV is equipped with a meteorological data sensor and a flight controller. The method includes the control center sending flight instruction data to the UAV, and performing flight. The UAV collects raw meteorological data and flight data and transmits the collected raw meteorological data and the flight data in real time to the control center, the flight data being collected by any one of a position sensor, a motion sensor, an environment sensor and/or a combination thereof included in the flight controller. The control center calculates meteorological data based on the received raw meteorological data and the flight data and sends return instruction data. The at least one UAV returns to the UAS accordingly.
