Abstract: This study explored the feasibility of stratospheric airship platforms for continuously meteorological observations. The stratospheric airship platform, carrying the dropsonde, temperature sensor and pressure sensor, was designed to drop radiosonde from 18 km high of the stratosphere at its long standing stop. Following conclusions can be drawn from the test and analysis:1) The dropsonde-based airship platform is technically sound by providing real and effective observation data. Therefore, it is a stable and reliable means of observation; 2) Near space airship has the capability of continuous observation in the stratosphere, which is of great significance to the corresponding meteorological research in the stratosphere; 3) Observation locations need to be optimized if the airship platforms are used to observe stratospheric temperature because of large influence of fluid on temperature distribution.
