Aiming at defects of poor flexibility and small coverage area of traditional vehicular meteorological station in complex terrain

a kind of emergency meteorological observation system based on wireless sensor networks（ WSNs） is presented. The system includes data acquisition layer and remote data transmission layer

a portable meteorological observation node based on WSNs is achieved in data acquisition layer and a vehicular gateway with GPRS and the Beidou satellite communications modules in remote data transmission layer. Test result shows that the system is easy to deploy in emergency meteorological observations can effectrively broaden coverage area

increase density and precision and assure stable data transmission.
