Testbed data collection: application platforms Surface observation stations • Aplicom 12 GSM engine with Java (J 2 Me) environment • Network control interface adapter for various observation equipment • TCP/IP based communications middleware for transporting data over GSM/GPRS network to / from Met. Man and other network management systems • Same software (with some platform dependent libraries) can be run for example in Met. Man PC to provide similar interface for directly connected devices, ex. ceilometers with DXE 421 com server. Soundings, Wind Profiler • Microsoft Windows based measurement and data processing applications with native IP connectivity • Utilize the same communications middleware than J 2 Me application ©Vaisala | date | Ref. code | Page 5
