  1. HTB data collection Mesoscale Atmospheric Network Workshop University of Helsinki, 12 February 2007 Heikki Turtiainen

  2. Developments in observation network communications sensor 1 communications unit data logger sensor n conventional data collection system data transmission to database sensor bus sensor 1 two-way data connection to database / network management system - always on TCP/IP communications unit (with data buffer) GPRS, ADSL, WLAN, WiMax... sensor n

  3. Helsinki Testbed data collection Surface observations CO2 Ceilometers ADSL FMI APN Mobile observation platforms GSM/GPRS IP (VPN) ADSL LAN Soundings Wind Profiler GPS

  4. Data collection + interface to CDW Surface obs, soundings, WP FMML - XML schema TestbedMetMan SOA interface IP IP CDW http IP CL31 Existing FMI data streams

  5. Testbed data collection: application platforms • Surface observation stations • Aplicom 12 GSM engine with Java (J2Me) environment • Network control interface adapter for various observation equipment • TCP/IP based communications middleware for transporting data over GSM/GPRS network to / from MetMan and other network management systems • Same software (with some platform dependent libraries) can be run for example in MetMan 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 J2Me application

  6. Data collection: application platforms contd. • Vaisala MetMan • Vaisala Solutions product for observation data management • Microsoft Windows operating environment • Collecting the data from observation stations • Data conversion to FMML and html posting to central data warehouse

  7. HTB data flow - original architecture

  8. HTB data flow - current architecture (temporary)
