Background
• Trend forecasts to be performed from forecasting centrals
• Online presentation of all instrument measured meteorological parameters
• Video images covering the sky around the airport
• METAR to be made by airport employees
• TREND to be added at forecasting centrals
• Near true time presentation of measurements

Instrumentation
• Wind measurements– at least to sites along each runway
• Air temperature, humidity and air pressure– sensors connected to datalogger at the airport
• Ceilometers– giving cloud bases and vertical visibility
• Visibility– transmissometers or forward scatter
instrumentation, the forward scatter instruments includes PW algorithms.
• Video cameras– up to 6 cameras in use at a specific airport

System design
• Serial outputs connected to LAN– Terminalservers used
• Modems used for ceilometers and forward scatter instruments
• Wind directly connected to terminalserver
• Videocameras connected via videoserver
• Net connected LINUX server

Configuration
• Configuration tables stored in database
• Tools to create/change configuration are developed
• The user interface can be tailored to users need by configuration changes
• New sensors can be added by using existing parameter configuration tables

Conclusion and spin-offs
• Flexible and stable system, easy to change to fit other applications.
• The same technology are now used to collect data from automatic weather stations
• Data collection from the weather ship Mike
• On line access to a new meteorological station in the Antarctic
