Data Usage/Visualisation • Visualisation/configuration/maintenance/report-entry within Met. Net using Almos client systems. Maintenance staff and observers/forecasters. • 10 -minute data of entire Met. Net provided to internal and external users. • Visualised by KNMI applications in time series and geographically incl. alarms and presented on intranet. • Local presentation of 12 -second airport data for ATC, Fire brigade, SAR. . . 6

Met. Net Key Numbers • Airport system Schiphol 60 SIAMs; 66 sub-stations (physically 23 x. ZM, pseudo, other airports) 12 ‘Runways’; 2 take-off + 2 landing, Reg. QNH & TL runway dep. sensors; backup sensors; cross/tail winds etc. 12 sec. updates (1300 variables out of 2100) • Central system De Bilt 21 AWSs; 7+9 airports; 27 DNZ; 20 ZEGE; 26 MSW total of 350 (sub)stations 2500 1 -min variables; 4900 10 -min; 9600 total; 7 days • Configuration changes (distributed centrally) > 100. 12
Availability 13
Met. Net Evaluation and Future l l l Project finished on time with required functionality and stable. Cooperation Almos and KNMI resulted is a good product. Maintenance had difficult and busy start. Met. Net very dynamic: 5 th RWY Schiphol, renumbering RWYs, many sensor and some station changes, 9 airbases). New functionality: FLITS, Auto METAR, Auto Trend, security issues, maintenance tools, OS upgrade. Upcoming changes: ISDN GRPS, AVW-RNLAF, FTP-XML format platforms, BUFR, bugs/wishes. . . Tools for 10 -minute data visualisation and experience in usage. 14
