(Submission #112)


SmartMet Server is a data and product server for MetOcean Data used by Finnish Meteorological Institute (FMI). It provides high capacity and availability services for M2M and user interfaces. SmartMet Server has been optimized for on-demand queries and fast response.

Several output formats and interfaces as WMS, WFS 2.0, JSON, ASCII, HTML etc. are provided. WMS and WFS 2.0 services are INSPIRE compliant and have been basis of FMI INSPIRE data portal since 2013.

The server has been operative since 2008. SmartMet Server was originally developed for FMI client services, and since 2013 it’s been basis of FMI Open Data Portal. At the moment operative client server provides over 30 million requests per day, about 200 requests per second as a baseline with peaks over 650 requests per second. The operative server contains approximately 2 TB of data with update interval varying from 1 minute to 6 hours. End user availability has been over 99,95 %. Average response times are about 70 ms per request.

SmartMet server is going to be published as open source in 2016 under Common Creatives 4 (CC4) license.

So far, no scalability limits have been found. Still, increasing amount of requests keeps us working for better availability and to improve performance. The future plans contains amongst other things local copy of location database to achieve better scalability. WCS interface is also on the roadmap.
