Serving Open Data from mixed on-premise and cloud environment at the Finnish Meteorological Institute.

Finnish Meteorological Institute has a long history of open data. Partly as a result of the INSPIRE directive almost all important data was opened back in 2013. Because of this we have quite a long history of usage of the data and as well experience on technical solutions and user needs. The presentation will open up the current status and future development keeping in mind the upcoming WMO WIS2 development as well as the Open Data directive with its High Value Dataset proposal which will very likely feature meteorological datasets.

Data is provided via machine-readable interfaces as well as human usable web interfaces. We use on-premise storage and interfaces and in addition also offer cloud-based distribution such as the Amazon Public Dataset program. The current operational interfaces are based on WFS 2.0 and WMS. Most recently added datasets include weather and flood warnings in Common Alerting Protocol (CAP) format, black carbon measurements and radar data archive via Amazon S3 in GeoTIFF and HDF5 formats. There is development starting for providing data via even more developer-friendly interfaces such as the OGC Features API. Also new data is being added continuously based on our own and user needs.

An impact study has also been conducted for the year 2018 which reveals some findings on what data is used and how it impacts the users and their potential businesses. Also valuable information on the future needs of users was gathered and the most important findings of this study will be presented during the session.
