    • Open Weather DataRoope TervoFinnish Meteorological InstituteAaltoes InsightsOpen Data6.2.2013 6.2.2013 1
    • What? Why?Finnish Meteorological Institute isopening weather data it owns: • Real time observations • Forecast models • And more…Countless opportunities to buildnew apps and services with weatherdata. • Weather impacts each and everyone. • Many fields and activities are affected by weather • Pure weather apps or weather integrated to apps 6.2.2013 2
    • ContentData is opened in phases: • First sets available by summer 2013 • New sets will be added during 2013-2014Data sets can be categorized into three types: • Real time observation • Latest observations from the area, weather radars… • Observation time series • Long time series from some point(s) • Forecast models • Time series to a single point or binary encoded grid data 6.2.2013 3
    • Example of Data Sets - Real Time ObservationsData set Description Time Estimated Interval publish dateWeather Observations Temperature, Wind, 10 min Summer 2013 Humidity, Ground Temperature…Sun Radiation UV, Short and Long Term 1 min Summer 2013 Radiation…Marine Observations Waves, Sea Temperature, 1h Summer 2013 Sea Level…Weather Radars Precipitation Rate, 5 min Summer 2013 Precipitation Amount…Lightning Thunder Strikes in Finland 5 min Summer 2013Soundings Temperature, Humidity, 2 times a day 2014 Pressure, Wind from ground to 25 km height 6.2.2013 4

    • Open Data InterfaceFMI open data portal is designed tomeet INSPIRE requirements• Catalog (CSW) provides a high level catalog.• View Service (WMS) shows the data as an example.• Download Service (WFS 2.0) provides the data in GML (Geography Markup Language) encoded form. • For large data sets as weather forecast model WFS provides a GML envelope with a link to the binary encoded data. 6.2.2013 7
    • Open Data Interface• O&M (Observation & Measurement) standard is honored.• Data format is optimized for data exchange and interoperability.• Interoperability in INSPIRE means the possibility to combine spatial data and services from different sources across the European Community in a consistent way.• And there will be much data available in next few years, take a look: • http://www.paikkatietoikkuna.fi/w eb/fi/kansallinen-aineistoluettelo • http://inspire.jrc.ec.europa.eu 6.2.2013 8
    • Open Data InterfaceRegistration will be required for opendata portal.• The user will get an API Key.• Transactions will be limited based on the API Key. • Catalog (CSW) will be open • Download Service (WFS) have loose limits • View Service (WMS) have quite strict limits 6.2.2013 9
    • Open Data InterfaceSo.. WMS is just for browsing the data.• If you want provide maps in your applications, you have to download the data and create your own WMS.WFS transaction limits are designed sothat• You should be able to download almost as much data as you want into your server.• But applications with lots of end users can not rely directly on FMI WFS.Possibility to purchase unlimitedaccess to the data. 6.2.2013 10
    • LibrariesFMI is also going to publish an opensource library ’MetO Lib’ to help loadingand handling data.• First JavaScript• Next some scripting language, but what? • Python? • PHP?Some sample client implementationsare going to be published as well. 6.2.2013 11
    • WhenThe portal is published by summer2013.• Beta version opens in February.• Beta version will contain some data but its content and API may change before the release date.• Try it out! We are eager to get feedback as soon as possible. 6.2.2013 12
