This webmap was made during a 2-week long final project at a WBS qualification in webmapping
This project aims to show some of the abilities webmapping has to offer for climate data. Large datasets made easy accessible, userfriendly to explore and comparable to each other and observational data.
As a beginner in HTML, CSS, Javascript and Leaflet and with a limited time to do this project, it is not a full fledged climate information system!
Also NO serverside software like Geoserver or PostgreSQL is used, in order for the webmap to be independent without to have to pay for extra servers when put online by me.
Therefore, only a limited amount of climate data and only one observational station is used to show the potential. More data could be easily added with more time and a dedicated server.

COSMO-CLM data was produced by Lukas Schefczyk (me) in the Projects Global Change and TriCCS at the University Trier with the CCLM Model at the DKRZ. Data sets for Germany are provided by the German Weather Service via Geoserver (maps.dwd.de) and the Weather data is provided by
