• Fixed internal server error when requesting data that is outside of stations valid date range, see #27.




We released a set of four new datasets, that supersede the klima-v1 datasets:

  • klima-v1-10min -> klima-v2-10min

  • klima-v1-1h -> klima-v2-1h

  • klima-v1-1d -> klima-v2-1d

  • klima-v1-1m -> klima-v2-1m


We advise you to switch your data queries to the new datasets in time. We will stop updating klima-v1 in the future.

New features

The new datasets bring a few improvements over the old klima-v1 datasets:

  • Faster updates. We now process each station individually and data is available, as soon as it is checked, instead of releasing in batches once per day.

  • More stations. Almost 100 stations (current and historic) have been added.

  • Faster requests. We improved data storage and retrieval. As a result klima-v2 should serve data faster than klima-v1 endpoints.

Backwards incompatible changes

  • Parameter names have changed. As part of a standardization process of parameter names among multiple datasets, parameter names were adjusted. You can find a mapping of the old parameter names to the new ones below:

  • Do not treat end_time as a reliable source for the last update time. In klima-v1 data was only updated once a day and the delayed ingestion, made end_time a quite reliable indicator for available data. Since we now update datasets continuously and process each station individually, there can be quite some difference between end_time and the station(s) you are interested in.


In accordance with the changes above, we also added more stations to the tawes-v1-10min dataset.


In some cases, there may be stations that are only available via tawes-v1-10min and not in klima-v2-10min. This can be an indicator, that these stations are very new and/or are temporary weather stations. Please note that temporary stations could be removed from the dataset without announcement!

Docs changes

  • Added explanation for the availability of historic forecasts

  • Added explanation on how to pass arrays to our API


  • Released two new forecast datasets:

    • chem-v1-1h-4km: Chemical weather prediction for Central Europe

    • chem-v1-1h-12km: Chemical weather prediction for Europe


  • Add BBOX format to description for grid queries #19

  • Fix mistyped projection EPSG:4325 to EPSG:4326.

  • Remove verified information from resource list, see #20.


  • Released an initial version of forecast endpoints

  • Forecasts: Added nowcasting dataset nowcast-v1-15min-1km.

  • Forecasts: Added numerical weather prediction dataset nwp-v1-1h-2500m.


Forecasts are available in prerelease stability. This feature is still under active development and subject to non-backwards compatible changes. Make sure you follow updates on the changelog and give us feedback on the endpoints on


Redirecting requests to

Requests to are now fowarded to with a HTTP 301 redirect. Make sure to update your code, to point to the new domain. Check this changelog or the Github Repository for updates regarding end-of-life of this redirect.


Use the URL for all API calls in new and existing projects.


  • Fixing timeout error when requesting large geojson datasets. #12


Release of

The API at is now live. This means:

We therefore strongly recommend to use the new URL for new applications and update existing ones. Your requests should not require any further changes since the endpoints are otherwise the same.

Updated dataset API documentation

The user documentation has been overhauled. The source code for the documentation is available at


  • Features

    • Adding snowgrid_cl-v2-1d-1km dataset

    • Adding spartacus-v2-1d-1km dataset

    • Adding spartacus-v2-1m-1km dataset

    • Adding spartacus-v2-1q-1km dataset

    • Adding spartacus-v2-1y-1km dataset

    • Adding winfore-v2-1d-1km dataset


  • Breaking

    • Removed lat and lon parameters in favor of lat_lon.

    • All timestamps returned from the API are changed from second to minute resolution, i.e. YYYY-MM-DDThh:mm+hh:mm. This may break parsers that rely on second resolution.

  • Features

    • Adding histalp-v1-1y endpoint.

  • Enhancements

    • Introducing lat_lon parameter for type timeseries.

    • Multiple coordinate pairs can be requested from timeseries data using the lat_lon parameters.

    • Introducing bboxOuter metadata for grid type data. bboxOuter defines the bbox parameter values limits.

  • Fixes

    • Fixing error when requesting data from more than one station with a station having no data for the requested time.

    • Fixing missing time steps when requesting data from more than one station all not having any data for this time period.

    • Updated outdated station metadata.

    • Fixed no timezone in CSV files.


  • API first release.
