Created for usage on [api.existenz.ch](https://api.existenz.ch) and indirectly on [Aare.guru](https://aare.guru). As of 2025 in productive use. SwissMetNet ----------- [](#swissmetnet) Starting from may 2025, [MeteoSwiss](https://www.meteoschweiz.admin.ch/) (Bundesamt für Meteorologie und Klimatologie/Federal Office of Meteorology and Climatology) publishes their [SwissMetNet](https://www.meteoswiss.admin.ch/home/measurement-and-forecasting-systems/land-based-stations/automatisches-messnetz.html) measurement data on the new [OGD Portal](https://data.geo.admin.ch/browser/index.html#/collections/ch.meteoschweiz.ogd-smn). See their [Open Data Documentation](https://opendatadocs.meteoswiss.ch) for further information. Measures air temperatures, rain rate/precipitation, wind, pressure, geopotentials, sunshine duration and more. Not every station measures every parameter. Note that most stations measure this 2 meters above ground, but some tower stations locate their sensors higher in the air. The parameters with suffix `_tow` are measured on tower stations. Periodicity: 10 minutes. **Licencing restrictions apply by MeteoSwiss.** [CC-BY](https://creativecommons.org/licenses/by/4.0/). You will have to credit any usage of the data with the string "Source: MeteoSwiss". See the official [Terms of Use](https://opendatadocs.meteoswiss.ch/general/terms-of-use) for details. ### Getting the data [](#getting-the-data) 1. Go to the STAC browser for the [Automatic weather stations](https://data.geo.admin.ch/browser/index.html#/collections/ch.meteoschweiz.ogd-smn). 2. Download the assets for station and parameter metadata CSV files. 3. Go to the desired station. 4. Download the assets for the measurement data as CSV files. There is a special file called `VQHA80.csv`only mentioned [in the documentation](https://opendatadocs.meteoswiss.ch/a-data-groundbased/a1-automatic-weather-stations?data-structure=one-file-with-all-stations). It contains last measured values for all stations for the main parameters. This file is updated every 10 minutes. ### Data format 2025 [](#data-format-2025) Starting from may 2025 the assets with historical data are published. They differ slightly again from the previous format: Different headers and a different time format: ``` station_abbr;reference_timestamp;tre200s0;tre005s0;tresurs0;xchills0;ure200s0;tde200s0;pva200s0;prestas0;pp0qnhs0;pp0qffs0;ppz850s0;ppz700s0;fkl010z1;fve010z0;fkl010z0;dkl010z0;wcc006s0;fu3010z0;fkl010z3;fu3010z1;fu3010z3;rre150z0;htoauts0;gre000z0;ods000z0;oli000z0;olo000z0;osr000z0;sre000z0 BER;01.02.2004 00:00;7.4;1.7;;;66.2;1.5;6.8;955.5;1022.3;1023.1;;;5.8;3;;258;;10.8;;20.9;;0;;6;;;;;0 BER;01.02.2004 00:10;7.6;1.8;;;65.7;1.6;6.9;955.5;1022.3;1023;;;7.9;3.6;;246;;13;;28.4;;0;;0;;;;;0 ... ``` ### Data format 2020 [](#data-format-2020) Starting from 2020-10-19 the data format of `VQHA80` changed slighty from the orginial CSV format: They are now valid CSV files, semicolon separated, with a new header line: ``` Station/Location;Date;tre200s0;rre150z0;sre000z0;gre000z0;ure200s0;tde200s0;dkl010z0;fu3010z0;fu3010z1;prestas0;pp0qffs0;pp0qnhs0;ppz850s0;ppz700s0;dv1towz0;fu3towz0;fu3towz1;ta1tows0;uretows0;tdetows0 TAE;202010191400;11.90;0.00;10.00;326.00;67.50;6.10;26.00;4.30;7.20;957.70;1021.00;1021.20;-;-;-;-;-;-;-;- COM;202010191400;11.70;0.00;0.00;100.00;68.30;6.10;114.00;1.80;4.30;955.90;1023.60;1023.80;-;-;-;-;-;-;-;- ... ``` ### Data format [](#data-format) MeteoSwiss data files `VQHA80` are semicolon separated CSVs with a custom header: ``` MeteoSchweiz / MeteoSuisse / MeteoSvizzera / MeteoSwiss stn;time;tre200s0;rre150z0;sre000z0;gre000z0;ure200s0;tde200s0;dkl010z0;fu3010z0;fu3010z1;prestas0;pp0qffs0;pp0qnhs0;ppz850s0;ppz700s0;dv1towz0;fu3towz0;fu3towz1;ta1tows0;uretows0;tdetows0 TAE;201911222230;2.4;0.0;0;1;97;1.9;93;5.0;10.8;939.0;1003.3;1001.5;-;-;-;-;-;-;-;- COM;201911222230;4.1;0.1;0;1;99;4.0;343;3.6;5.0;944.1;1012.9;1011.4;-;-;-;-;-;-;-;- ... ``` ### Legay data format [](#legay-data-format) Older data files like `VQHA69.csv` used the pipe symbol as separators: ``` MeteoSchweiz / MeteoSuisse / MeteoSvizzera / MeteoSwiss stn|time|tre200s0|sre000z0|rre150z0|dkl010z0|fu3010z0|pp0qnhs0|fu3010z1|ure200s0|prestas0|pp0qffs0 TAE|201803301120|9.1|1|0.0|87|4.7|1000.1|10.4|73|937.6|1000.2 COM|201803301120|7.3|0|0.2|185|16.9|1005.2|26.6|94|938.3|1005.8 ... ``` ### Metadata format [](#metadata-format) The legacy metadata files are free form textual files with space separated tables. Good luck parsing those. Encoding is ISO-8859-1. This library outputs UTF-8. Starting from 2021, the metadata is split up into two files: A text file (I.e. `VQHA80_en.txt`) containing the parameter metadata and a link to a CSV (I.e. `ch.meteoschweiz.messnetz-automatisch_en.csv`) containing the location metadata. Starting from 2025, all metadata is published as CSV files. (`ogd-smn_meta_stations.csv` and `ogd-smn_meta_parameters.csv`).
