Roadmap
This is the current roadmap of our Open Data service, which shows what we are working on and when.
- It is iterated on at least a quarterly basis.
- It allows us to plan for change. It captures intent, not solutions. The further into the future a thing will take place, the more uncertain it is.
- Things can be added to or dropped from the roadmap. In the latter case, we document this below under ‘Items removed from the roadmap’, including the date and reason.
suggerimento
The roadmap is based on the Vision and strategy of MeteoSwiss' Open Data provision. In a nutshell:
- MeteoSwiss is implementing Open Data access in two stages, first through bulk download, then through APIs.
- Where implemented, both access modes remain operational.

July until September (Q3-2026)
Bulk download
Additional variables for the 'ICON-CH1/2-EPS' and 'KENDA-CH1' datasets/collections are made available by end of July
More about these additions.
The provision of real-time 'Ground-based measurements' and 'Radar data' will be improved by end of August.
The aim is to make the respective Open Data available, where possible, within the measurement interval.
'Reflectivity-based' and 'Convection radar products' are being prepared to be available by end of September
More info about these open data products will be coming soon.
'Radio soundings' are being prepared to be available by end of September
