The primary goal of this website is to make data freely available in an open manner. This page presents details the IEM's Application Programming Interface (API).
But first, perhaps there are better alternatives!
The following is a list of other web service providers. They all do a better job than this website does. Some of these are commercial and this listing should not be implied as an endorsement. Of course, you can just search google for Weather API :)
But you are here wondering about the IEM's API services? Presently, there are two portals with information about IEM APIs:
- Legacy ad-hoc/legancy (Geo)JSON services
These have been around for a while and while they work, they are generally somewhat brittle.
- IEM API v1 Documentation
Work is ongoing now to migrate the services found in #1 above into a more robust and self-documenting API system. This is the future and will see significant expansion during 2020.
In general, we do not try to break things but bugs happen. The plan is to auto-redirect any of the legacy services into the more modern API system. As always, please email us with any concerns you have. We are extremely responsive to email :)
- 24 April 2020: Update this page to reflect the new API services and migrate the backend to use it!
