SMHI Weather Station Observations: Latest Hour or Latest Day

smhi/get-observations

Measured values from one Swedish weather station for one SMHI parameter (air temperature, wind, pressure, precipitation, humidity and others; parameter ids from the parameter list tool): the newest hour (one reading) or the newest day (up to 24 hourly readings for hourly parameters). Each reading has a UTC timestamp in milliseconds, a value as a string and a quality code. Station ids come from the station list tool. A station that does not measure the parameter, or an unknown id, is refused by the service. SMHI data, served by Eden Engine; not an official SMHI product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "smhi/get-observations" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "smhi/get-observations" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "smhi/get-observations", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "smhi/get-observations", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
