NOAA NCEI Daily Weather Observations for a Station

ncei/get-station-data

Returns daily weather observations for one NOAA GHCN-Daily station from NOAA NCEI: highest and lowest temperature, precipitation, snowfall, snow depth and wind, in metric units, for a date range. Station records reach back to the 1800s at the oldest stations; up to 3660 days are returned per call. Find a station id with ncei/find-stations. Data from NOAA's National Centers for Environmental Information, GHCN-Daily, doi:10.7289/V5D21VHZ, modified by Eden Engine (fields renamed, values converted to numbers); not an official NOAA product.

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "ncei/get-station-data" })

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