Get Aggregated Observations — WindBorne observations are high-frequency, at once every ten seconds, but as our balloons are comparatively slow-moving (relative to the distances at which weather changes), this may be excessive for some applications. Indeed, previous data assimilation experiments have suggested that reducing the resolution of the dataset helps with impact.
Documentation: https://api.windbornesystems.com/observations/version_1/observations/super-observations/
Default endpoint: https://api.windbornesystems.com
Get All Soundings — Discover which atmospheric soundings have been collected by WindBorne's global balloon constellation. This endpoint allows you to search for soundings by time, location, altitude, and mission, making it easy to discover which soundings are available before fetching the full sounding data.
Documentation: https://api.windbornesystems.com/observations/version_1/soundings/all-soundings/
Default endpoint: https://api.windbornesystems.com/observations/v1/soundings
Get Archived Initialization Times — Returns a list of archived initialization times (model run start times) for the selected weather model. Results are paginated. Use page and page_size to control pagination, and order to sort by newest or oldest first. For archived runs, only full gridded forecast data is available.
Documentation: https://api.windbornesystems.com/forecasts/version_1/forecast-availability/archived-initialization-times/
Default endpoint: https://api.windbornesystems.com/forecasts/v1/wm-6/initialization_times/arch
Get Available Stations — Returns the list of METAR weather stations for which MetaMesh generates station forecasts. Use the station IDs from this endpoint with the Point Forecast endpoint.
Documentation: https://api.windbornesystems.com/forecasts/version_1/forecast-availability/available-stations/
Default endpoint: https://api.windbornesystems.com/forecasts/v1/point_forecast/stations
Get Calculation Times — Some forecast outputs are calculated after the underlying forecast data becomes available. This endpoint lets you check when degree day (HDD/CDD) and tropical cyclone calculations are available for each model initialization time, as well as which calculations are still in progress or incomplete.
Documentation: https://api.windbornesystems.com/forecasts/version_1/forecast-availability/calculation_times/
