WeatherSentry Web Services

Version 52



    WeatherSentry® Web Services from Schneider Electric provides your organization with the highly accurate weather observations and forecasts relied on worldwide to protect people, resources and profitability. These forecasts are top ranked by the independent agency as the most accurate among industry providers.


    Our global weather observations and forecasts empower situational awareness applications by providing a clear view of near-term forecasts, and current and recent weather, including valuable weather content not often available through other services (such as lightning strikes). With our highly accurate, web-delivered weather data, you can optimize operational decisions through improved visualization, by integrating valuable GIS or point-based weather data into your critical applications and websites.


    Your weather information your way


    Request data based on the needs of your application, or expand the capabilities of your application by incorporating a variety of weather information. These web services permit the retrieval of data using the REST standard.




    Observed data is the record of atmospheric conditions. The observed value is measured at a point in time, or instantaneous, for most parameters – with the exception of precipitation. Precipitation is typically reported as a measurement over a period of time, or accumulated.


    Observed weather values are reported hourly. Traditionally, the hourly report refers to the instantaneous value from top-of-the-hour readings. Precipitation values have duration and therefore are allowed to accumulate until reported at the end-of-the-hour. Observed data is available for a specified location for the past 60 UTC days.


    The normals provided are a 10 year average of high temperatures and/or low temperatures. Daily departures from normal are also available. Quality control occurs within the hour and again within the day. To ensure the most accurate possible observation data, allow at least 8 hours past midnight for completion of quality control.

    A forecast is the prediction of the weather using the principles of physics and meteorology. Forecasts of temperature and other similar data are instantaneous – meaning they are forecast for a specific time. Precipitation values have duration and are therefore represented as an accumulation expected by the end-of-the-hour. The forecast process supports up to 15 days of hourly and daily data. Forecast data is provided for a specified location and is updated every hour.


    Forecast information can come directly from a nearby official station, or if you prefer it can be an interpolated result which is taken from a combination of data from nearby stations.

    Historical observations


    Historical daily observation data are available worldwide for time periods up to 5 years from the current day. These data include most observations already available in daily observations.


    The dirty little secret : Unlike other weather providers, our historical observation data have undergone (and are continuously undergoing) a rigorous cleaning process to remove the bad and nonsensical data that is often associated with both public and private observation data. Don't waste your time sifting through questionable data. Get it from the vendor you can trust.

    Weather stations


    When you need atmospheric data directly from the source, you want weather station data. Through our WeatherSentry web service you have direct access thousands of both public and private stations around the globe*. You can query stations directly using a stations identifier (StationID) or you can locate stations using a spatial query (x,y) or postal code. WeatherSentry web services will guide you to approved stations that have only the best data, or you can choose to use any of the other stations out there that haven't made our cut on quality and reliability but provide data you are looking for


    *Private station access depends on your subscription and the access rights allowed for the given station. For example, some stations may only be visible to you.

    Map layers


    We have over 1,200 layers that can be directly integrated into your geographic information systems (GIS) or simply layered on top of a basemap. If you are looking for discrete geospatial weather data that you can integrate with other spatial assets, or if you are simply looking for a visualization of current or past data, we have it. Some of the more popular layers are listed below:


      • Lightning (updated at least every 5 minutes)
      • Storm corridors (updated ~30 minutes)
      • Weather station observations (updated ~60 minutes)
      • Severe weather bulletins (as provided)
      • Storm reports (as provided)
      • Tropical storm forecasts (as provided)
      • Radar (observed precipitation) (updated ~30 minutes)
      • Satellite (clouds) (updated ~30 minutes)
      • Precipitation forecast (updated ~30 minutes)
      • Pavement temperature observations (updated ~30 minutes)

    What type of layers do I need?

    Our layers come in two flavors. Our web mapping service (WMS) serves up image tiles that are laid on top of a basemap and rendered (e.g. radar is a good example of this). Our web feature service (WFS) delivers each of the weather data elements as specific features with rich attribute information. Choose a service type based on your specific requirements. 


    Layer TypeApplicationBest for
    Web Mapping Layer (WMS Service)VisualizationOperational dashboards, map making and publishing, overviews and overlays
    Web Feature Layer (WFS Service)Integration with other spatial assetsSimple to sophisticated query and analytics using recent or current weather data. Understanding precisely where a weather element is in relation to other spatial features around you


    Both services provide weather content according to OGC (Open Geospatial Consortium) standards.
