Weather Map Data (EWN GIS platform)

EWN can provide data from our internal GIS Platform via API for the following components:

  • Severe Weather and Natural Hazard Alerts across Australia
  • National EWN High Resolution (Volumetric) Radar across the Australian BOM radar network
  • Tropical Cyclone Tracking
  • Rain gauges
  • River gauges
  • Automatic Weather Stations (AWS) Observations
  • The GIS layers API is set up for server to server access and is not fit for direct to client responses with a limit of feed requests once per 2 minutes for each endpoint

    Live Hail Alerting 

     

    Using our new Australia first hail algorithms, EWN can now provide targets cell specific hail alerts and polygons where large hail has been detected.  

    The EWN Hail Alerting system monitors all weather radars (BOM owned) across Australia and scans for the detection of hail at all heights of the atmosphere.  

    Upon any storm where large hail is detected (2cm +), EWN Alert Operators will confirm it is a true reading and send out an immediate Hail Alert Polygon. The Hail Alert includes where the storm is, the size of the largest hail stones and the areas to be impacted over the next 30 to 60 minutes. 

    The image on the left shows EWN Hail software detecting large hail in numerous storms across the Greater Sydney Region. Hail markers are shown as triangles with the size in cms of the largest hail inside the triangle.  Purple markers indicate giant hail.  Directional arrows show the direction of the hail and allow for EWN staff to draw polygons and send a hail alert to clients via API. 

    The image on the right shows a cross section of the storm allowing EWN staff to view where the hail is and the set-up of the storm.

    EWN Lightning Network API 

     

    The EWN Lightning Network uses a series of Long-Range Detection points allowing for a truly accurate and clear picture of lightning across Australia and New Zealand. 

    Individual lightning discharges are captured in near real-time by a central processor that aggregates sensor data from the entire network. Using electronics sensitive to the Very Low Frequency (VLF) band, each sensor can detect lightning discharges with an astonishing 1KM lightning location accuracy.

     

    EWN Lightning Services 

    The EWN Lightning Network is one of the most accurate systems covering Australia and in recent testing, picked up over double the amount of lightning than some other networks. 

    The added ability of being able to detect cloud to cloud lightning provides users in most cases with an advanced warning before cloud to ground lightning occurs. Besides safety, this ability improves operational efficiency, such as with transportation route optimization and accurate warnings 

    The EWN Lightning Network is available to organisations via an API feed in JSON format allowing you to plug the data directly into your own software web-based applications.

    In order to use the API you will need an API Key which EWN can provide.
