Radar Coverage Tool
Coverage Tool
This coverage tool calculates from your geographic longitude and latitude on Earth, which radars overlook that position and in roughly which range gate (assuming 45km range gates) and beam the position is. You can choose from a list of other known scientific experiment locations or put your own latitude and longitude in.
If you would like to see an overview of all of the fields of view of the radars, check out our interactive FOV viewer.
Where Are You?
Enter a latitude and longitude to calculate the radar coverage at that location. The tool may take up to 10 seconds to display the radars[1].
Alternatively, you can use the coordinate finder tool to fill in the latitude and longitude field of a specific predetermined location or radar, beam and gate, to find any other coincident radars[2]!

* Geographic longitude and latitude of the geomagnetic poles are correct as of Jan 2021
[1] This tool searches through beam and gate positions, created by using the field of view method in pyDARN, and calculates which beam and gate the location is in using the ray-casting algorithm.
[2] The coordinate finder calculates the latitude and longitude of the center of the beam and gate specified.
[3] Ground range in kilometers is calculated from the haversine formula for great circle distance.
[4] Magnetic coordinates are converted to geographic using the AACGMv2 python library.
Please contact SuperDARN Canada if you use results of this tool in your publications to properly describe, cite and acknowledge the methods used. The tool is intended to be a quick look-up tool for the web. However, the Python and JavaScript code used for calculations is available upon request.
