pyart.util.sphere_distance

pyart.util.sphere_distance(radar_latitude, target_latitude, radar_longitude, target_longitude)

Calculated of the great circle distance between radar and target

Assumptions

Radius of the Earth = 6371 km / 6371000 meters Distance is calculated for a smooth sphere Radar and Target are at the same altitude (need to check)

Parameter

radar_latitudefloat, [degrees]

latitude of the radar in degrees

target_latitudefloat, [degrees]

latitude of the target in degrees

radar_longitudefloat, [degrees]

longitude of the radar in degrees

target_longitudefloat, [degrees]

longitude of the target in degress

returns:

distance (float, [meters]) – Great-Circle Distance between radar and target in meters
