This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. Doppler radar can see not only the precipitation in a thunderstorm (through its ability to reflect microwave energy, or reflectivity), but motion of the precipitation along the radar beam.In other words, it can measure how fast rain or hail is moving toward or away from the radar.
