发明名称 WINTER PRECIPITATION MEASURING SYSTEM
摘要 <p>A winter precipitation measuring system for quantifying the precipitation rate of winter precipitation at a given point on the Earth's surface. The winter precipitation measuring system includes an elongated tube, a thermal plate within the elongated tube, and a method and apparatus for maintaining the thermal plate at a substantially constant temperature relative to a reference plate and for determining a precipitation rate in response to the difference in power consumption required to maintain the thermal plate at a substantially constant temperature.</p>
