ABSTRACT:
A weather instrumentation station including a louvered instrument housing containing weather instruments. An exterior double-walled housing radiation shield is disposed over the instrument housing in spaced relation thereto to shield the instrument housing from the sun. A double-walled auxiliary shield may be positioned over at least one open side of the housing shield in spaced relation thereto to shield sun rays from the instrument housing on such open side. The housing shield and the auxiliary shield inner walls are formed of thermoplastic or aluminized asbestos material, and the outer walls of stainless steel. The housing shield roof is peaked to forestall accumulation of water and snow thereon. The instrumentation station may have a chimney to increase interior air circulation.
There is also provided a rainwater gauge including a rainwater receiving flask with a funnel disposed over the flask to channel rainwater therein. The ratio of the area of the funnel top inlet opening to its lower outlet opening is preferably ten to one. An elongated, hollow, open-ended, stainless steel cylinder of minimal length may be detachably connected to the perimeter of the funnel upper inlet opening to channel rainwater to the funnel lower outlet opening. The cylinder upper edge may be a knife edge to ensure collecting a precise area of rainwater. The cylinder interior surface is coated with a hydrophobic material and the cylinder lower edge is a knife edge to overcome the surface tension of water droplets and thus ease their passage through the cylinder.
