A precipitation measuring system comprising a top thermal plate positioned to maximize exposure to falling precipitation and includes at least one ridge circumscribing the top surface for capturing precipitation. The method includes forming a single crystalline silicon layer for a base region on a collector region; and forming a polysilicon layer for an emitter region thereon. The normalized descriptors and signs and symptoms are presented to a user in lists for comparison with a sample in the field. The guide member is arranged on the transparent member at a side downstream of the first position. The computing unit eliminates false puff.
