The β-ray gauge as a leaf surface wetness detector

Surface wetness duration was measured by a β-ray gauge as a function of wind velocity in the laboratory. Determination of mass transfer obtained from these results agreed well with a standard theoretical relationship for laminar flow over a flat plate. The β-ray gauge was field tested as a dewmeter...

Summary:Surface wetness duration was measured by a β-ray gauge as a function of wind velocity in the laboratory. Determination of mass transfer obtained from these results agreed well with a standard theoretical relationship for laminar flow over a flat plate. The β-ray gauge was field tested as a dewmeter over a wax bean canopy.
