2/11/2014 9:00 AM 0.00 0.0 M M M The standard rain gauge used by CoCoRaHS has a physical surface property which suggests a minor bias in rainfall capture. Over the past few days here, it rained heavily and nearly constantly at my location. Upon emptying the gauge, the physical surface properties the plastic of which the gauge is made are such that some residual moisture remains on the surface of the funnel, and both tubes, and this thin layer of water can affect measurement. Upon emptying the gauge, I drained the tubes bud did not wipe them dry. Making this observation, I then refrained from wiping the gauge dry over this rainy period after each emptying. At the end of the rainy period, a total of 0.02 inches was measured in the gauge a day even though no precipitation had occurred for the previous 24 hour period; this amount was the result of that little film of water that seems to adhere to the type of plastic in the gauge eventually moving under gravity and thus being measured. This bias would seem to be about 0.3% (0.02/5.57 total). The bias could be overcome by weighing a cleaned and dry gauge after each measurement.
