Abstract:

The dependence of the optical precipitation gauge calibration results on the dimensions of the reference objects is analyzed. The ways to optimize the calibration procedure are suggested, including: reducing the number of calibration zones; use of calibration factors instead of correction parameters; additional calibration with balls with a diameter of 1 mm; use  of the coefficients depending on the measured diameter for particles smaller than 2 mm. The conclusion is made about the effectiveness of the calibration procedure suggested for the optoelectronic devices designed to measure the size of small particles, for example, a snowstorm parameter gauge.

Keywords:

optical precipitation gauge, calibration, drop size, snowstorm parameter gauge
