| Popis: | The main parameters of optical channels of an optoelectronic dual-channel precipitation gage are described, as well as results of laboratory experiments and preliminary field tests. A procedure is suggested for calculating the calibration parameters using 5.01-mm steel balls; it allows minimizing the error caused by imperfections in the optical system of the device. The results of liquid volume measurements show that the laboratory precipitation measurement error does not exceed 5%. Preliminary results of field measurements are shown in the form of size distributions of precipitation particles, variations in the intensity, and the total precipitation calculated. |
