Abstract

The invention discloses a correcting method for measuring errors of a laser raindrop disdrometer. The correcting method can be used for overcoming the measuring errors due to a photoelectric technology adopted by the exiting laser raindrop disdrometer, remarkably improving rainfall quantitative measurement precision of the laser raindrop disdrometer, and obviously improving radar reflectivity factor calculating accuracy, so that the quantitative application field of the laser raindrop disdrometer is expanded. The correcting method can be used for optical rain gauges adopting other similarity principles.

Description

technical field [0001] The invention belongs to the fields of atmospheric science and hydrology, and in particular relates to the measurement error correction of a laser raindrop spectrometer for measuring precipitation and an optical rain gauge with the same measurement principle. Background technique [0002] The laser raindrop spectrometer can measure falling rain, snow, hail and other precipitation, so as to calculate the rain intensity, rainfall and radar reflectivity factors of various rainfall types. In recent years, with the introduction of laser raindrop spectrometers in Germany, the United States and other countries, and the emergence of domestic laser raindrop spectrometers, various laser raindrop spectrometers have been widely used in my country's traffic control, meteorological monitoring and services, scientific research, airport observation , highway meteorological monitoring, hydrogeography, weather radar data correction and other application fields.
