Design of Data Processing Software for Raindrop Spectrometer Based on LabVIEW

This paper studies design of data processing software for raindrop spectrometer. It includes reading, decompression, data processing, storage and display. The difficulties are data decompression and the software architecture design. This software applies digital image processing technology to process the raindrop data measured by dual-line raindrop spectrometer data processing software (DRDPS) based on LabVIEW, realizes the display from data file to particle image, stores the obtained information and geometric parameters of precipitation particles, and the obtained meteorological information of precipitation intensity, precipitation particle shape, precipitation type and precipitation particle spectrum is displayed in the front panel of the software. The test results show that the software meets the system requirements completely and can be applied to the research of cloud precipitation and other atmospheric science relevant fields.
