HailCam: An Automated Imaging System for Real-Time Measurement of Hail Size Distributions and Fall Rates

Co-located field intercomparisons were conducted at the Weining Hail Suppression Experimental Base of the China Meteorological Administration (CMA), located in Guizhou Province (26.9°N, 104.9°E). This study area is characterized by typical karst terrain with rugged relief and frequent severe convective weather, posing rigorous practical tests for the stability, anti-interference and detection accuracy of hail observation instruments in complex underlying surface environments. A co-located OTT Parsivel² laser disdrometer (hereinafter referred to as disdrometer) was deployed alongside the HailCam system as the reference instrument.本研究在中国气象局（China Meteorological Administration，CMA）威宁防雹试验基地开展了同址野外比对试验，该基地位于贵州省（北纬26.9°，东经104.9°）。该研究区域属典型喀斯特地貌，地形起伏崎岖且强对流天气频发，可为复杂下垫面环境下冰雹观测仪器的稳定性、抗干扰能力与探测精度提供严苛的实际性能检验。本次试验将OTT Parsivel²激光雨滴谱仪（以下简称雨滴谱仪）作为参考仪器，与HailCam系统同步布设。
