Small Ice Detector Version 2 (SID-2H) Data. Version 1.0

This dataset contains SID2H data collected during the ADELE/SPRITE/HEFT09 project. The Small Ice Detector, Version 2 (SID2H) is a particle light-scattering instrument for measuring size distributions of particles in the 1 to 70 micrometer size range and for discriminating between ice crystals and supercooled water droplets in mixed phase clouds. SID2H measures the intensity of light scattered by cloud particles in the forward direction. Measurements are recorded for each particle that crosses the instrument's laser beam. The SID2H data files are binary and come in 10-minute blocks; a new file is created every 10 minutes. Data records include timing events, light scattering intensity, and housekeeping (temperatures, laser power, etc.). The file structure has a header, data, and a footer.本数据集包含ADELE/SPRITE/HEFT09项目期间采集的SID2H数据。小型冰粒探测器第2版（Small Ice Detector Version 2）是一款粒子光散射仪器，可用于测量1至70微米粒径范围内的粒子粒径分布，并能区分混合相云中的冰晶与过冷水滴。SID2H可测量云粒子在前向散射的光强，每当有粒子穿过仪器的激光束时，系统便会记录对应测量数据。SID2H的数据文件为二进制格式，且以10分钟为一个数据块；每10分钟便会生成一个新的数据文件。数据记录包含时序事件、光散射强度以及设备内务参数（如温度、激光功率等）。该文件结构包含文件头、数据段与文件尾三部分。
