The research project was made to investigate drop-sonde mounted optical particle counter in 1997 and 1998. The size-number concentration of atmospheric particles in the upper planetary boundary layer and mid troposphere is essential for studies global geochemical cycles of atmospheric sulfate. However there are few observations due to difficulty of measurements. Prototype of the drop-sonde of optical particle counter was mounted on the airicraft which was used to campaighn of AARMS (Antarctic Airborne Measurment Program), and tested for abalability and feasibility of the counter as dropsonde.The test suggested1. weight of particle counter is 4kg. and enough low to make dropsonde2. counter works under the atmospheric condition temperature range of 2OﾟC-65ﾟC and pressure range of 1OOOhPa-25hPa3. loss of particles due to long inlet pipe was detected in the super micron range particle. but it is not serious problems because drpsonde type optical particle counter will have extremely short length inlet.

1997年和1998年，进行了安装在下投式光学粒子计数器上的研究项目。大气边界层上层和对流层中层颗粒物粒数浓度是研究全球大气硫酸盐地球化学循环的基础。然而，由于测量困难，观察结果很少。将光学粒子计数器落管样机安装在南极航空测量计划（AARMS）的飞行器上，对光学粒子计数器作为落管的可行性进行了试验。粒子计数器重量为4kg。并且足够低，可以制造下投式探空仪2。计数器工作在20 ℃ ~ 65 ℃的大气条件下，压力范围为1000 hPa ~ 25 hPa ~ 3。在超微米范围的颗粒中检测到由于长的入口管造成的颗粒损失。但这不是严重的问题，因为DRPSonde型光学粒子计数器将具有极短长度的入口。
