Methods of Continuous Particle Sampling by Aircraft

[摘要] Three methods of continuous particle sampling are presented and their merits and defects are discussed one another. One is the replication method. This method had an advantage because it was possible to record ice crystals and water droplets simultaneously, however several precautions were required for the practical operation. Another is the water-blue method. This method was employed without difficulty, and the traces of water droplets were obtained very clearly. For the observation of clouds which had no hydrometeors this was better than the replication method. The other is the photomicrograph method. The use of this method was difficult in flight observations. Continuous airborn samplers were designed for these three methods.From the practical point of view it is advisable to employ those two methods at the sametime.
