Analysis of Particle Spectral Data from Optical Array (PMS) 1D and 2D Sensors.

摘要

Many flights have been made with PMS sensors through U. S. East Coast deep cyclonic systems, as well as into tropical cloud systems. A full variety of hydrometeor types has been encountered. Many of these aircraft data samples were accompanied by measurements of the radar reflectivity factor by a ground radar just ahead or behind the aircraft, as well as measurements of the water content and particles by other airborne instrumentation. The analysis procedures used to reduce the voluminous particle data collected by the PMS sensors are described, relatively straightforward procedures in the case of the one dimensional data, and more complex procedures for the two-dimensional shadow graphs. The results of some of this analysis are compared with direct and indirect measurements from other sensors.
