PMS Precipitation Probe Inter-comparisons and Correlations with Radar Measurements.

摘要

Two versions of PMS precipitation probes are compared from simulataneous spectrum measurements. Systematic probe differences reveal undersizing and depth-of-field problems with the 'wide-arm' (4500 micrometers) probe. Radar comparisons with the aircraft data substatiate the deduced problems and quantitative correction procedures are developed and demonstrated for the 'wide-arm' probe. Instances of very large radar discrepancies are shown to be caused in part by poor selection of particle phase and/or habit. (Author)
