In 2011, NASA Glenns Icing Research Tunnel underwent a major modification to its refrigeration plant and heat exchanger. This paper presents the results of the subsequent full cloud calibration. Details of the calibration procedure and results are presented herein. The steps include developing a nozzle transfer map, establishing a uniform cloud, conducting a drop sizing calibration and finally a liquid water content calibration. The goal of the calibration is to develop a uniform cloud, and to build a transfer map from the inputs of air speed, spray bar atomizing air pressure and water pressure to the output of median volumetric droplet diameter and liquid water content. 激光相位多普勒干涉儀LDV，PDI，PDPA，PDA Artium PDI-FP 雙量程可機(jī)載飛行探頭 激光誘導(dǎo)白熾光（LII）煙氣分析儀
