The subsections which follow, contain a description <br />of the equipment listed in the Data Inventory, which involved <br />NAWC participation. <br /> <br />2.4.1 <br /> <br />Instrumented Aircraft <br /> <br />A highly instrumented Beechcraft King Air 200T turboprop <br />aircraft, owned and operated by the University of Wyoming, <br />was utilized. It was based at the Prescott, AZ, airport which <br />had excellent navigation facilities permitting all-weather <br />operation. However, the airport lacked adequate snow removal <br />equipment which ultimately caused the airport to close during <br />the storm of February 23-26, when nearly 2 feet of snow fell <br />in the area. Since the airplane was hangared shortly after <br />the storm began and airport service was not resumed until <br />late on February 26, the aircraft was unable to fly throughout <br />most of the storm period. <br /> <br />2.4.2 <br /> <br />Microwave Radiometer <br /> <br />The Bureau of Reclamation microwave radiometer 1S an <br />important and relatively new instrumentation system which <br />can detect the presence and integrated amount of both water <br />vapor and liquid water along its field of view. It is a passive <br />system monitoring incoming natural radiation at 20.6 GHz and <br />31.6 GHz. It provides no ranging information so interpretation <br />of location of the vapor and liquid must be inferred from <br />other data sources. The system is controlled by an LSI-11 <br />computer and the data are recorded on floppy discs and transferred <br /> <br />2-10 <br />
