This will be discussed <br />further in a later section. <br /> <br />C. Jackson Creek ObservatorY <br /> <br />A high elevation observatory (1951 m) will be established near <br />the Jackson Creek (JCC) precipitation gauge site. This site will <br />be used to monitor seeding effects within the target area and to <br />monitor for the presence of the tracer SF6 during seeding <br />operations. The observing equipment will consist of a dual <br />channel microwave radiometer, a ground microphysics laboratory, <br />and a continuous SF6 detector. These observational tools will be <br />run simultaneously. A two man crew will be necessary to operate <br />all the equipment. <br /> <br />1.0 Microphvsics Laboratorv <br /> <br />The microphysics equipment will include: <br /> <br />a) an aspirated PMS (Particle Measuring System) 2D- <br />cloud probe used to record hundreds of two-dimensional <br />snow crystal images per second. Images are recorded to <br />magnetic tape which can be processed to determine <br />crystal sizes and concentrations. Meteorological <br />variables of state are recorded every ten seconds. The <br />data tapes will be processed by USBR. <br /> <br />~ <br /> <br />22 <br />
