The purpose of the gauge network was to provide <br />information on storm precipitation rates and amounts and on <br />spatial variability. <br /> <br />with one exception the standard 30.5 cm capacity gauge <br />mechanisms were operated at all sites with 28.7 cm diameter <br />orifices rather than the standard 20.3 cm (8-inch) orifices. <br />This reduced their capacity to 15.25 cm. but it increased <br />their resolution to 0.13 rom. These gauges used battery-powered <br />clocks with weekly rotation gears. The exception was the <br />Happy jack gauge where improved resolution was achieved with <br />a 45.4 cm orifice (five times standard area) and daily rotation <br /> <br />gears. <br /> <br />All gauges used an antifreeze solution in the catch bucket <br />to convert the falling snow to solution and an oil film on <br />top of the solution to retard evaporation. The gauges were <br />equipped with Alter-I~ type windshields and were located in <br />sheltered clearings in the forest to reduce wind-caused gauge <br />catch underestimates. <br /> <br />The Happy Jack precipitation gauge was serviced after <br />each significant storm, or weekly, whichever occurred first. <br />Most other gauges were serviced approximately weekly. <br /> <br />2.4.8 <br /> <br />Cloud Cameras <br /> <br />A 16 mm time lapse camera was installed and maintained <br />by NAWC at the Payson airport to provide a daytime visual <br />record of clouds over the Mogollon Rim north of Payson. NAWC <br />personnel serviced the site at about 10 day intervals. <br /> <br />2-16 <br />
