Abstract

Modern stations are equipped with batteries of 3-5 shielded storage precipitation gages. The gages, include shields and support stands, are of all metal construction and may be equipped with a clock mechanism capable of running 30 days without attendance and furnishing a record of precipitation, rain or snowfall. The gages are charged with a solution of calcium chloride with a film of oil to prevent freezing or evaporation. The gage stands may be as high as 20 ft. depending on the probable amount of snow depth at the location. A statistical analysis of the records of 47 stations over a 2 year period indicates that the batteries of gages may be reduced from 5 to 3 without loss of accuracy. A classification of hydrological stations is given and mountain snowfall stations are mapped. Detail construction of the metal stands and shields are show in a sketch.
