A recording evaporimeter
The instrument herein described was originally designed and built to record the evaporation‐loss from a standard Weather Bureau pan for use in a study of the variation of flow in Santa Ana River. Valuable suggestions were made by various members of the Water Resources Branch of the Geological Survey in Southern California, and financial assistance for construction was given by F. C. Ebert and H. C. Troxell of the same organization. The typing of the paper and some of the drafting were done by Works Progress Administration help.
The original instrument was damaged by flood‐waters in 1934, while in operation at Baldwin Park, California. It was then redesigned and constructed of stainless materials and installed on the campus of the San Bernardino Valley Junior College. The Weather Bureau pan was replaced by a thermally insulated pan. The damping unit was added at this time by the present writers. The evaporimeter was placed in regular operation on October 30, 1937, in a study of the relative magnitudes of the various energy‐components associated with solar and sky radiation and with evaporation from water‐surfaces, from damp soil, and from plants.
