CAEP: Evaporation Pans
The Class A Evaporation Pan is a standard Bureau of Meteorology Class A type for measurement of water evaporation. It is normally installed on a wooden platform set on the ground in a grassy location. The pan is filled with water and exposed to represent an open body of water. The pan is filled within 60mm of the top of the pan. The evaporation rate can be measured by manual readings or with an analog output evaporation gauge.
