About this document
Rohwer by Ken Jeroen Pacleta is a document available to read on EtoBox.
Rohwer developed an empirical formula for pan evaporation based on experiments in Colorado at 5,000 feet elevation. The formula accounts for atmospheric pressure and elevation. It calculates evaporation as a function of barometric pressure, vapor pressure at the water surface and dew point, and wind velocity. Later, Penman modified the formula by substituting wind speed measured at 2 meters instead of at ground level.
