Estimation of ...

Estimation of evapotranspiration can be made from evaporation data, because close relationship exists between the rate of consumptive use by crops and the rate of evaporation from a properly located evaporation pan.
Open "Pan-Evaporimeter" can be used for the same. You will have to put several pans at representative places having uniform characteristics; as the area is large.

Dr. Morey suggestion good. but one needs to know the Pan coefficients depending on the Agroclimatic regions . Also Fetch is another important factor. Apart from that Advection plays a crucial role in ET So the sensible Heat flux need to be monitored . In fact more Microclimate studies needed and will be interesting for students and scientists. Hope Morey will agree.
