DHSVM is a detailed model and one of the major outputs is ET. If you
wanted to supply ET yourself it would take a major recoding effort. My
opinion is that you would be better off selecting a simpler model, whose
complexity is commensurate with the unknowns of your meteorologic data,
or you need to run DHSVM with a range of meteorologic inputs and try to
bracket the uncertainty caused by it.
