E_JensenHaise: Lake evaporation (Jensen-Haise method)
In jmerc13/LakeIsodrology: Lake isotope hydrology

E_JensenHaise returns the daily rate of evaporation, E (mm/day), given the air temperature and solar radiation.

1	E_JensenHaise(Ta, Qs, a = 0.014, b = 0.37, c = 0.03523)

`Ta`	Air temperature, T_{a} (C).
`Qs`	Solar radiation, Q_{s} (W m^{-2}).
`a`	Empirical parameter, assumed to be 0.014.
`b`	Empirical parameter, assumed to be 0.37.
`c`	Empirical parameter, assumed to be 0.03523.

Evaporation as determined by (Jensen and Haise 1963, McGuinness and Bordne 1972, Rosenberry et al. 2007):

E = (a T_{a} - b)(Q_{s} c)

Note that this method is very closely related to that of Stephens and Stewart (1963), the major difference being the value of the assumed parameters. For Stephens and Stewart the values of a, b, and c are 0.0082, 0.19, and 3.495e-2, respectively.
