cal_sensibleHeatFluxesForCrop

Calculating sensible heat fluxes for crop

Supports the calculation of meteorological characteristics in
evapotranspiration research and reference crop evapotranspiration, and offers
three models to simulate crop evapotranspiration and soil water balance in
the field, including single crop coefficient and dual crop coefficient,
as well as the Shuttleworth-Wallace model. These calculations main refer to
Allen et al.(1998, ISBN:92-5-104219-5), Teh (2006, ISBN:1-58-112-998-X), and
Liu et al.(2006) <doi:10.1016/j.agwat.2006.01.018>.
