estimate_Rs_for_islandLocations

For island locations, where the land mass has a width
 perpendicular to the coastline of 20 km or less, the air masses influencing
 the atmospheric conditions are dominated by the adjacent water body in all
 directions. The temperature method is not appropriate for this situation.
 Where radiation data from another location on the island are not available,
 a first estimate of the monthly solar average can be obtained from the
 empirical relation.

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>.
