Description Usage Arguments Value Author(s) See Also Examples
Produce plot of aggregated estimations of evapotranspiration in daily, monthly and annual steps, or averaged daily estimations in monthly or annual steps.

results |
A list named |
type |
A character string of either |
OBS |
A list named |
OBSplot |
Must be eith TRUE or FALSE. TRUE indicates that the observed evaporation will be plotted together with the estimations and FALSE indicates that the observations will not be shown on the plots. |
Sdate |
Only used when type = |
Edate |
Only used when type = |
If argument type
is Aggregation
, three plots are displayed in the following order (the next one appears after pressing enter):
1) Daily evapotranspiration estimates;
2) Monthly evapotranspiration estimates aggregated from daily estimates;
3) Annual evapotranspiration estimates aggregated from daily estimates.
If argument type
is Average
, two plots are displayed in the following order
1) Monthly averaged daily estimations of evapotranspiration;
2) Annually averaged daily estiamtions of evapotranspriation.

Penman Open-water Evaporation
Evaporative surface: water, albedo = 0.08 ; roughness height = 0.001 m
Sunshine hour data have been used for calculating incoming solar radiation
Wind data have been used for calculating the Penman evaporation. Penman 1948 wind function has been used.
