Reference
(G) Goudriaan, Modeling Potential Crop Growth Processes, 1994, (revised version Nov. 2004)
Calculated daylength, photoperiodic daylength, solar constant and
daily total effective solar height for each DOY for a set of given latitudes.
For each row in the resource it creates 366 rows containing values for
each day of year (DOY)
The transformer needs the field names of a resource, that contain
- location id
- latitude in decimal degrees
- inclination of sun angle in decimal degrees
Normally you do not enter the numeric value for latitude, but a reference to the
value, i. e. the column name of the resource's column containing the latitudes.
