Potential transpiration – implicit big leaf

If an implicit single big leaf is simulated the potential transpiration can be read from a PG file or be generated from parameters (see switch “PotTranspInput”). In the latter case the potential transpiration is a sine curve with a fixed maximum potential transpiration, j_max, on a specified day, j_day, and a period of days that transpiration will take place, j_period, i.e. half of these days will be before the maximum transpiration and the rest will be after this day.
