The interception storage and process was mixed up between canopies in version from March 2019. The lowest layers of canopies was disregarded in the scheeme below:
However, the evaporation rate from the lower layers was still assigned to values but not to the correct ones. Instead the values of evaporation from interception storage of additional canopies was mixed with the first plant canopies. In new corrected version the height of the canopies are considered correctly independent of index on the different plants. This is both for dynamic and for static type of plants.
Thanks to Bernd Schultze from Udata in Germany that find the problem.
