Meaning

Within day resolution

Driving variables will be read from input file (if defined) at each iteration as specified by the time step of the specific run.

Daily mean values

Driving variables will be read from input file at one occasion only for each day. The input PGraph-structured file is read 00:00 each day and the time point is assumed to be set to 12:00 in the driving variable file. If you have observations once a day, you should chose this setting.

Hourly mean values

Driving variables will be read from input file at one occasion every hour. If you have observations once an hour, you should chose this setting.

10 minute mean values

Driving variables will be read from input file at one occasion every 10 minutes. If you have observations once every 10 minutes, you should chose this setting.

Experience show that “Hourly mean values” reduces the numerical errors on some occations (e.g. for the water balance during the summer) in comparison to “Within day”. It is also worth noting that “Hourly  mean values” resolution reduces the number of eligible options in the simulation.
