The meteo_proc gapfilling step has hard-coded variables to be filled and the drivers for each of the variables. To make the tool more flexible, e.g., to enable site-specific driver variable selection, the driver variables and the tolerances for each variable need to be changed to parameters.

For now, we'll add these as parameters to the command line calls of meteo_proc, similarly to what was done for gf_mds.

Steps to consider/complete:

• Clarify how tolerance min/max are used in code; are the tolerances only specifying how much a value can change from one data point to the next or anything else?
• Check and confirm if date and rows_min are needed
• Confirm the default values continue to be the same as the currently hard-coded values
• Add tolerances applied to the code in the ‘printf’ that populates the log files for the meteo_proc step (e.g., for TA in dataset.c)

The configurations for the call with the parameters will come from a configuration file passed to the main ONEFlux call, to be handled in the scope Issue #75. Also related to Issue #43.
