Bugs in technical Paper Example Notebooks

Start with the example notebooks NB1 through NB4 and the linked eWaterCycle issue 355. Reproduce the reported failures in NB1, NB2, NB3, and NB4, including the ESMValTool, input/output, and globalOptions errors; done means the affected notebook steps run without these errors.

I checked the Example Notebooks, and found some bugs:

• 1.The main problem is still the issue with generating forcing using ESMValTool (see this issue). There seems to be something wrong with the temperature data. This is the log that I get from example NB1:

      ERROR   [3482181] Failed to run preprocessor function 'save' on the data
      [<iris 'Cube' of air_temperature / (K) (time: 10592; latitude: 9; longitude: 7)>]

      (and 26 further file(s) not shown here; refer to the debug log for a full list)
      with function argument(s)

• 2. When I run this in NB2:

      cfg_file, cfg_dir = model.setup(end_time=experiment_end_date)
  

And this in NB3:

      observations_df, metadata = ewatercycle.observation.grdc.get_grdc_data(
          station_id,
          start_time=experiment_start_date,
          end_time=experiment_end_date,
      )

I get an [Errno 5] Input/output error. (Is this related to the disk space?)

• 3. In NB4, when I run this:

    reference = ewatercycle.models.PCRGlobWB(version="setters", parameter_set=experiment_parameterset)
  

I get the following error: NoSectionError: No section: 'globalOptions'.
