In pyaeroval_config.py: regrid_res_deg is expected to be a float (not a dictionary)

[DirkOlivie]

General

• When I run python pyaeroval_config.py, it stopped after +/2 minutes.
• In pyaeroval_config.py, regridding for MODIS was defined with a dictionary :

regrid_res_deg={  # Regridding of the data
        "lat_res_deg": 5,
        "lon_res_deg": 5,
    }

• However, when running there was an error message (see below) that regrid_res_deg should just be a float.

Describe the bug

• Pyaerocom version:
• Computing platform: ppi
• Error message:

pydantic_core._pydantic_core.ValidationError: 1 validation error for ColocationSetup
regrid_res_deg
  Input should be a valid number [type=float_type, input_value={'lat_res_deg': 5, 'lon_res_deg': 5}, input_type=dict]

• Configuration file (pyaeroval_config.py):

MODIS = dict(
    obs_id="MODIS6.1terra.DT.DP.mean",  # Observation ID of know network
    web_interface_name="Modis",  # Name that is displayed on the webpage
    obs_vars=["od550aer"],  # List of variables that is to be evaluated
    obs_vert_type="Column",  # Observation level
    regrid_res_deg={  # Regridding of the data
        "lat_res_deg": 5,
        "lon_res_deg": 5,
    },
    ts_type="daily",  # Frequency of read observations. Evaluation can not be finer than this, for this network
)

To Reproduce

1. ssh ppi-r8login-b1.int.met.no
2. qlogin -l h_rss=8G,mem_free=8G,h_data=8G
3. module use /modules/MET/rhel8/user-modules/fou-kl
4. module load aerotools
5. cd kurse-AeroTools/scripts
6. python pyaeroval_config.py

Additional context
I have done two tests (one with commenting out regrid_res_deg, and one with setting regrid_res_deg=5 in pyaeroval_config.py), and in both cases it then worked well.
