How to get the LUT file #30

Open Kexin828 opened 9 months ago

Kexin828 commented 9 months ago

s5p.utils.py:

read lut

lut_pattern = os.path.join(s5p_nc_dir, 'S5P_OPER_LUT_NO2AMF*')
lut = xr.open_mfdataset(lut_pattern, combine='by_coords')

Where can I download this LUT file? I would be grateful for your answer.

Here's the global attributes of that nc file named S5P_OPER_LUT_NO2AMF_00000000T000000_99999999T999999_20160527T173500.nc:

// global attributes:
        :validity_stop = "99999999T999999" ;
        :dataset_name = "S5P_LUT_NO2AMF" ;
        :author = "Alba Lorente" ;
        :contact = "Folkert Boersma. boersma@knmi.nl    " ;
        :history = "20160530. Version 02.5. Corrected DAK box AMFs with McArtim to account for sphericity atmosphere." ;

You can contact Folkert for the LUT ;)
