Keep averaging kernel variables

Hello,
I would like to compare S5P HCHO with model simulated results.
For comparing simulated and observed results, I need averaging kernel.
So I tried converting L2 tropospheric_HCHO_column_number_density_avk variable into L3 grid by following code.


However, running this code raised error.

I also tried running this code without specifying variables in keep() parameter, but resulting L3 files do not contain tropospheric_HCHO_column_number_density_avk variable.
Is there any method to convert tropospheric_HCHO_column_number_density_avk variable into L3 grid?
Thanks in advance.

You should never regrid averaging kernels. See also this topic.
