S5P_L2_CH4, ERROR: cannot keep non-existent variable CH4_column_number_density_avk

[aggiedude]

Trying to convert some S5P_L2_CH4 data to L3 and I am getting this error:

ERROR: cannot keep non-existent variable CH4_column_number_density_avk

when I run this command:

harpconvert --format hdf5 --hdf5-compression 5 -o ch4=bias_corrected -a ‘CH4_column_volume_mixing_ratio_dry_air_validity>50; derive(datetime_stop {time}); bin_spatial(3601, -90, 0.05, 7201, -180, 0.05);squash(time, (latitude_bounds,longitude_bounds));derive(latitude {latitude});derive(longitude {longitude}); keep(datetime_start, latitude, longitude, dry_air_column_number_density, CH4_column_volume_mixing_ratio_dry_air, CH4_column_number_density_avk)’

Any ideas on what I am getting wrong?

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. [image] However, running this code raised error. [image] 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 a…
