Harpmerge doesn't work anymore with TROPOMI SO2 L2

HARP
1

I was using harpmerge (1.29, conda installation) to create gridded netcdf files from L2 orbit data.
In the end of 2025, the format of L2 data has been changed, and now I have error (when I tried to apply “SO2_column_number_density_validity>50“):

ERROR: record does not contain a field named ‘sulfurdioxide_total_air_mass_factor_polluted_precision’

I checked S5P MPC Product Readme SO2 V02.08.00 of ESA and there is information that:

”Items removed in the new release Variables removed from /PRODUCT/SUPPORT_DATA/DETAILED_RESULTS/ group:
• sulfurdioxide_total_air_mass_factor_polluted_precision”

So, obviously harpmerge won’t work.

Are you planning to fix it in your next harp release (especially as a conda package)?
And it would be great to have it soon… thanks in advance!

Are you sure you are using the right HARP version? This should have already been resolved in HARP v1.28.

Thanks! It turned out that in my script my older conda environment with harp 1.25 activated during the run. So now all works, I have version 1.30.
Sorry for confusing and thanks again.
