Plot S5P CH4 with unit of kilotons

Hi, I’m Pratyush extracted the CH4_column_volume_mixing_ratio_dry_air from S5P data in excel and wants to plot it with the unit of kilotons but it’s present in parts per billion volume. Is there any way to do so? Please help me out to do so…
Thank you

Kilotons itself is not a valid unit. S5P provides column densities, so it provides quantities per squared meter. It is possible to derive mass densities with HARP (derive(CH4_column_density {time} [kg/m2])), but that gives values much less than 1 kg/m2.
Are you perhaps talking about emissions (kg/s)? If so, S5P doesn’t provide emission data.

The problem is that I’m working on a research paper using datasets from EDGAR, TROPOMI, and many more. The methane emission data from EDGAR goes up to 2021, and I want to create more plots from TROPOMI as time series using the same unit—kilotons—as the EDGAR data. Perhaps you could say this for some particular countries. Since you indicated above that I can determine mass densities using that command, what would happen if I multiplied that density number by the area of a nation? I could determine the area by using latitude and longitude bounds, which would finally yield the methane emission measurement in kilograms. However, I worry that rather than the emission value, the methane column may still turn into some kind of variable. Tell me the thing; it will be really beneficial.
Thank you

As I mentioned, S5P does not provide emission information. It just provides information of what is in the air at the time it flies over, which is not the same.
Maybe someone else on the forum can clarify if there is some mechanism to assess emissions based on S5P measurements, but as far as I understood this is far from trivial.
