the use guide of TROPOMI SO2 SBR terrascope L3 product

Hi terrascope community,      I noticed that VMs  had updated the SO2 SBR product, in the location "/data/MTDA/TERRASCOPE_Sentinel5P/L3_SO2CBR_TM_V2/". But it lacks  documents for explaing the tiff file, including the units and scale. So could you fill this on the docs in terrascope website(https://docs.terrascope.be/). many thanks!
