<p>I was working with SO2 column data product from <a href="https://disc.gsfc.nasa.gov/datasets/OMSO2_003/summary?keywords=OMI%20Total%20Column%201-Orbit%20L2%20Swath" rel="nofollow noreferrer">https://disc.gsfc.nasa.gov/datasets/OMSO2_003/summary?keywords=OMI%20Total%20Column%201-Orbit%20L2%20Swath</a>
I wanted to know, is the cloudfraction data in SO2 column an accurate measure of the Sulphur Dioxide present in an area?</p>

No, cloud fraction is not a good measure of $\ce{SO\_2}$. Clouds are functions of moisture, temperature, and cloud condensation nuclei. Som of the other variables, such as (but not limited to) `ColumnAmountSO2` or `ColumnAmountSO2_TRL`are better indicators.
