accurate data

To whom may concern,
We have been checking the air quality index since last year, however we found the data has such a big difference between your website and another official one which is stated on yours as well. I am wondering which one can provide more accurate data, as it will affect the decision for outdoor or indoor. Please help me with this issue. Thank you!
