Short summary

We compared v3.0B of the BEHR satellite NO₂ product against independent measurements to verify its accuracy. We found that the BEHR product generally performs better than standard NO₂ products and the previous version of BEHR. Outside of the SE US, using daily NO₂ profiles results in similar or better agreement with independent measurements than using monthly profiles, and direct evaluation of those profiles shows they better describe NO₂ distribution in urban areas than monthly profiles.
