*Try to do all of this data gathering at once. I have this column so we can think about what is going on. For example, rush hour at 7:30 am in San Antonio (highest NOx/VOC) will still be 4:00 am in Los Angeles, CA…no traffic yet. This makes a difference to note.
**These AQI data are on the 0 – 500 AQI scale, they are not actual ppb or µg/m3 measurements.
