NO2 is also produced by diesel and gasoline combustion and is a significant pollutant in most cities; its value changes during the day (Windy.com has this info if you are curious). I don't see that the author is controlling for the outside value. Some of the variance could be regional air quality (e.g. the low values around Christmas).
- nickkell 5y agoSo why would there be spikes during the night? And how do you explain the dip on days when they don’t cook?
- ericbarrett 5y agoI don't know, but actually (again, according to Windy) NO2 spikes at night across the U.S., but less on weekends. Industrial processes? Furnaces? Weather? Bad data? This is why they should have an "outside" control away from any house exhausts. I'm also not saying the gas stove has no effect, just that they don't seem to be controlling for ambient NO2.
