Hi Alana, Temperature and humidity have no effect on the levels of NO2 in the atmosphere. What will increase NO2 is plant material and vehicle emissions. Also light energy can increase products of NO2 reactions such as NO3, N2O5, and HNO3. Temperature and humidity do, however, may have an affect on the method you use to test NO2, depending on the type of detector. High humidity (often associated with high temperature) may fog the detector inside and produce a less efficient reading. Hope this helps and good luck with your project!
