Gas detection

  1. I am looking for a way to map gases over a city, what are some ways I could do that? This is a theoretical experiment so cost is not an issue. Thanks in advance

    Use a gas detector and a GPS.
  4. What sort ppm can I get something like that? And also how does said gas detector work?
