Maybe I'm missing this info somewhere, but would like to better understand the accuracy of the placement of the markers on the map. For example there's a 702 ppm marker in Moorestown Township NJ. Is this the exact location of one sensor, and would this then mean that some entity in Moorestown NJ is producing tons of co2?
- ahaucnx 2y agoAll data is crowd sourced from people that purchased our open-source outdoor monitor Open Air [1] either as a kit or the fully assembled version. Once the monitor is operating, the user can opt-in to make the data public and enter longitude and latitude of the location. Then it will appear as that spot on the map. If people have privacy concerns we recommend them to just move the location a bit off from their exact one. A level of 702ppm is not necessarily an indicator for an emission source. There are quite substantial natural diurnal cycles, especially in the country side as plants emit CO2 in the night. We have observerd peaks with up to 800ppm just based on that. I think a common misconception is around climate change that we believe that the 430ppm that we currently have is very constant across the atmosphere when in reality it can have substantial variations.
