Levels and daily patterns were fairly typical at each ofthe sites on Friday, with a slightly lower than usual daily average at Chapel Hill. A power outage stopped the O’Reilly’s monitor in the late afternoon, but it has now been restarted. (Showing 21 day average up to 29 March in order to show all four sites).
We’re growing the network – if you’d like to host or sponsor a sensor – leave us a message. As we add more sensor sites, comparisons across the urban area will become more robust and informative about Brisbane’s Carbon dioxide emissions.
Daily Averages
For reference, latest monthly average (Feb 2023) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 415.1 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)
