Petrie Terrace is recording and data should be available again for tomorrow’s update. An unusual feature of the last few days has been the large swings at Bellbird Park – over the last four days its daily average¬† has veered between the 68th, the 21st, the 64th, and the 4th highest of the 71 days this year. (We’re growing the network – if you’d like to host or sponsor a sensorleave 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 (Jan 2023) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 415.0 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)
