Latest Data

Monday 16th saw a fairly pronounced gradient of higher CO2 concentration across the 3 sites towards the CBD.  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 (Nov 2022) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 415.4 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)

Day 12 publishing Brisbane CO2 data, re-ordering the plots so that the 21-day average is shown first, as the patterns are clearer than for the more variable daily data.  There are also some minor display improvements to show the half-hourly data-points and improve time axis alignment.  ** Plot for Chapel Hill updated as of 14 Jan 2023 **  We’re growing the network – if you’d like to host or sponsor a sensor – leave us a message.
