Brisbane CO2 for 25 December 2023

Latest Data / By

Please see here for details about the calibration improvements made since Phase 2. A much more typical profile for Monday compared to Sunday, with little overall change in average values.  Today’s second figure shows the France-UK Micro Carb satellite arrive in the UK at RAL Space (Rutherford Appleton laboratory) for testing and preparation.  When launched, the satellite’s instruments will monitor Earth’s atmospheric CO2 with extreme precision (~ 1 ppm), and use its Pointing and Calibration System to (amongst other things) point at specific targets on the ground, such as cities, to take local measurements of carbon dioxide emissions from urban areas.  https://www.ralspace.stfc.ac.uk/Pages/CO2-monitoring-satellite-arrives-UK.aspx

Daily Averages – Phase 3

For reference, latest monthly average (August 2023) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 417.1 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)

Brisbane CO2 for 24 December 2023

Latest Data / By

Please see here for details about the calibration improvements made since Phase 2. A rather unusual pattern on Sunday – Chapel Hill and Bellbird Park following a similar profile with large mid-morning ‘spikes’. Values rose across the day at each site. Do carbon dioxide emissions fall when cities depopulate?  Not necessarily.  Today’s second chart shows that even rapidly shrinking (green) and slightly shrinking (yellow) cities in China increased their emissions between 2005 and 2020 – just not as quickly as growing cities. The authors discuss these patterns in light of urban green space, types of economic activity, and factors such as city compactness and polycentricity.

Latest Data / By

Please see here for details about the calibration improvements made since Phase 2. A fairly extreme difference between the sites overnight, with high values at Bellbird Park, quite flat at Petrie Terrace, and bellbird Park again showing a midday risefrom a lower level tha the other sites.  Today’s second chart is a reminder that this year’s global temperatures have reached record levels – data from Berkeley Earth.

For reference, latest monthly average (August 2023) from CSIRO for Kennaook/Cape Grim in NW Tasmania was 417.1 ppm. (Note – these are provisional values, subject to revision folllowing sensor re-calibrations and other checks.)

Brisbane CO2 for 22 December 2023

Latest Data / By

Please see here for details about the calibration improvements made since Phase 2. Friday saw values at Bellbird Park some 13 ppm higher than the previous day, without its periodic midday rise. Not much change at the other sites. Today’s second chart is from an urbanised oasis area of eastern Saudi Arabia with a population of a bit over a million.  The researchers deployed 16 GE Telaire 7001 sensors in five study areas for onemonth during summer.  The relationship between carbon dioxide concentrations and land use was not completely clear, but the highest levels were found in the largest urban area, Al-Hofuf, home to over 850,000 people and most of the area’s traffic.

CO2 concentrations for Phase 2

Brisbane CO2 for 21 December 2023

Latest Data / By

Please see here for details about the calibration improvements made since Phase 2. On Thursday levels rose overall, particularly at Petrie Terrace and Chapel Hill, with Bellbird Park rising towards midnight.  Aircraft contribute to CO2 emissions. Today’s second chart shows imagery of the carbon dioxide (the highly contrasting black and white patches behind the engine) emitted by a Boeing 787 GEnx turbofan engine at take-off.  The authors say that such engines emit 300-400 kg of CO2 each during take-off.
