Brisbane CO2 for 24 November 2023
The notable feature for Thursday was the convergence by day’s end of all three sites at a similar lower level, about 10 ppm above background levels for well-mixed air. Higher than average winds from the north-east may have been a driver. Please see here for details about the calibration improvements made since Phase 2. Yesterday’s second figure showed the CO2 concentration in the stack plume from a Taiwanese coal-fired power station – and today’s is a similar plot from a Chinese research collaboration who flew a sensor-equipped drone through the plume from a gas-fired power plant in Shenzhen.
