This image shows a coal-fired power plant in the mountains emitting CO2, where a measuring device on the chimney gauges CO2 concentration. A spherical bubble displays the major parameters affecting measurement accuracy, particulate matter, temperature, relative humidity, and pressure, and provides a comprehensive correction formula for CO2 concentration.
