2021-04-10 · Daily average CO 2 values are computed from selected hourly values that satisfy 'background' conditions, i.e. stability and persistence of CO 2 concentrations (read below for more information). That means the daily averages shown on the plot are likely computed from a subset of the hourly averages. Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for. The conversion from mg/Nm3 to ppm is done according the following formula: (mg/Nm3) * (22.4/MW) = ppm where MW is the molecular weight of the gas.
