Webb: Calculate the mixing ratio of ozone in surface air (z = 0 km, P = 1000 hPa, T = 290 K). Compare with the air quality standard! c: Why is the ratio between the concentrations at and 25 km altitude 0 larger expressed in mixing ratio than in number density (like in fig. 1-1)? d: The O 3 column expresses the total number of ozone molecules per WebIts mixing ratio is almost homogeneous in the troposphere and the stratosphere. The presence of carbon dioxide is strongly linked to life on Earth. CO 2 is actually necessary for plant growth, since the carbon in plants and animals originates exclusively from atmospheric CO 2 .
