A kilogram = .00110231 tons ref. google
Global distribution of atmospheric water ref. water.usgs.gov
3,094 Cubic miles or 12,900 cubic kilometers
Thus there are 12,900 e+9 cubic meters of H20 in the atmosphere.
or 12.9 e+12 cubic meters H20 in the atmosphere.
1 US short ton of water (sh tn wt.) = 0.91 cubic meters of water (m3 - cu m)
Thus a cubic meter of water = 1.099 tons
There are 12.9 e+12 cubic meters H20 * 1.099 tons of H20 in the atmosphere
or 14.177 e+12 tons of H20 in the atmosphere
That is 14,177 gigatons of H20 in the atmosphere.
How much CO2 by weight in the atmosphere?
“The total mean mass of the atmosphere is 5.1480×1018 kg. ref. micpohling.wordpress.com
or 5.1480xe18 kg. 1 ton is 907.185 Kilograms
5.1480xe18 kg / 907.185 .0056783 xe18 tons or 5.6783 xe15 tons or 5.6783 millon gigatons
molar mass of air is 28.97 g/mole
molar mass of CO2 is 44.0095 g/mole
ppm of CO2 represent a percent of the atmosphere.
400 ppm is .04% thus the mass percent of CO2 by mass is 44.0095/28.97 * .04 or .06076%
Total weight of CO2 is ,0006076 * 5.6783xe15 tons. or ,00345 xe15 tons or 3.45xe12 tons 3450 gigatons
14177/3450
1997/98 El Niño events, water vapor amounts and thus total mass increased by about 0.1 hPa in surface pressure or 0.5 × 1015 kg for several months.
journals.ametsoc.org
dry air mass as 5.1352 ± 0.0003 × 1018 kg of atmosphere
The total mean mass of the atmosphere is 5.1480 × 1018 kg
The mean mass of water vapor is estimated as 1.27 × 1016 kg
