Hello,

I have average ozone mixing ratio data (ppbv) from interval levels in the troposphere (0-250m / 250-500 / 500-750 . 11500-11750)  covering a 4 degree by 4 degree area of land (surface area = 164,660,000,000 m^2).

I would like to calculate the weight of Ozone in Kg from each altitude interval.  I have supplementary data including temperature (k) and pressure (Pa) which i have also created averages and top and bottom bounds for each altitude interval.

Does anyone know where is can start with this?

so far i have been using the following formulae provided by an anonomous source;

first I calculate Sm (no idea what sm is!) = surface area of my grid (in m^2) * (pres @ bottom altitude interval, in Pa) - (pres @ top altitude interval, in Pa)/g

g= 9.81 m/s^2


Burden of Ozone in the grid box:

burden (in kg) = (ozone average in pbbv * 1.e-9) * (48./28.9) * sm


1.e-9 is a constant; 48.21 is the molecular mass of ozone; and 28.9 is the molecular mass of dry air

here is an example of my data

Surface Area    Ozone (ppbv)    press (Pa) @ the Bot of box     press (Pa) @ the top of box     
164660000000  46.669             99012                                  97836

from this data for a theoretical box with an altitude of 0-250m and surface area of164660000000 I calculated a weight of 26983246974 Kg of Ozone which just sounds way to high to me!

If you have any information of criticisms with my calculation or simply a new or better way to calculate ozone weight within a column please let me know
