What is the relation between those ?
More grain of water per pound of dry air mean less air molecule in that pound of dry air.
I know that some area own more % oxygen than other (degree of pollution, tree, altitude, near ocean...) But do they serve the same goal in weather calculation or they have their own impact on calculation.

Charles,
If you want to learn all about weather correction, get Patrick Hale's book, "Motorsports Standard Atmosphere and Weather Correction Methods".

The book is considered the best on its subject.

Also, for software, I recommend Performance Trends "Weather Wiz".
Extremely accurate, as long as data inputs are good.
