I figured it out... thanks for your help. [link to personal website removed]

universal gas constant = 8314.32 (in 1976 Standard Atmosphere) molecular weight of dry air = 28.964 8.3143 / 28.964 = 0.28705634580859 (e.g., 287.056)

I am not a physicist... so you are implying that the differences in the values is insignificant? To me, it should be exact... or a means should be in place to get the exact value at each given location of sampling... if this was indeed possible, which it may not be. Please advise.

I'm confused on why the dry air gas constant varies: Dry Air Gas Constant of 286.9 from The Engineering Toolbox Dry Air Gas Constant of 287.22 from https://www.physicsforums.com/ttp://www.peacesoftware.de/einigewerte/luft_e.html Dry Air Gas Constant of 287.05 from Brisbane Hot Air Ballooning...
