Air properties at high altitudes 1

[HTransfer]

I would like to get air properties such as dynimic viscosity, specific heat, thermal conductivity as well as density at high altitudes. Will you suggest any text, calculator or any other information in which I can obtain those properties at various altitudes?

wouldn't it be possible to use a standard composition of air in a process simulation environment (aspen, simsci, whatever)and to calculate the properties at conditions below 1.013 bar abs, i.e. vary the pressure?

Isn't that pretty much dictated by the pressure and temperature at altitude?

Anyway, there are some links that might do most of what you want:

Thank you for all of your help.

Especially, the links are very useful.
