Standard Atmosphere, SI Units D.1 NOTE ABOUT THE STANDARD ATMOSPHERE TABLES IN APPENDICES D AND E The following Standard Atmosphere Tables are compiled from mean experimental data for the temperature variation with altitude, combined with the laws of physics to compute the corresponding variation of pressure and density. The laws of physics used are the hydrostatic equation (Equation 1.52) and the equation of state (Equation 7.1). The construction of the Standard Atmosphere Tables is discussed in detail in Chapter 3 of Reference 2, which you should read to learn the whole story. In Appendices D and E, the temperature, pressure and density are tabulated versus altitude. Two columns for altitude are given, the first for the geometric altitude h G , and the second for the geopotential altitude, h. The geometric altitude is the actual height above standard sea level, and the geopotential altitude is a related altitude based on the assumption of a constant value of the acceleration of gravity used for the calculations. See Reference 2 for an explanation of the difference. In this book, whenever a reference is made to a certain value of the standard altitude, it means the value of h G , the first column in the tables. Appendix D gives the Standard Atmosphere in SI units, and Appendix E gives the Standard Atmosphere in English Engineering units. There exist tables of the standard atmosphere compiled by various organizations over the years. The values tabulated in Appendices D and E are taken from the 1959 ARDC model atmosphere compiled by the U.S. Air Force.
