Example of FFI 1001 (a).
This example illustrating NASA Ames file format index 1001 is based on the US Standard
Atmosphere 1976 as quoted in G. Brasseur and S. Solomon, Aeronomy of the Middle
Atmosphere, Reidel, 1984 (p. 46). It provides typical values of middle latitude averaged air
concentration and temperature as a function of height (expressed here as the pressure
level). The first date on line 7 (1st of January 1976) is fictitious since the parameters are
yearly averages. We have inserted 3 additional lines into the original table near the tropo-
pause and stratopause levels, to illustrate the use of the "missing value" flags (see line 12).
