Example of FFI 1020 (a).
This example illustrating NASA Ames file format index 1020 combines the US Standard
Atmosphere 1976 (for the auxiliary variables Pressure and Air Concentration) and some
results of a 1-D model (for the dependent variables - oxygen compounds concentrations),
as quoted in G. Brasseur and S. Solomon, Aeronomy of the Middle Atmosphere, Reidel,
1984 (pp. 46 & 211). The first date on line 7 (1st of January 1976) is fictitious since
the parameters are yearly averages. We have signalled the absence of calculated values at
30 and 105 km by using the "missing value" flags (see line 13). The missing value flag
is also used to give account for the fact that there is virtually no O(1D) present below
the altitude of 20 km. Note that the data are identical as the data contained in the
example illustrating FFI 1010, but in a more compact format.
