16 | Example of FFI 1001 (b). |
---|
17 | This example illustrating NASA Ames file format index 1001 is based on the US Standard |
---|
18 | Atmosphere 1976 as quoted in G. Brasseur and S. Solomon, Aeronomy of the Middle |
---|
19 | Atmosphere, Reidel, 1984 (p. 46). It provides typical values of middle latitude averaged air |
---|
20 | concentration and temperature as a function of height (expressed here as the altitude |
---|
21 | above sea level). The first date on line 7 (1st of January 1976) is fictitious since the |
---|
22 | parameters are yearly averages. We have inserted 1 additional line into the original table |
---|
23 | (at 125 km altitude), to illustrate the use of the "missing value" flags (see line 12). |
