This example illustrating NASA Ames file format index 2010 is based on results from Murgatroyd (1969) as displayed in Brasseur and Solomon, Aeronomy of the Middle Atmosphere, Reidel, 1984 (p.36). It is representative of the mean zonal wind distribution in the winter hemisphere as a function of latitude and height. The first date on line 7 (1st of January 1969) is fictitious. From line 10 (NXDEF = 1) we know that the latitude points are defined by X(i) = X(1) + (i-1)DX1 for i = 1, ..., NX with X(1) = 0 deg (line 11), DX1 = 10 deg (line 8) and NX = 9 (line 9). 11 The files included in this data set illustrate each of the 9 NASA Ames file format indices (FFI).
