24Example of FFI 4010.
25This example illustrating NASA Ames file format index 4010 is entirely fictitious.
26Data have been made up for the purpose of illustrating the use of the format. They
27consist in an imaginary calculated temperature distribution over a longitude-lati-
28tude-altitude grid at 6 o'clock and noon on the 21st of June 1980. The grid is
29defined in lines 8, 9, 11, 12 and 13. Longitude ranges from 30 degrees West to 30
30degrees East by intervals of 5 degrees. Latitude ranges from 90 North to 90 South by
31negative intervals of 30 degrees. Altitude takes the two values of 20 and 50 km.
32If the temperature is written as T(lon, lat, alt, time), the record below thus reads,
33for each of the two times t = 6 and t = 12,

45indices (FFI). A detailed description of the NASA Ames format can be found on the Web
