This file format, described at https://www.aoml.noaa.gov/phod/dhos/axbt.php, contains a header
line, followed by data lines. For example, a particular file at this site has first
three lines as follows.
181.589 20100709 140820 -85.336 25.290 N42RF GL10 14 2010-190-15:49:18 -0.0 27.52 -9.99 -1.5 27.52 -9.99
where the items on the header line are (1) a year-day (ignored here), (2)
YYYYMMDD, (3) HHMMSS, (4) longitude, (5) latitude, (6) aircraft wing
number, (7) project name, (8) AXBT channel and (9) AXBT ID. The other lines hold vertical
coordinate in metres, temperature and temperature error; -9.99 is a missing-value
code. (This formatting information is extracted from a file named readme.axbt that
is provided with the data.)
