Notes on the dynasonde soundings on this disk (CD-TR002)

The data are from the Tromso dynasonde.

The soundings are stored in directories according to the month of recording.
In some cases the soundings for a month are spread over more than one directory
as in OCT1993a and OCT1993b. 
In this particular case the split marks a major change in antenna configuration
to "Owen Jone's L-POL" and the corresponding sounding numbers jump to TR300001.*  

In the listings of soundings (files with extension .DIR) the dates and
times were read from the soundings and should be as accurate as the 
dynasonde PC clock at the time of data taking. A few files which show a
date as 19700101 have a corrupted time/date.

The soundings are listed according to type in files B-MODES.DIR, I-MODES.DIR,
K-MODES.DIR, P-MODES.DIR, as well as a total listing in LIST-ALL.DIR

The CALIBS.DIR shows where calibration soundings (with file extension *.?r?)
are stored.

The GAPS-x.TXT files show missing soundings (or repeated sounding numbers)
for the four various modes of sounding (b,i,k,p).
