Notes on the dynasonde soundings on this disk (CD-TR033)

Notes specific to this disk:
============================

In February 1999 there was a Heating campaign.
Especially 15-21 Feb 1999. Artificial airglow !

The directory Feb1999b (15-28 Feb 1999) should have been 
recorded on CD-TR032 but was inadvertently omitted. The
listings on CD-TR032 show the files even they they were not 
recorded.

General notes:
==============

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
e.g. DEC1994a and DEC1994B. 

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

Note that P-mode soundings that raw data soundings of type I- or
B-mode, although also "P-mode" are usually named *.IPG or *.BPG
and are numbered and catalogued as I or B-mode. 

The CALIBS.DIR shows where calibration soundings (with file extension 
NOT *.?_? , usually of type *.?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).
