Notes on the dynasonde soundings on this disk (CD-TR063)

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



The latest versions (from FAIS10b CD) of datmovie, echoplot, 
datbrows, and dataplot are in the file datmovie.zip
----------------------------------------------------------

General notes:
==============
The data are from the Tromso dynasonde.

Sounding raw data
=================

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).

IDI data
========
The results from  the IDI ("Imaging Doppler Interferometry") 
soundings are included. Since 2 May 1999, this mode has been 
running between interspersed between the B-mode soundings. 
The original P-mode soundings on which they are based are not 
recorded, nor are the P-mode sounding numbers incremented.
The results, together with some analysis/potting IDL scripts
are in the directory IDI_RSLT. A byproduct of these soundings
are possible meteor echoes. They are recoded in the directory
METEORS together with some IDL plotting scripts.
The software running in Tromso is an implementation of
that written by Owen Jones of BAS for use at Halley Bay.
Information on the IDI technique is found in notes in the
file idi_note.wpd.

In brief: the yyyymmdd.ivb file is the day's results in
binary file format. The yymmddbn.zip files contain the
individual day's "parameter files" in binary format.
There are some IDL scripts which can handle these data.
