Dynasonde diary

1992

• Between 8-22 Nov 1992 the Dynasonde Interdata computer was replaced by a 486 33 MHz PC with 400MB hard disk. The new operating environment FAIS together with the CRAM card and two SKY DSP boards was installed with help from Tom Berkey. Initial antenna configuration was 4-ant X-wherpol.
  Some experiments were made with Dynasonde and Heater.

  The first soundings have some errors in the header information. In particular, TR000001.B_G 19921112 15:54:00-15:55:43 to TR000240.B_G 19931115 20:45:00-20:46:43 have the antenna configuration information as shown in this table:
  Array Orientation: 0.40

Rx	Mux	X	Y	Z	orient
1	1	0.0	0.0	5.0	0.1
1	2	10.1	1.2	5.1	0.5
2	1	0.0	0.0	4.9	89.5
2	2	0.1	11.3	2.3	90.2

which is wrong. The soundings TR000241.B_G 19921115 23:25:00-23:26:43 to 5 Feb 1993 are slightly better but still wrong:

Array Orientation: 0.40

Rx	Mux	X	Y	Z	orient
1	1	0.0	70.7	2.0	0.1
1	2	70.7	0.0	2.0	90.0
2	1	0.0	1.5	0.0	0.0
2	2	0.0	1.9	90.0	0.0

After 5 Feb 1993 there is again an improvement but still wrong !:
Array Orientation: 16.5

Rx	Mux	X	Y	Z	orient
1	1	0.0	70.7	2.0	0
1	2	70.7	0.0	2.0	90
1	3	23.7	0	0.0	90
2	1	0.0	1.9	0	0
2	2	0.0	1.5	90	0
2	3	0	0	0	0

The mistakes were corrected on 15 Aug 1993. All the above should be replaced by:
Array Orientation: 16.5

Rx	Mux	X	Y	Z	orient
1	1	0.0	70.7	2.0	0
1	2	70.7	0.0	2.0	90
1	3	23.7	0	0.0	90
2	1	0.0	-70.7	1.9	0
2	2	-70.7	0.0	1.5	90
2	3	0	-23.7	0.0	0

  The year is wrong from TR000236.B_G 19931115 18:55:00-18:56:43 to TR000240.B_G 19931115 20:45:00-20:46:43 (subtract 1 year)
