TWP/VCEIL/C2 - Installation
DataStreams:twpvceil25kC2.00, twpvceil25kC2.a1, twpvceil25kC2.b1
Description:
The Nauru ARCS was installed during the period September-November
1998.  Data were being collected by the end of October, but for the
first several weeks of November, the site was undergoing considerable
change, so data from that period should be used with caution.  The
official site dedication occured on November 20.  Most on-site
activity ended following the dedication so we will consider November
20 to be the beginning of the Nauru operations.  The last members of
the installation team left Nauru on November 24.

TWP/VCEIL/C2 - Ceilometer failure
DataStreams:twpvceil25kC2.00, twpvceil25kC2.b1
Description:
Large data gaps began occurring frequently at the TWP Nauru site 26 February at 06Z.  
Prior to 25 February, optical cross talk errors had been observed.  Beginning on 25 February, 
data errors were observed.  By 26 February, these errors were exhibiting themselves as 
extended data gaps.  These gaps became increasingly frequent between 2/26 and 3/4.  All 
data are missing after 20050304.1550.

The instrument was replaced on 29 March and after some subsequent configuration work, the 
instrument was revived just after 00Z on 1 April.

TWP/VCEIL/C2 - occasional communication fault
DataStreams:twpvceil25kC2.b1
Description:
Beginning August 30, 2005, the Nauru Ceilometer periodically went into a strange 
operational mode where the backscatter data exhibits vertical stripes.  Looking at the backscatter 
data - there are high amplitude oscillations occuring in the backscatter as a function 
of time at a given height.  The phenomenon appears to be more common at night.  Dates 
include: 30 Aug, 31 Aug, 1 Sep, 9 Sep, 15 Sep, 20 Oct, 22 Oct, 8 Dec, and others.

The fiber optic link to the ceilometer was faulty and causing periodic data corruption. 
The problem was corrected when the fiber optic line was replaced with a hard wired RS232 
link.

TWP/VCEIL/C2 - Time offset
DataStreams:twpvceil25kC2.b1
Description:
On 7/14/2006, I found that the ceilometer time was 8m 36s slow, the PC time display (lower 
right taskbar) was frozen at "22:24", and AboutTime was not running. Corrected it on 
7/17 by running AboutTime so that 19:03:29 became 19:12:05. This also corrected the frozen 
display on the Windows98 taskbar. 

I am not sure of the start time of this problem but there were several other Windows 
related issues that had to be corrected on 5/14 with indications of inappropriate access via 
Remote Administrator on 5/13. I do not know if the time offset was a sudden or gradual 
change.

Attribute serial_number: In most cases, this field is not representative of the actual

TWP/VCEIL/C2 - Reprocess: wrong serial number
DataStreams:twpvceil25kC2.a1, twpvceil25kC2.b1
Description:
The instrument was replaced with a spare with an incorrect unit ID, that determines the 
serial number assigned by the ingest.

The data can be reprocessed to replace the unit_id of "m" with "j", or to replace the 
attribute serial_number of "V45106" with "U06301".
Measurements:twpvceil25kC2.b1:
