TWP/VCEIL/C1 - Ceilometer offset
DataStreams:twpvceil25kC1.b1
Description:
When the replacement ceilometer was installed at Manus it was tilted 6 degrees.
Since the angle correction setting was not activated, the cloud base heights
reported by the instrument were higher than actual by 0.55% (39 m at 7 km).
Measurements:twpvceil25kC1.b1:
  • Third cloud base height(third_cbh)
  • Lowest cloud base height detected.(first_cbh)

TWP/VCEIL/C1 - Ceilometer clock drift
DataStreams:twpvceil25kC1.00, twpvceil25kC1.a1, twpvceil25kC1.b1
Description:
During this period the ceilometer was using a software version that
provided time stamps that were based on the ceilometer clock and
not the computer clock that was continually sychronized with GPS.
This lead to times that were erroneous by as much as 2 minutes. For
most applications 2 minutes is an acceptable error, but for some
applications this may be a problem.

Description:
On November 18 the generator was turned off due to a fault in the oil
pressure sensor. It had been having trouble for at least a day prior
to the manual shut-down. ADaM, the MPL, and the WSI were also shut
down to prevent an unscheduled power cycle. As a result, there is a block 
of missing data from November 20-27 for all of the instruments except 
those connected to the Zeno loggers (SKYRAD, GNDRAD, SMET).

TWP/VCEIL/C1 - Degraded Ceilometer Window
DataStreams:twpvceil25kC1.a1, twpvceil25kC1.b1
Description:
Data from the ceilometer during this period is suspect. From 10/28
until about 2/4 the instrument had a deteriorated window.  This
caused the ceilometer to only be able to see cloud heights up to
about 2 km.
Measurements:twpvceil25kC1.a1:
  • Third cloud base height(third_cbh)
  • Aerosol volume backscattering coefficient at 355 nm(backscatter)
  • Lowest cloud base height detected.(first_cbh)

TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpmplC1.a1, twpmwrlosC1.a1, twpmwrlosC1.b1, twpvceil25kC1.a1, twpvceil25kC1.b1
Description:
Bill Clements reports we have been using 6m MSL as the station elevation of Momote 
(Manus).  This was based on information posted near the station barometer in the Momote Weather 
Service Office.  It turns out that the official WMO station elevation for Momote is 4m 
MSL and the upper air elevation is 5m MSL.

All Manus instruments except the sonde station are at 4m MSL. The sonde launching station 
is at 5m MSL.

TWP/VCEIL/C1 - Data dropouts
DataStreams:twpvceil25kC1.00, twpvceil25kC1.b1
Description:
The Manus ceilometer was not receiving complete data packs from the ceilometer. This 
occurred at irregular intervals up to 3-10 times per hour until an error occurred and the 
computer locked up.  The data were not affected when they were successfully collected.  Days 
on which the data are missing for more than 1 hour are listed below.  Some maintenance 
was done on the ceilometer data computer in November and the computer was ultimately 
replace on 3 January 2005.
