TWP/MPL/C1 - Extended data gap
DataStreams:twpmplC1.a1
Description:
The lidar was taken off line because of problems with the site back-up
power generator.  The power issues have been resolved but the MPL
experienced an apparent computer problem and could not be started
remotely.  We have approximately 1 hour of data from December 11
(00-01 GMT). The RESET team visited Manus in February and got the
MPL going again on the 16th of that month.
Measurements:twpmplC1.a1:
  • Voltage level which operates the A_D card and the detector(voltage_5)
  • Laser temperature(laser_temp)
  • Voltage level which operates the thermistor(voltage_10)
  • Average cloud base height used in the retrieval(cbh)
  • Aerosol volume backscattering coefficient at 355 nm(backscatter)
  • Number of laser pulses summed during measurement interval(shots_summed)
  • Background signal(background_signal)

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/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/MPL/C1 - SunShade timing problem
DataStreams:twpmplC1.00, twpmplC1.a1, twpmplcmask1clothC1.c1, twpmplsmask1clothC1.c1
Description:
For an unknown reason, the sun shade was dropping for less then 10 minutes during the 
night at about 19:00 UTC between Dec 14, 2003 and Feb 17, 2004.  Data taken during that ten 
minute interval is not looking at the sky and should be considered as though it were 
missing.

This is a fairly small effect.  Data users can simply average across the interval or block 
the records as "missing".
