TWP/MWR/C2 - Uncertainty in clock time
DataStreams:twpmwrlosC2.b1, twpmwrtipC2.a1
Description:
At ARCS2, the MWR computer clock was not being updated because no NTP time service 
software was installed on the computer. During Nauru99, on 6/24/99, the clock was found to be 3 
minutes and 17 seconds fast. 

Assuming that the time was properly set at installation on 10/26/98 (which is not 
indicated in the installation report) and never reset until 6/24/99, the rate of time drift on 
the computer was about +0.8 seconds per day. However, if the time was not reset since 
integration at AIS on 1/14/98 (which is recorded in my integration notes), then the rate of 
drift is about +0.4 seconds per day.

The computer was replaced and time service started on 7/30/99.

TWP/MPL/C2 - Power Oscillation
DataStreams:twpmplC2.a1
Description:
There is an oscillation that shows up in the reflected power and the power monitor.  This 
oscillation shows up clearly whenever there is an absence of low (< ~5 km) clouds. Cloud 
return signals tend to be much larger than the level of this oscillation; however, it may 
introduce problems for studying aerosol distributions.  The end date of this DQR is 
artificial in that this is as far as the QC went.

TWP/MPL/C2 - Nauru MPL Laser Diode accidentally off
DataStreams:twpmplC2.a1
Description:
The emission from the laser diode supply was accidentally off.  The Instrument
Mentor, Connor Flynn, called Nauru directly and had them turn the laser emission
back on.  Backscatter and cloud base data during the period between 
2000-11-11 00:00 GMT and 2000-11-13 22:00 GMT should be regarded as bad 
or incorrect while background light data and local temperature values are 
acceptable.

TWP/MWR/C2 - Excessive wet_window flags
DataStreams:twpmwrlosC2.b1, twpmwrtipC2.a1
Description:
The wet_window flag is set high more than expected from the measured value of liquid water 
path. This may be caused by dew or, if the heater sensivity is slightly misadjusted, by 
the diurnal variation in ambient temperature.

The "wet_window" flag is an indicator of moisture on the MWR window which invalidates the 
measurements of precipitable water vapor and liquid water path. Sometimes this flag can 
be incorrectly set high or low if the heater sensivity is slightly misadjusted. The heater 
adjustment is a resistive device that is dependent on ambient temperature. Another 
indicator of moisture on the window is unreasonably high ( > 3*liquid_retrieval_rms_accuracy ) 
values of "liq".

TWP/MWR/C2 - software upgrade (version 3.29)
DataStreams:twpmwrlosC2.b1
Description:
The MWR operating program was upgraded to version 3.29 on 30 July 1999. This version 
included a beam width correction as well as provided the capability to automatically level the 
elevation mirror (that is, to automatically detect and correct offsets in the elevation 
angle stepper motor position.)
   
The improvement in the quality of the tip curves resulting from the auto-leveling has been 
dramatic: differences in the brightness temperatures at 3 airmasses (19.5 and 160.5 
degrees) have been reduced from +/- 5 K to +/- 0.5 K. In order to take full advantage of this 
improvement to detect and reject cloudy tip curves, the minimum value of the 
goodness-of-fit coefficient for a valid tip curve has been increased from 0.995 to 0.998.

The data prior to July 30 1999 do not include beam-width and mirror-leveling corrections.
