Manually corrected error in header files
DataStreams:sgpmwrlosB1.a0, sgpmwrlosB1.a1, sgpmwrlosB5.a0, sgpmwrlosB5.a1, sgpmwrtipB5.a0
Description:
On 10/27/97 at 20:00 UTC, an error was made while remotely editing the
MWR configuration file.
This produced an error in the data file header which made the normal
processing programs fail. The problem was identified on 11/10/97.
The configuration file at BF1 was corrected on 11/11/97 at 19:40.
MWR.BBF5 wasremoved from service on
11/5/97 17:54. The configuration file at BF5 was corrected prior to 
reinstalling the MWR on 1/9/98.

The file headers of these data were reconstructed and the
data were delivered to the Archive on 11/26/97 for MWR.BF1
and on 12/3/97 for MWR.BF5.

This DQR is being filed to note that the headers were manually
recreated. The data should be unaffected.

This DQR is based on information obtained from Victor Morris
and Robin Perez.

SGP/MWR/B5 - Reprocess: Calibration update
DataStreams:sgpmwrlosB5.a0, sgpmwrlosB5.a1, sgpmwrtipB5.a0
Description:
With the MWR at Morris, there appears to be a very large (~0.5mm) positive bias in the LWP 
and the PWV values are much larger (~4cm) than reported by the soundings. Recent repairs 
by the manufacturer appear to have significantly changed the calibration.

The tip data acquired during the SCM IOP on 29-30 January at Morris have been reduced. It 
was updated at 17:00 on 9 February. The calibration will be closely monitored to 
determine if the previouly-reported (P971104.1) drift in the 31.4 GHz channel has been corrected.

The table below compares the latest calibration with previous ones.

SGP/MWR/B5 - Incorrect serial number

Description:
The MWR serial number was changed from 012 to 001 in the configuration file while the 
instrument was off line for repairs and testing. This resulted in an incorrect serial number 
used in the filename extension of the raw data file and placed in the header of the cdf 
file. Data quality were not affected.

SGP/MWR/B5 - Software Change
DataStreams:sgpmwrlosB5.a1
Description:
The MWR operating software was changed on 12 February 1998 to provide additional 
functionality as described below. This change affects the format of the raw and ingested data. 
   
NEW FEATURES
1. Faster sampling rate
   
Standard line-of-sight (LOS) observations can now be acquired at 15-second intervals vs. 
20-second intervals previously. (The standard LOS cycle is comprised of one sky sample per 
blackbody sample and gain update.)
   
2. More flexible sampling strategy
   
Multiple sky observations can be acquired during a LOS cycle, up to 1024 per gain update. 
This permits sky samples to be acquired at intervals of 2.67 seconds for improved 
temporal resolution of cloud liquid water variations and better coordination with the millimeter 
cloud radar during IOPs.
   
3. Separation of zenith LOS observations from TIP data
   
When the radiometer is in TIP mode, the zenith LOS observations are now extracted, the PWV 
and LWP computed and reported separately in the output file. This eliminates the periods 
of missing LOS data during calibration checks/updates.
   
4. Automatic self-calibration
   
The software now permits the calibration to be updated at specified intervals or 
continuously. In the first case, LOS mode is automatically changed to TIP mode at user-specified 
intervals or whenever clear sky conditions occur, the tip data reduced, the calibration 
updated, and the radiometer returned to LOS mode without operator intervention. In the 
second case, the radiometer is continuously is TIP mode until changed by the operator.
   
5. Graphical user display
   
The graphical display is comprised of a status display, a message display, a temperature 
plot, a plot of the retrieved PWV and LWP, and (in TIP mode) a plot of the latest tip 
curves.

SGP/MWR/B1/B4/B5/B6/C1 - software upgrade (version 3.27)
DataStreams:sgpmwrlosB1.a1, sgpmwrlosB4.a1, sgpmwrlosB5.a1, sgpmwrlosB6.a1, sgpmwrlosC1.a1,
sgpmwrlosC1.b1, sgpmwrtipB1.a0, sgpmwrtipB4.a0, sgpmwrtipB5.a0, sgpmwrtipB6.a0
Description:
At 00:00 GMT on 7 January version 3.27 of the MWR operating program was installed and made 
operational at the SGP central facility (C1).  No problems were noted over the next few 
days and the boundary facility MWRs (B1, B4, B5, B6) were upgraded at 20:00 GMT on 11 
January.  This version includes a beam width correction I developed as well as providing the 
capability to automatically level the elevation mirror (that is, to automatically detect 
and correct offsets in the elevation angle stepper motor position.)

On 12 January I discovered that the '486-based MWR computers at B1, B4 and B6 were not 
executing the system command to move and rename the data files so that the ARM data system 
could retrieve them.  Reducing the length of the storage arrays in the auto-leveling 
feature from 1000 to 250 resolved the problem.  This results in the auto-leveling being based 
on only 4 hours of clear sky data rather than 16 hours at B5 and C1.  This version of the 
program is 3.28. Version 3.27 (running at B5 and C1) can be installed if and when these 
computers are upgraded to Pentium-class machines.

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.  The goodness-of-fit coefficient for 
the tip curves has improved from about 0.995 to over 0.998.  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.

Editor's Note: The SGP.C1 data were reprocessed in 2004 to produce a common DOD for all 
time.  The 1996-1998 data reprocessing included beam width and mirror-leveling corrections, 
but the data prior to that range did not have these corrections applied.

Description:
The MWR was returned to the manufacturer for repair and upgrade.
Radiometric's service report follows:

Here are the repairs/modifications that were performed on
WVR12.

Found dew blower heater IC driver and AC relay failed.
Replaced both.
Replaced dew blower fan because of aging.

Updated R4 (2.4K), R9 (100 ohm) on digital board; makes
elevation motor sensor less sensitive to sunlight when
cover is off.

Installed 0.1 mfd caps on power supply 7840 voltage
regulators, pin 8 to 11. Makes PS more stable
  Set PS voltages 5.1 and 12.5 volts Set PS current limits
  with dummy load.

Installed 0.01 mfd to gnd,, 0.1 mfd across pins 1&2 on
AD524. RFI mitigation.

Installed ferrite chokes on +/- 15 volts at IF/video amp.
RFI mitigation.

Replaced cracked crossguide coupler. Undoubtedly the cause
of noise diode shifts.

Replaced INMET 3016 50 ohm load on IF port with 3016A

pseudo-noise figures: 23GHz= 5.19: 31GHz= 5.26 Temp. coefs.
23GHz -0.01: 31GHz 0.03.

Data collected during this period should be ignored as they 
are due to testing by the manufacturer and are unrepresentative
