GRW/MWR/M1 - Loose mirror
DataStreams:grwmwrlosM1.b1, grwmwrtipM1.a1
Description:
The data from the MWR were suspicious and became progressively worse. The problem was 
traced back to the fact that the screw that keeps the mirror in place had become loose and 
the mirror was freely rotating. 

The mirror was tightened on 6/9/2009, however the measurements were noisy until 6/16, when 
the instrument was rebooted and all the connections checked. 

Measurements between 5/1 and 6/9 should not be used. Data between 6/9 and 6/16 are usable, 
although they are very noisy.

GRW/SONDE/M1 - Wind data missing
DataStreams:grwsondewnpnM1.b1
Description:
A GPS problem associated with Vaisala BBSS ground station software issues caused the 
ground stations to enter into an error state when using GPS wind finding. In some instances, 
the flight was aborted due to the error state and no data was collected.  A workaround was 
developed to allow sondes to be launched without collecting wind data.

Counter, failed. A new TEC was mailed to GRW. The TEC was replaced and the CPC was working 
again on Jan. 15th, 2010.

GRW/WACR/M1 - Interference/False signal
DataStreams:grwwacrM1.b1, grwwacrspeccmaskcopolM1.a0, grwwacrspeccmaskxpolM1.a0
Description:
Interference occurred between the WACR/SWACR beginning 9:45 GMT on 09/25.  This effect was 
not as noticeable on DQ plots until ~10 GMT on 09/27 at which time the interference was 
quite pronounced as vertical bands in the reflectivity and velocity plots.  The 
interference was slightly noticeable in the spectral width plots as well.  

Interference resulted from the SWACR using the same frequency as the WACR.  Interference 
was alleviated by changing the pulse repetition frequency (prf) from 10 kHz to 9.9 kHz.  
Some minor contamination still existed during the presence of highly reflective 
clouds/precipitation.

The Doppler velocity was not affected as much by the interference.  A cloud mask based on 
the Doppler velocity will remove most of this contamination in the reflectivity and 
spectra width measurements.

GRW/MWR/M1 - Incorrect ambient temperature
DataStreams:grwmwrlosM1.b1, grwmwrtipM1.a1
Description:
The ambient temperature readings are incorrect.  Problem appeared to have started around 
10:48 GMT on 02/09, but was not really noticeable until slightly after 11 GMT, when tkair 
values dipped considerably.  

The dewblower was replaced on 2/11 and temperature readings returned to normal.

GRW/WACR/M1 - Coherence Filter Contamination
DataStreams:grwwacrM1.b1
Description:
The coherence filter (software) that was added to the WACR under BCR-01500 was causing 
occasional contamination to WACR data.  This was exhibited in the first 2000 m of range by 
streaking in the data over a period of time. It didn't occur often and when it did, it is 
quite obvious looking at the plots.  

On 4/2/2010 at 12:00 UTC, the coherence filter was modified to preclude working on signals 
with a SNR greater than 60 dB.  The vendor thinks this will solve the problem.

GRW/AOS/M1 - CCN Detector misalignment
DataStreams:grwaosccnM1.a1
Description:
The CCN signal was unusually low about 100 particles/cc. The %SS growth curves were 
asymmetrical. Upon consultation with the manufacturer, DMT, it was predicted that the OPC 
detector was clogged or misaligned. I had the tech, Carlos, remove the detector and ship it 
back to Boulder. The detector was cleaned. An o-ring for a lens wasn't properly seated. The 
OPC was sent back to GRW and installed. Data looks normal after the reinstallation on 
July 13th.
Measurements:grwaosccnM1.a1:
  • AOS number concentration of CCN(N_CCN)
  • AOS CCN number concentration by bin(N_CCN_dN)
  • AOS bin number of lowest channel of OPC include in summation of N_CCN(N_CCN_bin_number)

GRW/MWR/M1 - Incorrect instrument computer set-up
DataStreams:grwmwrtipM1.a1, grwmwrlosM1.b1
Description:
Starting late on 07/11 the instrument began to have very brief (< 1 min) data outages 
every few hours.  By 07/12 data had become noticeably incorrect, particularly the PWV, LWP, 
TB23, and TB31.  At ~17 Z on 0713 the missing data / no data available flags became more 
frequent.

The problem was identified as improper settings of the instrument computer and was solved 
on 8/9.

GRW/MWR/M1 - Erratic brightness temperature
DataStreams:grwmwrlosM1.b1, grwmwrtipM1.a1
Description:
Around 12 Z on 7/20 both the PWV and 23.8 GHz brightness temp values began to diverge from 
those of the MWRP. By 7/22 both the LWP and 31.4 GHz brightness temp had followed suit. 
At 0600 Z on 7/22 multiple (10-20), brief (<=1 min) data outages began appearing hourly.  
The problem persisted intermittently until 8/9.

On 8/9, changes in the settings of the computer restored the proper functionality of the 
MWR software.

GRW/AOS/M1 - Data processing problem
DataStreams:grwaosM1.a1, grwnoaaaosM1.b1, grwnoaaaosavgM1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.

GRW/AOS/M1 - CCN signal decline
DataStreams:grwaosccnM1.a1
Description:
There was a slow decline in the CCN signal from January to June of 2010 at GRW. The reason 
for this decline is unknown as all the instrument operating parameters appear normal. 
The decline was likely from a change in the CCN column thermal properties or a clogging of 
the detector inlet.
