Subject:
AWR/LDIS/MET/S1 - Precipitation Measurements Suspect
DataStreams:awrmetS1.b1
Description:
Analysis of the PARS2 and the PWD precipitation data indicate that the results are 
suspect, possibly due to frost/blowing snow.  Both instruments reported precipitation for a 
majority of the days.

The TSI movies were reviewed and the days of noticeable precipitation are:

12/26/15
12/31/15 - Potentially just frost buildup
1/6/16
1/11/16
1/12/16
1/13/16
Measurements:awrmetS1.b1:
  • PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min)
  • pwd_cumul_snow
  • pwd_pw_code_15min
  • pwd_cumul_rain
  • PWD 1 minute mean visibility(pwd_mean_vis_1min)

AWR/TSI/S1 - Reprocessed and Corrected: Sky filter thresholds
DataStreams:awrtsicldmaskS1.a1, awrtsiskycoverS1.b1
Description:
DATA REPROCESSED and CORRECTED: 


The data were reprocessed after changing the sky filter thresholds from clear/thin = 50 
and thin/opaque= 70 to 40 and 60, respectively.

The data were archived November 2016. Please retrieve the reprocessed data for use in your 
analysis.

Subject:
AWR/CEIL/S1 - Reprocess: Incorrect averaging_inverval global attribute
DataStreams:awrceilS1.b1
Description:
When the ceilometer software was changed from CT-View to CL-View, several firmware 
configuration changes were made to the model CT25K for consistency with the CL31 at other sites, 
including the data acquisition interval which was changed from 15 to 16 seconds. 
However, the global attribute "averaging_interval" in the ceil datastream was not changed.

Description:
The global attribute cam_mir_dist was converted incorrectly. The raw 
camera.mirror.distance, in inches, was multiplied by 10 and assigned a unit of mm.
