Subject:
TWP/SMET/C1 - Reprocess: ORG Data has very small rainrate values
DataStreams:twpsmet60sC1.b1
Description:
The ORG data is collected via analog signal and not digital.  Therefore, we continuously 
collect data even when no rain is occurring.  We also capture small events such as leaves, 
large bugs, dust, etc blowing through the measurement path.  Because this discrete event 
occurs quickly the value is usually captured for 1 or 2 seconds.  This value is then 
averaged to the minute producing rainrate on the order of .009 mm/hr or less.  These values 
are not indicative of rain and should be removed from the record or summing over long 
periods can bias the climate record.  We are reprocessing the data to remove these small 
values and are adjusting the collection program to remove them before ingest.
Measurements:twpsmet60sC1.b1:
  • Precipitation minimum(precip_min)
  • Precipitation maximum(precip_max)
  • precip_sd
  • Precipitation mean(precip_mean)

Subject:
TWP/SMET/C1 - Missing RH, Barometer, and ORG data
DataStreams:twpsmet60sC1.b1
Description:
Atmos_pressure data suddenly went missing on 03/02 at 07:34 UTC and consequently, the 
relative humidity data flatlined. 

Furthermore, after a sudden precipitation event when the max precip rate flag was tripped 
the TBRG total has not agreed with the comparison ORG or the precip rate plot. 

A loose wire connection was fixed 3/22 restoring RH and barometer data.  A damaged cable 
was repaired 5/11 restoring ORG data.
Measurements:twpsmet60sC1.b1:
  • Precipitation minimum(precip_min)
  • Relative humidity mean(relh_mean)
  • relh_sd
  • Atmospheric pressure(atmos_pressure)
  • Precipitation maximum(precip_max)
  • precip_sd
  • Precipitation mean(precip_mean)
