NIM/MET/M1/S1 - Reprocess: ORG Data has very small rainrate values
DataStreams:nimmetS1.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.
Suggestions: 
Measurements:nimmetS1.b1:
  • Precipitation rate standard deviation(precip_rate_sd)
  • Precipitation rate, domain mean(precip_rate_mean)
  • Precipitation rate maximum(precip_rate_max)
  • Precipitation rate minimum(precip_rate_min)
