Subject:
NSA/AOS/X1 - Reprocess: impactor, PSAP and dry nephelometer over period
DataStreams:nsaaosimpactorX1.b1, nsaaospsap3wX1.b1, nsaaosnephdryX1.b1
Description:
An ingest problem resulted in no impactor data being ingested over the specified period. 
When these impactor data are reprocessed, impactor-dependent b1-level PSAP and dry 
nephelometer data should also be reprocessed over this period to ensure that the impactor state 
is correctly depicted in those products.
Suggestions: 
Measurements:nsaaosimpactorX1.b1:

  • Impactor state in terms of aerodynamic diameter cut off(impactor_state)

    the sample being measured is 1 um or smaller.(P_1um_hourly_average)
