Subject:
NSA/GNDRAD/C1 - Noisy PIR Data
DataStreams:nsagndrad60sC1.a1, nsagndrad60sC1.b1
Description:
During the period referenced, the ground PIR was noisy in  
              comparison to the the sky PIR data.  (Note U021211.1 documents
              same problem for 9/1/98-2/28/99)

              The noise problem continued after the GNDRAD data logger was 
              replaced in late September. Particularly strong examples of the 
              noise can be seen in data from 11/10 - 11/19/99. The peak to 
              peak noise reaches 12 W/m2.
Measurements:nsagndrad60sC1.b1:
  • PIR1 unshaded minimum(pir1_min)
  • PIR1 unshaded maximum(pir1_max)
  • PIR1 unshaded mean(pir1_mean)
  • PIR1 unshaded standard deviation(pir1_sd)
nsagndrad60sC1.a1:
  • PIR1 unshaded standard deviation(pir1_sd)
  • PIR1 unshaded mean(pir1_mean)
  • PIR1 unshaded maximum(pir1_max)
  • PIR1 unshaded minimum(pir1_min)

Subject:
NSA/GNDRAD/C1 - IRT data noisy
DataStreams:nsagndrad60sC1.a1, nsagndrad60sC1.b1
Description:
After re-installation of the IRT on 12/10/99, the data are noisy. Source of the noise is 
believed to be the heater connected directly to the IRT.  Instrument was taken offline on 
12/30/1999 and shipped back to PNNL for repair/testing.
Measurements:nsagndrad60sC1.b1:
  • IRT1 minimum(irt1_min)
  • IRT1 maximum(irt1_max)
  • IRT1 standard deviation(irt1_sd)
  • IRT1 mean(irt1_mean)
nsagndrad60sC1.a1:
  • IRT1 standard deviation(irt1_sd)
  • IRT1 mean(irt1_mean)
  • IRT1 maximum(irt1_max)
