DataStreams: | nsaskyradC1.00, nsaskyrad20sC1.a0, nsaskyrad20sC1.a1, nsaskyrad60sC1.b1
|
Description: | Both PIRs reported unreasonable high readings with coincident low reading from the IRT.
Since both PIR instruments exhibited exactly the same behaviour and the IRT an opposite
response during large suspect data excursions this indicates that the false signal maybe the
result of poor grounding.
The PIR1,2 data and the IRT data are most adversely affected. During the problem periods
PIR irradiance increased (typ pos 200-300W/m2) while the IRT response was negative (typ
neg 20-30W/m2) but followed the response of the PIR. The Skyrad shortwave instruments
were also affected but to much less extent (within their uncertainties). Data quality flags
are typically not triggered during these problem periods.
Data logger grounding was improved on 6/10 2005. The problem hasn't re-occurred since
that time. |

Subject: | NSA/SKYRAD/C1 - Instrument noise |
DataStreams: | nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
|
Description: | Skyrad data appears affected by noise creating bias in analog voltage readings on
02/15/2006 from 1300-1800GMT and again on 02/16/2006 from 1300-1500GMT. The second night the
noise is attenuated significantly. By 02/17 no bias/noise is detectable. The thermistor
measurements in PIR1 and PIR2 were unaffected during these excursions and showed no
deviation from normal during the problem period. In addition, the onboard logger temperature and
battery voltage read normal throughout. The problem has not reappeared as of 4/25/2006. |

|
Description: | BarrowC1, Gndrad. On Aug 11th the PSP-US was changed out and the Campbell program was
changed to reflect this. However, an old program that uses the 4 coefficient PIR cal factors
was used. The PIR-UIR was not changed out, however, the logger program coeffs reverted
back to the 4 Coeffcients. The Eppley PIR-UIR coefficients for this S/N 30168F3 are :
K0=0.0, K1(aka k)=.25253, K2= 1.0, K3=-4, Kr=0.0. |
