Subject: | NSA/GNDRAD/C2 - Upwelling PIR measurement - spikes in thermopile signal |
DataStreams: | nsagndrad20sC2.a1, nsagndrad60sC2.b1, nsagndradC2.00
|
Description: | ULH measurements have many spikes at this site. On 2/03, the anomalous spikes become
frequent and are very noticeable from 0027 - 0445 UTC. Negative and positive spikes occur on
seemingly random days until 5/27/2004. Extensive troublshooting could not resolve
problem, including a datalogger changout on 4/22. Problem seems to have resolved itself with
the last spikes occuring on 5/27/2004 approximately 1500GMT. No problems with upwelling
PIR noise are evident up until and after the conversion from Zeno to Campbell dataloggers
on 11/22/2004. |

Subject: | NSA/GNDRAD/C1 - Frosting/Condensation |
DataStreams: | nsagndrad20sC1.a1, nsagndrad60sC1.b1, nsagndradC1.00
|
Description: | The GNDRAD PIR and IRT comparison was showing the IRT 2-4 W/m^2 greater than the PIR.
Suspected snow or frost on the instrument(s). Corrective maintenance performed 10/15/04 at
21:30 UT. Optics of both instruments were cleaned. Upwelling longwave measurement
agreement restored (+/- 5 W/^2).
Although the relative performance (agreement) of the two instruments improved after
corrective maintenance (+/- 2 W/m^2), no correction is suggested because the agreement remains
with the estimated measurement uncertainty of +/- 4 W/m^2 (IRT) and +/-10 W/m^2 (Inverted
PIR) |

Subject: | NSA/GNDRAD/C2 - Incorrect calibration coefficients applied to upwelling(Gndrad)PIR |
DataStreams: | nsagndrad60sC2.b1, nsagndradC2.00
|
Description: | An insitu test comparing the Gndrad PIR and the Gndrad IRT at the NSA was performed from 6
Jan 2005 to 12 Jan 2005. The radiometer mentor requested the Eppley single calibration
coefficient for the PIR replace the 4 coefficients method developed by NREL. The Grndrad
PIR compared closer to the Gndrad IRT during this period. However, the radiometer mentor
believes the 4 coefficient PIR irradiance measurements remains superior to the single
coefficient Eppley PIR measurement method. Further questions should be directed to the
radiometer instrument mentor. |

Subject: | NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors |
DataStreams: | nsagndrad20sC1.a0, nsagndrad60sC1.b1, nsagndradC1.00
|
Description: | During the power outage the upwelling global measurement from the PSP instrument shows a
slight increase from -5 to +0 W/m2. This is due to removal of thermal offsets induced by
the AC heater during the power outage. This heater is installed within the PSP
ventilator - it is necessary for the NSA/C1 climate.
The upwelling longwave PIR instrument is unaffected due to case and dome temperature
corrections.
The IRT is AC powered and was not operational during this time period. |

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. |
