Subject: | SGP/SIRS/E33 - Instrument noise problem |
DataStreams: | sgpsirs20sE33.a0, sgpsirsE33.b1 |
Description: | The UIR instrument (up_long_hemisp) had significant noise starting from the commission date. On 8/14/2012 15:59 the UIR was replaced which corrected the noise problem. |

Subject: | SGP/SIRS/E33 - Instrument noise problem |
DataStreams: | sgpsirsE33.b1, sgpsirs20sE33.a0 |
Description: | During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) pyrgeometers were swapped to help isolate an instrument noise issue. After this swap it was determined that the noise was associated with this specific instrument. For the time range specified 8/14 to 8/17 the DIR data are not recoverable since the instrument was faulty (it was the old bad UIR). The instrument was replaced with spare on 8/17. |

Subject: | SGP/SIRS/E33 - Reprocess: Incorrect UIR calibration |
DataStreams: | sgpsirs20sE33.a0, sgpsirsE33.b1 |
Description: | During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) pyrgeometers were swapped to help isolate an instrument noise issue. The replacement UIR instrument installed on 8/14 had incorrect calibration coefficients applied. The serial number was correct. wrong UIR k1 cal = 0.2376 correct UIR k1 cal = 0.2451 Data from 8/14 to 9/26 will be reprocess. |

Subject: | SGP/SIRS/E33 - Reprocess: Incorrect DIR calibration |
DataStreams: | sgpsirs20sE33.a0, sgpsirsE33.b1 |
Description: | During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) pyrgeometers were swapped to help isolate an instrument noise issue. That swap resulted in bad DIR data from 8/14-8/17 (documented in D121010.1) A replacement DIR instrument installed on 8/17 had incorrect calibration coefficients applied. The serial number was correct. wrong DIR k1 cal = 0.2967 correct DIR k1 cal = 0.3086 Data from 8/17 to 9/26 will be reprocess. |

Description: | During the time range specified the UIR and DIR serial numbers are correct but incorrect calibration coefficients were applied in the datalogger. up_long_hemisp (SN# 30058F3) wrong k1 cal :0.2679 W/(m^2*uV) correct k1 cal: 0.2740 W/(m^2*uV) down_long_hemisp (SN# 30085F3) wrong k1 cal :0.2376 W/(m^2*uV) correct k1 cal: 0.2451 W/(m^2*uV) Data will be reprocessed. |
