Subject: | PVC/SKYRAD/M1 - Intake Fan Failure |
DataStreams: | pvcskyrad20sM1.a0, pvcskyrad60sM1.b1 |
Description: | PSP (down_short_hemisp) ventilator fan failed from start of PVC deployment. Site ops repaired/replaced on 8/28. Instrument data are not recoverable. The down_short_hemisp data are not recoverable but can be re-constructed using the short_direct_normal and down_short_diffuse_hemispheric measurements and the following formula: Global = Direct * cos(zenith angle) + Diffuse |

Subject: | PVC/SKYRAD/M1 - Reprocess: Incorrect calibration coefficients |
DataStreams: | pvcskyrad20sM1.a0, pvcskyrad60sM1.b1 |
Description: | Incorrect programs were used in Skyrad since PVC deployment period began. The Skyrad program was corrected 09/05/2012 approx 20:00GMT. Reprocessing will be required of all instruments at this station except the IRT. This will require applying the following corrections for the time range specified. Serial numbers(incorrectly applied): PIR1-DIR: 34306 PIR2-DIR: 34303 Diffuse PSP: 34284 NIP: 34097 PSP-DS: 34293 Serial numbers(correct): PIR1-DIR: 34303 PIR2-DIR: 34306 Diffuse PSP: 35751 NIP: 37285 PSP-DS: 37302 Data: Longwave requires reprocessing using the 20second datastream and applying the following k1 coefficients (note: the longwave instruments were swapped according to datalogger). down_long_hemisp1 (old cal) = 0.23041 down_long_hemisp1 (corr cal) = 0.24750 down_long_hemisp2 (old cal) = 0.24750 down_long_hemisp2 (corr cal) = 0.23041 Shortwave only requires application of the following corrections to 1min and 20 second data. down_short_diffuse_hemisp(corr) = down_short_diffuse_hemisp(old value)*(104.45(corr cal)/120.91(incorr cal)) short_direct_normal(corr) = short_direct_normal(old value)*(117.25(new cal)/124.97(incorr cal)) up_short_hemip(corr) = up_short_hemip(old value)*(119.21(new cal)/108.48(incorr cal)) Contact radiometer mentor with any comments/questions |

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: | PVC/SKYRAD/M1 - Reprocess: Incorrect IRT Configuration |
DataStreams: | pvcskyrad60sM1.b1 |
Description: | The SKYRAD IRT was installed temporarily (waiting for the new enclosure) in a vertical orientation, without the use of the gold mirror. When irt_comm was started, the emissivity parameter in the startup file was not changed to 1.000 compensate for the absence of the mirror, resulting in a positive bias of about 5 K. These data may be corrected by adjusting the radiance values for the difference in emmissivity. |

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. |

DataStreams: | sgpsirs20sE33.a0, sgpsirsE33.b1 |
Description: | Shading of the PSP and NIP radiometers occurred after sunrise each day of the reported date period, during the time between 1145 and 1215 UTC. Issue is present in the downwelling shortwave hemispheric and shortwave direct normal variables. The shading was caused by the presence of an antenna that was later relocated. Data is to be reprocessed and designated as missing for the affected time period each day. |
