Subject: | PVC/GNDRAD/M1 - Reprocess: Incorrect calibration |
DataStreams: | pvcgndrad20sM1.a0, pvcgndrad60sM1.b1 |
Description: | Incorrect program used in Gndrad since PVC deployment period began. The Gndrad program was corrected 10/04/2012 approx 20:17GMT. Reprocessing will be required of the upwelling PSP (up_short_hemsip). This will require applying the following corrections for the time range specified. Serial number: serial number(original) = 30938 serial number(corrected) = 37297 Data: up_short_hemip(corrected) = up_short_hemisp(original)*(113.25(new cal)/129.42(old cal)) |

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: | 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. |

Subject: | PVC/SKYRAD/M1 - Instrument noise problem |
DataStreams: | pvcskyrad60sM1.b1, pvcskyrad20sM1.a0 |
Description: | All instruments on Skyrad exhibit intermittant erratic behavior from 10/05 through 10/23. Appears to have been an grounding issue with the Infrared thermometer (IRT) installed on Skyrad and replaced 10/17. After the last problem period on 10/23 the problem resolved itself without operator involvement. |
