Subject: | NSA/GNDRAD/C1 - IRT cable failure |
DataStreams: | nsagndrad60sC1.b1 |
Description: | The IRT signal became very noisy and the problem was traced to the cable (after the instrument was returned to the vendor for diagnosis). The problem started occurring when ice surrounding the cable began to melt. The cable was repaired and the instrument reinstalled. |

DataStreams: | nsagndrad60sC1.b1 |
Description: | The IRT was returned to the vendor for diagnosis. It was found to be operating as expected and the signal noise problem was traced to the cable. The cable was repaired and the instrument reinstalled. |

Subject: | NSA/GNDRAD/C1 - Reprocessed: Incorrect calibration coefficient |
DataStreams: | nsagndrad20sC1.a0, nsagndrad60sC1.b1 |
Description: | Installed Gndrad PSP (upwelling shortwave hemispheric irradiance) had calibration coefficient RS applied when it should have used Rsc. ARM is using IR corrected coefficients Rsc@45 and CFc@45 for PSPs deployed at all facilities. PSP #32012F3 should use RSc@45=109.39 and not Rs@45=110.97. Reprocessed to correct upwelling shortwave hemispheric irradiance (US) by: US(new) = (US(old) / 110.97 ) * 109.39 Reprocessing completed March 2008. |

Subject: | NSA/GNDRAD/C1 - Upwelling PIR ventilator fan failure |
DataStreams: | nsagndrad20sC1.a0, nsagndrad60sC1.b1 |
Description: | The PIR exhibited a positive bias of approximately 6 W/m2 compared to the upwelling IRT due to ventilator fan failure. Thus, the up_long_hemisp, data stream is high by about 6 W/m2. Bias is not consistent and depends on atmospheric conditions. Either disregard the up_long_hemisp data or use the IRT for an estimate of the up_long_hemisp values during this time period. |

Subject: | NSA/GNDRAD/C1 - Net radiometer removed |
DataStreams: | nsagndrad60sC1.a1, nsagndrad60sC1.b1 |
Description: | The net radiometer was removed from the NSA.C1 GNDRAD instrument suite on Feb 3, 2000. Net rad variables were filled with garbage data until Sept 23, 2000 and with missing values (-9999) until 20041103. The net rad variables were removed from the netcdf files after 20041103. A reprocessing task (RID-526) has been submitted to the queue to address the need to add metadata to the NSA.C1 GNDRAD netcdf files documenting the missing data as well as to move toward a consistent datastream format throughout time. |

Subject: | NSA/GNDRAD/C1 - Reprocess: IRT insufficiently heated |
DataStreams: | nsagndrad60sC1.b1 |
Description: | IRT had insufficient heating to maintain an internal reference temperature above 0 degrees C. Measurements of surface temperature were over-estimated when instrument was below freezing. Data will be reprocessed, but users can correct data using the following correction factor: If T_reference < -5?C, then IRT_corrected = (IRT_original - 32.993K)/0.87238 where T_reference can be estimated with the ambient temperature (e.g. inst_up_long_hemisp_dome_temp or inst_up_long_dome_temp) |
