Subject: | PYE/SKYRAD/M1 - Reprocessed: IRT configuration and calibration |
DataStreams: | pyeskyrad20sM1.a0, pyeskyrad60sM1.b1, pyeskyradM1.00 |
Description: | The configuration of the IRT was inadvertently set to default and the program of the data loggers were changed to that used at TWP.C3. This caused the calibration of the data to be wrong. It was corrected by reconfiguring the IRT and changing the conversion factors in the data logger program. These data have been reprocessed to apply correct calibrations and the reprocessed data were archived in February, 2007. |

Subject: | PYE/SKYRAD/M1 - IRT bias |
DataStreams: | pyeskyrad60sM1.b1 |
Description: | The SKYRAD IRT measured lower sky temperatures than the AERI. This may have been due to a dirty mirror or lens. |

Subject: | NIM/SKYRAD/M1 - IRTs do not agree with AERI |
DataStreams: | nimskyrad60sM1.b1 |
Description: | Since deployment at PYE, and then at NIM, the AMF SKYRAD IRT measured about 10K higher sky temperatures than the AERI and the MWRP IRT measureed about 20K higher than the AERI. Several actions were taken to diagnose the problem including confirming the correct configuration of the IRTs and data logger, cleaning the mirror and lens, and replacing the mirror. After several days of rain beginning 6/2/2006, the three instruments came into agreement. It is unknown whether this was a problem with the AERI, MWRP-IRT or SKYRAD-IRT. |

Subject: | NIM/GNDRAD/M1 - Reprocessed: Longwave calibration error |
DataStreams: | nimgndrad60sM1.b1 |
Description: | Modified pyrgeometer calibration procedures were implemented beginning in December 2003. These modified procedures introduced a calibration bias in the longwave data. The previous procedures were re-implemented at all sites between December 2005 and February 2006 to restore proper calibrations. The data collected while the incorrect procedures were in place have been reprocessed to remove the calibration bias. The reprocessed 60 second averaged data are based on 3 instantaneous 20 second data records rather than on 60 1 second instantaneous data records. Still, these data are considered far superior to the originally processed data. The reprocessed data were archived in February 2007. |

Subject: | NIM/SKYRAD/M1 - Tracker inoperative |
DataStreams: | nimskyrad20sM1.a0, nimskyrad60sM1.b1, nimskyradM1.00 |
Description: | Starting on 9/12 the NIM radiometer tracker drifted enough due to sinking supports and a drifting clock that the direct normal measurments (NIP) and the downwelling hemispheric diffuse shortwave measurments (8-48) were adversely affected in the afternoon hours. The shortwave hemispheric global instrument (PSP) and downelling hemispheric longwave shaded1 and shaded2 (PIR) are unaffected by this problem. The tracker problem greatly affected direct measurements and affected the diffuse measurement to a lesser extent. There are no redundant measurements for these instruments. However, during this time range the data collected before local noon (aprox 1140GMT) for all shortwave Skyrad instruments appear to be good. |

Subject: | FKB/SKYRAD/M1 - IRT bias |
DataStreams: | fkbskyrad60sM1.b1 |
Description: | On several days (especially in April, September, and December), the sky temperature measurement from the IRT exhibited a positive bias from the AERI measurement from about 20:00 to 07:00. This diurnal variation is highly correlated with the measurement of relative humidity so was most-likely due to the contribution of the temperature of water vapor, fog, and/or condensation on the lens and/or mirror. |

Subject: | FKB/GNDRAD/M1 - Reprocessed: Incorrect calibrations |
DataStreams: | fkbgndrad20sM1.a0, fkbgndrad60sM1.b1 |
Description: | An incorrect calibration coefficient was applied to the up_short_hemispheric instrument (PSP) for the specified time period. Changes in the ARM PSP calibration procedure now generates two different calibration coefficients for the same instrument, Cf(non "IR corrected")and Cfc("IR corrected"). CFc should have been applied to this instrument but CF was erroneously used. The affected PSP is S/N 34292F3 Cf=117.61 (incorrect applied), Cfc(correct)=116.07W/m2/mV These data were reprocessed and archived in March 2008. |
