Subject: | NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | nsasondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060929: alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data. |

Subject: | NSA/SKYRAD/C1 - IRT mirror heater failure |
DataStreams: | nsaskyrad20sC1.a0, nsaskyrad60sC1.b1 |
Description: | The heater of the IRT gold mirror failed due to a broken wire (that probably occurred on 12/13 during maintenance of the solar tracker) allowing snow and frost to accumulate on the mirror until it was cleared during daily preventative maintenance. The problem was corrected when the heater wires were replaced. |

Subject: | NSA/SKYRAD/C1 - Direct and Diffuse incorrect |
DataStreams: | nsaskyrad20sC1.a0, nsaskyrad60sC1.b1 |
Description: | The short_direct_normal (NIP) instrument and cable were damaged by tracker rewind malfunction. Tracker and NIP replaced on 4/22 2200GMT but tracker not operational until 4/23 1815GMT. Thus, down_short_diffuse_hemisp (8-48) was not shaded 4/22 to 4/23. Do not use 8-48 data from 4/22 to 4/23. NIP data is not recoverable during entire time but can be estimated using component sum for each 1 minute data: Direct = (global - diffuse)/cos(zenith angle) |

Subject: | NSA/SKYRAD/C1 - Tracker inoperative |
DataStreams: | nsaskyrad20sC1.a0, nsaskyrad60sC1.b1 |
Description: | Tracker stopped working at this site during the time range specified. Reason for failure is unknown. Tracker power cycled and restarted by maintenance 06/30 2008 1740 GMT. The short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data are bad during this time. Data are not recoverable. |

DataStreams: | nsatpsC1.b1 |
Description: | The data were incorrectly collected and processed at 1 second temporal resolution rather than 1 minute resolution. Data will be reprocessed to average to 1 minute. Data quality are not compromised by this resolution error. |

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. |

DataStreams: | nsametC1.b1, nsatwrC1.b1 |
Description: | New wind sensors and new T/RH probes were being installed during this time period. The tower booms were lowered and much of the data collected were not at listed heights nor were the data accurate due to configurations during install. |
