DataStreams: | twpskyradC2.00, twpskyrad60sC2.a1, twpskyrad60sC2.b1 |
Description: | On several occasions, large (10 percent) differences between the global PSPs and the NIP were observed. In each case, the NIP reported low relative to the direct flux reported by the PSPs. These occurences persisted for several days each time and are likely due to salt on one or more of the radiometers. |

DataStreams: | twpskyrad60sC2.a1, twpskyrad60sC2.b1 |
Description: | During Reset7 (8/6) the skytracker firmware was upgraded for Y2K. While still at the site, the mentor noted that the tracker was sticking and replaced it on 8/8/99. The replacement tracker also failed. Repeated attempts through 8/13 were not successful. After 8/13, the tracker was not operational. It was found that the problem was the result of bugs in the Y2K compliant version (2.44) of the firmware. On 10/14, Jeff Zirzow installed a new tracker with the Y2K non-compliant version (2.43) of the firmware. It was correctly assumed that the Y2K issues would only be apparent at the 19991231-20000101 time boundary. Exact times of changes are not known; noon GMT (midnight Local) was used to adequately window the time period of the changes. |

DataStreams: | twpskyrad60sC2.b1 |
Description: | On 17Sep01 the Global PIR was moved from the unshaded position on the Skyrad stand to the new 'shaded' spot on the new K&Z tracker. It is still using the same Logger channel as it did as an unshaded PIR even though it is now shaded. |

Description: | The UVB was not temperature controlled to 25C as required to ensure accurate data. UVB data should ONLY be used after checking both the bit_data and twpskyrad20sC1.a1 uvb_temp or inst_down_uvb_temp. UVB data where the UVB temperature was outside the range of 24-26C should not be used. |

Subject: | TWP/SKYRAD/C2 - IRT affected by rain or shutter |
DataStreams: | twpskyrad60sC2.a1, twpskyrad60sC2.b1 |
Description: | During this time period, the SKYRAD IRT data was affected by rain events due to a shutter which was installed to protect the optics from being emersed in rainwater. While the shutter was closed, or if water got on the lens, the IRT data was invalid. If water did get on the lens, the contamination usually persisted until an operator cleaned the optics. The configuration of the IRT was changed Oct 29, 2001. The IRT was mounted such that the field of view is directed downward at a 30 degree elevation angle and reflected to the vertical by a front-surfaced, gold-plated mirror. This configuration prevents rain from directly striking the lens and collecting in the lens barrel. Data from 11/98-2/99 were examined and times when the data are invalid are identified below. Data from 3/99-10/01 also contain periods of invalid data, but it is left to the data users to identify those periods and filter the data according to their needs. 12/10/1998 04:30 - 12/10/1998 05:30 12/10/1998 11:30 - 12/10/1998 12:30 12/10/1998 13:00 - 12/10/1998 17:00 12/17/1998 02:30 - 12/17/1998 04:00 12/17/1998 13:00 - 12/17/1998 15:00 12/23/1998 18:00 - 12/23/1998 20:00 12/30/1998 21:00 - 12/31/1998 03:00 01/12/1999 22:35 - 01/12/1999 23:45 01/13/1999 14:16 - 01/13/1999 16:35 01/13/1999 21:41 - 01/13/1999 23:30 |
