Subject: | SGP/TSI/C1 - Metadata Errors in NetCDF Header |
DataStreams: | sgptsiskycoverC1.a1, sgptsiskycoverC1.b1 |
Description: | The value of "sample_int" reported in the netCDF header is incorrect. The correct sampling interval is 30 seconds. The maximum values for the variable "sunny" is incorrect. It should be 1, not 100 as documented in the netCDF header. Users should disregard the "qc_sunny" flag during this period of time and apply their own qc check if desired. The minimum value for the variable "solar.altitude" is incorrect. It should be -90, not 10 as documented in the netCDF header. Users should disregard the "qc_solar.altitude" flag during this period of time and apply their own qc check if desired. |

DataStreams: | sgptsiC1.00, sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1 |
Description: | The TSI-880 experienced a power and/or computer failure. It was replaced with a spare TSI-440 and data collection resumed 4/5/05. Note: this is a temporary replacement. |

Subject: | SGP/TSI/C1 - Heater problem |
DataStreams: | sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1 |
Description: | The TSI was converted from a model 880 to 660 which requires separate power for the mirror heater. The heater was not powered during this period so morning dew and other condensation was not quickly evaporated. |

DataStreams: | sgptsimovieC1.a1, sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1 |
Description: | A persistent bird was landing on and polluting the mirror, multiple times throughout the day. Spikes were placed on the corners and top of the instrument (an affective deterrent in the past) but this bird had the agility to perch on the top-center of the mirror. |
