Subject: | SGP/CSPHOT/C1 - Not Performing Zenith Observations (Cloud Mode) |
DataStreams: | sgpcsphotaotC1.a1, sgpcsphotsizeC1.a1 |
Description: | There were problems associated with the implementation of "cloud mode" on the upgraded CSPHOT system resulting from problems with the programming on the internal EPROM. The "cloud mode" did not work properly and other observations were also affected. For example, early morning sun and almucantar observations were missing. On 4/30/2007, the instrument was re-installed with cloud mode and was verified to be working. |

Description: | The instrument was temporarily replaced while the primary instrument was out for repairs. Data should be unaffected, however, zenith observations are not available during this time period. On 4/30/2007, the primary instrument was re-installed with cloud mode and was verified to be working. |

Description: | There was a distinct cosine curve in the AOD data, which indicated a problem with the instrument, possibly due to a bad eprom in the control box. The instrument was removed from service on 7/24/08 and replaced on 9/24/08. |

DataStreams: | sgpcsphotaotC1.a1 |
Description: | There was a possible obstruction or instrument malfunction, causing errors in the data and showing diurnal dependence in the AOT data. Use the quality assured level 2.0 AOT data from AERONET when available (sgpcsphotaotfiltqaC1.a1). Level 2.0 data and post-calibration level 1.5 data should become available in 2014. Users can also use MFRSR data if available. |

Subject: | SGP/CSPHOT/C1 - Aerosol Optical Depth biased high for unknown reasons |
DataStreams: | sgpcsphotaotC1.a1, sgpcsphotsizeC1.a1 |
Description: | During this time period the aerosol optical depth is biased high by about +1. It apparently corrected itself at the end of this period so the cause of the offset is undetermined. It likely affected all the other data-products as well. The 3 point variance used to filter cloud affected observations are also unusually high even for cloud free days, so most data will already be marked bad automatically in the higher order products. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgpcsphotsizeC1.a1, sgpcsphotaotC1.a1 |
Description: | On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |
