Subject: | SGP/MFRSR/C1 - Out-of-band filter leakage |
DataStreams: | sgpmfrsrC1.b1 |
Description: | Testing of the batch of centrovision filters being used in the MFRSR C1 instrument indicate that the first four filters leak 'out of band' light. The leakage for each filter is (1)415nm 3%, (2)500nm 1-2%, (3)615nm 1-2%, (4)673nm 3%. Acceptable leakage is less than 0.5%. This leakage causes an error in the irradiance values (too high) at these four wavelengths and the optical depths calculated using this data will be too high. |

DataStreams: | sgpmfrsrC1.b1 |
Description: | During this time period the broadband and 500nm channels intermittently reported erroneously high values due to a problem with the instruments loggerboard. The other channels were unaffected. This problem is sometimes evident as a sudden "step" shift in the values. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgpmfrsrC1.b1 |
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. |

Subject: | SGP/MFRSR/C1 - Irradiances too high |
DataStreams: | sgpmfrsrC1.b1 |
Description: | After the A/D convertor lock-up was corrected on 981014, the irradiances as measured by the MFRSR were about 20% too high. 981018 is a particular egregious example of measured irradiances that are too large. Cause of the problem is not known, though suspect some moisture got into the instrument (this was a period of much precipitation). After 981024, the MFRSR settled down and the irradiances returned to a normal range. |
