| TR-5251 40415-1006 | 2021-07-02 | Lab none | Repair | Lab none | I replaced the spliced cable with a new cable, no splicing needed. The ring terminals I had were a bit too large for the screw terminals inside the bucket, so I cut off a portion of the ring to make it more like a spade terminal. |
| TR-5251 40415-1006 | 2021-06-22 | Mayberry Precipitation | Removed | Lab none | Removed from MB and brought back to the lab for repair. It had lots of tips even though there hasn't been any rain, probably because the spliced area of the cable was underwater. |
| LI-7500A 0073 | 2021-06-28 | Lab none | Tested | Lab none | I ran zero and span gas through this IRGA again today. I didn't see the noisy signals I noticed during the last calibration. Calibrate it again before putting it back on a tower and keep an eye on it. |

Last calibration: 2021-01-20 RSSI=80.2%, Optical RH=23% Ambient P=101.5kPa, Tair=34.5C Zero Air at 1800psi, AMP CA04119 4.2238 at 1800 CH4 Zero Offset: -0.015ppm CH4 Span Offset: -0.0338ppm Notes: This 7700 was just returned from Nick and Sabina who were using it on Staten. They calibrated it on 2021-01-20 but I don't have notes on that. Also I uploaded the TG1-0224 config file before the calibration and again after calibration but I don't think that has any affect on the calibration or measurements. |

| PAR-LITE 060831 | 2020-06-04 | Factory none | Calibration | Factory none | y=mx+b 149.48 0; The date for this entry is made up but allows this calibration to be used as needed. After discrepancies with an inter-comparison on Tonzi Tower in the spring to 2021 and a conversation with Sebastien Biraud on 2021-05-05 we learned that the OSU calibration for this senor was no good and the subsequent calibration that this entry represents should be used instead. The OSU calibration uses a lamp and fails for certain PAR sensors for unknown reasons. This calibration is done at LBL outside under ambient conditions cross compared with ten other PAR sensors. |

Zero gas was an AMP cal gas in a baby tank that we borrowed for the day. Zero offset and span are a bit higher than I usually see on 7700s. A lot of bounce in concentrations from Dennis and Robert talking and wiggling the upper boardwalk. |
