| LI-7500A 0041 | 2021-09-21 | Lab | Calibration | Lab | Last calibration: 2021-05-25 AGC=98 SDM= DAC1= DAC2= Ambient P=100.3kPa, Tair=26.6C, Tdew=11.3C Zero Air at 1700psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero 0.9966 -> .9667 Offset: .29ppm CO2 span 1.0137 -> 1.0145 Offset: -.44ppm H2O zero 0.8206 -> .8224 Offset: 10.9ppm H2O span 1.0266 -> 1.0228 Offset: .09ppm Notes: Calibrated zero and CO2 span on 9/20. There was an issue with the dew point generator where it was producing a dewpoint ~16C when the temp switch was set to 20.00C. I calibrated the H2O span the next day on 9/21. We fixed the problem by adding more water in the condenser block on the back of the machine. The water level looked ok while the cap was on and the machine was running, but once I turned the machine off and took the cap off, the water level dropped to below the "Min" line. After I added water and turned it back on, the dewpoint generator got to a reasonable dewpoint and it seemed stable. |
| LI-7500A 75H-2176 | 2021-09-21 | Lab | Calibration | Lab | Last calibration: 2021-06-07 AGC=100 SDM= DAC1= DAC2= Ambient P=100.6kPa, Tair=29C, Tdew=11.4C Zero Air at 1550psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero 0.8673 -> .867 Offset: -1.56ppm CO2 span 1.0067 -> 1.0023 Offset: 3.07ppm H2O zero 0.8536 -> .8526 Offset: -5.5ppm H2O span 0.9148 -> .9091 Offset: .14ppm Notes: |
| LI-7500A 0418 | 2021-09-21 | Lab | Calibration | Lab | Last calibration: 2021-09-20 AGC=99.3 SDM= DAC1= DAC2= Ambient P=100.7kPa, Tair=29C, Tdew=11.1C Zero Air at 1600psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero .9004 -> .8992 Offset: -4.8ppm CO2 span 1.0016 -> .9972 Offset: 3.22ppm H2O zero .8444 -> .8490 Offset: 27.3ppm H2O span .9808 -> .9774 Offset: .08ppm Notes: I swapped the chemicals immediately before this calibration run. The chemicals were a tad sticky at the top but after a bit of poking with a screwdriver it was easy to dump the chemicals out into the waste jar. I don't think the chemicals needed to be changed necessarily. Before inserting the new chemical bottles, I ran some zero air into the headspace. This run was just to see what the numbers looked like. I will let it run on a bench for a week and calibrate again next week. |

I'm going to try changing the chemicals and calibrating again. |

Again the calibrations seem to be right on, but the noise around the set values is two the three times greater than our other IRGAs. I'm planning to send it in for retrofit. |

| GP-001 GP20160070 | 2021-08-26 | Lab none | Notes | Lab none | Partly cleaned this sensor and tried to take the cable off. However, the connector at the top of the sensor twists loose from the body of the sensor so I don't think it's worth keeping. I'm not sure if the connector was already loose, or if I loosened it trying to table the cable off. |

This was a double check of the last check since the CO2 concentrations were so far from ambient. The two chambers were still offset: Average Flux: 1.3, 0.37 STDEV Average ATM: 343.7ppm, 41.5C Average Soil: 408.5ppm, 41.5C Need to ask Eosense again. |

| eosFD FD20180048 | 2021-07-29 | Tonzi-SoilCO2 Forced Diffusion Tree 1 | Maintenance | Tonzi-SoilCO2 Forced Diffusion Tree 1 | I unfastened this chamber and laid it on its side for a performance check. Average Flux: 0.0, 0.04 STDEV Average ATM: 242.5ppm, 51.9C Average Soil: 243.0ppm, 51.7C I reset the baseline CO2 concentration to 400ppm. This chamber does not have a sun shield and even though it was in the shade under the trees its temperatures were very high. |
| eosFD FD20190027 | 2021-08-04 | Lab none | Maintenance | Lab none | This chamber was removed from the Mayberry boom because its readings looked bad. In the lab I cleaned it up. There are what look like tooth or claw marks on most of the filter windows but no breaks. The initial performance check had the first of the five measurement way off which skewed everything, but its concentrations were about -140ppm. I reset the concentrations to 400ppm and did a second performance check. The second check was much better: Average Flux: -0.1, 0.05 STDEV Average ATM: 378.1ppm, 32.0C Average Soil: 374.8ppm, 32.0C I reset the baseline CO2 concentration to 400ppm again. I think this chamber can be swapped back into the field as needed. |

| MNKID-B KB04456 | 2021-07-15 | Lab none | Upgrade | Lab none | The screen on this unit seemed to be black but at an extreme viewing angle the text could be seen on top of solid dark LCD boxes. It seems to be intermittent and not controllable with the LCD back light and contrast controls. I updated the firmware to v1856. v1864 is the newest firmware, but I could not get it to load that version. I also set it up to spit out serial data at 57600 baud but still haven't figured out how to decode it. |
