|---|---|---|---|---|---|
| LI-7500A 0035 | 2023-04-03 | Mayberry Gas Analyzer CO2/H2O | Removed | Lab none | Removed from Mayberry for calibration. Replaced by sn 0418. |
| JAZ-EL350 JAZA2903 | 2023-04-06 | Lab none | Adjusted | Lab none | Adjusted clock from 15:03 to 15:45 PST. This clock probably needs to be reset every few months. |
| HMP45A S4220026 | 2023-03-29 | Lab none | Serviced | Lab none | Cut off the 75' cable to solder on to HMP45 sn D4420029, which will be used by Allen Goldstein's lab on their BWW urban tower. The sensor itself is still stashed in the sensor cabinet because it might have some useable parts. |
| HMP45AC D4420029 | 2023-03-30 | Lab none | Loaned | Loaned none | Given to Erin Katz from Allen Goldstein's lab. They will use this sensor on their BWW urban tower. |
| HMP45AC D4420029 | 2023-03-29 | Lab none | Serviced | Lab none | Spliced on 75' cable from HMP45A sn S4220026 so the new cable length is 125'. I ran this sensor for a few hours in the lab and all seemed well. This sensor will be used by Allen Goldstein's lab on their BWW urban tower. The original HMP on the urban tower was connected to the analog inputs on the 7700 sn TG1-0421, but we've had to remove the 7700 because of water damage so they need an HMP with a long cable to hook up to their boiler room equipment. |
| LI-7700 TG1-0421 | 2023-03-28 | Lab none | Shipped | Factory none | Shipped back to Licor for repair. Expecting a 4-6 months turnaround time |
| LI-7700 TG1-0421 | 2023-03-24 | Loaned none | Removed | Lab none | Removed from the BWW urban tower because it was not working. Joe opened it and found a bunch of water inside the bottom can. There is corrosion on the boards and will need to be returned to Licor for repair. |

I didn't really notice this for other sensors I calibrated today but I'll need to pay more attention next time. Previously, there was a large offset in CO2 span. Need to keep an eye on this sensor. |

| GP-001 GP20200089 | 2023-03-23 | Gilbert Tract CO2 Probe | Removed | Lab none | Removed from Gilbert Tract (was installed by the staff gauge) and brought back to the lab for testing. I think this sensor is dead. |

I entered all the coefficients by hand. Afterwards it was pretty right on except for CO2 span. Not sure why but decided to do the calibration. |
| LI-7550 AIU-1569 | 2023-03-14 | Lab none | Tested | Lab none | I tested this box in the lab. It had been removed from the field because the door was left open and it got wet inside. I had cleaned it up earlier but I'm not sure if I ran it before. Today, it was running but very slowly/laggy. At first I was concerned it was the new laptop but it was the same on the old laptop. I pulled the shroud off and found a little corrosion on one of the ribbon cable connectors. I cleaned this off and it seems to be working ok. |

| BB-Fab BB-TZ_soilco2 | 2023-03-01 | Tonzi Battery Bank soil co2 | Replaced | Tonzi Battery Bank soil co2 | I brought the three batteries last remove from HS and put them under the solar panels. I rewired all the panels into a terminal strip. I used one of the old batteries for the fence charger and brought the rest in. |

| PS-15M 12501588 | 2023-03-02 | Lab none | Tested | Disposed none | This charge controller hasn't been showing solar amps. I took it apart and cleaned out a bunch or large dead ants. I found two diodes and one capacitor that looked a little fouled but not obviously broken. I'm not sure I have the tools/skills to do any more. I cleaned it up, put it back together and tested it. Now the screen shows nonsense - different on each power cycle. I think it's a goner. Put it in the e-waste box. |

After calibration, swapped desiccant and flushed headspace with zero air until new optics RH=10%. Sensor removed this morning and will go back up on the BWW urban tower this afternoon. |

Sensor installed on BWW urban tower for the past 10 months. Sensor removed this morning and will go back up on the BWW urban tower this afternoon. I updated the calibration coefficients directly on the BWW computer instead of uploading the new config file. I also swapped the HMP fan its screw terminal that was all corroded. |

| LI-7500A 1594 | 2023-01-27 | Lab none | Tested | Lab none | Ran in the lab on the bench for 2 days and used eddypro to calculate the 30-min concentrations. CO2 and H2O data seemed reasonable: CO2 ranged from 420 to 510ppm and H2O ranged from 250 to 450 mmol/m3. Not sure why this sensor wasn't working in the field. |
| SRS-Ni NDVI 2046503354 | 2023-01-25 | Lab none | Tested | Disposed none | Removed the spliced cable and tested in the lab. Still no response on the terminal emulator. This sensor is probably dead. It's weird that both incoming and outgoing sensors went bad at the the same time. Both sensors had spliced cables and were connected to the same C port and the same pluggable power block. One of the spliced wires for data (red) had a few cracks in the plastic sheath; maybe it shorted against the bare G wire and killed both sensors. |

I think it's ok for now but something to keep an eye on. H2O value was not stabilizing when dewpt generator was set to 20.00C, probably because the room's dewpt<20.00C. I set the span point to 16.00C instead, which worked well. |

At first, large H2O span offset (-0.32) than usual. The condenser water tube in the back was low on water. I opened the cap to let water level rise again. Afterwards, H2O span was right on (offset 0.01). |
| RPI0W RPI0W-003 | 2023-01-04 | Lab none | Tested | Lab none | Plugged in in the lab but the picam could not boot all the way. The microSD card is probably busted from flickering power at the end of December. Joe put in a new microSD card and loaded the fwb code (r=1.8, b=1.8). We had some trouble getting the RTC recognized by the picam, but in the end it worked with a brand-new RTC and brand-new coin cell battery. Ran overnight in the lab and it seems fine. |

| eosFD FD20180067 | 2023-01-10 | Lab none | Tested | Lab none | Tested in the lab and it turned on once we plugged in the power with its original cable, hallelujah. Data started being weird (spiky and/or 0) in mid-December when the field started flooding. However, during the performance check the CO2 concentrations were consistently all over the place, even after trying to reset it. This chamber probably needs to go back to the factory. |
| eosFD FD20180067 | 2023-01-03 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from BC and brought the chamber and cable back to the lab for testing. We found it floating in the water underneath the tower. The cable connector was underwater. |
