|---|---|---|---|---|---|
| LI-7500A 75H-2180 | 2023-03-29 | Lab | Calibration | Lab | Last calibration: 2022-12-05 AGC=100.7 SDM= DAC1= DAC2= Ambient P=99.8kPa, Tair=18.7C, Tdew=6.3C Zero Air at 1300psi, AMP CA04119 524.77 at 1150 Tdewspan=16.00 CO2 zero 0.9145 -> .9149 Offset: 2.13ppm CO2 span 1.0433 -> 1.044 Offset: -.33ppm H2O zero 0.8933 -> .8913 Offset: -12.8ppm H2O span 1.0381 -> 1.0275 Offset: .22ppm Notes: Had to use 524.45 as "span point" for sensor to read 524.77 after spanning. 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 GP20210002 | 2023-03-23 | Lab none | Installed | Gilbert Tract CO2 Probe | Installed at Gilbert Tract on a post (just off the far end of the boardwalk) with the other water quality sensors. Should be at the same height as before (about 5cm above the soil) |
| 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. |

| PS-15M 12501588 | 2023-03-01 | Tonzi Solar Controller Soil CO2 | Removed | Lab none | This solar controller has not been showing solar amps and doesn't seem to charge batteries. I brought it in for testing |
| 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. |

| LI-7550 AIU-1866 | 2023-03-02 | Bouldin Corn Interface LI-7550 | Removed | Lab none | Unit is receiving 24V but no LED lights and couldn't connect. Removed from BC tower and brought back to the lab for testing. |
| 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. |

Last calibration: 2022-06-01 RSSI=79%, Optical RH=23% Ambient P=101.3kPa, Tair=19.5C Zero Air at 1400psi, AMP CA04119 4.2238 at 1275 CH4 Zero Offset: -.011ppm CH4 Span Offset: .0138ppm Notes: First calibration since sensor was installed on BWW urban tower 7 months ago. 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. |

AGC=101.8 SDM= DAC1= DAC2= Ambient P=101.3kPa, Tair=17.9C, Tdew=4.5C Zero Air at 1400psi, AMP CA04119 524.77 at 1250 Tdewspan=16.00 CO2 zero 0.9016 -> 0.9035 Offset: 7.88ppm CO2 span 1.0075 -> 1.0257 Offset: -12.34ppm H2O zero 0.8707 -> .8731 Offset: 16.0ppm H2O span 1.0158 -> 1.0331 Offset: -.36ppm Notes: First calibration in 11 months. 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. |
| LAI-2270C PCA-3914 | 2023-02-02 | Lab none | Loaned | Loaned none | Loaned to Manuela Girotto for snow field canopy cover survey. Items loaned include console, 2 wands, 8 AA Ni-MH batteries, Ni-MH battery charger, tripod, and black plastic case with manual, USB cable, and various view caps. |
| 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'll run it for a few days in the lab to see if it's stable. |
| RPI0W RPI0W-006 | 2023-01-18 | Lab none | Installed | West Pond none | Installed at West Pond for an intercomparison with the Canon camera. Temporarily ziptied to the bottom of the Canon enclosure arm. Facing west, same direction as the Canon camera. |

I swapped the desiccant. |

| LI-7500A 0035 | 2023-01-13 | Lab | Calibration | Lab | Last calibration: 2022-08-25 AGC=99.4 SDM= DAC1= DAC2= Ambient P=100.4kPa, Tair=18.8C, Tdew=11.5C Zero Air at 1625psi, AMP CA04119 524.77 at 1275 Tdewspan=16.00 CO2 zero 0.9374 -> .9374 Offset: .2ppm CO2 span 1.0234 -> 1.0295 Offset: -3.97ppm H2O zero 0.8995 -> .9003 Offset: 4.9ppm H2O span 1.0334 -> 1.0369 Offset: -.06ppm Notes: Setting the CO2 span to 524.77ppm seemed to force the value to ~524.85 instead of 524.77. 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. |

I swapped the desiccant bottle refilling it with silica gel desiccant. The humidity didn't change and hopefully will go down. Swap with regular dri-rite at calibration next time. |

Used our 7550 box 0674 instead on the AMP loaner used previously. I think this IRGA is okay. |
