| LI-7500A 75H-2514 | 2022-03-09 | Lab none | Maintenance | Lab none | We ran zero air through this sensor today. The CO2 zero was fine at 1.21 ppm. The H2O zero was large at -26.8 mmol/m3 (previous H2O zero from last week had a +30.2 mmol/m3 offsets). In addition, the H2O zero changed depending on the orientation of the sensor. When laying on the bench, it was around -20 mmol/m3. When the top of the sensor was propped up slightly, the offset jumped to around -10 mmol/m3 and stayed steady. When we laid the sensor down again, the offset dropped to -20 mmol/m3 again. Joe didn't hear anything change inside the sensor when we were moving it around. We decided to change the internal chemicals. The old chemicals seemed ok. We flushed out the headspace with zero air before sealing it up again. I'll let it run on the bench for a few days before calibrating it again. |

| HMP155 R0360206 | 2022-03-01 | West Pond RH & Temp | Removed | Lab none | Removed from WP and brought back to the lab for further inspection. RH seemed ok but AirT was consistently NAN. It was replaced by HMP155 sn T2820183 the following week. |
| BF3 26/8 | 2004-07-24 | Lab none | Installed | Vaira PAR Sensor Diffuse | This looks like a likely install date - major data logger rewiring, first data in the data base. |
| LI-7500A 75H-2514 | 2022-03-03 | Lab | Calibration | Lab | Last calibration: 2022-01-11 AGC=100 SDM= DAC1= DAC2= Ambient P=99.99kPa, Tair=23.1C, Tdew=9.47C Zero Air at 925psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00 CO2 zero 0.9049 -> .9044 Offset: -2.15ppm CO2 span 1.0047 -> 1.0101 Offset: -3.55ppm H2O zero 0.8391 -> .8433 Offset: 30.2ppm H2O span 1.0087 -> 1.0199 Offset: -.25ppm Notes: Large positive H2O zero. Not really sure why it's difficult to get a good calibration. Is the sensor changing that much between calibrations (even though it's just been sitting in the lab)? Or is there something inconsistent about my calibration method? |
| LI-7500A 75H-2667 | 2022-03-02 | Lab | Calibration | Lab | Last calibration: 2021-09-29 AGC=100 SDM= DAC1= DAC2= Ambient P=100.5kPa, Tair=24.3C, Tdew=9.1C Zero Air at 950psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00 CO2 zero 0.9411 -> .9412 Offset: .2ppm CO2 span 1.0174 -> 1.0171 Offset: .36ppm H2O zero 0.8413 -> .841 Offset: -2.1ppm H2O span 1.0281 -> 1.0180 Offset: .21ppm Notes: |

The H2O span looked stable after 12-15 minutes, but I waited for 30+ min to be sure. |
| LI-610 DPG478B | 2022-02-28 | Loaned none | Returned | Lab none | Returned from Katerina back to us. There is an issue with the flow rate and it doesn't seem to go above 100 cc/min. There's enough water in the reservoirs and the condenser seems to be doing its job. I tried swapping out the internal air filter with a brand new one (borrowed from the UCSC kit), but that didn't make a difference. I don't think the rate was diminishing over time, so it makes sense that the internal air filter was fine.
Probably the problem is with the air pump diaphragm. The manual says that "A pump that is functioning normally will generally output a pressure of 450 to 600 mb, when measured at the TO CONDENSER port." I'm not sure how to measure that pressure (with something like a tire pressure gauge?) but I should probably check that before taking the pump apart. I changed the air pump diaphragm following the instructions in the manual and all seems well. |

| HMP155 T2820180 | 2021-11-23 | Lab none | Installed | Mayberry RH & Temp | Installed on the MB tower to replace HMP45 sn U2120013 which was drifting. It was installed with a new shield and aspirated with a 12V fan. The cable on this sensor says "sn T2820183", which is different than the actual sn of the sensor, so I crossed out sn on the cable to avoid confusion. |
| PQS 1 140454 | 2022-02-02 | Gilbert Tract PAR Sensor Incoming | Removed | Lab none | Removed from Gilbert Tract due to nighttime negative values. Replaced by sn 990031 last used at East End under canopy PAR |
| CS450 20010026 | 2022-02-02 | Gilbert Tract Water Level | Removed | Lab none | Removed from Gilbert Tract as its measurements are now redundant with the HYDROS21 water level sensor. |
| PAR-LITE 990031 | 2022-02-02 | East End PAR Sensor Undercanopy C | Moved | Gilbert Tract PAR Sensor Incoming | Removed from lower location south of the tower at East End. This sensor was disconnected from the data logger two weeks before. This sensor was moved to GT to replace the incoming PAR there that was having negative values at night. |

| HMP45A U2120013 | 2022-01-19 | Lab none | Tested | Lab none | Ran for a week on the lab bench next to an HMP155; both sensors were aspirated with a plug-in fan. I didn't see any drifting over the week, but still, probably don't want to use this sensor except as a last resort. |
| KD140SX-UFBS 11ZV0M0836 | 2022-01-14 | Lab none | Tested | Lab none | This panel has totally crack glass and two big divots. I tested it outside on a clear day. Data from the Delta says max SWin at this time of year is around 500W. Specs on the back say 6.3A at 800W. I got 3.4A. If you do the ratio you get 3.9A at 500W. As tested I did not have an unobstructed view of the sky and cracks in the glass but no shadows on the panel and a reasonable angle. So maybe worth resealing. Use Qsil 216: http://americansolarsupply.com/stores.html#!/QSil-216-Encapsulant/c/12380606/offset=0&sort=normal |
| WM 1590 153804 | 2022-01-13 | Lab none | Tested | Lab none | This sonic was giving bad SOS analog output at Mayberry after a bunch or messy power cycles. Today in the lab the digital SOS was 350m/s at 34% humidity and 102.5kPa and 25C. Sonic temp reading about 5C high - seem too much with high pressure and low humidity. I check the settings and the fourth analog output that should be SOS was set to Status (good is high, bad is low) which makes sense with the data we were seeing. I reset the fourth Analog output to SOS, saved the config. All winds were reading zero in the lab. I check the SOS output on the calibration Licor box and it read 350, same as the digital. Might need to do an inter-comparison before I trust the SOS. |
| PAR-LITE 040411 | 2021-12-14 | East End PAR Sensor Diffuse | Removed | Lab none | Removed dfPAR apparatus because the motor was not working. I brought it back to the lab to replace the motor. |

I took this sensor off from BA on 1/2/2022 to calibrate again and replaced it with sn75H-2176. This time though the CO2 values were very close, so maybe the problem was actually with sn 0035, not this sensor. However, during this calibration the CO2 span offset was 3.73ppm, which is larger than usual. There was also a large H2O zero offset of -15.1 mmol/m3. I thought about changing its chemicals, but they were just changed a year ago so they're probably ok. I will calibrate it again next week to check. |
| JAZ-EL350 JAZA2903 | 2022-01-11 | Lab none | Adjusted | Lab none | I changed the time from 12:42 to 11:50 to match my computer time. I'm not sure if the clock is drifting or if we set it to PDT in the past. We should keep the spectrometer clock on PST to match the rest of your data. Probably need to check the sensor clock every few months. |
| PA-II-SD 84f3ebd5ffb1 | 2021-12-13 | Lab none | Maintenance | Lab none | This sensor had some corrosion on one of the power connectors inside the sensor (it got rained on after the BC tower fell over), so Joe bypassed it by attaching one long mini-USB-to-USB cable. The clock was also ahead by one day. I brought the sensor home to connect to my home wifi for a few hours for the clock to automatically sync with the network. I checked the data files on the card and the timestamps were good. |
| eosFD FD20180067 | 2022-01-02 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from BC underneath the tower and brought back to the lab for testing. It was 1/2 submerged under water starting 2021-12-25, and Tyler put it on the lower boardwalk on 2021-12-29. |
