Mark I A001911 | 2021-09-15 | Sherman Wetland Weather Station | Installed | Gilbert Tract Weather Station | Installed on the radiation boom pointing south |
HMP45AC U3030041 | 2021-12-13 | Lab none | Tested | Lab none | Tested this sensor against an HMP155 on the lab bench. Both sensors were aspirated. Temperature data is inconsistent, sometimes matching the HMP155 and sometimes not. Do not use this sensor. |
LI-7500A 75H-2514 | 2021-12-09 | Lab | Calibration | Lab | Last calibration: 2021-08-31 AGC=101 SDM= DAC1= DAC2= Ambient P=100.5kPa, Tair=25.2C, Tdew=5.04C Zero Air at 1100psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero 0.9046 -> .9048 Offset: .56ppm CO2 span 1.0082 -> 1.0101 Offset: -1.47ppm H2O zero 0.8399 -> .8413 Offset: 9.9ppm H2O span 1.0133 -> 1.0349 Offset: -.46ppm Notes: <100 psi left in the first zero air tank, but I did the zero anyways. The H2O value was climbing after I set the zeros, so I think that first tank was running out of air. I switched to a different zero air tank with psi=1700 to re-do the zero calibration. The offsets didn't change too much (<0.01 change in the calibration coefficient for CO2 Zero and H2O Zero). I then did the CO2 span and H2O span as usual. |
LI-7500A 75H-2669 | 2021-12-09 | Lab | Calibration | Lab | Last calibration: 2021-08-31 AGC=100.7 SDM= DAC1= DAC2= Ambient P=100.4kPa, Tair=25.6C, Tdew=6.06C Zero Air at 100psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero 0.9188 -> .9186 Offset: -.81ppm CO2 span 1.0127 -> 1.0133 Offset: -.02ppm H2O zero 0.9005 -> .9008 Offset: 2.1ppm H2O span 1.0086 -> 1.0123 Offset: -.09ppm Notes: Not much air left in the zero air tank, but the zero was stable for 2+ min after setting the zeros, so I feel comfortable the calibration was good. Initially forgot to save the new config, so re-opened the prev file from 2021-08-31, entered the 4 coefficients manually, and saved with today's date. |

AGC=100 SDM=0 DAC1=- DAC2=- Ambient P=99kPa, Tair=99C, Tdew=99C Licor at psi, Licor 750 at 99 Tdewspan=12 CO2 zero 0.957 -> 0.9182 Offset: 0ppm CO2 span 1.0075 -> 1.0 Offset: 0ppm H2O zero 0.7337 -> 0.8187 Offset: 0ppm H2O span 1.0078 -> 1.0094 Offset: 0ppm Notes: Factory calibration at Licor after replacement of chopper, detector and source. Unknown ambient conditions and offsets. This sensor was sent to Licor because its signal was noisy. Its parts are almost 20 years old so I asked to have it renovated. Licor said, "Inspected the unit and found it in operational condition. Replaced the chopper motor, the detector and the light source. Subjected the unit to environmental tests and calibration." Should be nearly as good as new. |

miniDOT 1221 | 2021-10-20 | Lab none | Tested | Lab none | This sensor was covered in barnacles, the copper screen was falling apart and there are nicks in the coating on the window. I cleaned up the sensor and tested it side by side with miniDot sn 931528. Both sensors were suspended in a bucket of water with a bubbler in the bottom. The sensors were out of the stream of bubbles. Ice was added to the water bringing its temperature down from 20C to 0C. Then the dissolved O2 was recorded by both sensor over about 24 hours as the water returned to room temperature. The two miniDots matched each other by better then 2%. And they matched the theoretical O2 saturation of the water at about 4%. This sensor had a quailty flag of about 0.84 whereas the newer, uncompromised sensor (sn 931528) had a quality flag on 1.03. I think I'll send a photo of the window coating and these notes to PME to get their take, but I think it's okay to return sn 1221 to service. |

miniDOT 1221 | 2021-09-02 | Mayberry DO Sensor D | Removed | Lab none | Removed from Mayberry because it had a bunch of barnacles growing on it, the copper screen was disintegrating and the coating on the window looked damage. Replaced by sn 899502 |
ML2x 139/052 | 2021-03-17 | Lab none | Calibration | Lab none | After looking at the data recorded from 2021-03-17 to 2021-10-06 it seemed that this probe was reading too low in the spring and too high in the fall. Most years the soil gets completely saturated in the spring and completely dry in the fall. If you take the max and min values from all years they are very similar. Min: 473mV STDEV=6.8mV, Max: 913mV STDEV 24.8. Then we can use these to scale this sensor's min and max with this year's data and we get Corrected (mV) = raw (mV) * 1.272 -187.73 And using the manual's default conversion values for mineral soil (0.05 and -5), the total conversion is: %m = mV * 0.636 + 4.39 |
