Summary: Reinstall of the Vaisala CO2 soil profile, Two thermocouples not working.
Sherman 2014-01-29 I arrived about 9:30 with Patty. It was overcast and mild with little to no wind. No change in field conditions from last week. We reinstalled the Vaisala CO2 profiles. We traded a couple of probes with the Tonzi profiles. Tonzi got a couple of 3% probes and Sherman got a couple of 1% probes. Sherman Set A to the west of the data logger box got: 2cm, sn Z2720014, 1%, data logger channel 1 8cm, sn F4960019, 3%, data logger channel 2 16cm, sn G0150035, 3%, data logger channel 3 Sherman Set B to the east of the data logger box got: 2cm, sn Z2720011, 1%, data logger channel 4 8cm, sn F4960018, 3%, data logger channel 5 16cm, sn G0150037, 3%, data logger channel 6 Thermocouple #6 was replaced. PVC enclosure #5 was replaced due to missing screen. PVC enclosure #1 was missing its screen. PVC enclosure #6 had its screen re-glued in the field. We did not put the pipe insulation on the PVC tubes where they are above ground. This might still be done. We put new U-shaped fittings on the top of the tubes so that the opening is pointing down. The existing rubber plugs don’t fit the new fittings well. We should cut some pipe inserts to make a better fit. When all was done Thermocouple #4 and #5 were not reading. The CO2 mV readings were in reasonable ranges but the pattern didn’t seem to match the depth profile. The soil around the tubes was disturbed so we decided to let them site a week before worrying about the readings. |
