Summary: System was put into low flow mode. Soil probes checked and may need replacement.
Returned to site and checked everything out. Cleaned radiometers, checked flow and filters. The system is running at 110 torr. The reading was about 2.2 ppb. I put the system in low flow mode and pressure changed to 159 torr and the reading was stilil about 2.2 ppb, so I am not seeing a bias with the low cell pressure. Fog was just burning off when I got to site. Humidity 100% The coarse grain filter was a bit damp. I tried to dry it off to improve flow, but that did not help. Checking system W: 0.24 U: -0.49 V: -6.2 T 7.3 Q: 1.97 C 1.851 CH4 2.2 All systems on scale Met P 102.8 Ta: 5.2 RH 101 Water p 0.17 Tsoil, sensors Tc1 at 2 and 8 cm, Tc2 at 16 and 32 and tc 16 at 32 cm are off scale. Not sure what saturated soil is doing. We may need to build and replace soil probes Methane sensor Tcel 16.6, P 112 tor, 16.61 microsec, 10 Hz Water table was about 70 cm by putting the ruler into the well and looking at where it is wet. |
