Day 4

Like Day 3 but cooler.

The Tonzi Floor site still spun like a top.

W 0.220 0.233
U -0.520 0.306
V -0.110 -.463
T 21.864 1.653
Q 2.756 0.032
CO2 1.667 0.046

CR23X6 RH way too high

On CR10X7 there were some high temps e.g. C_Temp_1 and S_Temp_1 were 53.6 and 46.6 respectively

After gillsonic started up again

W 0.180 0.225
U 0.410 0.133
V 0.180 0.475
T 21.069 0.644
Q 2.751 0.016
CO2 1.603 0.014

Battery volts 13.4
Solar amps 7.3
Load amps 1.9

At 9:50 am on Day 4 I checked on the Tonzi Tower. It was frozen. Six flat lines, and did not respond to Alt-X. Climbed the tower and restarted the power supply, and everything was fine. Why did it freeze up? Checked on it later in the day and it was fine. As noted, when I last left the tower on Day 3, gillsonic was running and data were being collected.

On the tower:

Battery volts 12.8
Load amps 2.2-3.0 noisy upon rebooting the system
Solar amps 0.0

W 0.940 0.582
U 2.260 0.998

Q 2.521 0.024
CO2 1.107 0.014

Here is a short summary of Vaira: I noticed missing data from the time of Dennis’ last visit to 4:30 am the next morning, and from the time of my last visit likewise. I believe we both started gillsonic manually, causing the appearance that everything at Vaira was fine. I changed the PC208 call to gillsonic to 5 minutes in the course of deducing the problem. Always, always wait for PC208 to call gillsonic. Aside from that, everything at Vaira was fine. Here are the Vaira soil moisture measurements from Day 4:

Only found two soil moisture probes at Vaira. Are there more. Noted all six channels and everything looked good.
