Summary: PRI sensors operational, reinstalled LI-820 but still some plumbing problem, Tower fence down - repaired, missing Tram data, swapped tower 7500.

2014-09-11

I arrived about 11am with Siyan. It was clear and hot with a little breeze from the west. Most of the trees here have brown leaves. Tonziâ€™s pond still has water. Last year the pond was almost dry in early November. There were a bunch of cows standing around the watering station.

I finished installing the Decagon PRI sensors. They ship with a default SDI address of zero, but the 23x cannot talk to a sensor with a zero address (apparently). I set the incoming sensor sn 759503109 SDI address to 1 in the lab and the reflected one sn 816903083 to SDI address 2. Both seemed to be working, but the PRI calculated with the initial readings was negative. Maybe that will change, or maybe the PRI of area of view is just zero right now.

I reinstalled the LI-820 sn CGA-556 in the co2 profile system. The 820 seemed to be okay, but the plumbing seemed to be having problems. The cal gasses dumped into the lowest inlet did not seem to be reaching the analyzer. It seemed like the solenoids were stuck open. I reloaded the 10x program and it looked like it was cycling the ports properly. I let it run and will try to troubleshoot it more next time.

Just before leaving I noticed the fence around the tower was down. A big section in the south east corner had been pulled free by cows and there was evidence of cow inside of the fence. I patched it as best I could, but it could use some more work and maybe we could put some flagging on it to make it more visible.

Looking at the data, the tram data was largely missing. Maybe the rename program is not working correctly.

We swapped the 7500 on the Tower - sn 0418 came off and sn 0976 went on.

I serviced the zcams. Cam 1 did not boot properly on the card at first. I ejected the card, unlocked it and relocked it. Then it worked.

Siyan did the standard fieldwork plus midday water potential.
