Hisashi, Kyoko and I arrived at about 10:00. It was mild, overcast and still. It kind of felt like the world was holding its breath waiting for something. The pond has come up to about 2/3 full. There were a few small puddles in the road. The trees have full leaves now but still light green â€“ midday water potential next time. There are some flowers around.

I collected data and Hisashi and Kyoko did soil moisture and well measurements. I found the missing data from several weeks ago for the IRT and co2 profile systems. But the IRT hasnâ€™t sent any new data and I didnâ€™t discover this until I got home and started to put data away. Also the ground IRT was out of its mount again but still pointed at the ground.

I added a below canopy PAR sensor sn 110340 to the zcam-2 post. I might have moved the z-cam a tiny bit. The PAR sensor is connected the Floor Met CR23X. I downloaded its data and uploaded a new program.

I collected data from the FD chambers but did not clear their memory. Power was okay here now that I fixed the loose wire last time.

I made some more measurements of FLIR related stuff for Miriam. The IRTs pointed at the tree were misaligned again. I realigned them and tried to tighten the mount.

I serviced the z-cams. Looks like a cow got inside the fence around the Floor tower and leaned on z-cam 3 â€“ it was bent to the southwest. I straightened it up again but there may be some bad (unusual) photos in this batch. In putting the z-cam photos away, I also notice that the times for the z-cam 1 and 2 seem to be about two hours early. Probably something wrong in the new program on the CR6 â€“ need to check it next time.

I read the DBH gauges. Cluster tree 8 has died. I removed the two denrometer bands but left the metal id tags. I installed the Vernier scale band on Tree 5 that has been without a band for a long while. The DBH for Tree 5 today is 40.0cm. Another small tree (tag# ) near Tree 8 has also died recently, two others towards the tower died a while back, one by the z-cam and one by the tower guy wires have also died. So six trees all in the same area in the last few years.

We left at about 13:00
