Summary: First real rain but not much, New tenant at Tonzi's house, Removed OSU SP1 tipping bucket for lab experiments. Grass is sprouting everywhere

Tonzi
2020-12-18

I arrived at about 9:30. It was clear and sunny and cool â€“ I saw the fog lifting as I drove in from Sacramento. There had been the first real rain a couple days ago. The ground was so dry that it just sucked up all the rain. There were a couple of puddles on the road but otherwise the ground was still hard and almost dry in sunny spots. Grass has sprouted everywhere giving the ground a green tint.

I met the new tenant and his black Labrador now living in Mr Tonziâ€™s house. The man had an idea of the science we are pursuing and his wife is related to the SMAP soil moisture project in some way. I gave him my contact information â€“ not sure Iâ€™ll hear from him or not.

The Tower seemed to be running fine. Most of the data was on the Tower computer â€“ cycling the power on the IRT CR1000 reestablished the radio connection and got that data up to date. The antenna was okay this time. I guess Iâ€™ll have to use the loner cable and get the antenna in a better spot.

The Tower 7500 read: 434.3ppm CO2, 351.9mmol/m3 H2O, 8.7C, 100.1kPa, 98.8SS

I forgot to check the power connections on the Tower top CR1000 but there was no missing data this time. Maybe cycling its power last time fixed the issue.

I collected the Floor data, the other data loggers, serviced the z-cams and the FD chambers. I did the Moisture Point readings, well depth and DBH readings. The Moisture Point probe near the Floor tower was loose in the ground and moved up a few centimeters when I pulled the cap off.

The Floor 7500 read: 432.3ppm CO2, 379.5mmol/m3 H2O, 9.8C, 100.2kPa, 99.1SS

I removed the tipping bucket sn 48130-611 from the OSU SP1 system for experiments in the lab. I disconnected the cable inside the bucket so I didnâ€™t have to pull the cable out of the ground but that means we will have to add some wire in the lab to use it.

I left at about noon for Vaira
