Tonzi: 2015-01-21 10:45:00 (DOY 21)
Author: Joe Verfaillie
Others: Siyan

Summary: Reinstalled CO2 profile system with new CO2 tank, Removed downward LED head for repair, Swapped lowest HMP45, updated CR1000 OSs.

Tonzi
2015-01-21

I arrived about 10:45 with Siyan. It was cool and sunny with little to no wind. The pond was nearly half full and the grass looks healthy. We saw Tonziâ€™s granddaughter and husband on the way in and then again later. The road looks like it has had more traffic than usual and they are cutting wood off to the west.

I installed a new tank of CO2 from the profile system. I installed the LI-820 sn CGA-556 and got the co2 profile system running. The level two tubing was disconnected â€“ I reconnected it. I calibrated the LI-820. Last cal was 2014-12-09. The N2 tank was 1350psi and the CO2 tank was 1700psi at 405ppm CO2. Zero was more than 50ppm low. Span was 25ppm low.

There was condensation in both the BF5 and pyranometer.

The LED sensor has not been working because the downward head was full of water. I think it dribbled in on the wire. I removed it from repair in the lab.

The bird spike on the sonic were loose. I fixed them.

The Tram was running.

I replaced the lowest HMP45 sensor in the RH and Temp profile. sn T0720012 came off and sn U3030041 went on.

I serviced the z-cams.

I updated the OS on the CR1000s from v25 to v27.

The battery cover at the tower needed some love. I tightened the screws on it.

One small oak tree near the floor site fell down â€“ number 230 I think.
