Author: Siyan Ma
Others: Joe, Daphne

Summary: Standard fieldwork, spectrum and litter collections, upgraded soil co2 system, upgraded Tonzi tower met CR1000 OS

When: Date: 9/21/2017 , Watch Time: 9:30 am .

Where: Tonzi/Vaira Ranch

Who: Siyan, Daphne, Joe

Weather: sunny

Phenology: The little pond dried out; much less green leaves on the tree.

Summary

Swapped memory stick of Licor 7550 at three sites.
Siyan checked and downloaded phenocam images and met data from PC at Vaira; Daphne did at Tonzi.
Joe re-installed soil CO2 probes at Vaira, 3 locations and 4 depths at each location
Read dendrometers
Measured soil moisture
Measure groundwater well and download GlobalWater data
Measure midday water potential of oak leaves
Collect grass litter samples
Spectrum of Vaira grassland
Download IRT data (Daphne)

Tower & Floor (Daphne)

We arrived at Tonzi around 12:00. It was partly cloudy and cool, with fluffy/stormy clouds to the N and E.

I updated the Tonzi tower met CR1000 sn 50890 OS from version 27 to version 31.08. I reset the IP address to 192.168.2.100, subnet to 255.255.255.0, IP Gateway to 192.168.2.1, and enabled FTP with user Tower and pw biomet.

I downloaded tower met, tower GHG, floor met/sm, floor GHG, soil CO2 data, and IRT data. At the soil CO2 CR23X, I synced the clock: when station was 1/7/2020 11:21:28, I changed it to 9/21/2017 12:08:26. I also swapped zcam cards.

I cleaned the radiation and flux sensors at the tower and the floor. When I collected tower GHG, a fresh USB stick that just came from Vaira was not recognized by the LI-7550, so I emptied and re-used the current USB.

Tower LI-7500 readings:
CO2 397.7
H2O 368.9
T 17.9
P 98.8
SS 87.5 --> 88.5 after cleaning

Floor LI-7500 readings:
CO2 403.9
H2O 335.4
T 22.5
P 98.9
SS 96.3 --> 99.9

We left Tonzi at 14:20 and stopped at Vaira to pick up Joe before heading home.
