Summary: Beautiful day, Standard field work

When: Date: 3/23/2016 , Day: 83 , Watch Time: 9:00 am .

Where: Tonzi/Vaira Ranch

Who: Siyan, Joe

Weather: a beautiful spring day; clear, sunny

Phenology: oak leaves didnâ€™t look growing very much since they came out a couple of weeks ago. Maybe due to raining -> low temperatures. Grasses are growing fast, about 10 â€“ 20 cm high.

Summary

Swapped memory cards of CR1000s at three sites.
Joe fixed the cable of Vaira phenocam
Checked and downloaded met data from PC at Floor and Vaira.
Checked the soil CO2 probes at Tonzi and Vaira;
Read dendrometers
Measured soil moisture
Measured grass height and stem density
Measure groundwater well

Vaira_Grass Site

no Phenocam images due to broken cable. Joe fixed it.
Swapped the memory cards of CR1000.
Checked the fans of air temp and relative humidity sensors at Vaira. YES!
Downloaded met and soil CO2 profile data:

Checked levels of Radiation sensors, clear up surfaces.YES!
Checked rain gage, make sure not clogged. YES!
Closed gate and set up fence. YES!

Tonzi_Tower Site

Fence and gate power: 12 v. (found and fixed the broken part)
No tram data; it is about to remove.
swapped the memory cards of CR1000.
download Phenocam images. (Joe did.)
checked the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
Checked rain gage, make sure not clogged. YES!
CO2 profile system is under construction.

8. closed gate and set up fence. YES!

Toniz_Floor Site

Fence and gate power: 12 v.
Swapped the memory cards of CR1000.

downloaded met data from PC. YES!

CR23X3 â€“ floor-Met;

CR23X6 â€“ tower-Met;

CR10X2 â€“ floor-Met;

CR23X5 â€“ soil CO₂ profile: 3 probes at Open site had no readings because the power switch was broken; Joe took it back to the lab.

Closed gate and set up fence. YES!
