Summary: Leaf out starting, swapped 7500s on Tower and Floor, No met data collected at Vaira due to dead battery

When: Date: 3/4/2014 , Day: 62 , Watch Time: 9:30 am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: cloudy
Phenology: (1) the oak tree near Mr.Tonziâ€™s house had leaves out; ~20 days earlier than multi-year average; another tree near Tower had leaves out, too; not yet the majority of oak trees, though. (2) Grassland turned into green. (3) standing water at Tonzi.

Summary

Checked and downloaded data from PC at Tower, Floor, and Vaira. Vairaâ€™s met data and soil CO2 profile data were not downloaded because the laptop had dead battery (it was plugged in when I took it in the lab.).
Swapped memory cards of CR1000s at three sites.
Swapped Li-7500 at Tower and Floor sites.
Calibrated CO2 profile system: did zero but not span because CO2 tank was empty.
Read dendrometers
Measured soil moisture
Measure groundwater well:

Vaira_Grass Site

Fence and gate power: 12 v.
Panel and Batteries: - v; - amps; - amps.
Swapped the memory cards of CR1000.
Check the fans of air temp and relative humidity sensors at Vaira. YES!
Vairaâ€™s met data and soil CO2 profile data were not downloaded because the laptop had dead battery
Check levels of Radiation sensors, clear up surfaces.YES!
Check rain gage, make sure not clogged. YES!
Closed gate and set up fence. YES!
Grass litter height (cm): 3.5

Tonzi_Tower Site

Fence and gate power: 12 v.
Panel and Batteries: - v; - amps; - amps.
Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 â€“ 5 v.)

downloaded data from PC and swapped the memory cards of CR1000.
Swapped Li-7500s. sn 0035 off sn 0073.
check the fans of air temp. and relative humidity sensors on the tower and the floor. YES! A wire came out of the white wire connector. Reconnect directly between wires (+). It sounded working, but not very noisy. Maybe need replace next visit.
Check rain gage, make sure not clogged. YES!
Check calibration cylinders;

CO2 tank	404.02ppm	0	18psi
N2		900	10

Is the pump runningâ€Œ YES!
Calibration: did zero but not span because CO2 tank was empty.

close gate and set up fence. YES!
