Author: Siyan Ma
Others: Joe
Summary: Standard fieldwork, midday water potential, CO2 profile pump down, HMP45 fan down at VR, Floor CR100 data not recorded - winflux okay
When: Date: 7/11/2013, Day: 192 ,
Watch Time: 9:10 am.
Where: Tonzi/Vaira Ranch
Who: Siyan, Joe
Weather: clear, sunny, nice breeze, getting drier
Phenology: yellow grasses; Joe noticed that some oak
trees start to have yellow leaves; a few of small trees along the road in Tonzi
Ranch to the tower; they are located on the area with lots of rocks.
Summary
- Joe checked and downloaded data from PC at Tower, Floor,
and Vaira.
- Joe swapped memory cards of CR1000s at three sites and
found the card didn’t work properly at Floor site. I learned the lessons
again.
- Fan of Hmp45 at Vaira was not working. It will be
replaced next visiting.
- Pump of the CO2 profile system was dead. It will be
replaced next visiting.
- Measured Midday water potential.
- 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 (Joe).
- Check the fans of air temp and relative humidity sensors
at Vaira. No!
- Check levels of Radiation sensors, clear up surfaces.YES!
- Check rain gage, make sure not clogged. YES!
- Closed gate and set up fence. YES!
 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 – 5 v.)
 - downloading data from PC. (Joe)
- Swapped the memory cards of CR1000. (Joe)
- check the fans of air temp. and relative humidity sensors
on the tower and the floor. (Joe)
- Check rain gage, make sure not clogged. YES!
- CO2 profile system: Is the pump running‌ No!
- close gate and set up fence. YES!
Toniz_Floor Site
- Fence and gate power: 12
v.
- Panel and Batteries: - v;
- amps; - amps. (about 7:00 am local time)
- Reading from Gillsonic screen before downloading data.
(The value of H2O and CO2 should be in the range of
0 – 5 v.) (Joe)
- downloading data from PC. (Joe)
- Swapped the memory cards of CR1000. Joe found
the card didn’t work properly at Floor site. I learned the lessons again:
be much more careful when swapping the card! (1) push the button on CR1000
first; wait for green LED light on; then push the card out; (2) after push
a new card in, should see the red LED light blink fast. It means the
datalogger is checking and formatting the card. It may take a while to
finish this process. I should come back to see the red LED light blink in
a slower motion. It means the card starts recording data. (3) Always
good to double check the card status by connecting CR1000 from the PC.
- Check MD-9 system connections YES!
CR23X3 – floor-Met
CR23X6 – tower-Met
CR10X2 – floor-Met
Soil CO2 profile: CR23X5
– soil CO2 profile
 - Close gate and set up fence. YES!
