Tonzi: 2012-05-30 09:30:00 (DOY 151)
Author: Siyan Ma
Others: Martin, Nhat
Summary: Grasses are senescent, tried swapping Floor IRGA but new IRGA had bad water, well batteries bad, could not collect Vaira soil CO2 data.
When: Date: 5/30/2012 , Day: 151
, Watch Time: 9:30 am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Martin, Nhat
Weather: clear, sunny
Phenology: 90% of grasses were senescent at Vaira, 70% at
Tonzil.
Summary
- checked and downloaded data at Tower, Floor, and Vaira
- Tried swapping Li-7500 (#35) at TZ Floor site, but the
H2O channel of #35 didn’t work this time. #35 was taken back to the lab
for check.
- Calibrated Li-800 in the field.
- Collected grass samples for biomass
- Measure midday leaf water potential: ~-10 bar for oak
leaf; <-2 bar for pine needles
- Read dendrometers
- Measured soil moisture (with Martin and Nhant’s help)
- Didn’t get good reading for groundwater well. Probably
the battery was dead.
Vaira_Grass Site
- Fence and gate power: was not
on 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
- Check the fans of air temp. and relative humidity sensors
at Vaira. YES!
- Check MD-9 system connections YES!
- Check CR23X with two multiplexers
However, still can not talk to the
datalogger of soil CO2 profiles.
- 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 YES!
- check the fans of air temp. and relative humidity sensors
on the tower and the floor. YES!
- Put Tram back to the field. Working well.
- Check rain gage, make sure not clogged. YES!
- Check calibration cylinders;
CO2 - psig; flow -
psi; 421.63 ppm.
N2 - psig; flow -
psi.
Is the pump running YES!
Before zero
After Zero
Before Span
After Span
- 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.)
- downloading data YES!
- 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!
