Summary: Need new tank for water potetial, PC at Vaira crashed - restarted, maybe need fan for box, swapped LI7500 at TZ Tower and Vaira.


Pond When: Date: 7/6/2011 , Day: 187 , Watch Time: 11:00 am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: hot
Phenology: Grasses completely turned into yellow, but some green grass still in the lower dry spot by the gate; green oak leaves

Tonzi

Vaira:

Little bit of green a bottom of hill

Summary
1. Tank for water potential measurement needs to be changed since midday leaf water potential of oak leaf < -25 bar; pin needle=-20 bar.
2. PC at Vaira showed “Reboot failure” when I got there. This caused 3 day data missing. PC worked well after I reboot it again. Should we replace a PC next visiting‌ The site was very hot. The fan in PC was on all the time, but I didn’t hear any sound from the fan on the enclosure.
3. checked and downloaded data at Tower, Floor, and Vaira
4. Swapped Li-7500 at TZ Tower and Vaira.
5. Calibrated Li-800 in the field.
6. Collected samples of aboveground dry biomass (400cm2 × 4), oak leaves and pin needles
7. Read dendrometers
8. Measured soil moisture
9. Measure groundwater well:

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: 13.0 v; 9.3 amps; 3.8 amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

Vaira Gill sonic plots screen before IRGA swap
  1. downloading data YES!
  2. swap Li-7500: remove #418; install #73.

Vaira Gill sonic plots screen after IRGA swap
  1. Check the fans of air temp. and relative humidity sensors at Vaira. YES!
  2. Check MD-9 system connections YES!
  3. Check CR23X with two multiplexers

Screen shot of Vaira data logger table
  1. Check levels of Radiation sensors, clear up surfaces. YES!
  2. Check rain gage, make sure not clogged. YES!
  3. Closed gate and set up fence. YES!

Tonzi_Tower Site

  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; 0.0 amps; - amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

Tower Gill sonic plots screen before downloading data
  1. downloading data YES!
  2. swap Li-7500: remove #41; install #1594.
  3. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  4. Check rain gage, make sure not clogged. YES!
  5. Check calibration cylinders;

CO2 1000 psig; flow 20 psi; 384.08 ppm.
N2 2000 psig; flow 20 psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ YES.
