Summary: Grass becoming senescent, tree leaves complete, swapped 7500s at Tower and Vaira, data not collected.
When: Date: 5/18/2012 , Day: 139
, Watch Time: 9:00am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear and sunny
Phenology: grass became senescent, 10% at Vaira, 20-30%
at Tonzi. Oak leaves fully extended.
Summary
- Swapped Li-7500 at Vaira and Tower
- Checked data at Tower, Floor, and Vaira Three EC
systems worked well. (Data were not downloaded this time because I forgot
bringing memory stick. I will do it next visiting.)
- Calibrate Li-800 in the field. It went well.
- Collected grass samples for LAI
- dendrometers
- soil moisture
- spectrometer at Vaira
- groundwater well

- Check data files. No missing data.
- swaping Li-7500 Analyzer. (Remove SN# 73 ;
install SN# 42 )
- Check the fans of air temp. and relative humidity sensors
at Vaira. Yes!
- Check MD-9 system connections; Yes!
- Check levels of Radiation sensors, clear up surfaces.
- Check rain gage, make sure not clogged.
- Closed gate and set up fence.

- check data files. No missing data.
- swaping Li-7500 Analyzer. (Remove SN# 0418 ;
install SN# 1549 )
- check the fans of air temp. and relative humidity sensors
on the tower and the floor. Yes.
- Check rain gage, make sure not clogged.
- Check calibration cylinders;
CO2 1250 psig;
flow 20 psi; 421.63 ppm.
N2 1700
psig; flow 20 psi.
Is the pump running Yes.
- close gate and set up fence.
Toniz_Floor Site
- Fence and gate power: 12 v.
- Panel and Batteries: 14.1 v; 11.2
amps; 1.7 amps.
- Reading from Gillsonic screen before downloading data.
(The value of H2O and CO2 should be in the range of
0 – 5 v.)
- check data files. No missing data.
- I was planning to swap Li-7500 Analyzer. However, I had to
swap it back because the CO2 channel of IRGA (#35) showed -0.0001. The
set of IRGA was newly calibrated by Li-cor, and it was working well when I
recalibrated in the lab on 5/17/2012.
- Check MD-9 system connections. Yes. All worked well.
- Close gate and set up fence.
