When: Date: 2/27/2009 , Day: 58 , Watch Time: .
Where: Tonzi/Vaira Ranch
Who: Siyan, Joe, Dennis, Hideki, Gretchen
Weather: clear
Phenology: green grass, Mr. Tonzi’s pond had more water after good rains.
Summary

1. check BOOM at Vaira: Dennis’s GPS - north
2. checked and downloaded data from Tower, Floor, and Vaira
3. swapped Li-7500 at the three towers
4. calibrated Li-800 in the field. Bump reinstalled.
5. Joe installed gray panel for the phenology camera.
6. Joe installed “surface temperature” sensor on the tower. Tower met program is changed. Need to adapt to Flux processing program.
7. collected grass sample for LAI
8. read dendrometers
9. Dennis took measurements of soil moisture probes.
10. spectrometer
11. camera

Is the pump running‌ Fixed and reinstalled by Joe.
How to check the CO2 values‌ Click “Ports/Flags” button to see which ports or flags is setting high. Pressure should be less than ambient value. When Flag 8 is high, it may indicate that RRR’s battery is low.

1. close gate and set up fence. YES!
