When: Date: 8/6/2008 , Day: 219 , Watch Time: 9:30am .
Where: Tonzi/Vaira Ranch
Who: Siyan, DDB
Weather: clear, not too hot, see storm cloud far away, nice breeze
Phenology: dry yellow grasses, oak leaves start turning into yellow (Mr. Tonzi thinks so. He also remembered that 1975 was a very dry year. Grass needs 4in continuous rainfall to develop roots, around Oct. 15th)
Summary

1. DDB connected the second solar panel to the regular of the first one at Vaira.
2. DDB moved the thermalcouple sensor from sonic area to Li-7500 head.
3. DDB double checked the grounding of met datalogger at Vaira. Looks OK.
4. CO2 profile: DDB fixed the pump and manually calibrated Li-800 successfully. The communicating problem was solved by checking and reconnecting two ends of cable connections.
5. Tram system’s battery was dead, voltage 3.0. How to fix it‌ First, disconnect datalogger’s power; Second, set back to the charging station or swap a fully charged small battery; Third, put the whole set at the end opposite to the charging station. Reconnect datalogger’s power and see whether RRR works OK.
6. Ground water measurement: near floor site=28.7 feet; south tower = 33.6 feet; by road = 37.55 feet.
7. checked and downloaded data at Tower, Floor, and Vaira. EC systems worked well.
8. read dendrometers.
9. measured soil moisture probes.

Is the pump running‌ CO2 profile: DDB fixed the pump and manually calibrated Li-800 successfully. The communicating problem was solved by checking and reconnecting two ends of cable connections.
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.
