When: Date: 6/9/2009 , Day: 160 , Watch Time: 4:40am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: partially cloudy, not hot, and windy on the tower. (Saw Mr. Tonzi. He said that it hadn’t been got hot as it is supposed to be, like San Francisco weather. Lightning made night like a day during a night thunderstorm last week. He looked fine. He’s going to cut a falling tree, but he didn’t want to cut too much because he’d been lost some wood consumers. He doesn’t think the President can make that much money for the economics.)
Phenology: annual grasses died out, but broadleaf herbs were still green with yellow, purple followers

Tonzi: full moon, surface temp, little acorns, yellow needles

Vaira: patches of community

Summary

1. Measured pre-dawn leaf water potential of oak leaves and pine needles:

Oak leaves: ~ -7.0 bar
Pine needles: ~ -10.0 bar

1. Took Amax and A-Ci curves for oak and gray pine
2. Fixed problem of Rh on tower CR23X met datalogger (tz6): I didn’t connect 14L and 16L with a wire. Now,

1. Checked and downloaded data at Tower, Floor, and Vaira. The three systems worked well.
2. Calibrated Li-800 in the field
3. Sampled oak leaves and pine needles: pine needles looked more yellow. Probably more needles get senescent during the dry summer‌
4. dendrometers: tree DBH start decreasing!
5. measured soil moisture
6. took spectrum at Vaira
7. groundwater well: groundwater level looks increasing a little bit.
