When: Date: 3/28/2007 , Day: 87 , Watch Time: 9:30am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Xingyuan, and Youngyrle
Weather: clear, chilly, windy,
Phenology: oak tree leaves come out, 90%. Xingyuan said that tree leaves start coming out on the Monday of last week and more last Sunday. Grasses grew a lot during the past two weeks. Vaira’s grass start seeding, 20%.
Summary

1. EC systems worked well at the three sites and data are downloaded, but see a error message window at Vaira site.
2. swap Li-7500 at Vaira and Tonzi Tower,
3. grass sample for LAI and phenology in Tower and Vaira, oak branches for N
4. measure soil moisture
5. most of dendrometers are out of range. Should we replace them‌
6. Youngyrle took care of measurements of spectrometer
7. Xingyuan went to Tonzi for setting up sapflow measurements.
