On 5/3/01 d123 9:00 arrived at Tonzi Ranch, strong wind, hot and low RH. Forgot bring the tripod, can not do the Li-Cor 6400 measurements.
Download the floor system data, including raw, met, soil and sap flow data. system running properly. took 8 grass LAI samples (4 under tress and 4 open space).
Photovoltaic controller at the floor system reading was 11.7V, 1.4 A and 2.6 A. The voltage is kind of low, I noticed that solar panels are shaded before 11:00 PST and after 3:00 pm. Only 4 hr for those panel got the sun light. I Talked to Ted last Fri when we were at the field, he said we should move the panel 20 feet south.
Vaira Ranch Arrive at 11:20 PST.
Download the raw data, met and soil data. All instruments running properly.
