Summary: Swapped 7500s at all towers, Jianwu's batteries swapped, Nancy's data logger 5 needs new battery, three ACi curves
When: Aug. 15, 2002 D227 Trip Purpose: check 3 flux systems and download data, soil moisture probe reading, dendrometer reading, A/Ci curve for oak leaf at Tonzi Ranch, replaced all the li-cor 7500, clean all the solar panels. Overall: All flux systems and other instruments were running great last week. Tonzi Ranch: arrived at 9:00. Jianwu’s two batteries dead, replaced them with two fully charged ones at 10:10. Nancy’s data-logger #5 dead, need a battery. I finished 3 A/Ci curves for oak leaves. Dendrometer reading:
Comparing with previous dendrometer reading, trees stem are shrinking very fast now. Soil moisture probe reading:
Floor system: Fence and flux system running good. Replaced li-cor 7500 sn 0065 came off and sn 0073 went on. PV reading 13.6, 13.7 and 1.7 fully charged batteries at 10:45am. Gillsonic ourputs after reboot laptop;
Tower system: Fence and flux system running good. PV reading 13.6, 9.1, and 2.7 at 1:15 pm: replaced licor 7500 sn 0041 came off and sn 0035 went on. Gillsonic output after reboot the laptop.
Vaira Ranch: arrived at 15:10. Fence Ok, flux system also running great last week. PV reading 13.3, 6.1, and 3.1 at 15:30 with fully charged battery. Replaced li-cor 7500 sn 0042 came off and sn 0418 went on ( brand new !!). Cleaned solar panels. Soil moisture probe reading (see above). Sonic outputs looks Ok after finished all the tasks, see below;
