When: Sept 5th, 2002 D248 Trip Purpose: check 3 flux systems and download data, soil moisture probe reading, dendrometer reading, finish 3 A/Ci curves for oak leaf at Tonzi Ranch, Overall: All three flux systems running great last week. Nancy’s datalogger 5 back to normal last week after replaced the battery. Jianwu’s soil CO2 sensor work good. Lot of trees have more than half of the leaves turned brown, some small trees have more than 80% leaves turned brown. Dendrometer reading at 1:35 pm
Soil moisture probe reading:
Tower Flux system: Fence and sonic program OK. PV reading 14.3, 16.3, 2.2 at 12:45pm with fully charged battery. After download data, reboot pc, gillsonic output as follows;
Floor Flux system: Fence and flux running OK. PV reading 13.9, 16.3 and 1.9 around 11:30 am
