Arrived 8.30 am PST
Conditions: cool (ground dew), sunny, high cirrus clouds, calm.
Alfalfa field mostly consists of weeds (grass, nettles).
Deep puddles along the road.

JV downloaded data and synced clock, CAMCARD, Met, Soil CO2 data.

P: 102.2
rssi: 103.0
Set clock: 8:43 to 8:39

SC took veg height measurements.
Li6400 had a broken O-ring (no soil resp. measurements taken).
AV took LAI measurements using LAI 2200.
SC did clip plots (veg harvested).

Forgot to swap battery cables and split loom to expose wires.
