We arrived at approximately 12:45 PDT. It was warm with a mild breeze, about 22 C. They have planted the field and little sproutlings were popping up. Sara did spectral while I attended to the tower. I set the 7550 clock to what I thought was UTC but was really an hour ahead of UTC. I realized my mistake later and we returned at 3:50 PDT and set it correctly (and saw an awesome spider fight and a GIANT black widow it was worth the return trip). So there is a few hour block that is one hour ahead of UTC and the rest at UTC. Sorry Joe.

7500 readings:
CO2 = 390 ppm (400 after cleaning)
H2O = 620 mmol m-3 (530 after cleaning)
agc = 23 (after cleaning it was 20.5)
p = 102.25 kPa

7700 readings:
CH4 = 1.9 ppm (1.88 after cleaning)
RSSI = 13.3 (bumped to 62 after cleaning)
The reservoir was full, refilled to 100%.

MET looked good.
