Portable Tower
We arrived at the high veg portable tower site at about 14:30 PDT. It was hot and sunny. Lots of wasps buzzing about. The water level was very high here. Tons of caterpillars about. There was a big dirt truck driving on the main N-S berm and making everything really dusty. I think it was filling potholes in the berm. Sara took water samples while I checked the tower and downloaded data. I also updated the 7500 firmware to 7.3.0.

Readings
CO2: 399 ppm (414after cleaning)
H2O: 300 mmol m-3 (355 after cleaning)
signal strength = 72.48% (78.15% after cleaning)
p = 101.6 kPa
t: 32.8 Â°C
sos = 350.9 m s-1
CH4: 2.03 ppm (after cleaning)
RSSI: 2% (71% after cleaning). Also checked that sprayer and spinner worked.
Topped off reservoir.

Didnâ€™t check Met.

Permanent Tower
We arrived about 15:00 PDT. Hot and sunny. Water level high. Sara took water samples and cleaned the radiometers while I checked the tower, updated the 7500 firmware to 7.3.0, and downloaded data. I also cleaned the Ameriflux sensors since the dirt truck was making things dusty.

Readings
CO2: 400 ppm (409 after cleaning)
H2O: 480 mmol m-3 (401 after cleaning)
signal strength = 98.79% (100.27% after cleaning)
p = 101.6 kPa
t: 30.7 Â°C
sos = 351.1 m s-1
CH4: 2.0 ppm
RSSI: 56% (70% after cleaning)

Met looked good.
