Tonzi

We arrived around 10:30. It was sunny and warm. There were pock marks in the dust and water spots on the camera windows like there had been a tiny bit of rain.

I downloaded Licor GHG data at Tonzi floor. There were no summary files. When the LI-7550 clock said 10:00, I changed it to 10:04.
CO2 409.9
H2O 578.9
P 98.9
T 29.1
SS 99.6 --> 101.6 after cleaning

I downloaded Licor GHG data at Tonzi tower. There were no summary files.
CO2 408.3
H2O 588.7
P 98.9
T 27.7
SS 87.2

I also collected tower met data (data starts 2017-08-17 ~20:00, so we lost about 12 hours of data), soilco2 data, 2 fmet data tables, swapped camera cards for 3 zcams and the phenocam.

Joe downloaded soil moisture and well data. He also brought 3 compressed gas cylinders back to the lab--pressure bomb cylinder, CO2 calibration gas cylinders?

Joe installed a plywood interior panel in the tower met datalogger enclosure box, moved the AM16/32 and a CR1000 to the panel. I re-wired the CR23X sensors to the CR1000 and left the AM16/32 sensors wired in place. I uploaded a new CR1000 program: TZ_tmet_20170825.CR1.

Joe removed some sensors at the tower: HMP60 (sn L2310711), NR-Lite (sn 990351), Rotating shadow band (sn 060868), and pyranometer (sn 996981). Joe also replaced the incoming PAR sensor (sn 010159 came down, sn 010164 went up)

Joe installed 3 SRS NDVI sensors on the tower:
NDVI up/hemispherical: sn 2046503398
NDVI down/hemispherical: sn 1066703767
NDVI down/field-stop grass: sn 943103015

I removed the 9 Vaisala soil CO2 probes and brought them back to the lab for calibration:
sn K1310102 - Open, -2 cm depth
sn Z2720015 - Open, -4 cm depth
sn K1340006 - Open, -8 cm depth
sn L2010069 - Tree1, -2 cm depth
sn G0150035 - Tree1, -4 cm depth
sn G0150036 - Tree1, -8 cm depth
sn Z2720014 - Tree2, -2 cm depth
sn K1310104 - Tree2, -4 cm depth
sn F4960020 - Tree2, -8 cm depth

We left around 15:30.
