Summary: Regular data download and site maintenance

Dennis and I arrived at ~14:35 PST. It was sunny and getting hot with no breeze. As we drove to the tower, we noticed a lot of old plants were knocked down by windthrows. The staff gauge reads 52cm at 14:56 PST. Dennis collected water samples for the upcoming school fieldtrip.

At the tower, I dowloaded MET, GHG, and camera data. Dennis cleaned MET and flux sensors. The LI-7700 reservoir was almost empty, and we refilled it.

The clock on for flux sensors was ~1.5 min behind; I stopped logging, resynced the clock, and restarted logging.

7500 read: 446ppm CO2, 579mmol/m3 H2O, 28.8 C, 101.6kPa, 95SS --96 after cleaning
7700 read: 2.2ppm CH4, 49RSSI – 80 after cleaning

Dennis measured compensated surface water conductivity.
Surface - 797 uS, 11.7C

We left the field at around 15:00 PST.
