Summary: Regular data download and site maintenance

Dennis and I arrived at ~13:05 PST. It was sunny and warm, but breezey. The path to the tower had lots of weeds. The staff gauge reads 59cm at 13:33 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, and wipped the camera lens. For the flux sensors, Dennis lowered the post with orginal location marked. The post was raised back to its original location after cleaning. The LI-7700 reservoir was 2/3 full, 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: 435ppm CO2, 538mmol/m3 H2O, 24.5 C, 101kPa, 109SS --109 after cleaning
7700 read: 2.1ppm CH4, 49RSSI – 72 after cleaning

Dennis measured compensated surface water conductivity.
Surface - 2564 uS, 16.9C

We left the field at around 13:40 PST.
