We arrived at 9:15. It was foggy, hazy, and cool, with a light breeze. There were bundles of willow and red-osier dogwood in the water by the water inlet.

I collect met, camera, and USB GHG data. We used the new field laptop, and I set up the met CR1000 as a new station. I couldn't remember the stardot IP address (and couldn't connect via StardotTools on the old or new laptop), so I did not update the stardot file names. The camera card seems to have the full set of photos, so there shouldn't be a problem with the camera.

Kyle cleaned the rad and EC sensors. The wash reservoir was empty, and Dennis refilled it. The LI-7700 wash settings were wrong, even though we thought we had corrected them 2017-11-30. It was set to wash every 30 min when RSSI dropped below 80%; I changed it to wash every 3 hours when the RSSI drops below 30%. I applied the settings, closed the LI-7700 software, restarted the software, and confirmed that the wash settings were still correct.

LI-7500 readings:
CO2 450 ppm --> 463 after cleaning
H2O 700 mmol/m3 --> 538 after cleaning
T 11.9 C --> 12.0 after cleaning
P 101.9 kPa --> 102.2 after cleaning
SS 8 --> 98.4 after cleaning

LI7700 readings:
CH4 3.3 ppm --> 3.3 after cleaning
RSSI 47 --> 78.7 after cleaning

We left at 9:45.
