West Pond
2020-09-10

Daphne and I arrived at 13:25. It was overcast and warm, the sun an orange disk in the sky. AQI was about 100-130 at nearby stations. There was ash on the boardwalks and radiometers. This is an out-of-cycle visit. We are here today and Daphne will be off next week so we decided to do all the sites today. The inlet was not running and the water level is well below the staff gauge. Sheep are grazing on the levees.

I checked on the solar system. The batteries are like new and water levels are good. I cleared some of the vegetation around the panels and washed the panels which were really dirty.

Daphne collected the data.
The 7500 read: 415ppm CO2, 723mmol/m3 H2O, 21.1C, 101.6kPa, 96SS â€“ 101 after cleaning.
The 7700 read: 2.09ppm CH4, 47RSSI â€“ 73 after cleaning.
The 7700 wash and heater setting were on defaults from some reason. The wash settings were returned to 10sec spray and 30sec spin every 3hr below 30RSSI. The heater settings were returned to 5% between 18:00 and 09:00 if RSSI is under 30.

The willow trees near the tower are getting big again and could use some trimming.

We left at 13:55
