I arrived about 10:00 with Patty. It was clear, sunny and mild with a good breeze from the west. I did not notice any significant change in the overall site.

Portable Tower â€“ High Veg:
The water level was very low. Patty had a hard time getting a water sample in the vegetation. I serviced the tower.

The 7700 read: 1.96ppm CH4, 61.0 RSSI 72.9 after cleaning.
The 7500 read: 393ppm CO2, 710mmol/m3 H2O, 91.4SS, 100.68kPa, 21.77C

The clock on the 7550 was 10min ahead. I reset it from 9:36 to 9:26. I did not check the 7700 afterwards assuming it would reset as slave, but maybe I should have.

I cleaned otter prints of the solar panel.

Permanent Tower:
At the permanent tower, I installed a post for the Ameriflux inter-comparison next week. I only had one of the two rail fittings, so the second rail fitting will have to be installed next time.

Patty collected water samples and downloaded the data.

The 7700 read: 1.96ppm, 47.8 RSSI 70.0 after cleaning.
The 7500 read: 395.9ppm CO2, 734.4mmol/m3 H2O, 100.3SS, 100.3kPa, 23.37C

Met was okay, we downloaded the current program to make changes next time. The SE Forerunner channels will go differential and remove the old Vaisala CO2 channels.

Patty cleaned the solar panels.
