Summary: Regular data download and site maintenance + replaced boardwalks

Arman and I arrived at ~08:30 PST. It was sunny and warm with quite a bit of weeds by the tower. Charlotte from Whendee's lab arrived as we were doing the tower maintenance.

At the tower, I dowloaded MET, GHG, purple air and camera data. The camera card had full set of images, I moved images and re-inserted this same card back. As I collected the MET data, the default settings were changed with downloaded data starting from 2025-01-29. But both 30min and 5min had data until 2025-03-25
The LI-7700 reservoir was 2/3 full, and we refilled it.

Arman and I repalced the old boardwalks with new ones.

The water level was 30.5cm below the ground.
(Top of well pipe to water level = 151.5cm, (Previous visit measured) top of well pipe to ground = 121cm)

7500 read: 626ppm CO2, 678mmol/m3 H2O, 20.3 C, 101.5kPa, 98.6SS --99 after cleaning

We left the field at around 09:35 PST.
