I arrived about 11:15 with Daphne. It was clear and sunny but with a little haze and not much wind. They were mowing the field last time we were here. Now it has been baled and the bales have been removed from the western half of the field. There was water in the ditch along the south edge of the field.

We swapped the 7500:
sn 75H-2176 came off: 343.8ppm CO2, 858.3mmol/m3 H2O, 27.4C, 101.32kPa, 75.9SS
sn 1594 went up: 409.7ppm CO2, 456.9mmol/m3 H2O, 27.75C, 101.5kPa, 100.1SS
The config file and pressure coefficients were updated. There were lots of spider webs on the one that came down and the sonic.

We had trouble with the USB stick on this tower. The stick did not seem to eject properly then the new stick did not mount properly. Resetting the box allowed the new stick to mount and start recording data. Initially we could not get the files to move off the USB stick that was removed. Repairing the drive seemed to work but somehow made the stick read only. We were able to copy the existing files off the disk, but could not remove or reformat the drive for use elsewhere.
