Summary: Instruments dusty. Measured direction from tower to big tree: 301 N (true).

Wetland Construction
2013-06-18

I arrived around 13:30 PDT. It was warm (22 C), sunny, and very windy. Everything was dusty, and the construction looks to be getting nearer. I cleaned all the flux and radiation instruments.

I also took direction measurements from the tower to the large tree to the west of the tower to see if there is any problem from the data in that direction. The tree is 301 N (true) from the tower.

7500 readings:
CO2 = 12.3 mmol m-3 (16.4 after cleaning)
H2O = 1300 mmol m-3 (410 after cleaning)
Diag: 251 (249 after cleaning)
t = 25.5 C
p = 101.2 kPa
sos = 345 m s-1
