Tonzi: 2003-07-31 09:00:00 (DOY 212)
Author: Dennis Baldocchi
Others: T Dawson, K Tu, Tasha and Anthony. Ted

Summary: Show and tell, standard systems check

Where: Tonzi/Vaira Ranch
Who: DDB, accompanied by T Dawson, K Tu, Tasha and Anthony. Ted was at site
When July 31, 2003, d212

Arrived ~9:00 hrs. Mild day, high scattered clouds. Tair 27, RH 40%. Will be a good case study for Ps and lags in Respiration.

Wind profile is installed above the canopy for canopy aerodynamics

W: 1.2; u 2.56; v –2.5; T 33.6; q: 2.87; C 1.5

Downloaded data. Signals look good. Sucking up CO2.

On CO2 profile system, tanks aok
N2 800 psi
CO2 1800 psi

10:03 at Floor

Panels 13.3 v; 14 am gen; 2.5 amp load

W: .42; u -/14; v .74; T 32.3; q: 3.12; c: 1.57

Installed md9_8.exe on the Pc208 programs for renaming U profile data. Ted will need to set scheduler. Cr10x8.dat is the normal file.

Took soil moisture data

Jianwu said it rained after 4 pm and he did a pulse study. Nice case study on respiration. No rain through tree, but rain to open systems.
