2012-09-27 I arrived about 9:15am PDT with Cove, Sara and Laurie. It was clear and sunny, warming quickly with a dying breeze from the west. The water level in the ditches and in the fields under the bridge seemed high. The middle ditch in the field was completely full. The pepper weed seems to be still gaining green through it looked a little trampled by the cows. The cows have been working over the power pole and boxes. I need to repair the fence around it. The LGR read: 8:19PST, 23.96C, 140.9Torr, 13.81usec, 10Hz, 2.05ppm Cove adjusted the bypass valve to bring the pressure up to 145.5Torr. The met and soil CO2 looked okay, as did the flux data: CO2 = 17.4 mmol/m3, H2O = 660 mmol/m3, P = 101.3, T = 19.56, Diag = 248 We collected all the data and Sara measured soil flux. We installed an ATI sonic borrowed from the Goldstein lab. The ATI is mounted directly south of the Gill sonic at the same height. The ATI sonic is connected to the CR1000 by its RS232 port. I added an adapter so that the computer now talks to the CR1000 on the CSI/O port. The ATI data (U, V, W, and SOS) is being collected at 10Hz in a third, separate table within the data logger. This should synchronize the data, but not change the format of the existing tables. The CR1000 program was changes after swapping cards. The ATI is using 19200, 7, 1, even for coms. I cleaned the radiometers and tipping bucket – they were all slightly dirty. |
