Summary: Ted changing cr10x program.
| Feb 23 Ted changing soil Cr10x program.removing line of junk.. Will reset the soil data loggers and remove Theta probe and soil heat flux from gmet WHEN: Friday, 2/23/2001 WHERE: Sacramento, CA Dept. of Water Resources; Tonzi Ranch, Ione. WHO: Nancy Kiang (other people: Ted, Liu Kang fixing Vaira Ranch soil temperature multiplexer and continuing to set up Tonzi Ranch understory system. Kevin Tu, Francesca measuring soil respiration at Vaira Ranch. WEATHER: Clear, patchy big clouds after rain, ~50° F. Water is ponding on the ground, but ground is firm. Sacramento. Arrived 9:00 am at CA Dept. of Water Resources, Office of Photogrammetry and Mapping. They have 1981 B&W aerial photos of the Irish Hill Road area, original negatives (1"=2000'), stereo images. Selected two photos that cover the Tonzi Ranch. Other photos also cover the Vaira Ranch. They provided names of aerial photo labs that will print the photos, so we must obtain a cost estimate. These aerial photo labs may also have their own stock of more recent photos. Tonzi Ranch. Arrived ~10:45 am. Downloaded sapflow data. Set up coax cables for MD9 between Set Q sapflow sensors and the understory eddy flux system. Could not get the computer to see the MD9, although we tried several different COM ports. Ted thinks that we can string up the various systems via MD9's in the order: Set P sapflow sensors - Set Q sapflow sensors - understory eddy flux - overstory eddy flux so that they are all along one line, and that it's unnecessary to stretch coax cable twice to the far sapflow setup. So, we could return half of that PVC pipe. Liu Kang collected grass LAI from the Tonzi Ranch, within the northwest footprint area, 3 samples under trees, 3 samples from the open. |
