Tonzi: 2012-10-24 11:30:00 (DOY 298)
Author: Siyan Ma
Others: Erika

Summary: Just after first rain of the fall, Tree dendrometers read, Swapped 7500 at tower and Vaira, Co2 Profile down, Standard fieldwork.


When: Date: 10/24/2012 , Day: 298 , Watch Time: 11:30 am
Where: Tonzi/Vaira Ranch
Who: Siyan, Erika
Weather: showers on the way and when we just got there; rain stopped after; partially cloudy and sunshine
Phenology: Mr. Tonzi got more than 1.5 inches in his back yard; grasses were still yellow but new germination would start soon after this first good rain in the fall. Oak leaves kept falling off. Erika measured tree bands.

Summary
  1. checked and downloaded data at Tower, Floor, and Vaira
  2. Swapped Li-7500 at TZ Tower and Vaira.
  3. Gashound Li-800 didn’t work in the field and was taken back to the lab.
  4. Erika helped with measuring tree bands.
  5. Measure groundwater well: The battery was dead. I changed a new battery, but the rope ruler didn’t work very well. Measurements were made by estimation.

Vaira_Grass Site
  1. Fence and gate power: - v. (Fence was open when I got there.)
  2. Panel and Batteries: - v; - amps; - amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

Readings of CR1000:

  1. download data and swap data card of CR1000. YES!
  2. Swap IRGA Licor-7500: #418 on; #41 off.
  3. Check the fans of air temp and relative humidity sensors at Vaira. YES!
  4. Check MD-9 system connections and check CR23X with two multiplexers

Can’t talk to CR10X for soil CO2 profiles from the computer. Was able to download soil CO2 data by connecting directly to the CR10X.

  1. Check levels of Radiation sensors, clear up surfaces. YES!
  2. Check rain gage, make sure not clogged. YES!
  3. Closed gate and set up fence. YES! The lower wire of the fence was broken and missed the yellow ending. Need to be fixed next visiting.

Tonzi_Tower Site

  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

Tower Gill sonic plots screen before downloading data
  1. download data and swap data card of CR1000. YES!
  2. Swap IRGA Licor-7500: #1594 on; #976 off.
  3. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  4. Check rain gage, make sure not clogged. YES!
  5. Is the pump running‌ YES! But the readings of gashound were -99999

On average, only the two top layers of the soil got wet after the rain.

Tree band survey (with Erika’s help):
  • Total number of trees surveyed: 110
  • Total number of dead trees: 8 (total mortality: 7.2%)
  • During 2011-2012:

1) Number of dead oaks: 4
2) Mortality increment: 3.8%
3) Average of increment: 0.26 +/- 0.49 cm in perimeter (without soaking effects of rain)
  • Things may be improved: add more bands on pines‌‌
