Summary: Swapped 7500, grass beginning to grow, soil samples, spectral measurements

When: Date: Nov, 2,2004 , Day: 307 , Watch Time: 10:30am .
Where: Vaira Ranch
Who: Siyan
Weather: clear, sunny
Phenology: green up, grass about 2 cm high

Summary

  1. Swap Li-7500 in Vaira (remove sn 0041, install sn 0418)
  2. I did the spectrometer measurement.
  3. Soil moisture increased ~20%.
  4. leave and grass samples: Vaira grass, Tonzi understory grass, and Tonzi tree
  5. Soil samples: 2 in Vaira.
