Day 7

Standard Time in: 2:20 Out:

Who: Ben & DB

Weather: clear and windy, very wet

Phenology: weed almost dead, few patches of green grass

Tasks

  1. check and download data at Sherman Island
  2. download data from laser and calibrate

Check list

  1. Fence and gate power: Ok
  2. Datalogger Solar Panel and Batteries:
  3. Reading from Gillsonic (H2O and CO2 should be in the range of 0 – 5 v.)

NO POWER

  1. If Swapping Li-7500 Analyzer. (Remove SN# ; install SN# )
  2. Check the fans of air temp. and relative humidity sensors
  3. Check MD-9 system connections
  4. Check CR23X with two multiplexers and sensor values
  5. Check levels of Radiation sensors, clear up surfaces.

Closed gate and set up fence.
