Summary: 3 TC probes were not working; datalogger reset at 14:53; cleaned radiometers; installed new 60 micron filter; swapped pump; downloaded Sherman Island data.

Sherman Island - Methane Study

Date: 20 Sept 2007

Day: 263

Standard Time in: 9:40 Out: 16:20

Who: MD & TH

Weather: overcast, drizzly in the morning, open in the afternoon, no wind

Phenology: peeper weed dry on top, renewing greenness from the bottom

Tasks

  1. check and download data at Sherman Island
  2. Swap pump
  3. new filer 60 micron
  4. cleaning radiometers

Check list

  1. Fence and gate power: OK
  2. Datalogger Solar Panel and Batteries: 12.9
  3. Reading from Gillsonic (H2O and CO2 should be in the range of 0 – 5 v.)

Water traps

  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.

Other Notes:

3 TC are not working : TC1_2cm, TC2_16cm, TC2_32cm

14:53 reset datalogger

Remember next time to:

Large heat shrink in tool belt (pens too)

Study diff band program

Need a net cable 40’

Need Ethernet card

Buy plastic box for fittings ete

Take ¼” compression fittings

Replace low flow exhaust

Order 60 micron filter element or larger SS-8F-K4-60

14” wire-tighters
