Summary: Datalogger program for the Kipp & Zonen range changed. Check and download data at Sherman Island. Took TDR soil moisture readings. Changed inlet methane tube.

When: Date: 10 May, Day: 130, Watch Time: 12-15.

Where: Sherman Island Methane Study

Who: Matteo

Weather Clear Sky , pretty windy

Phenology tall grass in bloom

Tasks

check and download data at Sherman Island
Take TDR soil moisture readings
changing inlet methane tube

Sherman Island Pasture Site

Fence and gate power: OK.
Datalogger Solar Panel and Batteries:12.8v;
Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 â€“ 5 v.)

Methane Sensor
1. Cell Pressure (near 159 Torr?): 155.4
2. Cell Temperature: 26.28
3. Double Check

i. Sample rate: 10Hz?: yes

ii. Methane ppm Hi flow:

iii. Methane ppm, low flow (remember to put back in high flow:

iv. Pump status??:____

v. Filter Status:______

vi. Check Water in tube:

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

Closed gate and set up fence.

Other Notes:

The Temp/RH fan was working properly.

I changed the datalogger program for the Kipp & Zonen range measurements from 2500 mV to 25mV.

No water in the tube that comes out of the pump box
