Radiometric sensors

Rain Gauge


Additional Tasks

Water table depths (decimal feet from top of well casing)

Note: Outside wells require regular screwdriver to open cap

inside

Off-south

Off-North

Vegetation height outside of enclosure – 20 samples (inches)

If Swapping Li-7500 Analyzer

Remove SN#

Install SN#

Indicate which ditches are full (copy and paste the red cross on the ditch number)

Other Notes:

move the diff par on the CR10x2.

calibrate methane

remove bug in the inlet

tracks still going up&down on the dirt road

drains are dry

reset methane sensor clock to match PC clock (there was an offset of 2hours !!)
