I arrived about 1pm with Patty. It was mostly sunny with some high clouds and mild. There was a nice breeze from the west. The rice has headed.

Patty tried to complete the LAI measurements from last week, but only got one reading before the LAI meter stopped working again. She did canopy height.

The 7700 read: 1.94ppm CH4, 60.9 RSSI – I did not clean things.
The 7500 read: 381ppm CO2, 740mmol/m3 H2O, 94.0 SS, 101.8kPa, 25.4C

I cleaned the tipping bucket.

The fan for the HMP45 had died. I replaced it.

I checked the camera power line but it looked okay and had the correct voltage.
