Summary: Reconstructed boardwalk, LAI2200 measurements, normal data collection

Arrived 12:10. Sunny, hot, very light breeze. Field is flooded and rice is growing nicely. Lots of tall weeds growing amongst the rice, and algae on top of the standing water. Water is lower than last time.

Methane wash water reservoir full. Collected USB GHG data, collected met data from23X, did not collect camera data because Joe collected it last Friday.

Took veg height, clip plot and LAI 2200 measurements.
Veg height: 73,64,62,66,74,72,72,74,75,67,71,79,73,70,72,78,74,82,66,79
Weed height: 135,115,131,107,110.

Kyle reconstructed the boardwalk so that it won’t be in the water when the water level rises again.
