This sensor was disconnected from the data logger two weeks before. This sensor was moved to GT to replace the incoming PAR there that was having negative values at night.
5231 2021-03-30 Lab none Installed East End none Installed in EE wetland to measure undercanopy PAR. This sensor is S of the tower mounted on a grounding rod. The sensor is sitting in a heterogeneous patch of dried reeds about 30cm above the water level
