Vandals!

In a controlled experiment, as many variables as possible are accounted for, a hypothesis is conceived.  The experiment is carefully planned, laid out, and implemented.

Weather stations and pendant sensors used at our field sites being prepped for launch.


Take all of that planning and equipment to the field however...

A temperature/RH sensor hides in this radiation shield that was knocked over and wire severed.

 A sensor set-up measuring temperature/RH and soil moisture knocked over and pulled up.

 A weather station pulled completely out of the ground.

A repaired radiation shield stayed put, but the pendant sensor was bitten and cast aside.


A temperature/RH sensor that was pulled apart and chewed.

This damage had occurred over the course of several months and we had our suspicions as to who was responsible.
