Students in the engineering program and working to consider different ways to update one of the greenroofs on campus. Like many Portland ecoroofs, after nearly 10 years, this one is much different now compared to the original design. Students are weighing different maintenance options to ensure continued ecosystem services. Here we are getting new batteries into the weather station. (Photo credits: Laura Gleim)

Preliminary analysis suggests that the greenroof filter is still better at removing ozone from the air, but we will need to look into this further....
