Greenroof East Temperature Anomaly – by Logan Gerber-Chavez

Last week after installing the control probe we took a look at the temperature data. Three of the probes temperature came up above the others by 4-5 degrees Celsius. We wanted to check the rest of the data over to see if the strange anomaly in the top right corner was due to building interference or shadows or probe malfunctions. We waited a week to collect the data including the control probe.

From the graph we see that all of the probes still collapse within a degree in the mornings for the minimum so the difference is probably not due to probe malfunctions or building interference unless it is just a daily problem but it could be due to shadows. We would like to install a surveillance camera to monitor the shadows throughout the day.
