Strange spikes in the relative humidity were measured on Sunday morning, before sunrise. NearSys Station is far enough away from the yard that I don't think the sprinklers were responsible for this. Otherwise, after sunrise the temperature and relative humidity behaved as expected.
There was odd spike late on the 5th when the concentration of particulate matter increased ten times. The event lasted approximately 12 hours. It can also be seen that NearSys Station was offline during the 29th.
