The data on this page is collected from my personal weather station. It may not be and is not accurate at times. The Ambient Weather WS-5000 seems to be flaky under certain circumstances. The description is from my own observations.
I put this here for my own personal records. If you find it interesting or useful, that’s great! Especially in the latter half of 2025, I started noticing some flaky readings. I think the weather station is slowly dying. I am doing my best to come up with ways not to show the obvious errors.
