The weather.com UV index only goes up to 10, so I think it is on a different scale. On the Acurite Atlas (as is on my Ambient) the range is 0 to 16. My point is that perhaps an index of 8 on weather.com is not equivalent to an 8 on our stations.
But maybe I'm wrong and weather.com only reports up to 10 and the scale is the same.
I'm allearseyes if someone has an nice little lesson on this topic.
Good point, didn't think about the UV scale would/could be different. Something to look into. I also don't like the website's data being 30-50 minutes behind real time. The main reason I looked at sites was because people were stating that their Atlas was under reporting UV data. Mine seem low but I didn't really know what it should be. My UV data seems right and matches my neighbors.
