However, I have observed that all Fine Offset devices have very high UV values compared to nearby Davis stations. For example, my station and others in my area (Fine offset clones too) gave UV values of 6-7 in February. Davis stations in my area on those same dates never exceeded a UV value of 3.
My station (February):
Nearby Davis station (February)
In March the same. My station values 9-10 many days, Davis station maximum values of 5
I don't understand what this difference is, maybe it will be the sensor, but it is not something that bothers me
