Hi Susan, according to Wikipedia
(https://en.wikipedia.org/wiki/Ultraviolet_index), it looks like the UVI is
the weighted UV radiation divided by 25 mW/m2 which would be, in terms of
uW/cm2 , "divide by 250", I think. This should yield a number between 0
and roughly 12. Does it?

Hello Bob,
I found the same information (in answer to my Q3) and I've used that. The
HP1000 (and clones) provide different information in various records: form
the NOWRECORD (the current observation data) it provides the UVI directly,
but the HISTORY_DATA record has the UV value but in uW/cm^2.
