Have you ever wondered what all those pretty colors on the various radar
maps you see mean and compare to the different sources?
See the link below.

Dave writes a column in IFR that explains how things work.

Yep, good article. The only item I would have appreciated seeing on the
chart
would have been the actual precip return strength in DBZ and perhaps that
new
ATC precip classification (light, moderate, heavy, etc). But this chart is
an
excellent starting point.


Is there an article on that link?

No, no article.
There is an interesting podcast on AvWeb that led me to the website.
The podcast is basically a teaser to subscribe to IFR.
