Hi!

So I had a question....Why am I reading on netc map CPM is around 26 for Sacramento CA.

When I go on the EPA website and ask for information on Sac I see graphs showing me over 1000

Is there a disconnect, am I missing something....

Can anyone shed light?

The Netc maps show private Beta sites (starting with a 1:) and EPA Beta sites (4:), and for subscribers also the EPA Gamma sites (5: series, one of the 8 bands). The sensors used for measuring Beta and Gamma are different and higher readings for Gamma are expected. See https://www.netc.com/bb/viewtopic.php?f=6&t=278.
