Hi:

Pinging back this thread again; I think my follow-up question was lost in
the shuffle. I'm curious if there is a way to generate the standard
deviations of observed and forecast anomaly fields when a climatology is
provided? Any insight is appreciated.

Best,
-Marcel

Hi Marcel.

Thank you for the follow up and my apologies for the lack of response.
My
guess is that Barb did not see the message you sent on the 23rd.  I
just
sent her an email about it and your message from today and am copying
her
on this message.  I do not know what her schedule is, so please allow
a few
business days for a response.  Thank you for your patience and
understanding.

Julie
