Got a similar reply the other day.
"Matt,
If no one has gotten back to you, let me try to help.
I'm familiar with one solar radiation issue with CWOP.
MADIS transitioned to Operations at NWS. The version transitioned
did not have the solar variable for CWOP in it. We have a deficiency upgrade in
the works to fix this problem. I don't know when the upgrade will be.
if your issue is a different one, please explain it to me.
