Hans,
This email bounced from Bruno's site. His email is
Rudolf Bruno <Bruno.RudolfatXYZxyz.de>. Is Bruno on AGG?
Probably doesn't matter as you'll send out the AGG
recommendations to all of AOPC soon. Maybe you can
highlight the extra things people said they would (e.g
Carolina, she may be the only one) follow up.
Cheers
Phil
Hans,
Attached is David's file with a few additional changes.
1. OK to have unique in the section on Calculation of mean monthly stats.
2. I've removed the tongue-in-cheek sentence. I still expect Tom to send details
to Mike at the end of September though.
3. I would go with your suggestion of adding Willis Is. to the GUAN, so approach
Australia. Keep Townsville in the network though.
4. Finally wrt certificates, the AGG report should include the values for X and Y
finally used by Tom to decide which GSN and GUAN sites get which stars on their
certificates.
Cheers
Phil

Thanks. I have made a few changes which don't relate to your comments
below.
I think the 2nd paragraph under GUAN on page 5 aims to check that
stations haven't become silent. If there are, say, 8 stations missing in
each month, then if these stations differ from month to month then the
stations are not silent, whereas if the same stations are always
missing, then they are silent.
I'm easy about Willis Island.
Regards
David
