Testing and bug fixing is taking frustratingly longer than planned, I am
discovering why no one has done this before I think!! But I am still on
track to submit a 20yr control run before I depart for the christmas
week. This is important to act as the reference against the UKCIP
control run to check the impact on equilibrium climate of the new land-
surface scheme. This will mean that I am then ready to submit the first
transient run in Jan, so late jan at earliest for results I think.

No. I have estimates of heat flux for London boroughs estimated from the
London energy and CO2 inventory publication from the Mayor of London. As
we discussed it would probably be beneficial to make sure what I use is
consistent with LUCID. I will contact Mike and cc to you.
> Have you finalised the scenario for your run 2?
No. I was planning to submit a proposal for discussion ahead of the next
SCORCHIO meeting on Jan 17th. I have also suggested to Clare Goodess
that I visit UEA in the new year for further discussion, but we have not
fixed a date yet.

My understanding was that it was daily resolution fields, and hourly
might be desirable but not essential. Hourly would provide significant
additional overheads for data storage and extraction. Would the loss of
hourly result in severe limitations of Tyndall work?
