Dear Dan,

Thanks for your standard name proposal - you have done all that is necessary for it to be 'picked up'. I am the person responsible for updating the standard name table (the latest version can be viewed on the CF website at http://cfconventions.org/Data/cf-standard-names/27/build/cf-standard-name-table.html). I also maintain a list of proposals that are in the pipeline, so to speak, which is linked from the website 'Discussions' page (http://cfconventions.org/discussion.html) or can be viewed directly at
 http://cfeditor.ceda.ac.uk/proposals/1?status=active&namefilter=&proposerfilter=&descfilter=&filter+and+display=filter. Your proposal has been added to this list. (N.B. I am also in the process of adding other recent proposals to bring the list up to date as it hasn't been done for a while).

I agree with Jonathan that your proposal for number_of_days_with_surface_temperature_below_threshold is fine and since it is so similar to an existing name I think that unless anyone raises any objections within the next week it can be accepted for publication in the standard name table.

Best wishes,
Alison
