Dear Alejandro,
Apologies for the delay in replying to your question. I can confirm that these names, units and definitions are all accepted for inclusion in the standard name table (see
http://cfeditor.ceda.ac.uk/proposals/1?status=accepted&namefilter=&proposerfilter=Alejandro&descfilter=&unitfilter=&yearfilter=&commentfilter=&filter+and+display=Filter) for up to date status.
The names will be added in the next update of the table, scheduled for May 17th.
Best wishes,
Alison
