Re: [CF-metadata] add_offset for time dimension

2010-09-17 Thread Jonathan Gregory
Dear John and Benno No, CF doesn't specifically exclude add_offset for coordinate variables, but it only talks about it regarding packing data variables, and in Table A it is listed only as an attribute of data variables, not coordinate variables. I think that's because coordinate variables don't

[CF-metadata] CMIP5 carbon cycle standard names

2010-09-17 Thread Jonathan Gregory
Sorry, one other one which Pierre didn't remark on. This name is rather obscure, even bizarre :-) miscellaneous_living_compartments_carbon_content I wonder if we could convey this meaning any more plainly? What about carbon_content_of_miscellaneous_living_matter ? Jonathan

[CF-metadata] CMIP5 cryosphere standard names

2010-09-17 Thread Jonathan Gregory
Dear Alison and Siobhan Sorry for late comments on the cryosphere names. I commented this week on shear. I was wrong to suggest that sea ice shear is like wind speed shear, because the latter is the vertical derivative of a horizontal speed, whereas sea ice shear is (I think) a horizontal

[CF-metadata] CMIP5 cryosphere standard names

2010-09-17 Thread Jonathan Gregory
Dear Alison surface_downward_heat_flux_in_snow; Wm-2 I think there is a need to have distinct surface heat fluxes in the media on either side of the surface because there might be a phase change going on actually at the interface, so there would then be a vertical divergence in heat flux at the

Re: [CF-metadata] Seeking new CF standard names (9) for sea surface wave parameters

2010-09-17 Thread Lowry, Roy K
Hello Jonathan, The term 'statistics' has a slightly different meaning for wave data. Essentially, what wave instrumentation does is record vertical displacement of the sea surface at very high frequency for a period of say ten minutes. Spectral analysis techniques are then used to derive
