#28 | wontfix | Correct recommended units for lat and lon | cf-conventions@… | apamment |
Description |
Beate Geyer has pointed out that the recommended units for latitude and longitude coordinate variables in sections 4.1 and 4.2 of the conventions document are inconsistent with the canonical units published in the standard name table. Sections 4.1 and 4.2 of the conventions recommend degrees_north and degrees_east for lat and lon, respectively. The standard name table uses the singular form for the canonical units, i.e. degree_north and degree_east. The two sources of documentation should be made consistent. Beate has indicated a preference for the singular form of the unit, therefore it is proposed that the conventions document should be modified to agree with the standard name table. This requires modification to the sentences in sections 4.1 and 4.2 beginning with "The recommended unit ...". Alison |

3. Requirement
4. Initial Statement of Technical Proposal
parameters to the CF standard names list it was decided to reduce this proposal to 6 new standard names thereby reducing the proliferation of new names. This reduction was achieved by introducing a 'common concept' name called 'sea_surface_wave_height' qualified by one of 4 cell methods i.e. mean maximum root_mean_square mean_of_upper_decile which will describe 4 of the statistical wave height variables: sea_surface_mean_wave_height sea_surface_maximum_wave_height sea_surface_root_mean_square_wave_height sea_surface_wave_mean_of_highest_one_tenth_waves respectively. 'mean' and 'maximum' are existing cell methods. 'root_mean_square' and 'mean_of_upper_decile' are the 2 new cell methods proposed. The other 5 new standard names proposed were: sea_surface_wave_mean_crest_period sea_surface_wave_significant_wave_period sea_surface_wave_period_at_second_largest_peak_of_variance_spectral_density sea_surface_wave_variance_spectral_density_zeroth_frequency_moment sea_surface_wave_root_mean_square_amplitude_from_variance_spectral_density 5. Benefits
other data parameters wherever statistical methods of 'root_mean_square' or 'mean_of_upper_decile' were applied. 6. Status Quo

#11 | duplicate | A standard for CF variable names ("short names") should be added. | cf-conventions@… | balaji |
Description |

3. Requirement
This name is not currently included in the standard, though some de facto standards exist. In the absence of a standard, users cannot write scripts or methods that are general enough to apply across datasets from many sources. For instance, a typical user request from GFDL is to make our internal variables names match what PCMDI (via the CMOR program) required for IPCC AR4: this would enable users who have developed new scientific analyses on their own data to apply them instantly to any model in the IPCC archive. The CF standard_name attribute does not satisfy this need. Shortcomings include:
4. Initial Statement of Technical ProposalWe propose a list of "CF short names".
5. BenefitsBenefits and use cases are coverd in some slides prepared for GO-ESSP are attached here, and also available from Balaji's home page. 6. Status Quo
