Dear all I sent this message to the list a couple of weeks back, with the exception of one person it didn't get much response, he pointed out difficulty opening the file, after some investigation using Australian colleagues and talking to local IT I discovered that the correct URL is
http://www.hpsc.csiro.au/users/ofa001/Cryosphere.doc
My apologies for the confusion.
Regards
Siobhan

Subject: New Cryospheric variables
Dear all,
In November/December I circulated a list of cryospheric variables for suggested collection by the CMIP 5 models through the cryospheric community for comment. An updated version of the document with revisions following input from the community is available at
http://cherax.hpsc.csiro.au/users/ofa001/Cryosphere.doc
(you might need to paste and cut it into browser)
Jonathan Gregory pointed out the need to have new variables agreed on by this cf-metadata discussion list and I have highlighted in the document in red, new variable names which follow the CF standard name conventions. I started this process before Christmas, but due to the longer SH summer break have only just completed it. Many of the variables have been selected so that the cryospheric community can better understand thermodynamic and dynamic budgets of sea ice and additional variables have been added to categorise snow cover and permafrost regions. Some of the variables particularly in relation to the ice sheets are unlikely to be available in many models for CMIP5 timeframe but have been included for the period when the climate community Earth system models do include ice sheet/permafrost models.
The new suggested names for sea ice thermodynamic variables are
Sea_ice_albedo, Sea_ice_thickness_in_sea_ice_categories, Sea_ice_area_fraction_in_sea_ice_categories,
Sea_ice_salinity, Surface_temperature_in_sea_ice, Temperature_at_sea_ice_snow_interface, Sea_ice_age,
Sea_ice_growth_due_to_frazil_ice, Sea_ice_growth_due_to_congelation_ice, Sea_ice_growth_due_to_lateral_accretion, Sea_ice_growth_due_to_snow_ice_formation, Sea_ice_melt_amount_at_ice_surface, Sea_ice_melt_amount_at_ice_base, Sea_ice_melt_amount_at_lateral_sides, Sea_ice_total_heat_content, Downward_shortwave_flux_at_sea_ice_surface, Shortwave_flux_absorbed_in_sea_ice,
Downward_longwave_flux_at_sea_ice_surface, Upward_longwave_flux_at_sea_ice_surface, Sensible_heat_flux_at_sea_ice_surface, Latent_heat_flux_at_sea_ice_surface, Downward_sea_ice_freshwater_flux.
For sea ice dynamic variables
Eastward_sea_ice_transport, Northward_sea_ice_transport, Sea_ice_volume_transport_at_Fram_strait,
Downward_eastward_atmospheric_stress_at_sea_ice_surface, Downward_northward_atmospheric_stress_at_sea_ice_surface, Downward_northward_oceanic_stress_at_sea_ice_base, Downward_eastward_oceanic_stress_at_sea_ice_base, Eastward_internal_stress_at_sea_ice_base, Northward_internal_stress_in_sea_ice, Eastward_coriolis_stress_in_sea_ice, Northward_coriolis_stress_in_sea_ice, Eastward_sea_surface_tilt_stress_in_sea_ice, Northward_sea_surface_tilt_stress_in_sea_ice, Sea_ice_strain_rate_due_to_divergence, Sea_ice_strain_rate_due_to_shear, Sea_ice_ridging_rate.
For land surface variables
Snow_density, Snow_age, Snow_thermal_energy_content, Liquid_water_content_in_snow_layer, Permafrost_layer_thickness, Liquid_water_content_in_permafrost_layer, Active_layer_thickness, Liquid_water_content_in_active_layer, Temperature_profile_in_active_layer, Temperature_profile_in_permafrost_layer.
For Ice sheets and shelves
Land_ice_basal_stress, Land_ice_geothermal_heat_flux, Surface_ice_melt_amount, Superimposed_ice_formation_in_ice_sheet, Runoff_flux_due_to_ice_sheet_melt, Land_ice_melt_rate_at_ice_shelf_base, Marine_ice_accretion_rate_at_ice_shelf_base, Ocean_temperature_in_ice_shelf_cavity, Ocean_salinity_in_ice_shelf_cavity, Ocean_temperature_at_ice_shelf_cavity_front, Ocean_salinity_at_ice_shelf_cavity_front, Surface_orography_at_ice_sheet_surface.
Best regards
