Dear CF community, to more specifically describe sea-ice output from climate-model simulations for the CMIP6 Sea-Ice MIP (SIMIP), we would like to propose the following additional new CF standard names (as part of the SIMIP CMIP6 data request). 1. magnitude_of_sea_ice_normal_stress: Average normal stress in sea ice (first stress invariant), units 'N m-1’. This is a horizontal stress, which is perpendicular/normal to each of the vertices making up the a grid cell in the horizontal plane. The average represent the spatial average stress. Cell_method attribute "area: average” 2. magnitude_of_sea_ice_shear_stress: Maximum shear stress in sea ice (second stress invariant), units 'N m-1’. This is a horizontal shear, the areal maximum shear of the normal and shear stress stress acting on the vertices of a grid. Cell_method attribute "area: maximum”. 3. magnitude_of_sea_ice_velocity_shear: Maximum shear of sea-ice velocity field (second shear strain invariant)(new variable with units '1/s’). This is the areal maximum shear strain rate in the horizontal plane of the sea ice. Cell_method attribute "area: maximum” Thank you very much for your feedback, guidance and input.
With best wishes, for the SIMIP Steering Committee, Alexandra Jahn Alexandra Jahn Assistant Professor, Department of Atmospheric and Oceanic Sciences INSTAAR Fellow University of Colorado Boulder Campus Box 450 Boulder, CO 80309-0450 USA [email protected]<mailto:[email protected]> Phone: 303-735-3352 http://instaar.colorado.edu/people/alexandra-jahn/
