| description | Mean height of sea-ice surface (i.e. snow-ice interface when snow covered) above sea level. This follows the classical definition of freeboard for in situ observations. In the satellite community, sometimes the total height of sea ice and snow above sea level is referred to as freeboard. This can easily be calculated by adding sisnthick to sifb. |

| processing_note | Note that SIMIP requests the area-weighted average for all intensive variables (i.e., variables that are not proportional to area fraction such as albedo, temperature, or heat flux). Hence, all time samples with non-zero sea-ice fraction are first multiplied by area fraction, then summed, and then divided by the sum of the area fractions. See Appendix C of Notz et al. (2016) for more detail. CHANGE SINCE CMIP6 in Cell Methods - CMIP6:area: time: mean where sea_ice (comment: mask=siconc) CMIP7:area: time: mean where sea_ice (mask=siconc), |
