| 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), This is a regional subset of the variable. If you are producing the global equivalent of SImon.sivSouth30, you should omit this regional South30 version. If the global equivalent of this variable is not in the Data Request, you can still produce that instead of the regional variable if you prefer, and you will be able to publish it. |
