Hello, We have two similar but distinct temporal averaging use cases in the CMIP6 data request and I'd be grateful to some advise about CF encoding.
(1) Grid cells have a temporally varying sea-ice fraction, and a mean is wanted over the sea-ice area. Is this a correct cell_methods formulation: "time: mean where sea_ice area: mean where sea_ice"? (2) Grid cells which sometimes have convective cloud, and a mean is wanted over the times when there is a cloud in the cell. The variable to be averaged is, in this case, the minimum over the cell of the convective cloud base. Is this the correct cell_methods: "time: mean where convective_cloud area: minimum"? In the first case the first case "mean where sea_ice" refers to the portion of grid cells have sea_ice, in the 2nd "mean where convective_cloud" would refer to whole cells ... is this OK? cheers, Martin _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
