Figure 12: Polar view of the column-integrated water abundance and the partitioning index. Observations northward of 45° are averaged on a 1°x7° latitude-longitude grid, in intervals of 30° Ls. The top two rows show the full column abundance of the synergy retrieval (first row) and MCD prior (second row). The bottom two rows show the retrieved partitioning index (third row) and the MCD prior partitioning index (bottom row). A higher partitioning index indicates more water kept close to the surface.
