Graphs for local normalization. Graphs of b₀ and b₁ for the temperature maps for the PR3 dataset for the northern (top two rows) and the southern hemisphere (bottom two rows)The variance is computed for each hemisphere separately from the unmasked pixels in that hemisphere. The graphs present the normalized differences, and each panel presents the graphs for a range of degradation and smoothing scales. The mask used is the PR3 temperature common mask.
