Sub-band brightness temperature difference at band 3, ΔT_b|_B3, (top panels) and at band 6, ΔT_b|_B6, (bottom panels) at the original resolution of the numerical model and at the resolutions corresponding to array configurations C1 to C7 for the respective receiver sub-band (Table B.1). The T_b maps are individually degraded to the respective resolution before the differences were calculated.
