Brightness temperature distributions corresponding to different receiver bands and array configurations. Left column: brightness temperature distributions at the original resolution for the respective spectral band in each of the three different regions. Top left panel: QS. Middle left panel: FS. Bottom left panel: FP. The circles mark the mean values of each distribution, whose values are also indicated at the x-axes. Right column: brightness temperature distributions of bands 3 and 6 at the resolutions of the original model and array configurations C1 to C7. The average values of each respective distribution are marked at the x-axes. The T_b scales are different in each row.
