satpy.enhancements.ahi module

AHI specific enhancements.

satpy.enhancements.ahi._jma_true_color_reproduction(img_data, platform=None)[source]

Convert from AHI RGB space to sRGB space.

The conversion matrices for this are supplied per-platform. The matrices are computed using the method described in the paper: ‘True Color Imagery Rendering for Himawari-8 with a Color Reproduction Approach Based on the CIE XYZ Color System’ (DOI:10.2151/jmsj.2018-049).
