Retrieval and global assessment of terrestrial chlorophyll fluorescence from GOSAT space measurements

► We present a method for the retrieval of chlorophyll fluorescence from GOSAT-FTS data. ► The potential of GOSAT-FTS data for global fluorescence retrievals is demonstrated. ► Results are highly consistent with other state-of-the-art retrieval methods. ► A biome-dependent linear relationship between fluorescence and GPP observed. ► Strong directional effects are apparent in the fluorescence emission.
