This is a global data set on 0.5 degreee latitude and 0.5 degree longitude monthly resolution of oceanic sun-induced chlorophyll a fluorescence (SIF) at its red peak from January 2003 to December 2011. It was retrieved from top of atmosphere radiance measurements from the hyperspectral instruments SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY (SCIAMACHY) at its red peak (~685 nm) based on the Differential Optical Absorption Spectroscopy (DOAS) technique. This technique was used to exploit narrow spectral structures resulting from the filling-in of the Fraunhofer Fe I line, which originates from fluorescence. The reference spectra for chlorophyll fluorescence were calculated by the coupled ocean-atmosphere radiative transfer model SCIATRAN. We compared our results on marine chlorophyll fluorescence line height (FLH) observations with the MODIS Terra normalized Fluorescence Line Height (nFLH) product for the average of years 2003 to 2011 showing good agreement between the two data sets. All the details on the retrieval method and its evaluation can be found in Wolanin et al. (2015).
