The variables included are the Fluorescence Quantum Efficiency at leaf level (ΦF) (740 nm) as well as all variables included in the calculation. Multiple support bands are included that give insight into the data quality of the ΦF and SIF product.</abstract><sumDscr><timePrd cycle="P1" event="start" date="2018-05-01">2018-05-01</timePrd><timePrd cycle="P1" event="end" date="2025-08-01">2025-08-01</timePrd><dataKind>Remote Sensing Data</dataKind><dataKind>Gridded Raster Data</dataKind></sumDscr></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/></dataAccs><othrStdyMat/></stdyDscr></codeBook>
