Daily Solar-Induced Fluorescence from GOME-2 Satellite, 2007-2018

NASA EarthData and Data.gov host the L2 Daily Solar-Induced Fluorescence dataset from the GOME-2 instrument on the MetOp-A satellite. It provides daily global land estimates of chlorophyll fluorescence at a spectral resolution of ~0.5 nm between 734 and 758 nm from February 2007 to February 2018. The data, produced by ORNL_CLOUD, includes raw and bias-adjusted SIF values, quality control flags, and ancillary information.

Use Cases

• Modeling global primary productivity using daily bias-adjusted SIF values.
• Assessing vegetation stress and light-use efficiency via chlorophyll fluorescence measurements.
• Validating terrestrial carbon cycle models with over a decade of global satellite observations.
• Monitoring agricultural crop health and functional status across growing seasons.

Strengths

• Provides over 11 years of continuous daily global land coverage from 2007-02-01 to 2018-02-01.
• Includes both raw and bias-adjusted solar-induced fluorescence values for analysis flexibility.
• Spatial resolution improved from 40 km x 80 km to 40 km x 40 km after July 15, 2013.
• Features detailed spectral data with ~0.5 nm resolution in the 734-758 nm wavelength range.

Limitations

• The product is inherently noisy due to low signal levels and has undergone only a limited amount of validation.
• Sources conflict on the last update date: one lists 2026-03-13, while another lists 2018-02-01.
• Specific column names and total row/file counts are not provided in the source metadata.
