Daily Solar-Induced Fluorescence from MetOp-B GOME-2 Satellite

2013-04-01 to 2021-06-07 of daily global land observations provide Level 2 Solar-Induced Fluorescence (SIF) estimates from the GOME-2 instrument on the MetOp-B satellite. The data includes raw and bias-adjusted SIF values, quality control flags, and ancillary information at a spatial resolution of approximately 40 km x 80 km. This dataset, produced by ORNL_CLOUD, supports research into vegetation function and the global carbon cycle.

Use Cases

• Modeling global carbon cycles using daily bias-adjusted SIF estimates as a proxy for photosynthetic activity.
• Assessing vegetation stress and light-use efficiency by analyzing raw SIF signals across different biomes.
• Validating other satellite-derived vegetation indices using the ancillary quality control information provided with each observation.
• Studying seasonal and interannual variability in plant productivity using the eight-year time series of daily global land data.

Strengths

• Provides a continuous eight-year time series (2013-2021) of daily global land observations.
• Includes both raw and bias-adjusted SIF values alongside quality control flags for data filtering.
• Covers a wide spectral range (734-758 nm) at a high spectral resolution of ~0.5 nm for SIF retrieval.

Limitations

• The product is noted as inherently noisy due to low signal levels and has undergone only a limited amount of validation.
• Conflicting 'last updated' dates exist between sources (2026-03-13 vs. 2021-06-07), creating uncertainty about recent maintenance.
• Specific row counts, file sizes, and detailed column names are not provided across any platform.
