TanSat Solar-Induced Chlorophyll Fluorescence, Global 0.05° Resolution

Global spatially continuous TanSat solar-induced chlorophyll fluorescence product at a wavelength of 758 nm. The dataset has a spatial resolution of 0.05° and a temporal resolution of four days, with Version 2 providing daily SIF under clear-sky and all-sky conditions. It was created by Yan Ma of the Chinese Academy of Sciences and retrieved via singular vector decomposition from original TanSat SIF data.

Use Cases

• Modeling global vegetation productivity based on solar-induced chlorophyll fluorescence.
• Monitoring crop health and agricultural yields using spatially continuous fluorescence data.
• Studying the terrestrial carbon cycle with daily clear-sky and all-sky SIF estimates.
• Calibrating and validating other satellite-derived vegetation indices.

Strengths

• Provides a spatially continuous global product at a 0.05° resolution.
• Offers daily solar-induced chlorophyll fluorescence estimates under both clear-sky and all-sky conditions.
• Data is derived from TanSat satellite observations, an authoritative source for atmospheric and environmental monitoring.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
