QA4ECV FAPAR

QA4ECV FAPAR provides quality-assured, traceable Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) datasets to monitor vegetation health and assess drought impacts.

Key Features:

• Quality Assurance Framework: Employs a comprehensive quality assurance framework that produces understandable and traceable quality information for FAPAR datasets.
• Drought Monitoring Capability: Monitors drought impacts on vegetation greenness and health, with applications in regions such as Australia.
• Data Integration and Comparison: Facilitates spatial and temporal comparisons with FAPAR products from MODIS and SPOT/PROBA-V generated by the Copernicus Global Land Service (CGLS).
• Correlation with Drought Indices: Correlates FAPAR data with the Standardized Precipitation Evapotranspiration Index (SPEI) and soil moisture from the European Space Agency Climate Change Initiative (ESA CCI).
• Reliable Uncertainty Information: Provides traceable and reliable uncertainty metrics associated with FAPAR datasets.

Scientific Applications:

• Climate change impacts on vegetation: Supports research on climate change effects on vegetation using consistent, quality-assured FAPAR data.
• Agricultural drought assessment: Enables assessment and mitigation studies of drought impacts on agricultural productivity and ecosystem health.
• Environmental monitoring and decision support: Supports integration and comparison of multiple FAPAR datasets for environmental monitoring and decision-making.

Methodology:

Applies rigorous quality assurance protocols to satellite-based FAPAR observations, uses standardized retrieval methodologies to address differences among existing FAPAR products, and performs spatial and temporal comparisons and correlations with MODIS, SPOT/PROBA-V (CGLS), SPEI and ESA CCI soil moisture across multi-decadal records.
