SIRENE is a project funded by the European Space Agency that leverages Earth observations and ground data to enhance the understanding of terrestrial ecosystems and the detection of their tipping points.

Global map of project regions of interest

SIRENE focuses on:

  • Developing improved methods to detect and predict climate-driven tipping points in terrestrial ecosystems  
  • Advancing ecosystem resilience metrics, addressing limitations such as noise, short time series, and external influences  
  • Integrating multi-sensor satellite data, ground observations, and long-term climate records for more robust analyses  
  • Applying machine learning and AI-based approaches to enhance pattern detection and prediction accuracy  
  • Quantifying and propagates uncertainties to support clearer and more reliable risk assessments  
  • Enabling region-specific resilience analyses, accounting for different ecosystem responses to stressors (e.g. drought, fire, deforestation)  
  • Supporting policy-relevant applications, including climate adaptation, ecosystem conservation, and land-use planning  
  • Promoting standardized and accessible resilience metrics to strengthen science–policy collaboration.

CLIMERS role:

  • Assessing if Earth observation datasets are fit for resilience analysis.  
  • Consolidating Vegetation Optical Depth (VOD) data at the single-sensor level, focusing on improving retrieval consistency in relevant SIRENE study areas.  
  • Advancing resilience metrics from satellite and ground-based data.
