Combining in-situ and satellite for estimation of carbon flux (D7.6)


The integration of in-situ measurements with satellite data offers a holistic and more comprehensive approach to estimating carbon fluxes, which are pivotal in understanding the carbon cycle and its role in global climate dynamics.

Impact During the Project

Increased Data Resolution and Coverage:
Traditional State: Historically, either in-situ measurements or satellite data were used independently to estimate carbon flux, which might offer detailed localized data or broad but less detailed global coverage, respectively.
Advancement: By combining both data sources, there’s an enhancement in both spatial and temporal resolution. This union ensures that there’s broad coverage from satellite data complemented by the precision of in-situ measurements.

Accuracy and Validation:
Traditional State: Relying on a single data source might have led to potential gaps or inaccuracies in estimations, without an effective way to cross-verify the results.
Advancement: With the merger of in-situ and satellite data, there’s a cross-validation mechanism in place. Discrepancies between the two data sources can be identified and rectified, leading to more accurate carbon flux estimations.

Dynamic Monitoring Capabilities:
Traditional State: In-situ measurements, being localized, might miss out on capturing large-scale dynamic changes, while satellite data might not capture finer details.
Advancement: Combining the two offers the capability to capture both micro-level changes (from in-situ data) and macro-level dynamics (from satellite data), ensuring a fuller picture of carbon flux variations.

Impact Post Project

Enhanced Understanding of the Carbon Cycle:
Traditional State: With potential gaps in knowledge due to data limitations, the complete understanding of the carbon cycle might have been fragmented or partially obscured.
Advancement: A more comprehensive data set ensures a deeper and more nuanced understanding of the carbon cycle, which is fundamental for climate science.

Improved Climate Modelling:
Traditional State: Models based on either solely in-situ or satellite data might not have captured the full complexity of carbon flux dynamics.
Advancement: With improved carbon cycle information, climate models can be refined. This leads to better predictions, which are pivotal for policymaking and climate change mitigation strategies.

Informed Decision Making:
Traditional State: Limited data might have led to policies or strategies based on partial information.
Advancement: The enhanced information about the carbon cycle can guide policymakers, researchers, and industries in making informed decisions regarding carbon management, sequestration strategies, and environmental conservation efforts.

Advancement over and above State of the Art

The effort to amalgamate in-situ measurements with satellite data for estimating carbon flux represents a significant stride towards a holistic understanding of carbon dynamics in the environment. This synergy of data sources not only ensures accuracy but also provides a comprehensive view of the carbon cycle, leading to better-informed decisions in climate science, policymaking, and industrial practices. In essence, it bridges the gap between micro and macro perspectives, providing a full spectrum view of carbon flux in the ecosystem.
