The Feature Fidelity task team was formed to address issues of uncertainty of satellite-derived SST fields in relation to the study of oceanographic features at mesoscale and smaller, i.e <O(100 km). Features such as currents, fronts, eddies, and gradients are defined by differences in SST over the spatial scale of interest. Critical to the study of these features is the uncertainty in the SST differences rather than the uncertainty in the absolute SST.
Objectives
Address issues of uncertainty of satellite-derived SST fields in relation to the study of oceanographic features at mesoscale and smaller, i.e <O(100 km).
Activities
Task 1: Classification of types of problems contributing to uncertainties at different spatial scales
Task 2: Identification of effects giving rise to these problems
Task 3: Outline approaches to quantifying the uncertainties of interest
Two approaches are investigated:
- Metrological approach: propagation of errors through the processing steps
- Determine uncertainty from the variance of the SST fields
