General description

4

What data/products do you currently use ?

Satellite data is used for model calibration when it is configured over a new location.

5

When do you use this kind of dataset?

During asset appraisal for calibration of numerical model.

6

What are your actual limitations and do you have a work around?  

Large temporal and spatial smoothing in most altimetry product makes model calibration difficult.

Some models such as OGCM for example are not uniformly consistent.

7

Needs and expectations on EO data

  Direct measurement of currents is necessary.

SAR data from Sentinel-1 are expected.
