Evaluate your denoising technique

Once you have installed the data challenge and downloaded the data, you can now evaluate your maps. Although, you might want to check first that your sea level anomaly or sea surface currents maps respect a certain format. You can then scroll through the different metrics, checking the DUACS evaluation notebooks as example.

Data format

The input netcdf files must contain:

• num_lines and num_pixels dimensions.

• latitude, longitude and time variables.

• for denoising evaluation, a denoised ssh variable ssha_method_denoised.

Note that some formatting can be done using xarray within the jupyter notebooks. For instance, you can change a variable’s name simply with ds = ds.rename_var({'my_sla':'sla'}).
