Evaluate your own maps

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.

Maps format

The input netcdf files must contain:

• latitude, longitude and time dimensions.

• for sea level anomaly evaluation, a sea level anomaly variable sla.

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'}).
