In this experiment, steric can be represented by SSH, MASS and GIA. \[X_{steric} = X_{SSH} - X_{MASS} - x_{GIA}\] Since these processes are all Gaussian, the are additive. We have \[E(X_{steric} | Y_{alt}, Y_{GRACE}, X_{GIA} = x_{GIA}) = E(X_{SSH}| Y_{alt}) - E(X_{mass}|Y_{GRACE}, x_{GIA}^m) - x_{GIA}^{vlm}\\ V(X_{steric}| Y_{alt}, Y_{GRACE}, X_{GIA} = x_{GIA}) = V(X_{SSH}| Y_{alt}) + V(X_{mass}|Y_{GRACE}, x_{GIA}^m)\]
Now assemble the predicted mean of and uncertainty of steric at 1 degree resolution.
Plot the steric map.
We compare the steric prediction with other four steric solutions.
Now plot and compare the mean trend.
Finally, save the results in netCDF.
