            <comment> This map has been smoothed 
                using a two-dimensional moving average (boxcar) filter.  
                Its effective resolution is approximately 51 km.
                For a detailed description, see Hood et al., GRL, in review, 2022.  
                Zero values indicate no reliable data.</comment>
