You could (only for the mask probably), output only at full<br>coarse level steps, if don't need it more often. You could also try<br>(although here I am less sure that this will prevent interpolation) to<br>restrict the output of the mask to some of the finer levels only, at<br>full time steps of these.<br></blockquote><div><br></div><div>I'm not interested in the mask, and I don't output it.
