Murray, Question. What projection are you using for your data? If you are using a lat/lon projection there may be a workaround. In particular, there is a grid diagnostic formula called "lonflip" that may offer a solution. From the documentation: "Flip the longitudes in a grid from -180-180 to 0-360 (or vice-versa). Only works for cyclic rectilinear grids." Best, Unidata IDV Support > This is very good news. There is an equivalent "tool" in Saga GIS that works > well, and their code is public domain.
