I have a grib2 dataset (gfs winds) that spans 0-360 degrees longitude, in 0.5 degree increments.<br>I need to convert this dataset into the range from -180 to 180, so I need the grid to start at 180 degrees longitude instead of at 0 degrees longitude. (fyi, the 0-360 range simply doesnt work for a custom application that Im running).<br><br>how can I perform this conversion, and store back into grib2 format?<br>can this be achieved by simply using wgrib2, or would I need to convert the data in grads, and then export&convert back to grib2?<br><br>please help,<br>thanks,<br>p.r.<br> <br /><hr />The New Busy is not the too busy.
