Replace NaN by number.

Your Band Math expression worked perfectly for what I needed.
About using the ArcGIS, I'm really more used to work with geoTIFF files on that, but considering those advantages on NetCDF4-CF I'll check it out.

Thank you for your help sir. Have a very nice day!

Replace NaN by number.

The math band generates the new raster and I'm checking it on the own Seadas. I'm not exporting or saving the raster. I acctually do want to export it as Geottif to work on arcgis; but since the NaN isn't being replaced by a number there's no reason for me to export the raster image....

Replace NaN by number.

Any ideia why does this happens? I'm really stuck at this...
