I am writing this email to report an issue associated with the mask when using ESMF regrid in NCL (version 6.2.1).<br>
When generating the source grid file, I would like to mask the grids based on if source data is missing on specific grid cell. Hence, based on the example on NCL website, I<br>
used Opt@GridMask = where (.not. ismissing (source data),1,0). However, in the generated source grid file, field of grid_imask has a constant value of 1 for all grids, which means the Opt@GridMask was not working properly.<br>
I then switched to use Opt@Mask2D, and it worked.<br>
