<div dir="ltr"><div><div><div><div>Hi Basit,<br></div>I would suggest setting cnFillMode = "RasterFill" to see exactly where data is present. The default setting for cnFillMode ("AreaFill") will not necessarily show a grid box with data if there is missing data present anywhere around the grid box. This is the case here.<br><br></div>If you are set on interpolating, you can try to use the poisson_grid_fill function:<br><a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/poisson_grid_fill.shtml">http://www.ncl.ucar.edu/Document/Functions/Built-in/poisson_grid_fill.shtml</a><br><br></div>Note that this function will fill in _all_ areas with data. It would then be up to you to mask the land out after using poisson_grid_fill.<br><br></div>Hope that helps.. If you have any further questions please respond to ncl-talk.<br>Adam<br><div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Feb 16, 2015 at 3:36 AM, BasitAli Khan <span dir="ltr"><<a href="mailto:BasitAli.Khan@kaust.edu.sa" target="_blank">BasitAli.Khan@kaust.edu.sa</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div style="color:rgb(0,0,0);font-family:Calibri,sans-serif">I want to plot SST from ECMWF-Era-Interim 0.75 x 0.75 degree data. The SST field in this dataset is land masked that is all the land points are 'missing values' . However, due to coarse resolution,
there are white spaces along the shorelines (please see the attached figure). I want to interpolate SST up to shorelines so that no white spaces are shown in the plot. I wonder how can i do this.</div>
<div style="color:rgb(0,0,0);font-family:Calibri,sans-serif">Any help would be greatly appreciated.</div>
