<div dir="ltr">Hello:
<div><br>
</div>
<div>I am using obj_anal_ic to interpolate data (lat/lon/value) to a coarser grid.</div>
<div><br>
</div>
<div>I am wondering if the interpolation is conservative (the grid is a mercator grid).</div>
<div><br>
</div>
<div>If not, is there a recommendation on which interpolation scheme to use?</div>
<div><br>
</div>
<div>Thank you.</div>
