<div class="gmail_default" style="font-size:small">One thing I would suggest is plotting the observational lat/lon values as markers on your second plot to see if they are also misaligned with the coastlines. You should be able to use gsn_add_polymarker to plot the markers.</div>

<div>Hi,</div>
<div><br></div>
<div>I’ve binned (bin_sum) some MHS data to a model grid using rational lats and lons values (see linked <a href="https://www.dropbox.com/s/fi6s577iio47u4w/mhs_t511_si_contour.pdf?dl=0" target="_blank">fig</a>).</div>
<div>The upper panel in the figure is the model data but the bottom figure is from the observations. As you can see the</div>
<div>coastlines are slightly off and I cannot figure out why. Does anyone have any idea why this is happening to the bin_sum figure?</div>
<div>I’ve used the same set of lats and lons consistently throughout the process.</div>
<div><br></div>
<div>Any hint/help is appreciated.</div>
