Hi Mary,
<div><br>
</div>
<div>I understood what you meant. Apologies for the ambiguity.</div>
<div>My script is a long one and it is not yet a running smoothly and bug-free.</div>
<div>I’ve sent an attachment along with a subset of the data: </div>
<div><br>
</div>
<div>https://www.dropbox.com/sh/gac3w26dzdtpd8y/AACrzZSVc3Fj5Dinh137E9Ywa?dl=0</div>
<div><br>
</div>
<div>I’m rethinking how to best bin and average the data. There is still problem, which I sent in as a issue today and that is how to I conform a vector X of length, say 10, with another vector B of length 20, for example ( see line 154).</div>
<div><br>
</div>
<div>As you can see from the script I use the model's lat lon to for the grid on which the MHS data is binned. In this case I’m using a square grid where the lat and lon spacing are equal. The lats and lons are from the model are not changed, which is why I
suspect the binning. </div>
<div><br>
</div>
<div>Of course this is not the plot script as there is another averaging script in between. This is why I was hesitant to send any data as I’m trying to eliminate much of the secondary averaging and ensure this initial binning of the data is done correctly.</div>
<div><br>
</div>
<div>I would appreciate any tips you can give on making the attached script more efficient.</div>
<div><br>
</div>
<div>One idea I have is to use the bin_sum function and just do a running mean instead of saving the daily means. </div>
</div>

Hi Mary,
<div><br>

<div>I’m still working on this. I’ve not set the <font size="2">tfDoNDCOverlay and what I realised is that my model doesn’t have a square grid, i.e., the </font></div>
<div><font size="2">spacing in the lat and lon directions are slightly different. I’m regridding instead to a square grid and then binning the MHS data to the square grid. If this fails I’ll plot the lat and lon values as you suggested and contact you again

<div>Hi,</div>

</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>
