<p>Hi Gisele,</p>
<p>You may try the following:</p>
<p>1 - Cut both files in lat/lon (same lat/lon for both) and if they have the same spatial resolution (if the regrid function worked ok) they will have the same quantities of points in x and y.</p>
<p>What kind of data are you using? Netcdf, binary or any other?</p>
<p>Paulo.</p>

<blockquote style="border-left: 2px solid #6868cc; margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br />Hello users!!<br /><br />I have two files with different resolutions and I want to compare the <br />differences between them. I used the regrid function to take both in the <br />same resolution. The regrided file is just one hour, while in the other <br />I have a range of 22 times. I want to compare just the hour of the <br />first, so I have two problems when I try to do that: an error of <br />resolution, because the two files don't have the same quantity of points <br />in x and y and I don't know how to set the time just for the second and <br />then calculate the difference.<br /><br />Please any help will be nice!<br /><br />Thanks,<br />Gisele<br /><br /><br />-- <br />Msc.
