You can easily do that either with NCO and the command <font face="Menlo" class="">ncrcat</font> (see here <a href="http://research.jisao.washington.edu/data_sets/nco/#example8" class="">http://research.jisao.washington.edu/data_sets/nco/#example8</a>) or using CDO with the <font face="Menlo" class="">merge</font> option (see here for the complete guide <a href="https://www.rsmas.miami.edu/users/rajib/cdo.pdf" class="">https://www.rsmas.miami.edu/users/rajib/cdo.pdf</a>). These methods will work <b class="">without</b> problems as long as you have a well-defined time coordinate in your files and the vertical levels are always the same. </div><div class="">Cheers</div><div class=""><div class="">

These retrievals of temperature, moisture, etc, are in units of (lev,time) in each file. I want to join all of the files together so that I can compare the data to dropsondes.

It is because my leftmost dimension is not time (level instead), which is required to merge them together. Is there any workaround to do this, like reorder when reading in, with what format my data is in? Basically I want to make my code portable so I can join any number of files for a particular storm case, since not all cases have the same amount of time retrievals.</font></div><div style="margin: 0px; line-height: normal;" class=""><font face="arial, helvetica, sans-serif" class=""><br class=""></font></div><div style="margin: 0px; line-height: normal;" class=""><font face="arial, helvetica, sans-serif" class="">I also attached an ncl_filedump output of the format of the data I am reading.
