I have a large set of files (time,level,lat,lon and 6 hourly) that span multiple years, but they are not divided nicely into months/years. I only want to read in one month at a time (and only 00Z), which in some cases, spans only one file, but in other cases
spans two.
<div><br>
</div>
<div>My code works perfectly for the months that come from only one file, but I get a “Segmentation fault (core dumped)” when the month spans two files. See brief code example below (happy to send more and actual files if needed).</div>
<div><br>
</div>
<div>example files: </div>
<div><a href="http://temp_195001010600-195007010000.nc" target="_blank">temp_195001010600-<wbr>195007010000.nc</a></div>
<div><a href="http://temp_195007010600-195107010000.nc" target="_blank">temp_195007010600-<wbr>195107010000.nc</a></div>
<div><br>
</div>
<div>example code snipet:</div>
<div><br>
</div>
<div>…….</div>
<div>
<div>all_files = systemfunc ("ls “+in_path+"temp_195*.nc")</div>
<div>f = addfiles (all_files, "r") </div>
<div><br>
</div>
</div>
<div>
<div>ListSetType(f,"cat")</div>
<div>time = f[:]->time</div>
<div><br>
</div>
<div>utc_date = cd_calendar(time, 0)</div>
<div>yr<span style="white-space:pre-wrap"> </span>=<span style="white-space:pre-wrap">
</span>tointeger(utc_date(:,0))</div>
<div>mm<span style="white-space:pre-wrap"> </span>=<span style="white-space:pre-wrap">
</span>tointeger(utc_date(:,1))</div>
<div>hour = tointeger(utc_date(:,3))</div>
</div>
<div><br>
</div>
<div>index = ind(yr.eq.1950 .and. mm.eq.7 .and. hour.eq.00)<span style="white-space:pre-wrap">
</span></div>
<div><br>
</div>
<div>
<div>ListSetType(f,"cat")<span style="white-space:pre-wrap">
</span></div>
<div>ta = f[:]->ta(index,:,:,:)<span style="white-space:pre-wrap">
</span></div>
…………</div>
<div><br>
</div>
<div>As I mentioned, this works great if mm.eq.1, mm.eq.2 etc., but not when mm.eq.7. When reading in ta(index,:,:,:) I get the segmentation fault.<span style="white-space:pre-wrap">
