<div dir="ltr">Hi Debasish,<br><br>This is an HDF-EOS2 file, which you can see if you do an ncl_filedump on the file and look at the top part of the output:<br><br><font face="monospace, monospace">Variable: f<br>Type: file<br>filename: MYDAODHD.A2017305.0000.061.NRT<br>path: MYDAODHD.A2017305.0000.061.NRT.hdf<br> file global attributes:<br> HDFEOSVersion : HDFEOS_V2.19</font><br><br>Try adding ".he2" to the end of the filename in your script. This will tell NCL to try opening the file as an HDF-EOS2 file:<br><br><font face="monospace, monospace"> diri = "./November2017/1/"<br> fili = "MYDAODHD.A2017305.0000.061.NRT.hdf.<b>he2</b>"<br><div class="gmail_default" style="font-size:small;display:inline"> </div>pthi = diri+fili<br> w = addfile(pthi,"r")</font><br><br>It is not necessary to rename the file itself. The "addfile" command will first look for a file called "MYDAODHD.A2017305.0000.061.NRT.hdf.he2", and if it can't find that, it will look for the file "MYDAODHD.A2017305.0000.061.NRT.hdf", but will try to open it as an HDF-EOS2 file.<br><br><div>Once you do this, the <div class="gmail_default" style="font-size:small;display:inline">file will look much more reasonable.</div></div><br>--Mary
