James,<br>If your list of times is truly irregular (i.e., there is no mathematical pattern that can be used to shorthand the list, even if pointwise) then you will have to list out each of the times or files to get your average.<br>

you misunderstand me. I have two files, <a href="http://uwind.nc" target="_blank">uwind.nc</a>, <a href="http://vwind.nc" target="_blank">vwind.nc</a> and I want to produce a spatial plot (lon = 35 68, lat = 0 75) of u;v for each of these time values and average out the result. I have more lists, so typing out define for each time value and then using x+y+...+z/n is not really a good option<br>
<br>can anyone help me out?<br><br><div class="gmail_quote">On 17 May 2011 17:51, saeed bayat <span dir="ltr"><<a href="mailto:saeedbayat7276@gmail.com" target="_blank">saeedbayat7276@gmail.com</a>></span> wrote:<br>

Hi James<br>If you work in linux environment, you can use these command for create a file with time series or a file that is average of several files: <br>for make a file include average all of files: ncra <a href="http://1.nc" target="_blank">1.nc</a> <a href="http://2.nc" target="_blank">2.nc</a> 3 .nc <a href="http://4.nc" target="_blank">4.nc</a> <a href="http://5.nc" target="_blank">5.nc</a> <a href="http://output.nc" target="_blank">output.nc</a><br>
for create a file include time series of all files: ncrcat <a href="http://1.nc" target="_blank">1.nc</a> <a href="http://2.nc" target="_blank">2.nc</a> <a href="http://3.nc" target="_blank">3.nc</a> <a href="http://4.nc" target="_blank">4.nc</a> <a href="http://output.nc" target="_blank">output.nc</a><br>
