Dear all,<br><br>How to get the mean of a specific time. I mean I have monthly data of 10 years. I need to obtain the mean of each month. I used 'cdo -r ymeanmonth <a href="http://input.nc">input.nc</a> <a href="http://output.nc">output.nc</a>' but my computer says cannot allocate memory since the file is pretty big in size (20 Gb)<br>
<br>Then I tried to use GrADS but cannot find the appropriate command.<br>I will take one by one the mean of each month, so for example for october<br><br>if I do define oct=mean (var, t=1, t=12) it will give me the mean of 12 month but I do not need that but I need the mean of all october of 10 years of the monthly data of 10 years.<br>
<br>How to get each october?<br>Something like 'define oct=mean(var,t=10,t=22,t=34,t=46,t=58,t=71,t=83,t=95,t=107,t=119)<br><br>I hope you get the idea<br><br>Serge<br><br clear="all"><br>-- <br>Serge<br>
