You can make use of while loops and output the averages, that is one record for each decaded totaling 20 as follows. Your averages will be output by the fwrite command, you will need a control file to read it.<br>

'set gxout fwrite'<br>
'set fwrite decade_data.dat'<br>
is = 1<br>
while(is < = 2400)<br>

'set t 'is<br>
'd tloop(ave(temperature, t+0, t+119))'<br>
'c' <br>
<br>
is = is + 120<br>

<p>Hi lopez, </p>
<p>Thanks for your input but I don't want runing mean average based on 10 years, instead I want decadal average such that after getting averaged value for first 10 years (average of 1 to 120 months) it should give value for next 10 years (average of 121 to
240th time) and so on.</p>
<p>Thanks,</p>
<p>Mubashar</p>

Dear Mubashar,<br>
<br>
You can use the tloop function in conjunction with the ave function as follows:<br>
<br>
set t 61 2340<br>
d tloop(ave(temperature,t-60,t+60))<br>
<br>
This will create an average for decadal timescales.<br>
Note, the time start at month 61 = beginning of year 6 and ends at month 2340 = 5 years prior to year 200 of your data.<br>
<br>
At the end you should have a monthly time series of decadal averaged quantity.<br>
<br>
Best,<br>

<br>
Dear Grads Users,<br>
<br>
I have monthly time series data (let say surface temperature) and<br>
wanted to plot it on decadal average basis. I mean first value of plot<br>
will be average of first 120 months and the next value of my plot will<br>
be average of next 120 months and so on. In total for 200 years I<br>
should get 20 value in plot. How can I do that? Y axis will be decadal<br>
average temperature values and x axis can be labelled 1, 2, 3 up 20<br>
instead of months or years.<br>
<br>
Thanks,<br>
<br>
Mubashar<br>
