<br clear="all">Hai,<br><br>I was calculating daily climatology for 30 year ncep wind from 1979 to 2008 and i encountered a problem. As per grads tutorial i have given the following commands<br><br>'reinit'<br>'sdfopen /media/MEGA2/wind/ncep/uwind/level/u200/<a href="http://u200-1979-2009.nc">u200-1979-2009.nc</a>'<br>
'set grads off'<br>'set lat -20 40'<br>'set lon 30 180'<br>'set map 1 1 8'<br><br>'set t 1 365'<br>'define uclim = ave(uwnd, t+0,t+10958,365)'<br><br>and i am getting uclim properly<br>
<br>but inorder to make it a climatological variable i used 'modify' function<br><br>'modify uclim seasonal'<br><br>then i got error<br><br>MODIFY Error: Invalid time scaling in defined variable, then i used<br>
<br>'modify uclim diurnal'<br><br>will say 'Defined variable is now climatological' but is showing same pattern for all the days<br><br>As grads tutorial says <br><br><code>seasonal </code><span class="plaintext">- For creating
monthly or multi-monthly climatologies</span><br><code>diurnal </code><span class="plaintext">- For creating
climatologies over a time period less than a day</span><br><br>ie there are only options for monthly or less than a day calculation. what is the option for finding daily climatology using this method<br><br><br>-- <br>
