<p>Dear Eric, as far as I understand that instruction only will cause to repeat the same calculation 12 times<br>
Best regards<br>
Luis</p>

<div><div style="font-size:12pt;font-family:arial,helvetica,sans-serif">Hello Luis,<div><br></div><div>The 'set t 1 12' line is definitely needed. It sets the dimension environment to vary in time (monthly in this case) over one year (1979) from January to December, which is what you need to do before calculating a monthly climatology. If the monthly dataset began in December rather than January, use 'set t 2 13' instead.</div>
