Hi Atul,<br>
<br>
do you want to calculate the avg and the stddev on the longitude
coordinate? The functions dim_avg and dim_stddev do the calculations
on the right- most dimension. If you want to do it on the time
dimension then you should use dim_avg_n and dim_stddev_n functions.<br>
<br>
To prevent division by 0 you can use the where function. Searching
the internet will give you some ncl-talk answers to this issue.<br>
