[ncl-talk] calculate monthly anomaly

[Dennis Shea]

(1) you can copy dim_pad; extract just the section for your dimensionality; translate to use 'else if' rather than 'elseif'

Not that difficult to do.

I am trying to calculate monthly climatology and anomaly for each of the months. But as I am using either clmMonLLT or calcMonAnomLLT it needs "time dimension must be multiple of 12". Is there any other function available to calculate anomalies when time dimension is not exactly divisible by 12.
