The above *warning* is likely due to one or more time
series having all the same value. EG: a value of 0.0
over desert areas. The correlation coef is derived
by dividing be the standard deviation, If all values
are the same, then the std. dev. is also 0.0.

I am not sure what you are doing here:

ccf_ssum = esccr(wspd_ssum(lat|:,lon|:,time|:) \
,rain_ssum(lat|:,lon|:,time|:),0) \
/(stddevws_ssum*stddevrn_ssum)

The following returns a 3d array

ccr_3d = esccr(wspd_ssum(lat|:,lon|:,time|:) \ ; (lat,lon,mxlag)
,rain_ssum(lat|:,lon|:,time|:),0)

The denominator is 2d ... hence the error msg.

```----
I suggest using  escorc
http://www.ncl.ucar.edu/Document/Functions/Built-in/escorc.shtml
ccf_ssum = escorc(wspd_ssum(lat|:,lon|:,time|:)  \
,rain_ssum(lat|:,lon|:,time|:)) \
/(stddevws_ssum*stddevrn_ssum)
