[ncl-talk] phase difference in plots

[Alan Brammer]

anomexel=exel
anomel=el - meanClimatology
anomexla=exla-meanClimatology

These lines do not copy the metadata.  You should do a
copy_VarCoords(meanClimatology, anomel)  for each respective variable.

As such, you will have seen a warning about a lack of coordinates when
plotting. NCL will have tried to guess at the location data probably 0:360
but your data is likely -180:180 thus the resulting plot is 180° off.

Pay attention to any warnings that NCL produces, it's pretty easy to have
scripts run without any undesired print outs (don't just ignore them).

Also printVarSummary(anomel) will show a complete lack of any metadata.
Always a good starting point when something isn't quite right.

Good luck,

Alan
