[ncl-talk] Coordinate syronising error

[Dennis Shea]

I don't have the time to look at your script right now.

However, The lat/lon ranges are different.

In particular the longitudes. Likely, you will have to make the longitudes
both be (nominally) 0-to-360 or -180-to180
You can use *lonFlip*
<http://www.ncl.ucar.edu/Document/Functions/Contributed/lonFlip.shtml>  to
accomplish this.

Variable: co_model
Dimensions and sizes:   [time | 12] x [lev | 56] x [lat | 192] x [lon | 288]
Coordinates:
            time: [  31.. 365]
            lev: [1.867879997007549..992.5000106104562]

*            lat: [ -90..  90]            lon: [   0..358.75*]

Variable: cocol_retr
Dimensions and sizes:   [ncl_join | 12] x [XDim_MOP03 | 360] x [YDim_MOP03
| 180]
Coordinates:

*          XDim_MOP03: [-179.5..179.5]            YDim_MOP03: [-89.5..89.5]*
