[ncl-talk] Coordinate syronising error

[Najib Yusuf]

No Rashed, could it be interchanged with longitude?

 Dear Dennis,
Thank you for this quick response. I have effected the suggestion, the printVarSummary is:

However, when I run I get similar error:fatal:NclOneDValGetClosestIndex: finish coordinate index out of range, can't continuefatal:Could not obtain coordinate indexes, unable to perform subscriptfatal:["Execute.c":8637]:Execute: Error occurred at or near line 172 in file Annualaverage_MOPITTCO_nyg_modified.ncl
I know you are busy, kindly spare some time to assist me look at the script as you use to.
Thank you sir.

 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-to180You can use lonFlip  to accomplish this.

Dear NCL users,
I am comparing CO from MOPITT satellite retrieval and model CAM output with averaging kernel been considered. I am having trouble synchronising the coordinates amd the error is: fatal:NclOneDValGetClosestIndex: finish coordinate index out of range, can't continuefatal:Could not obtain coordinate indexes, unable to perform subscriptfatal:["Execute.c":8637]:Execute: Error occurred at or near line 165 in file Annualaverage_MOPITTCO_nyg_modified.ncl ( under:  Collect equivalent profile)
I look around NCL examples but couldn't figure out how to resolve the issue and get the plot. Kindly assist to figure out the solution to this. The script Annualaverage_MOPITTCO_nyg_modified.ncl and the run CO_MOPITT_MODEL_Comparison_run are attached. 
Thank you for your support._______________________________________________
