[ncl-talk] check_for_y_lat_coord

[Ehsan Taghizadeh]

 Dear Rick,Thank you so much for your helpful reply. I've uncommented the following lines, however it didn't change the result:
   tp&latitude at units="degrees_north"   tp&longitude at units="degrees_east"
I've also attached .tar.gz file of data, if it could help.SincerelyEhsan    On Tuesday, February 26, 2019, 1:40:51 AM GMT+3:30, Rick Brownrigg <brownrig at ucar.edu> wrote:  
 
 Hi,
I don't have a means to open the .rar file you sent, but it sounds like its the latitude and longitude variables in the file are what do not have the units attribute.  From your printFileSummary(tp):
Variable: tpType: floatTotal Size: 3755712 bytes            938928 valuesNumber of Dimensions: 3Dimensions and sizes:   [time | 1262] x [latitude | 24] x [longitude | 31]Coordinates:            time: [1008072..1038336]            latitude: [41.25..24]            longitude: [42.75..65.25]
we can see there's already coordinates attached to tp. Perhaps try verifying that longitude and latitude in your file are lacking units, and if so, add them to those variables -- I don't think you want to do what you found on the link you cited.
Hope that helps...Rick

Dears,I've tried to plot precipitation data from ERA-Interim with the attached script.However after trying this I encountered the following errors:

I've found this link (https://www.ncl.ucar.edu/Document/Graphics/error_msg.shtml), and based on it I tried something like these:   tp!0="time"   tp!1="lat"   tp!2="lon"   tp&lat at units="degrees_north"   tp&lon at units="degrees_east"
But unfortunately they doesn't help!May I ask your help to plot precipitation data from ERA-Interim. I've just to say I did a processing to original ERA-Interim data to obtain daily precipitation (It has been done before with ncl-talk help). Attached are the script and data.Any help would be appreciated.
