ERROR: No TRUELAT1 specified for Lambert conformal projection.

[mcjason413]

I'm using mercator projection, however, when executing geogrid.exe, it shows this error "ERROR: No TRUELAT1 specified for Lambert conformal projection."

This error has nothing to do with my settings. Please advise, thanks!

please send me your namelist.wps to take a look. Thanks.

I copied another namelist and modified it, then there is no such problem. However, I still cannot figure out why the previous error showed like that.

 

[Ming Chen]

Have you compared the two namelist.wps you used? Is there any difference between the two? There must be a reason why the previous run complained of the truelat setting (I suppose you run with the same georgic.exe).

 

[mcjason413]

Yup, I just found that the value of "truelat1" was set as "2.0" instead of "2" in the previous namelist.

 

[Ming Chen]

It is possibly because the specified value of truelat in the previous namelist.wps is integer, while the WPS program expects a real type. However, this still doesn't explain why the code complains of a variable that is not used based on the namelist setting.
