Re: How to read a variable with "\(" in name?

Thank you very much for your helpfulness, Wei and Dennis!

I changed "varname" as Wei suggested and it worked!
Now NCL reads the variable.

Many thanks!

Best regards,
Susanna

Susanna,

Try change:

    varname = "cos\(SZA\)"
    cos_SZA = f->$varname$

to:

    varname = "cos(SZA)"
    cos_SZA = f->$varname$

You may try ncl_filedump first to check out the variable names in NCL.

Dear all,

I'm trying to read from a NetCDF file a variable named "cos\(SZA\)".
I obtained the name from the header of the file; the variable refers to the cosine of the Solar Zenith Angle.

Using ncdump -v cos\(SZA\) and the Panoply software, I checked that the variable contains data and that these values are consistent (positive, lower than 1).

I tried using the $…$ syntax since I saw that you use this method for variable names that contain "-" symbols. (from the NCL-Talk Archives, message: "Re: Read variable with parenthesis in name?").

    varname = "cos\(SZA\)"
    cos_SZA = f->$varname$

Unfortunately, it didn't work for my case and I got the following error message (same as without the $…$ syntax):

fatal:["Execute.c":5900]:variable (cos\(SZA\)) is not in file (f)

Does anyone have a suggestion to figure out this issue?

Many thanks for your help!

Best,
Susanna
