netcdf.copyAtt(ncidIn, varidIn, attname, ncidOut, varidOut)
| Parameter | Description |
|---|---|
| ncid | Open netCDF file or group identifier. |
| varid | Variable identifier, or NC_GLOBAL for a global attribute. |
| attname | Attribute name. |
| attvalue | Attribute value. |
| Parameter | Description |
|---|---|
| none | This function does not return a value. |
netcdf.copyAtt exposes low-level attribute operations.
Attributes store metadata such as units, titles, comments, scale factors, and valid ranges.
