Copy Attribute from One NetCDF to Another
Copy attribute from one NetCDF to another.
att.copy.nc(ncfile.in, variable.in, attribute, ncfile.out, variable.out)
ncfile.in |
Object of class " |
variable.in |
ID or name of the variable in the input NetCDF dataset from which the attribute will be copied, or |
attribute |
Name or ID of the attribute in the input NetCDF dataset to be copied. |
ncfile.out |
Object of class " |
variable.out |
ID or name of the variable in the output NetCDF dataset to which the attribute will be copied, or |
This function copies an attribute from one open NetCDF dataset to another. It can also be used to copy an attribute from one variable to another within the same NetCDF dataset.

## Create two new NetCDF datasets and define two dimensions
file1 <- tempfile("att.copy_", fileext=".nc")
file2 <- tempfile("att.copy_", fileext=".nc")
nc.1 <- create.nc(file1)
nc.2 <- create.nc(file2)
dim.def.nc(nc.1, "station", 5)
dim.def.nc(nc.1, "time", unlim=TRUE)
dim.def.nc(nc.2, "station", 5)
dim.def.nc(nc.2, "time", unlim=TRUE)
## Create two variables, one as coordinate variable
var.def.nc(nc.1, "time", "NC_INT", "time")
var.def.nc(nc.1, "temperature", "NC_DOUBLE", c(0,1))
var.def.nc(nc.2, "time", "NC_INT", "time")
var.def.nc(nc.2, "temperature", "NC_DOUBLE", c(0,1))
## Put some attributes to the first dataset
att.put.nc(nc.1, "temperature", "_FillValue", "NC_DOUBLE", -99999.9)
att.put.nc(nc.1, "NC_GLOBAL", "title", "NC_CHAR", "Data from Foo")
## Copy the attributes to the second dataset
att.copy.nc(nc.1, 1, 0, nc.2, 1)
att.copy.nc(nc.1, "NC_GLOBAL", "title", nc.2, "NC_GLOBAL")
close.nc(nc.1)
close.nc(nc.2)
