我在python netcdf上找到了此问题的答案:制作了所有变量和属性的一个副本,但一个副本,但我需要对其进行更改以使其与我的python / netCDF4版本(Python 2.7.6 / 1.0.4)一起使用。如果需要添加或减去元素,则可以进行适当的修改。
import netCDF4 as nc
def create_file_from_source(src_file, trg_file):
src = nc.Dataset(src_file)
trg = nc.Dataset(trg_file, mode='w')
# Create the dimensions of the file
for name, dim in src.dimensions.items():
trg.createDimension(name, len(dim) if not dim.isunlimited() else None)
# Copy the global attributes
trg.setncatts({a:src.getncattr(a) for a in src.ncattrs()})
# Create the variables in the file
for name, var in src.variables.items():
trg.createVariable(name, var.dtype, var.dimensions)
# Copy the variable attributes
trg.variables[name].setncatts({a:var.getncattr(a) for a in var.ncattrs()})
# Copy the variables values (as 'f4' eventually)
trg.variables[name][:] = src.variables[name][:]
# Save the file
trg.close()
create_file_from_source('in.nc', 'out.nc')
此代码段已经过测试。
