How do I open netCDF data in python?

Reading netCDF data using Python

  1. from netCDF4 import Dataset import numpy as np.
  2. my_example_nc_file = ‘/Users/jhamman/Desktop/my_example_nc_data.nc’ fh = Dataset(my_example_nc_file, mode=’r’)
  3. lons = fh.variables[‘lon’][:] lats = fh.variables[‘lat’][:] tmax = fh.variables[‘Tmax’][:] tmax_units = fh.variables[‘Tmax’].units.

What is python netcdf4?

netcdf4-python is a Python interface to the netCDF C library. This module can read and write files in both the new netCDF 4 and the old netCDF 3 format, and can create files that are readable by HDF5 clients. The API modelled after Scientific. IO. NetCDF, and should be familiar to users of that module.

What is netcdf4?

NetCDF-4 (Network Common Data Form, version 4) Description. NetCDF is a set of software libraries and self-describing, machine-independent data formats for array-oriented scientific data.

How do I read a .netcdf4 file?

To read a netCDF file of known structure, you need to:

  1. open the file – Specify the file name and whether you want read-write or read-only access.
  2. read variable or attribute data – Read the data or attributes of interest.
  3. close the file – Release all resources associated with this file.

How do you plot a netCDF in Python?

Plot netCDF data on a map

  1. Plot netCDF data on a map.
  2. First we need to import netCDF4-python, Numpy, Matplotlib for plotting, and Basemap for the map.
  3. Load in the netCDF file.
  4. Read the variables from the netCDF file and assign them to Python variables.

Where is netCDF installed?

#The NetCDF Fortran library path is where the library file libnetcdff. a or libnetcdff.so can be found (which may differ from the C library path if a shared installation is not possible on your system, see here) (default /usr/local/lib; at CEH I have /usr/lib64).

Is netCDF a raster?

Using the Make NetCDF Raster Layer tool from the Multidimension Tools toolbox, you can create a raster layer from a netCDF variable. The output raster layer can be used in other tools that accept rasters as input for further analysis.

Is netCDF a binary?

The original netCDF binary format (released in 1990, now known as “netCDF classic format”) is still widely used across the world and continues to be fully supported in all netCDF releases.

How do I view netCDF files?

NetCDF files usually have the extension . nc. To read NetCDF files there are tools with a graphical interface like Matlab, IDL, ArcGIS, NCView, Xconv and developer (programming) tools like the Unidata NetCDF4 module for Python and Xarray.

How do I view NC files?

You can use programming languages or windows software. If you want just to view nc file and display it, Panoply is the best and you can use free version of Netcdf Extractor for viewing. But, if you want to extract time series from one file or many files, you can use Netcdf Extractor and do it easily.
