Matlab presents several functions and library packages to read and write NetCDF files: netcdf.open('file_name.nc') #open NetCDF file If you need an example on how to open and visualize NetCDF files with R, check out this article! You can find a detailed documentation and examples of NetCDF files in R here. It's recommended to use the R library(ncdf4) : it allows to read, write and create NetCDF files, either version 3 or version 4. We will mostly use the xarray module to open and plot our data, with the help of matplotlib to embellish our georeferenced plots. In this article we introduce an example on how to access and visualize the global temperature for year of 2021, from the Global Ocean 1/12° Physics Analysis and Forecast updated Daily Marine product. Several packages are available in Python to obtain and open NetCDF data. Let's focus on some examples of code languages to open a NetCDF file: Some packages have been developed in various programming languages to open, manipulate and plot the variables contained in a NetCDF (as Python, R/Rstudio and Matlab). QGIS is a free and open source desktop geographic information system application that allows you to visualize, edit and analyze geospatial data. In this article an example of application with sea ice concentration and thickness data is available. It allows to open NetCDF files and create simple graphics and animations in few clicks (to learn more: How to explore Copernicus Marine products with PANOPLY?)ĮSA Sentinel free application platform which offers processing and analysis capacities for the use of earth observation data.
You will find here a tutorial video showing and explaining some of the most used methods, as well as list of few suggestions of coding packages and software tools, all of them allowing a complete analysis and manipulation of this file format.īelow are several examples of methods for opening and viewing Copernicus Marine data within Graphic User Interfaces and softwares:įree software, developed and released by NASA. There are several methods to open and visualize a NetCDF file, either via Graphic User Interface (GUI) or Command Lines (CLI). nc) format, the mostly used for scientific data, enables to contain and share a lot of georeferenced information in a relatively small file size. The standard format for Copernicus Marine data is the NetCDF (. This article is organized as follows (4 min read):
