A quick tour of netCDF data

NetCDF (network Common Data Form) is a file format designed to support the creation, access, and sharing of scientific data. It is used extensively in the atmospheric and oceanographic communities to store variables, such as temperature, pressure, wind speed, and wave height.

NetCDF data are:

  • Self-describing, meaning that a netCDF file includes information about the data it contains, such as when data elements were captured and what units of measurement were used.
  • Portable, or cross-platform, in that a netCDF file created on one type of operating system can often be read by software on another type of operating system.
  • Scalable, such that a small subset of a large netCDF file can be accessed efficiently without reading the entire file.

Temperature on the left and Pressure at specific locations on the right
Examples of netCDF data: Left—Temperature; Right—Pressure at specific locations.

ArcGIS Pro reads netCDF files natively, providing immediate access to the data without the need for data conversion or import. You can use the Make NetCDF Raster Layer, Make NetCDF Feature Layer, and Make NetCDF Table View tools from the Multidimension Tools toolbox to create a raster layer, a feature layer, and a table view, respectively, from a netCDF file.

Following is the list of available tools for working with netCDF data.

You can add a classic netCDF raster layer or a multidimensional raster layer using the Multidimensional Raster Layer Multidimensional raster layer option in the drop-down list for the Add Data button Add Data. For more details, please refer to Working with a multidimensional raster layer.
