NetCDF (network Common Data Form) is a file format for storing multidimensional scientific data (variables) such as temperature, humidity, pressure, wind speed, and direction. Each of these variables can be displayed through a dimension (such as time) in ArcGIS by making a layer or table view from the netCDF file.

Where can I learn more about netCDF data?
The primary source of information about netCDF data is the Unidata community.
Many organizations and scientific groups in different countries have adopted netCDF as a standard way to represent some forms of scientific data.
