Get parameters from NetCDF exported from EE

Get parameters from NetCDF exported from EE

Once the model has output, we can export the model output to NetCDF files. How to export to NetCDF files has been introduced in Export to NetCDF files. Get parameters from NetCDF exported from EE#Figure 1 shows a form of exporting to NetCDF files.

This tutorial will provide information on the main parameters extracted from NetCDF files using Python script.

Get parameters from NetCDF exported from EE#Table 1 shows the information on parameters obtained from the NetCDF files.
