Import type NETCDF-CF_GRID_S3 imports grids from nc files stored in S3 buckets.
To find the URL’s to the required S3 buckets and to list the nc files stored in the buckets, the Amazon Web Services (AWS) are used.
The listed nc files are read using the existing import type NETCDF-CF_GRID . It means that all features of NETCDF-CF_GRID are also available for reading from S3 buckets.
