Numerical Weather Prediction on AWS with WRF

Storage options

After creating or running any case, and to reuse or store this block, we can simply unmount it ($ sudo umount -d /dev/nvme1n1), detach the volume and create a snapshot from the console volume menu.

Also, it is important to notice that we did not select ‘Delete on Termination’ previously so terminating the instance will not delete the volume and the meter will keep running until its deletion from the console or alternatively the CLI.
S3 is more adequate for long-term storage, backup, and access to large databases. Among the latter, the OpenData_list file provides a list with available datasets for WRF use. To retrieve this data, the command ‘aws sp cp s3://ncar-cesm-lens//filename –no-content’ will copy it to your instance. To access non-public buckets belonging to your organization, it is necessary to configure your credentials with $ aws configure, which will ask for the IAM credentials (aws_access_key_id and aws_secret_access_key). There is plenty of online help and discussions on AWS S3, plus the official documentation (, which is voluminous.
