NWP Containers Online Tutorial | Setting Up a New Experiment > Pulling data from AWS

Pulling data from Amazon S3 bucket

In this example, we will be retrieving 0.25° Global Forecast System (GFS) data from a publicly available Amazon Simple Storage Service (S3) bucket and storing it on our local filesystem, where it will be mounted for use in the Docker-space. The case is initialized at 00 UTC on 20210601 out to 24 hours in 3-hr increments.

To run the example case, first we need to set some variables and create directories that will be used for this specific example.

Then, you should set up the variables and directories for the experiment (spring_wx):

The GFS data needs to be downloaded into the appropriate directory, so we need to navigate to:

Next, run a script to pull GFS data for a specific initialization time (YYYYMMDDHH), maximum forecast length (HH), and increment of data (HH). For example:

Run NWP initialization components (WPS, real.exe)

As with the provided canned cases, the first step in the NWP workflow will be to create the initial and boundary conditions for running the WRF model. This will be done using WPS and real.exe.

These commands are the same as the canned cases, with some case-specific updates to account for pointing to the appropriate scripts directory and name of the container.
