What is the license for Dataset CFD Meshes?

Hi, I'm studying Machine Learning.

What is the license for the dataset downloaded by the following shell script?
https://github.com/google-deepmind/deepmind-research/blob/master/meshgraphnets/download_dataset.sh

I understand that the dataset is stored in the following location:
https://storage.googleapis.com/dm-meshgraphnets

I'm particularly concerned about whether the "cylinder_flow" dataset can be used commercially.

Best regards.
