The OASIS Historical Data Downloader uses Amazon Web Services (AWS) S3 to store all data files. As such, users are required to create and set up their own AWS account for personal or organizational usage.

• AWS credentials are not required to search the repository but are required to download data files.
• Users are responsible for any costs associated with data downloads.
• Please refer to the AWS “Requester Pays” bucket documentation for more details on how download charges are applied.

Please note that in order to download data, users must have an active AWS account. This requirement ensures secure access and proper integration with cloud-based services. Details regarding this prerequisite are included in the user guide. We encourage all prospective users to verify their AWS credentials in advance to ensure smooth customer experience.

We encourage users to explore the new tool and take advantage of its improved features. Your feedback is valuable. Please use the feedback icon located on the left side of the tool interface to share comments or report any issues.
