We regret to inform you that the BSISO (Boreal Summer Intraseasonal Oscillation)
Monitoring, Prediction, and Verification Data Service has been temporarily paused starting from the June 3rd dataset due to an unexpected technical issue with our external data source.

- Affected Service: BSISO Monitoring, Prediction, and Verification Data Services

- Period of Interruption: June 3, 2026 ~ Until the source data is restored

- Cause of Interruption: A technical outage at the primary source supplying the NOAA CPC Blended OLR dataset, leading to a delay in automated data ingestion.

- Current Status: We are actively communicating with the NOAA PSL Data Team to monitor the resolution of their system outage. As soon as the data availability is restored by NOAA, we will immediately back up the missing files and resume our operational data production.

We sincerely apologize for any inconvenience this may cause to your operations. We are doing our best to ensure the service is restored as promptly as possible.
For any urgent inquiries, please contact Help Desk or the Climate Prediction Department.

Thank you for your cooperation and understanding.
