## Current Status

- 2 AIRS evolution risks recently retired
- Data Access Performance
- 2+ TB/day distributed from L1 archive server
- Throughput Capacity
- L1 @ 25X, L2/3 @ 12X
- V005 Reprocessing Status

## Conclusion

- All L2/L3 V004 data migrated from ECS to S4PA
- All V005 data flow into S4PA
- All data interfaces successfully transitioned from ECS to S4PA
- All public data in S4PA available through user interfaces
- _ECS no longer needed or used for AIRS data_
