6. Data Processing and Distribution (Today)
NDE (NPP Data Exploitation) provides NPP data and derived products.
GEODIST provides McIDAS products via ADDE.
McIDAS products are satellite imagery and primarily GOES derived products
DDS (Data Distribution Server) provides all other non-McIDAS operational products.
GINI (GOES Ingest NOAAPORT Interface) provides data to the NWS AWIPS Satellite Broadcast Network (SBN) and to NOAAPORT.  
Existing data access process:
Users complete a standard data access request form found at:
URL:
Technical assessment conducted to ensure system and infrastructure resources are available to service the request.
Access is reviewed and adjudicated by the Data Access Review Board to validate the near real-time access requirement.
Data activation and subscriptions are actively managed by OSPO/ESPC personnel.

7. Data Access Policy: http://www. ospo. noaa
Requestors must:
Have an operational need for near real-time data
Agree to adhere to the rules of behavior on the Data Access Request form
Understand that requests may be prioritized due to data volume issues.
Send request to:

8. Processing and Distribution (near Future) - PDA
Purpose of the Production Distribution and Access (PDA) system is to serve as the NESDIS enterprise distribution system for our near real-time users.
All near real-time distribution except for McIDAS will be migrated to PDA – phased approach (new missions and then current missions).
McIDAS ADDE access will remain on GEODIST systems for the foreseeable future.
GOES-R products will be provided to AWIPS2/Satellite Broadcast Network (SBN), GOES Re-Broadcast (GRB) and the primary PDA system at NSOF.
S-NPP/JPSS products will be provided via PDA.
PDA is being developed for OSPO by the Office of Satellite Ground Services (OSGS).
PDA Distribution Service Improvements:
User managed subscriptions
User managed search and tailoring
Enhanced security controls / transfer protocols
Enhanced reporting and control for system optimization
Ability to handle large data volumes

9. High Data Volumes - Example
Example of bandwidth capacity needed to transfer one full orbit of uncompressed S-NPP data as a function of time.
Key points:
Data transfers can only go as fast as the slowest link speed.
Accessing new mission data via terrestrial communication circuits require significant bandwidth capacity increase.
Vast amounts of new data require capacity changes by provider and end user.
Need 1 Gbps of available bandwidth capacity to transfer one full orbit of data in 38 mins

10. PDA Systems There are three PDA instantiations:
Full Operational System at NSOF
S-NPP/JPSS, GOES-R and current mission data
Test system at NSOF
Internal test system only
Smaller capacity operational contingency system at Consolidated Back-Up (Fairmont, West Virginia)
S-NPP/JPSS data (prime mission sensor only)
GOES-R data only available via GRB (GOES Re-Broadcast) and AWIPS

11. Future Contingency Operations Note
In the event of an outage at the primary Facility (NSOF in Suitland, MD), PDA access is transferred to the Consolidated Back-up in Fairmont, West Virginia, to support only the JPSS/S-NPP mission.
Data fail-over requirement is under 12 hours.
Just the JPSS primary mission sensor data will be available, since the backup system is smaller scale than the operational system at NSOF.
Supports both full and partial failover scenarios
i.e. GOES-R can be nominal a NSOF while JPSS is failed over to CBU
This flexibility requires different network addresses at NSOF and CBU, therefore Pull users will need to change to CBU if needed.

12. PDA Schedule Internal readiness reviews:
Operational Readiness Review (ORR) scheduled for 30 October 2015
System Acceptance Review (SAR) scheduled for 6 January 2016
Actual near real-time data flow is dependent upon the new JPSS ground system upgrade (Jan 2016)
Existing users of S-NPP NDE system are already being integrated or are in the process of being scheduled for integration.
Existing users with further questions should contact:
Donna McNamara (Data Access Manager)
Chris Sisko (JPSS Data Operations Manager)
Matt Seybold (GOES-R Data Operations Manager)
New users with questions should contact NESDIS Satellite User Services:

13. PDA User Training
PDA user training will be made available in the Fall of 2015.
A PDA external User’s Guide will be available as well.
Training will be done locally in the Washington area, as well as remotely via Webinar.
Primary PDA Training POC:
Don Slater,
Linda – add Don Slater as POC.

14. Summary
The PDA will be the authorized enterprise distribution system for our near real-time users.
PDA will enable OSPO to:
deliver the large mission data (such as GOES-R, JPSS, etc.) to authorized users,
have greater management control and insight into distribution, and
enable NESDIS to more easily scale to meet future distribution demands while ensuring a secure distribution framework.
