## PSS PDS Presentation

## What is PDS?

**The Planetary Data System’s job is to...**
**Provide help to NASA missions and other data providers to organize and document their digital planetary data**
**Collect complete, well-documented planetary data into archives that are peer-reviewed**
**Make the planetary data available and useful to the science community**
**Ensure the long-term preservation and usability of the data.**

## What is PDS?

**How PDS makes data available to the public**
**Data archives reside at the PDS Discipline Nodes where they are maintained by scientists who use the data and who can provide expert help.**
**Most PDS archives are available online for downloading and some can also be requested on CD or DVD.**
**PDS provides online search tools to help locate data of interest.**

***PDS Discipline Nodes***
***Atmospheres Node****, New Mexico State University in Las Cruces, New Mexico*
***Geosciences Node****, Washington University in St. Louis, Missouri*
***PPI**** ****(Planetary Plasma Interactions) Node****, UCLA, Los Angeles, California*
***Rings Node****, SETI Institute, Mountain View, California*
***Small Bodies Node****, University of Maryland, College Park, Maryland*
***Imaging Node****, U.S. Geologic Survey in Flagstaff, Arizona and Jet Propulsion *
*Laboratory in Pasadena, California*
***PDS Support Nodes***
***NAIF**** ****(Navigation and Ancillary Information Facility) Node****, Jet Propulsion Laboratory*
***Engineering Node****, Jet Propulsion Laboratory*

## Components of a PDS Archive

**Data products with PDS labels**
**Index of data products**
**Calibration data and reports, if any**
**Documentation**
**SIS documents**
**PDS catalog information**
**Other documentation**
**Software to read the data, if needed **
**Optional extra material**
**Quick-look or browse versions of data**
**Analysis software**

***Types of Data Products:***
***EDRs**** – Experiment Data Records (raw data)*
***RDRs**** – Reduced Data Records (derived data)*
***Standard Products**** – EDRs or RDRs that are generated in pipeline fashion *
***Special Products**** – RDRs of special interest generated as resources permit*

## Archiving Steps: Planning

**LRO Instrument Team Planning**
**Designate the team’s archiving point of contact.**
**Attend Data and Archive Working Group meetings.**

| LRO Archive  | PDS Discipline Node Contact |
| --- | --- |
| CRaTER | PPI Node, UCLARay Walker (rwalker@igpp.ucla.edu) |
| LAMP,LROC | Imaging Node, USGS/JPLLisa Gaddis (lgaddis@usgs.gov) Sue LaVoie (Susan.K.LaVoie@jpl.nasa.gov) |
| Diviner,LEND,LOLA, Mini-RF | Geosciences Node, Washington U.Ray Arvidson (arvidson@wunder.wustl.edu) |
| SPICE | NAIF Node, JPLChuck Acton (Charles.Acton@jpl.nasa.gov) |

**Write an *****Interface Control Document (ICD)***** to specify work to be done by the Team and by PDS.**

## Archiving Steps: Planning

**LRO Instrument Team Planning, continued...**
**Design data products and PDS labels.**
**Write *****Data Product SIS***** to describe data products in detail.**
**Write *****Archive Volume SIS***** to describe contents of the complete archive.**
**Submit sample data products, labels, and draft SISs to a peer review.**
**All of this is done with help from the team’s designated PDS Node, as needed.**

***Peer Review***
*A peer review is required for all PDS archives. *
*The review happens in the design phase while there is still time to make changes if needed.*
*The review committee is a small number of scientists who are interested in the data.*
*The PDS Discipline Node leads the review, which is conducted by email and teleconference or in person*
