## Overview and Goals for the CLASS Workshop

**John J. Bates, NOAA**
**Chief, Remote Sensing Applications Division**
**National Climatic Data Center**
**NESDIS**

## Outline

**Overview of NOAA’s Goals, Climate Program, and Stewardship Elements**
**NOAA’s Archive Requirements Council (ARC) mission and terms of reference**
**Issues and challenges for the Workshop**

## Slide 3

## Slide 4

## NOAA’s Stewardship Principles

- Careful monitoring of observing system performance for long-term applications
- Generation of authoritative long-term records through validation of the calibration process, reprocessing, product generation and the blending of *in situ* and satellite measurements
- Provide state of the environment information for decision makers and place the current state in its historical context
- Archive, access and reprocessing of fundamental measurements, products and metadata
- Data archaeology and improved use

## CLASS Archive Requirements Council Mission

**The mission of the CLASS Archive Requirements Council (ARC) is to ensure that science requirements and other user applications are clearly defined.  The ARC will serve as a clearinghouse for requirement planning in support of the CLASS science objectives.  Validated requirements will be presented to the Data Archive Board for review and approval.  The ARC will provide advice and assistance, in coordination with the CLASS Project Manager and CLASS technical teams, to ensure that the requirements are dynamic and flexible in light of the rapidly changing user expectations and technological advancements **

## A Climate Requirements Process

**Must be a continuous process led by the climate science community**
**For NOAA, this currently involves**
- The NOAA Climate Program Office (Koblinski)
- The NOAA Climate Monitoring Working Group (Abbott)
- The NOAA Climate and Global Change Working Group (Brown)
**Nationally, involves the Climate Change Science Program (but needs interagency sub-set) and National Academies (CDR study underway)**
**Internationally, involves Global Climate Observing System (GCOS), World Climate Research Program (WCRP), Committee on Earth Observing Satellites (CEOS), etc.**
**Requires resources at the climate science level**

## ARC Terms of Reference 

**To ensure that CLASS is responsive to the goals of the NOAA strategic plan**
**To provide for effective use of CLASS by ensuring that mechanisms are in place to engage the user community in decisions concerning what data and products are to be included in or excluded from the CLASS**
**To periodically review the contents of the CLASS system for disposition in conjunction with data center NARA guidelines**
**To provide requirements and prioritization for preserving and maintaining the basic storage of and access to critical large array-data and derived products and their documentation, including verifying their quality and compliance with federal standards**
**To establish requirements for the IT aspects for implementation of scientific data stewardship of CLASS data sets and products**
**To provide a long-term vision to incorporate other NOAA data holdings into a system of archive, access, and scientific data stewardship**

## ARC Membership

**Membership shall consist of one member each from NCDC, NODC, NGDC, OSDPD, and ORA**
**NCDC – John Bates, Chair**
**NODC – Ken Casey**
**NGDC – Ted Habermann**
**OSDPD – Mac McCreary**
**ORA – Mitch Goldberg **

- Information Exchange

## ARC principles

**Data levels and prioritization**
**Value of historical data**
**Preservation of direct observations and fundamental measurements**
**Need for comprehensive documentation and metadata**
**Value of ‘in house’ data analysis and research**
**Reprocessing and enabling others to reprocess**
**Generation of long-term environmental records**
**Full and open access to data and products**
**Periodic review of products**
**Final disposition**

## Issues and Challenges for the Workshop

**What is the current status of CLASS, what are the major challenges, and how do we prioritize?**
**What components should CLASS include (levels of metadata, quality control, etc.) and what is the vision for CLASS?**
**How will CLASS interact with scientific data stewardship?**
**How should and will CLASS interact with affiliated archive, access, and reprocessing efforts throughout NOAA, with other agencies, and with the international community?**
