to the top Introduction

During 2003, the Climate Change Data and Detection (CCDD) program element established an Applied Research Center (ARC) for Data Set Development, in response to NOAA's growing emphasis on the transfer of research results to operational applications. The transition from research to operations for data set production recognizes that certain data sets have a broad base of regular users and enduring value (e.g., for national/international assessments) and, consequently, require regular and careful updating and improvement. The intent of the ARC is to provide an incubator for transitioning data sets from the OGP research stream to an operational entity, i.e., a facility where there is an institutional commitment to update and produce the data set indefinitely.

The ARC reflects the duality of the CCDD project portfolio - we have one group of projects (the ARC) that meets our continuing responsibility to provide basic, global, climate reference data sets, e.g., COADS, GHCN, GPCP and ocean data archeology, and we have a second group of projects that is composed of innovative, shorter term, focused projects that include significant research and analysis components in addition to producing/improving data sets. The purpose of the ARC is not to conduct fundamental research, but to ensure routine data set production with appropriate scientific oversight. Transitioning the production of reference climate data sets from research to operations does not mean routinely "turning the crank". Without involvement and oversight by interested scientists, the completeness and quality of a climate data set inevitably suffer. Each data set has a designated "champion" who is responsible for guaranteeing the scientific integrity of the data set.

As the ARC concept matures and assumes its place as a cornerstone of the CCDD program element, it is essential that the two groups of projects identified above are linked in ways that foster the transfer of the research into NOAA operations and data sets. This will require frequent two-way communication between the P.I.s on the research projects and the P.I.s within the relevant ARC activities.

The developer of the data set will be responsible for:

- developing operational software and documentation in accordance with national or international standards

- quantifying error characteristics

- ensuring that the data set is open and available

- updating the data set on a routine basis

The ARC for Data Set Development was established in conjunction with the National Climatic Data Center (NCDC). The program manager of CCDD and the Director of NCDC jointly manage the ARC. CCDD provides (block) funding for the ARC and NCDC is the focal point for coordination of proposal submission, reporting, individual project fund transfers, and project review.

Our objective is to produce high quality up-to-date data sets for use in answering the pressing climate and global change questions.

to the top PI Instructions

Principal Investigators should plan on submitting the following information for publication on the ARC web site (single file in .pdf format preferred):

- Brief Introduction/Overview of the dataset

- Basic Description of Dataset

(A) Variables
(B) Type of Observations
(C) Geographic Coverage
(D) Resolution (Spatial and Temporal)
(E) Duration
(F) Update Interval
(G) Access Mechanisms (e.g. WWW)
(H) Operational Applications (e.g. Assessments)

- Scientific stewardship activities required for continued production of the data set

This is where the PI should outline the current and future foci of the production effort, (i.e. what are the important, specific things that need to be done to produce a high quality data set).

In addition, PI's should include the full web address of any existing dataset website and also the full ftp web address of any ftp site that is delivering part and/or all of the dataset.

Finally, PI's are encourged to examine the template files listed on this web site (in .pdf format) to use as a guide in writing their own ARC dataset documentation file.
