New Terrestrial Carbon Sequestration Data Sets listed  
http://cdiac.ess-dive.lbl.gov/programs/CSEQ/cseqprojectdata.html
Dr.  Wilfred M. Post. 2005.



Two new data sets have been posted to the Terrestrial Carbon Sequestration Data Sets web page. One focuses on soil C loss following cultivation and the other with soil C accumulation following the establishment of forest or grassland on previously cultivated land.

AmeriFlux Database Continues to Grow

  The Editor. 2006.

CDIAC serves as the permanent data archive and focal point for the dissemination of long-term CO2, radiation, and water vapor flux measurements made at sites comprising the AmeriFlux network. AmeriFlux objectives include: 1) establish an infrastructure for guiding, collecting, synthesizing, and disseminating long-term measurements of CO2, water, and energy exchange from a variety of ecosystems; 2) collect critical new information to help define the current global CO2 budget; 3) enable improved predictions of future concentrations of atmospheric CO2; and 4) enhance understanding of carbon fluxes, Net Ecosystem Production (NEP), and carbon sequestration in the terrestrial biosphere. The AmeriFlux data collection now contains over 5 million data records for 60 measurement parameters from ~80 AmeriFlux sites. Data span the period 1991-2006.

Web-Accessible Visualization and Extraction System (WAVES) for Oceanographic Data   
http://cdiac3.ornl.gov/waves
Misha Krassovski and   Alex Kozyr. 2006.

WAVES, a web-based, database driven tool for oceanographic data (discrete measurements only at this time) extraction, is now available through CDIAC web page for use (http://cdiac3.ornl.gov/waves/). It lets users choose what kind of data they want to get and format. The interface has only one front page and all on-screen results are shown in a new window. The main page is divided in sections that help to navigate and keep different types of parameters grouped. In Query Parameters section users can set up searches for criteria and limitations. Single parameters, for example temperature from/to: 25oC, can be used as well as a range of parameters, e.g. temperature from: 20oC to: 25oC. The data location coordinates can be entered manually or by dragging a box on the map (icon with "i"). Map is tightened to Geographical Region, Section, and Cruise ID drop-down-menus and all changes are reflected on the map.

The output parameters section has list of all variables that can be extracted from the database. By clicking a checkbox next to the variable name, users may choose parameters that they need or chose all parameters clicking on "Check All" box. The format in which requested information will be presented is set up in the Output Form section. Users have options to get it as an on-screen table, as a downloadable file (CSV, TSV, NetCDF formats), or as an on-screen property-property plots.

The interactive map is designed to provide the metadata information which displayed in the clickable Metadata section by using an Information mode (icon with "i"). Users can receive metadata information by clicking on a cruise line, or by dragging a box in the research area of the map. The access to metadata provided through the same interface uses the background connection to metadata search engine Mercury. The map has also a Navigation mode (icon with palm). In Navigation mode, users can move map around (by dragging), zoom it in (icon with +), zoom it out (icon with -), and see the whole extend (icon with an arrow).

Architecture of WAVES is based on the following components: php engine, MySQL database, Subsys_JsHttpRequest library, Minnesota Map server, and ka-Map server. Php engine with DHTML and JavaScript is used as the main tool for interface creation, data extraction and forming results pages.

NARSTO's role in the Atmospheric Science Program (ASP)  
http://cdiac.ess-dive.lbl.gov/programs/NARSTO/narsto.html
  The Editor. 2005.

NARSTO is a public/private partnership, whose membership spans government, the utilities, industry, and academe throughout Mexico, the United States, and Canada. NARSTO's primary mission is to coordinate and enhance policy-relevant scientific research and assessment of tropospheric pollution behavior; its activities provide input for science-based decision-making and determination of workable, efficient, and effective strategies for local and regional air-pollution management. The Atmospheric Science Program (ASP) supports NARSTO by providing funding for the NARSTO Management Coordinator and by the ASP Program Director serving on the NARSTO Executive Steering Committee.

Search NARSTO holdings using the NARSTO Data and Information Sharing Tool (DIST)   
http://mercury.ornl.gov/narsto/
  The Editor. 2005.

Data from NARSTO projects are formatted in the NARSTO Data Exchange Standard (a spreadsheet-compatible layout, which uses a standardized terminology) and are sent to the NARSTO Quality Systems Science Center (QSSC). The QSSC does some format checking, interacts with the data providers as needed, develops additional documentation, and sends the data to the NARSTO Permanent Data Archive. You may use the NARSTO DIST to find NARSTO and related data sets; review the returned metadata; and link to and download selected data sets and documentation.

Search CDIAC holdings using with the CDIAC Mercury search tool  
http://mercury.ornl.gov/cdiac/
  The Editor. 2005.

Mercury is the Web-based system used by CDIAC to search the metadata, data, documentation, and to retrieve associated data. Recent new features to the CDIAC Mercury instance include a tabbed interface, the ability to address data granularity, and refinements to the CDIAC OME.

ORNL Climate Research   
http://climate.ornl.gov/
  The Editor. 2005.

The Coupled Carbon Cycle Climate Model Intercomparison Project (C4MIP), a joint project between IGBP-GAIM and WCRP-WGCM, is designed to compare and analyze the feedbacks between the carbon cycle and climate in the presence of external climate forcing. Such feedbacks are likely to be mediated on the one hand by altered forcing of the ocean and terrestrial carbon cycles and on the other by the impact of altered CO2 concentrations in the atmosphere resulting from this forcing. The basic approach is to include models of the terrestrial and ocean carbon cycles in existing OAGCMs and run the augmented model with and without these feedbacks active.
