- Abstract
- Terrestrial biosphere models (TBMs) have become integral tools for
extrapolating local observations and process-level understanding of
land-atmosphere carbon exchange to larger regions. Model-model and
model-observation intercomparisons are critical to understand the
uncertainties within model outputs, to improve model skill, and to improve
our understanding of land-atmosphere carbon exchange. The DataONE
Exploration, Visualization, and Analysis (EVA) working group is evaluating
TBMs using scientific workflows in UV-CDAT/VisTrails. This
workflow-based approach promotes collaboration and improved tracking
of evaluation provenance. But challenges still remain. The multi-scale and
multi-discipline nature of TBMs makes it necessary to include diverse and
distributed data resources in model evaluation. These include, among
others, remote sensing data from NASA, flux tower observations from
various organizations including DOE, and inventory data from US Forest
Service. A key challenge is to make heterogeneous data from different
organizations and disciplines discoverable and readily integrated for use in
scientific workflows. This presentation introduces the brokering approach
taken by the DataONE EVA to fill the gap between TBMs' evaluation
scientific workflows and cross-organization and cross-discipline data
resources. The DataONE EVA started the development of an Integrated
Model Intercomparison Framework (IMIF) that leverages standards-based
discovery and access brokers to dynamically discover, access, and
transform (e.g. subset and resampling) diverse data products from
DataONE, Earth System Grid (ESG), and other data repositories into a
format that can be readily used by scientific workflows in
UV-CDAT/VisTrails. The discovery and access brokers serve as an
independent middleware that bridge existing data repositories and TBMs
evaluation scientific workflows but introduce little overhead to either
component. In the initial work, an OpenSearch-based discovery broker is
leveraged to provide a consistent mechanism for data discovery.
Standards-based data services, including Open Geospatial Consortium
(OGC) Web Coverage Service (WCS) and THREDDS are leveraged to provide
on-demand data access and transformations through the data access
broker. To ease the adoption of broker services, a package of broker client
VisTrails modules have been developed to be easily plugged into scientific
workflows. The initial IMIF has been successfully tested in selected model
evaluation scenarios involved in the NASA-funded Multi-scale Synthesis
and Terrestrial Model Intercomparison Project (MsTMIP). (literal)
