| Zusammenfassung |
| In pursuit of understanding environmental change and impact, scientists and decision makers
are challenged by the overwhelming plethora and volumes of data associated with climate
variability studies. In response to this challenge, NOAA is developing the National
Climate Model Portal (NCMP) to optimize operational access to the next generation,
high-resolution weather, reanalysis, and climate models. To reach goals set by this
diverse community of users, NCMP is advancing both a research component to better
understand the needs of the research community. Under a the new NOAA Cooperative
Institute for Climate and Satellites (CICS) in Asheville, North Carolina NCMP will
advance research collaborations to fulfill a National Academy of Science, Board of
Atmospheric Sciences and Climate (BASC) recommendation to advance multi-model
ensemble diagnostics. Further, NCMP will provide model diagnostic tools and a
software repository to advance statistical and dynamic downscaling and other user
needs at the Regional level and below. NCMP will advance the interoperable and
distributed data access philosophy currently employed in the NOAA Operational Model
Archive and Distribution System (NOMADS) [Rutledge et al., 2006] such as the
Open Geospatial Consortium (OGC) standards, the “Climate and Forecast” (CF)
metadata vocabulary, including NetCDF-CF; and the OPeNDAP transport and access
standard.
NCMP will be an initial access point to NOAA’s suite of model and reanalysis data sets
under the emerging NOAA Climate Service Portal (NCSP). Also- a close collaboration with
the developing National Climate Prediction and Projection Center prototype (NPCC) at
NOAA’s Earth System Research Laboratory (ESRL), NCMP will support access
to very large data to facilitate downscaling for regional and local users. Finally,
NCMP will support inter-comparison of model simulations and observations and
develop diagnostics tools that will be made available for use for the Intergovernmental
Panel on Climate Change (IPCC) Climate Model Intercomparison Project, phase
5 (CMIP-5) Fifth Assessment Report (AR5). NCMP is also working to provide
downscaling and data access support under a close collaboration with the next U.S Climate
Assessment.
To reach our varied community of users, NCMP will be designed to convey key aspects of
complex scientific data in a manner accessible and understandable to both scientists, and
non-specialists alike. The NCMP will be designed with three main user groups in mind: 1)
the lay person looking for information on how climate will affect their lives in the short-term
(seasonal), or long-term (decadal); 2) the sectorial business communities, including energy,
water, agriculture, transportation user groups and other regional and local domain specific
State and Local users of model data; and 3) the modeling and observational scientific
communities.
The NCMP design philosophy will leverage across existing partnerships, such as the
Department of Energy’s Earth System Grid Federation (ESGF) led by the Lawrence
Livermore National Laboratory [Williams et al., 2009]. NCMP will include a Geographic
Information System (GIS) component including ESRI’s GeoPortal Toolkit; and efforts
underway with NOAA’s Unified Access Framework (UAF). NCMP will leverage existing
partners and capabilities such as the ESGF and the replicated Intergovenmental Panel on
Climate Change (IPCC) Climate Model Inter-comparison Project Phase 5 multi-model
archive housed at the Program for Climate Model Diagnosis and Intercomparison (PCMDI)
at LLNL.
The data sets to be directly available or accessible thru ESFG under NCMP
include the suite of NOAA’s next generation climate reanalysis products including 1)
the NCEP Climate Forecast System Reanalysis and Reforecast (CFS-RR); and 2)
ESRL’s Twentieth Century Reanalysis Project (20CR), reanalysis dating from 1850 to
the present. Under ESGF all or subsets of the entire CMIP5 data holdings will be
searchable and available for access. Finally, NOAA’s numerical weather prediction
model output and ensemble based models generated at the National Centers for
Environmental Prediction (NCEP) will also be made available as a service under
NCMP.
