The NOAA CPO Modeling, Analysis, Prediction, and Projections (MAPP) program hosted a webinar on the topic of NOAA's Climate Test Bed: Improving Predictions and Modeling Systems on May, 2015. The announcement is provided below; you are invited to remotely join the session.
Sarah Lu - Through NCEP-GSFC collaborations, NASA’s bulk aerosol scheme has been implemented into NOAA Environmental Modeling System (NEMS) to establish the first interactive global aerosol forecasting system at NCEP. The global aerosol modeling efforts not only allow aerosol impacts on weather forecasts and climate predictions to be considered, but also enable NCEP to provide quality aerosol products that address societal needs and stakeholder requirements, e.g., air quality, UV index, ocean productivity, visibility, and sea surface temperature retrievals. This presentation will present the current global aerosol modeling capabilities, discuss ongoing activities and future directions, and shared the lessons learned for a robust and timely research-to-operation transition.
Mike Ek - The North American Land Data Assimilation System (NLDAS) is a long-term, multi-institutional project initiated to provide improved land surface initial conditions for weather and climate models, and subsequently expanded to support multiple applications related to land surface hydrology. Begun as a research project in January 2000, it became quasi-operational in September 2008, and operational at NCEP in August 2014. The NLDAS development included Phase 1 to establish the NLDAS configuration, including collection of soil and vegetation data, selection of land-surface models (LSMs), generation of surface forcing data sets, and model runs for a 3-year period, with evaluation/validation of model output. Phase 2 involved 30-year (1979-2008) retrospective and near real-time runs (2009-present) of four improved LSMs and surface forcing to generate energy and water fluxes, and state variables from those LSMs. The anomalies and percentiles from the 30-year climatologies for evapotranspiration, soil moisture, runoff/streamflow, and snow water equivalent have been comprehensively evaluated against observations, and are used to support US operational drought monitoring and prediction tasks such as the U.S. Drought Monitor, NCEP Climate Prediction Center drought information, and activities of the National Integrated Drought Information System. More than 36 years of surface forcing and model output data have been distributed by the NCEP/EMC NLDAS website (www.emc.ncep.noaa.gov/mmb/nldas), the NASA Goddard Earth Sciences Data Information Services Center (GES DISC, daac.gsfc.nasa.gov), the UCAR/NCAR Climate Data Guide (climatedataguide.ucar.edu/climate-data), and the USGS Geo Portal (cida.usgs.gov/gdp). The operational implementation provides more reliable and timely access to NLDAS products. This presentation summarizes experiences of NLDAS, status and format of current NLDAS products, and the future plans for NLDAS.
Cecelia DeLuca - Using common standards for data, metadata, and modeling software interfaces is a key strategy for enabling knowledge and technical transfers between the research and operational communities. The NOAA Environmental Software Infrastructure and Interoperability (NESII) team at ESRL collaboratively manages standardization and community infrastructure projects that are critical to R2A partnerships. These multi-agency projects are run in an open, inclusive, distributed manner that encourages broad participation. They include the Earth System Modeling Framework (ESMF) and National Unified Operational Prediction Capability (NUOPC) Layer, which define a set of component interfaces for constructing coupled models; the Earth System Framework Description Language (ES-FDL), a new tool useful for describing and linking different modeling infrastructures; Earth System CoG, a web-based environment for connecting projects and sharing data internationally; Earth System Documentation (ES-DOC), an E.U.-led partnership that develops tools for metadata collection and dissemination; and Cupid, an ESMF training and development environment that will be deployed to support O2R outreach. The NESII team reaches across research and operational settings, providing value to both sides and a path for bridging these communities. We will discuss NESII infrastructure and its applications, including its role in bringing community models into the emerging NOAA Environmental Modeling System (NEMS).
