Panel 4: What R&D Is Needed To Meet Urban Needs For Meteorological Information David Williams US Environmental Protection Agency
Context • R&D for in the area of urban meteorological information supports a wide range of requirements from: • Homeland security • Emergency response • City and regional planning • Global change research community
common and general set of building and landcover info for all cities nationwide Accurate met. Info (data/models) at meso urban building sale Data to confirm advanced modeling tool results (accuracy assessment) Question 1: what is needed
Question 2: R&D Activities of greatest potential • Observational data from collaborative field studies • Oklahoma City, Urban 2000 • Improved parameterization in mesoscale models (e.g. urban canopy parameters) and building-scale computational fluid dynamics (CFD) models • Fluxnet network, Landscan USA
Question 3: R&D areas that require attention • More collaborative work (e.g. Urban2000) • More urban data covering a wide variety of urban systems (east to west coverage) • Confirmatory data to validate simulation models (accuracy assessment) • Development of a National Database of Urban Parameters and landcover
Question 3: continued • Finish Landscan USA as soon as possible • Develop this dataset into a model to determine near-realtime population dynamics • Incorporate traffic flow to estimate area population densities in discrete timesteps
Question 4: R&D products ready for transfer • Advanced urban canopy models • CFD model results for certain areas (NYC, DC) • Geospatial data layers contained in the Homeland Security Infrastructure Program (HSIP), formerly NIMA/USGS 133 Urban Areas in the Nunn-Lugar-Dominici Act
Question 5: How well are current collaborations working • Field campaigns well organized • Fluid modeling progressing well • Organizations such as the Earth Science Information Partnership (ESIP) provides a good framework for urban meteorological information collaboration
Question 5: (cont) Where more is needed • No efforts to develop a National Database of Urban Met. Info. • Need greater access to data • Need to drive building-scale models with better meso-urban scale wind fields • Better collaboration between civil agencies and DoD (NGA, NORTHCOM)
Question 6: are current R&D transfer processes effective • Better tech transfer between civil and DoD to support urban applications would be beneficial • A workgroup should be formed to find ways to enable this • Testbeds – none planned • OK City and Houston studies provide framework for constructing a testbed
Conclusion • Although this work was reviewed by EPA and approved for publication, it may not necessarily reflect official Agency policy • Contact: David Williams williams.davidj@epa.gov (919) 541-2573
