  1. 3SDW test case at NPS/CIRA Mike Barna NPS-ARD 5/29/13 National Park Service U.S. Department of the Interior

  2. Intro • “first test case” CAMx run at NPS/CIRA a few weeks ago • July 2008 (with 10 day spin-up) • 36/12km domains (no 4 km domain) • ~3 days wall clock time on 3GHz ‘westmere’ cpu’s w/OMP and hyperthreading

  3. 36/12/4 km domains

  4. Process • Copied CAMx inputs to local storage • Built CAMx 5.41 w/OMP support • Created python run script

  5. Hiccups • Some configuration of CAM v.5.41 • Only one ‘initial condition’ file • A little tedious to convert csh to python…would be easier to have CAMx.in

  6. Results • Appears to be good match w/ ‘primary’ species (NO, NH3) • Some mismatch w/ozone • NPS O3 concentrations generally higher • Probably not due to initial conditions…persist to end of simulation

  7. Example O3 difference (July 31, 2008)

  8. Pilot study – NPS intermountain domain • Emission sectors: • O&G • EGU’s • Mobile • Area • Biogenic • Perform in-house at NPS/CIRA • Use CAMx DDM

  9. WestJump and NPS policy issues • WestJump is an ideal platform to ask questions about western US air quality: • “where are the problem areas?” • Base case run • “who is contributing to the problem?” • Source apportionment run • “how would the problem respond to changing emissions?” • DDM run • “what will this look like in the future?” • Future base case run

  10. Total N deposition

  11. PSAT tracers • Sulfur (2 Tracers) • o SO2i Primary SO2 emissions • o PS4i Particulate sulfate ion from primary emissions plus secondarily formed sulfate • Nitrogen (7 Tracers) • o RGNiReactive gaseous nitrogen including primary NOx (NO + NO2) emissions plus nitrate radical (NO3), nitrous acid (HONO) and dinitrogenpentoxide (N2O5). • o TPNiGaseousperoxylacetylnitrate (PAN) plus peroxynitricacid (PNA) • o NTRiOrganic nitrates (RNO3) • o HN3i Gaseous nitric acid (HNO3) • o PN3i Particulate nitrate ion from primary emissions plus secondarily formed nitrate • o NH3i Gaseous ammonia (NH3) • o PN4i Particulate ammonium (NH4)

  12. Wish list • Complete set of inputs • CAMx.in • Initial conditions • 4km met & emissions • More details regarding CAMx build • Pre-merged SMOKE files • Ancillary tools(?) • Collected obs (CASTNet, NADP, IMPROVE, etc) • UAM to netCDF conversion
