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

36/12/4 km domains

Process

• Copied CAMx inputs to local storage

• Built CAMx 5.41 w/OMP support

• Created python run script

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

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

Example O3 difference (July 31, 2008)

Pilot study – NPS intermountain domain• Emission sectors:

• O&G• EGU’s• Mobile• Area• Biogenic

• Perform in-house at NPS/CIRA

• Use CAMx DDM

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

Total N deposition

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 RGNi Reactive gaseous nitrogen including primary NOx (NO + NO2) emissions plus nitrate radical (NO3), nitrous acid (HONO) and dinitrogen pentoxide (N2O5).

o TPNi Gaseous peroxyl acetyl nitrate (PAN) plus peroxy nitric acid (PNA) o NTRi Organic 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)

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
