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
hyperthreadingSlide3
36/12/4 km domainsSlide4
Process
Copied
CAMx
inputs to local storage
Built
CAMx
5.41 w/OMP support
Created python run scriptSlide5
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.inSlide6
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 simulationSlide7
Example O3 difference (July 31, 2008)Slide8
Pilot study – NPS intermountain domain

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 runSlide10
