ICAP Modeling and Analysis Components

Develop meteorological and emissions data for modeling trans-Pacific and trans-Atlantic pollutants transport

Apply global chemistry-transport models and develop an interface for Regional modeling nesting using CMAQ

Apply global chemistry-radiation-climate models to assess the linkage of air pollution to regional climate

Analyze and evaluate the model results using surface-based, aircraft and satellite observations

ICAP Emissions Overview: Trans-Pacific and Trans-Atlantic

October 2004

North America NEI 1999 v1 point, area, nonroad and mobile 1992 Offshore (Gulf of Mexico) point source data Used BRAVO Mexican 1999 inventory databases

available 1995 Canadian point, area, nonroad and mobile

source inventory (source Env. Canada) Includes point, area/nonroad and onroad sources Includes continuously emitted volcanos



N. America: SMOKE processing SMOKE-BEIS3 for most of N. America; GEIA

biogenic inventory used elsewhere (hourly variation)

Use SMOKE to speciate pollutants for the CB-IV with PM

Performed plume rise on all sources with stack height > 40m using SMOKE and MCIP data

Use SMOKE to temporal allocate using monthly, weekly and diurnal profiles



Asian Inventory Input Data Consisted 10 different anthropogenic components:

– Aviation

– Biomass burning

– Domestic biofuels

– Domestic fossil fuels

– Industry

– Other

– Point sources

– Power

– Shipping

– Transportation



Asian Inventory Input Data cont’

Data contains CB-IV with PM species Assign weekly and hourly profiles based on N. American

examples GEIA used for biogenic emissions for Asia and Pacific

including Hawaii and Alaska Includes steel and iron mills and other “large” pt sources Volcanoes supplied by Dr. Woo and additional continuous

emitting volcanoes from GEIA Used 16-layer MCIP data to vertically allocate point sources

and temporally allocate biogenic emissions Simple dust model using MCIP data used to generate crude

estimates of fine and coarse dust particles (also applied in N. America)







Future year scenarios

Two future year scenarios (A1B and B1) generated for year 2030 using projection factors obtained from Dr. Streets.

Gridded projection factors used to multiply 2001 ICAP Trans-Pacific emissions to generate CMAQ-ready emissions for both 2030 scenarios



Trans-Atlantic: Europe EI Consisted 8 different anthropogenic

components:– Aviation– Biomass burning– Domestic fuels– Industry– Other– Power– Shipping– Transportation

GEIA used for biogenic emissions for Europe/Asia

Continuous emitting volcanoes from GEIA
