Fire emissions only available for WRAP states.
Biogenic emissions available for all 50 states. Biogenic
emissions are processed for model input and are represented by 36km
grid cells, as opposed to county lines. Data by state includes some
overlap because grid cells cross state lines.Fire emissions summed
over all WRAP states. Seasonally dependent, emissions dominated by
wild fires.Comparison of biogenic VOC emissions for CA, AZ, CO, and
ND. Strong seasonal dependence, huge variation of magnitude across
WRAP region.Map of data within modeling domain for area source
emissions. Additional maps for other source categories (Area, Fire,
On and off-road mobile, road dust and biogenic emissions) are
available
at:http://www.wrapair.org/forums/aoh/ars1/emissions_maps.htmAnother
representation of area source emissions included in modeling. Same
data as previous slide. This map style indicates a better
representation of magnitude while the other is a better
representation of speciation. Preferences?WRAP SO2 emissions for
WRAP states separated by category. Summaries for other pollutants
available at:
