We present results from and evaluate the performance of a 12-month, 12 km horizontal resolution year 2005 air pollution simulation for the contiguous United States using the WRF-Chem (Weather Research...
North American isoprene influence on intercontinental ozone pollution
North American isoprene intercontinental ozone pollution
font style='font-size:12px;'>
2011/2/25
Changing land-use and climate may alter emissions of biogenic isoprene, a key ozone (O3) precursor. Isoprene is also a precursor to peroxy acetyl nitrate (PAN) and thus affects partitioning among oxid...
