Estimating wildfire-generated ozone over North America using ozonesonde profiles and a differential back trajectory technique
An objective method, employing HYSPLIT back-trajectories and Moderate Resolution Imaging Spectroradiometer (MODIS) fire observations, is developed to estimate ozone enhancement in air transported from regions of active forest fires at 18 ozone sounding sites located across North America. The Differe...
