Abstract

A high-resolution (1 km) daily fire-sourced MDA8 ozone dataset over the continental USA from 2003 to 2023. Fire-sourced MDA8 ozone is estimated as the product of all-source high-resolution MDA8 ozone (available at https://zenodo.org/records/17502917) and the fire-attributable fraction estimated from two GEOS-Chem simulations conducted with and without GFED4s fire emissions.
