Hourly emission inventories for air toxic emissions for eastern Australian electricity generators derived from energy distribution data

Abstract

Emission inventories are a fundamental input for atmospheric chemical transport models in order to accurately simulate air pollution and its impacts. In Australia, emission inventories are currently not available for electricity generators at high temporal and spatial resolutions. In this study, a new high spatial and temporal resolution inventory for Australian power plant emissions has been developed. The emissions from coal- and gas-fired power plants have been estimated using 5-min electricity generation time-series data and emission factors. The emissions are estimated from 2010 to 2019 for sulfur dioxide (SO 2), nitrogen oxide (NO 2), particulate matter (PM) and mercury (Hg). We estima..
