The high-resolution biogenic emissions inventory from urban green spaces in China (OUC-BUGS)

Overview >

The high-resolution biogenic emissions inventory from urban green spaces in China (OUC-BUGS) was developed by Ocean University of China (Prof. Yang Gao). OUC-BUGS, including more than 150 volatile organic compounds (VOCs) such as isoprene, terpenes, was estimated by Model of Emissions of Gases and Aerosols from Nature (MEGAN). The emission calculations are based on two landcover datasets at spatial resolutions of 10-m and 500-m, as well as hourly simulated meteorological parameters., OUC-BUGS currently provides hourly gridded biogenic emissions from urban green spaces during 2015-2019 in China at 27 km spatial resolution. If you have any questions, please contact Prof. Yang Gao (
