Dataset of top-down nitrogen oxides fire emission estimation in northeastern Asia?

Fire emission is a major source of atmospheric nitrogen ox-ides (NOx = NO2 + NO), accounting for a large part of global NOx emission, which profoundly changes atmosphere physic-ochemical property and impacts human society. An effective evaluation of these impacts relies on accurate NOx fire emis-sion estimation. In this article, we developed a full top-down NOx fire emission dataset for northeastern Asia based on the satellite-derived emission coefficient (EC) and fire radiative power (FRP) density. In the dataset, daily NOx fire emissions during 2012-2019 were estimated at 1 degrees x1 degrees resolution across northeastern Asia, which can be used as fundamental input data in driving climate and weather models, and can be ap-plied to investigate the characteristic of fire emission, fire -climate interaction, air pollution and human health effect. As a full top-down emission dataset, it can also serve as a refer-ence for other existing emission inventories that are mostly based on bottom-up approaches.(c) 2022 The Author(s).
