Satellite microwave measurements complementary to fire weather improve the assessment of fires among different biomes in Southeast Asia.

Microwaves have the advantage of penetrating vegetation and exhibit sensitivity to properties such as vegetation water content (VWC); yet, their potential utility in the fire domain is infrequently investigated. This study elucidates the different impacts of the microwave VWC index EDVI on fire radiative energy (FRE) across various biome types and the significant predictive power for high-severity fires (defined based on FRE) in mainland Southeast Asia. While EDVI exhibits lower predictive power for high severe fires compared to the commonly used fire weather indices (e.

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

Fire emission is a major source of atmospheric nitrogen oxides (NO = NO + NO), accounting for a large part of global NO emission, which profoundly changes atmosphere physicochemical property and impacts human society. An effective evaluation of these impacts relies on accurate NO fire emission estimation. In this article, we developed a full top-down NO fire emission dataset for northeastern Asia based on the satellite-derived emission coefficient (EC) and fire radiative power (FRP) density.

Investigating the impacts of satellite fire observation accuracy on the top-down nitrogen oxides emission estimation in northeastern Asia.

NO fire emissions greatly affect atmosphere and human society. The top-down NO fire emission estimation is highly influenced by satellite fire observation performance (e.g.
