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