The GOES Eastern United States Fire Emissions Inventory

Charles H. Fite, Aditya Kumar, Holly K. Nowell, Katherine R. Travis et autres

Abstract Prescribed wildland and agricultural fires are common in the eastern United States (U.S.), but their small size and short durations have led polar‐orbiting satellite data sets to underestimate their emissions due to omission. The higher temporal resolution of the GOES‐16 Advanced …

AI-enhanced subseasonal forecasting of extreme temperature risks

Jia Xing, Siwei Li, Shuxin Zheng, Ge Song et autres

Sub-seasonal weather prediction remains a significant scientific challenge due to the chaotic nature of the atmosphere, with current numerical and AI-driven models exhibiting limited skill, particularly at the fine spatial scales for human exposure, agriculture, and infrastructure. Here, we introduce DeepMet, a …

Atmospheric processing and aerosol aging responsible for observed increase in absorptivity of long-range-transported smoke over the southeast Atlantic

Abdulamid A. Fakoya, Jens Redemann, Pablo Enrique Saide, Lan Gao et autres

Biomass burning aerosol (BBA) from agricultural fires in southern Africa contributes about one-third of the global carbonaceous aerosol load. These particles have strong radiative effects in the southeast Atlantic (SEA), which depend in part on the radiative contrast between the aerosol layer …
