Reduction of Global Sulfate Aerosol Concentration and Corresponding Radiative Effects From Recent Chinese SO2 ${\text{SO}}_{2}$ Emission Reduction

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Anthropogenic emissions over China have recently declined due to environmental actions. This work estimates the sensitivity of sulfate aerosol (SO4 ${\text{SO}}_{4}$) concentration to the amount of SO2 ${\text{SO}}_{2}$ emissions reduction over China from 2010 to 2020 using an Earth system model with two different aerosol representations.

Subtyping for Hierarchical, Reconfigurable Petri Nets

open access: yes, 2018
Hierarchical Petri nets allow a more abstract view and reconfigurable Petri nets model dynamic structural adaptation. In this contribution we present the combination of reconfigurable Petri nets and hierarchical Petri nets yielding hierarchical structure

Growth in Production and Environmental Deposition of Trifluoroacetic Acid Due To Long‐Lived CFC Replacements and Anesthetics

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Trifluoroacetic acid (TFA) is a persistent pollutant with potential long‐term effects on the environment and on health. Recent studies using ice core records report large increases (up to tenfold) in Arctic TFA deposition since the 1970s, and trends suggest long‐lived chlorofluorocarbon (CFC) replacements may be a major source.
