Ozone (O3) pollution threatens global public health and damages ecosystem productivity. Droughts modulate surface O3 through meteorological processes vegetation feedbacks. Unraveling these influences is difficult with traditional chemical transport models. Here, using an atmospheric chemistry–vegetation coupled model in combination a suite of existing measurements, we investigate the drought impacts on explore main driving processes. Relative to mean state, accelerated photochemical rates...

Abstract Diffuse radiation can increase the light use efficiency for plant photosynthesis. However, lack of observations limits explorations diffuse fertilization effects on global scale. Here, we bias‐correct hourly fraction ( K d ) from a climate reanalysis using an artificial neural network (ANN) model in combination with site‐level observations. Evaluations at independent sites show that updated average increases correlations by 9.7% and reduces root‐mean‐square errors (RMSEs) 45.5%...
Abstract. Fire emissions influence radiation, climate, and ecosystems through aerosol radiative effects. These can drive rapid atmospheric land surface adjustments which feed back to affect fire emissions. However, the magnitude of such feedback remains unclear on global scale. Here, we quantify impacts aerosols forcing fast response direct, indirect, albedo effects based two-way simulations using a well-established chemistry–climate–vegetation model. Globally, cause reduction 0.565 ± 0.166...
Abstract. Aerosols can enhance ecosystem productivity by increasing diffuse radiation. Such fertilization effects (DFEs) vary among different aerosol compositions and sky conditions. Here, we apply a suite of chemical, radiation, vegetation models in combination with ground- satellite-based measurements to assess the impacts natural anthropogenic species on gross primary (GPP) through DFE from 2001–2014. Globally, aerosols GPP 8.9 Pg C yr−1 under clear-sky conditions but only 0.95 all-sky...
Biogenic isoprene is an important precursor of tropospheric ozone (O3). Here, a coupled chemistry–vegetation model was used to quantify the contributions emissions surface O3 pollution on global scale during 2000–2019. The biogenic showed high values in mid–low latitudes and seasonal peaks summer hemispheres. They promote concentrations by 1.75 ppbv annually with regional hotspots 4.39 (8.8%) China 5.36 (11.1%) U.S. boreal summer. In past two decades, increased 1.32 TgC yr−1 (0.67% yr−1)...
Abstract. A major limitation in modeling global ozone (O3) vegetation damage has long been the reliance on empirical O3 sensitivity parameters derived from a limited number of species and applied at level plant functional types (PFTs), which ignore large interspecific variations within same PFT. Here, we present advance large-scale assessments injury by linking trait leaf mass per area (LMA) broad perspective. Application new approach LMA map dynamic model reasonably represents observed...
Abstract Climate exerts both short-term and long-term impacts on the ecosystem carbon assimilation. However, main climatic drivers for variability of gross primary productivity (GPP) remain unclear across various timescales vegetation types. Here, we combine state-of-the-art machine learning algorithms with a well-established explanatory method to explore factors GPP at global FLUXNET sites four six plant functional Results show that diffuse shortwave radiation (SWdif) dominates sub-daily...

Such processes feed back inhibit dry deposition indirectly enhance O3. Here, we apply a fully coupled chemistry–vegetation model estimate the indirect contributions global fires through O3–vegetation feedback during 2005–2012. emissions directly increase annual mean by 1.2 ppbv (5.0 %) with maximum 5.9 (24.4 averaged over central Africa...
Abstract Isoprene dominates global biogenic volatile organic compounds and has significant impacts on atmospheric chemistry. Global simulations of isoprene emissions show large uncertainties in both the trend interannual variability. Here, we explored simulated during 1982–2015 using Yale Interactive terrestrial Biosphere model, which is implemented with two emission schemes (PS_BVOC Model Emissions Gases Aerosols from Nature [MEGAN]) driven by long‐term reanalysis meteorology (WFDEI...
When utilizing a finite volume method to predict outburst flood evolution in real geometry, the processing of wet-dry front and dry cells is an important step. In this paper, we propose new approach process cells, including four steps: (1) estimating intercell properties; (2) modifying interface elevation; (3) calculating cell elevations by averaging elevations; (4) changing value first term slope limiter based on geometry cells. The Harten, Lax, van Leer with contact wave restored (HLLC)...
Ozone pollution is harmful to human health and ecosystem, which occurs in ecosystems has occurred frequently China recent years, especially during the warm seasons. Meteorological conditions are among important factors affecting occurrence of ozone pollution. In this study, a classification method for meteorological levels based on back propagation (BP) neural network was proposed reflect impact divided into three according surface hourly (O3) concentrations thus groups conditions. The input...
Hourly scale hydrological modeling holds pivotal significance for flood-related research, as watershed floods often occur within a few hours of intense rainfall. Although the SWAT model’s hourly simulation has found application in watersheds, relatively short usage history and limited scope inhibit comprehensive grasp its potential.
