    Carbon dioxide fluxes and the dominant role of vegetation in recently created and reference Gulf Coast marshes by A. Muench, T. Elsey‐Quirk, J. R. White, R. D. DeLaune

    Published 2024-12-01
    “…Wetland loss due to anthropogenic and natural causes reduces the carbon (C) storage capacity and potentially releases previously fixed C in biomass and soil to the water column and atmosphere through decomposition. Coastal wetland restoration has the potential to mitigate some of the C losses depending on the balance of C fluxes. …”

    Aerosol Opto-physical Properties: Temporal Variation, Aerosol Type Discrimination and Source Identification by Amol R. Kolhe, Gajanan Raghunath Aher, Pawan S. Soyam, Sachin D. Ralegankar, Sumita Kedia, Laxman M. Chaudhari, Vivek V. Antad, Sachin D. Ghude, Pramod D. Safai, Sanjay D. Chakane, Panuganti C. S. Devara

    Published 2022-08-01
    “…The AOD500 nm against AE440-870 nm contour density map analysis qualitatively characterizes different aerosol types prevalent in the atmospheric column. The weighted PSCF (WPSCF) analysis for AOD performed on a seasonal basis reveals the presence of possible contribution of long-range transported plumes of varied aerosols on different scales and types from a variety of emission sources from different regions.…”
