Biomass burning emission estimation in the Modis era: State-of-the-art and future directions
Accurate estimates of biomass burning (BB) emissions are of great importance worldwide due to the impacts of these emissions on human health, ecosystems, air quality, and climate. Atmospheric modeling efforts to represent these impacts require BB emissions as a key input. This paper is presented by the Biomass Burning Uncertainty: Reactions, Emissions and Dynamics (BBURNED) activity of the International Global Atmospheric Chemistry project and la…
A top-down estimation of subnational CO 2 budget using a global high-resolution inverse model with data from regional surface networks
Top-down approaches, such as atmospheric inversions, are a promising tool for evaluating emission estimates based on activity-data. In particular, there is a need to examine carbon budgets at subnational scales (e.g. state/province), since this is where the climate mitigation policies occur. In this study, the subnational scale anthropogenic CO 2 emissions are estimated using a high-resolution global CO 2 inverse model. The approach is distinctiv…
Interannual variability on methane emissions in monsoon Asia derived from Gosat and surface observations
In Asia, much effort is put into reducing methane (CH 4 ) emissions due to the region’s contribution to the recent rapid global atmospheric CH 4 concentration growth. Accurate quantification of Asia’s CH 4 budgets is critical for conducting global stocktake and achieving the long-term temperature goal of the Paris Agreement. In this study, we present top-down estimates of CH 4 emissions from 2009 to 2018 deduced from atmospheric observations from…
Sensitivity of mesoscale modeling of smoke direct radiative effect to the emission inventory: A case study in northern sub-Saharan African region
An ensemble approach is used to examine the sensitivity of smoke loading and smoke direct radiative effect in the atmosphere to uncertainties in smoke emission estimates. Seven different fire emission inventories are applied independently to WRF-Chem model (v3.5) with the same model configuration (excluding dust and other emission sources) over the northern sub-Saharan African (NSSA) biomass-burning region. Results for November and February 2010 …
Bounding the role of black carbon in the climate system: A scientific assessment
Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment provides an evaluation of black‐carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; i…
