  journal={Geophysical Research Letters},
Assimilated inversion on a daily basis using OMI tropospheric NO2 columns is developed and applied in a regional chemical transport model (REAM) to constrain fossil fuel (FF) NOx emissions over east Asia in 2007. The iterative nature of the assimilated inversion improves upon the widely used monthly‐mean inversion by accounting for the chemical feedbacks of changed NOx emissions and reducing the dependence of the a priori emissions. The assimilated a posteriori emissions from FF combustion over… 

Anthropogenic emissions of NOx over China: Reconciling the difference of inverse modeling results using GOME‐2 and OMI measurements

Inverse modeling using satellite observations of nitrogen dioxide (NO2) columns has been extensively used to estimate nitrogen oxides (NOx) emissions in China. Recently, the Global Ozone Monitoring

Global NO x emission estimates derived from an assimilation of OMI tropospheric NO 2 columns

Abstract. A data assimilation system has been developed to estimate global nitrogen oxides (NO x ) emissions using OMI tropospheric NO 2 columns (DOMINO product) and a global chemical transport model

Satellite constraints of nitrogen oxide (NOx) emissions from India based on OMI observations and WRF‐Chem simulations

In this work, we map and develop for the first time an independent satellite constrained NOx emission inventory for India for 2005 using an inverse technique and iterative procedure. We used OMI

Worldwide biogenic soil NO x emissions inferred from OMI NO 2 observations

Abstract. Biogenic NOx emissions from soils are a large natural source with substantial uncertainties in global bottom-up estimates (ranging from 4 to 15 Tg N yr−1). We reduce this range in emission

Constraints on surface NOx emissions by assimilating satellite observations of multiple species

Surface NOx emissions are estimated by a combined assimilation of satellite observations of NO2, CO, O3, and HNO3 with a global chemical transport model. The assimilation of measurements for species

An Estimation of Top-Down NOx Emissions from OMI Sensor Over East Asia

This study focuses on the estimation of top-down NOx emissions over East Asia, integrating information on the levels of NO2 and NO, wind vector, and geolocation from Ozone Monitoring Instrument (OMI)

Application of satellite observations for timely updates to global anthropogenic NOx emission inventories

Anthropogenic emissions of nitrogen oxides (NOx) can change rapidly due to economic growth or control measures. Bottom‐up emissions estimated using source‐specific emission factors and activity
