“…There are several studies on aerosol optical properties seen from satellites and AERONET measurement stations (Ramachandran, 2007;Ramachandran and Cherian, 2008). In recent modeling studies, for instance seasonal cycle characterization and climate impact assessment has been made and satellite measurements of aerosol optical depth have been assimilated with chemical transport models Roeckner et al, 2006b;Adhikary et al, 2008).…”

“…Several studies have used aerosol optical depth (AOD, also referred to as aerosol optical thickness or AOT) observations along with CTM to obtain better air quality re-analyses. Some of these studies used the OI technique along with models such as STEM (Adhikary et al, 2008;Carmichael et al, 2009), CMAQ Park et al, 2014), MATCH (Collins et al, 2001), and GOCART (Yu et al, 2003). Other studies used variational approaches with models such as EU-RAD (Schroedter-Homscheidt et al, 2010;Nieradzik and Elbern, 2006) and LMDz-INCA (Generoso et al, 2007).…”

“…The OI method is described in detail in Adhikary et al (2008). Before assimilation, we put AIRNow in situ data and MODIS AOD data into their corresponding model grids.…”

“…The relative uncertainties of MODIS AOD and AIRNow PM 2.5 and O 3 were set to 0.2, 0.2, and 0.1, respectively. The cases of OI1, OI2, and OI3 were performed in a 7 × 7 grid box (Adhikary et al, 2008). OI4 was performed in an 11 × 11 grid.…”
