A new aerosol retrieval algorithm using multiangular total and polarized measurements is presented. The algorithm retrieves aerosol optical depth (AOD), fine-mode fraction (FMF) for studying the impact of aerosol on climate change. The retrieval algorithm is based on a lookup table (LUT) method, which assumes that one fine and one coarse lognormal aerosol modes can be combined with proper weigh...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Agricultural biomass burning (ABB) in Central and East China occurs every year from occurred mainly in An-hui, Henan, Jiangsu and Shandong provinces. A comprehensive set of aerosol optical 5 depth (AOD) data, produced...

Aerosol optical depth (AOD) is one of the basic characteristics atmospheric aerosol. A global ground-based network sun and sky photometers, Robotic Network (AERONET) provides AOD data with low uncertainty. However, AERONET observations are sparse in space time. To improve density, we merged a GEOS-Chem chemical transport model prediction using an optimal interpolation (OI) method. According to ...

Abstract. The Earth Explorer mission Clouds, Aerosols and Radiation (EarthCARE) will not only provide profile information on aerosols but also deliver a horizontal context to it through measurements by its Multi-Spectral Imager (MSI). columnar aerosol product relying these passive signals is called M-AOT (MSI-Aerosol Optical Thickness). Its main parameters are optical thickness (AOT) at 670 nm ...

Quantitative measurements of aerosol absorptive properties, e.g. the absorbing optical depth (AAOD) and single scattering albedo (SSA), are important to reduce uncertainties climate radiative forcing assessments. Currently, global retrievals AAOD SSA mainly provided by ground-based Aerosol RObotic NETwork (AERONET), whereas it is still challenging retrieve them from space. However, we found AER...

Abstract. The aerosol fine-mode fraction (FMF) is an important optical parameter of aerosols, and the FMF difficult to accurately retrieve by traditional satellite remote sensing methods. In this study, retrieval was carried out based on multiangle polarization data Polarization Anisotropy Reflectances for Atmospheric Science coupled with Observations from Lidar (PARASOL), which overcame shortc...

[1] We use an ensemble of satellite (MODIS), aircraft, and ground‐based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new retrieval of aerosol optical depths (AODs) and inferred surface aerosol concentrations (PM2.5) from the MODIS satellite instrument, and (3)...

The ground-based Atmospheric Radiation Measurement Program (ARM) and NASA Aerosol Robotic Network (AERONET) routinely monitor clouds using zenith radiances at visible and near-infrared wavelengths. Using the transmittance calculated from such measurements, we have developed a new retrieval method for cloud effective droplet size and conducted extensive tests for non-precipitating liquid water c...

The aerosol distribution in Europe was simulated with the Community Multiscale Air Quality (CMAQ) model system for the years 2000 and 2001. The results were compared with daily averages of PM10 measurements taken in the framework of EMEP and with aerosol optical depth (AOD) values measured within Aeronet. The modelled total 5 aerosol mass is typically about 30–60% lower than the corresponding m...
