MACE Analysis of MFRSR Multi-spectral Atmospheric Column Extinction (MACE) analysis of multi-filter rotating shadowband radiometer (MFRSR) measurements yield detailed time series information on the variations of the column amounts of atmospheric NO2 and ozone and of aerosol optical depth, including the effective particle size and variance of the aerosol size distribution. Retrieval of such deta...

[1] Aerosol absorption of sunlight, in particular by black carbon soot and dark organic material produced from incomplete combustion of fossil fuel and from vegetation fires, is emerging as a key component of climate forcing. However, global characterization of black carbon emissions, distribution and absorption of sunlight cannot be determined within a factor of 5. Here we propose that the oce...

Because industrial emissions of anthropogenic aerosols over East Asia have greatly increased in recent decades, the interactions between atmospheric aerosols and the East Asian summer monsoon (EASM) have attracted enormous attention. To further understand the aerosol-EASM interaction, we investigate the impacts of anthropogenic aerosols on the EASM during the multidecadal strong (1950–1977) and...

Recent laboratory studies have demonstrated that isoprene oxidation products can partition to atmospheric aerosols by reacting with condensed phase sulfuric acid, forming low-volatility organosulfate compounds. We have identified organosulfate compounds in free tropospheric aerosols by single particle mass spectrometry during several airborne field campaigns. One of these organosulfates is iden...

Atmospheric aerosol particles impact the Earth’s energy budget through reflection and absorption of solar radiation (the aerosol direct effect) and modification of cloud properties (the aerosol indirect effect). The scattering of incoming solar radiation back to space results in a net decrease in heating at the Earth’s surface. The absorption of solar energy alters the atmospheric heating rate,...

This manuscript describes vertical profiles of aerosol number density over Arctic during spring and summer and presents authentic and original scientific material that has relevant implications for atmospheric science (aerosol, clouds, CCN, and others). This study is based on very important aerosol data over Ny-Ålesund, Svalbard, although the tethered-balloon-borne aerosol measurements are rest...

Aerosol properties are retrieved from ATSR-2 data (ERS2 satellite) by utilizing the dual view for application over land and the single view for application over water. These two algorithms have been merged into a fast and efficient algorithm that allows for near real-time processing and which is suitable for operational use. It includes corrections for surface and atmospheric effects including ...

Gordon Appl. Opt. 42, 542 2003 argues that use of external rather than internal mixing when aerosol optical properties are computed will not seriously affect atmospheric correction of ocean color imagery, in spite of the fact that top of the atmosphere reflectances computed with the two approaches differ significantly as shown by Yan et al. Appl. Opt. 41, 412 2002 . We apply an algorithm for si...

Retrieval of the surface reflectance is important in the remotely sensed data analysis to obtain the atmospheric reflectance or atmospheric correction. The relationship between visible and mid infrared reflectance over land was investigated and developed in this study. The surface reflectances of the two visible bands were measured using a handheld spectroradiometer collected around Penang Isla...

The seasonal and diurnal behavior of atmospheric submicron aerosol was studied in the northern Indian city of Kanpur in the Indo Gangetic Plain during July 2006–May 2007. The size distribution and mass concentration of the aerosol in the range of 15-700 nm was measured using a scanning mobility particle sizer (SMPS). Simultaneously, black carbon (BC) measurement was made using an aethalometer. ...
