Changing atmospheric aerosol properties caused by anthropogenic activities carries serious implications for climate change and human health. The launch of the Multi‐angle Imaging SpectroRadiometer (MISR) onboard Terra spacecraft more than a decade ago provides the first capability to monitor several physical properties of aerosols over land from space. We use ten years (Mar 2000–Feb 2010) of observations from MISR to quantify seasonal linear trends of aerosol optical depth (τ) segregated by… 

Decadal-scale trends in regional aerosol particle properties and their linkage to emission changes

Understanding long-term trends in aerosol loading and properties is essential for evaluating the health and climatic effects of these airborne particulates as well as the effectiveness of pollution

Variability of Atmospheric Aerosols Over India

Atmospheric aerosols play a significant role in climate change due to their ability to scatter and absorb the incoming and outgoing radiation (direct effect). In addition to this, aerosols can also

Multi-decadal aerosol variations from 1980 to 2009: a perspective from observations and a global model

Abstract. Aerosol variations and trends over different land and ocean regions from 1980 to 2009 are analyzed with the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model and observations

Buildup of aerosols over the Indian Region

Climate change has great significance globally in general and South Asia in particular. Here we have used data from a network of 35 aerosol observatories over the Indian region to generate the first

Towards understanding the variability of aerosol characteristics over the Indo-Gangetic Plain

Ground and satellite based measurements show significant loading of atmospheric aerosols over the highly populated Indo-Gangetic Plains with implications to both air quality and regional climate.

Atmospheric aerosol optical depth and its variability over an urban location in Eastern India

Eastern India is characterized by high aerosol loading of primarily anthropogenic origin due to both local emissions and long-range transport and hence outflow of air mass from the Indo-Gangetic

Variability and trends of aerosol properties over Kanpur, northern India using AERONET data (2001–10)

Natural and anthropogenic aerosols over northern India play an important role in influencing the regional radiation budget, causing climate implications to the overall hydrological cycle of South

Variability and Trends of Aerosol Properties over Kanpur, Northern India Using AERONET Data (2001–10) data files

Natural and anthropogenic aerosols over northern India play an important role in influencing the regional radiation budget, causing climate implications to the overall hydrological cycle of South



A climatology of aerosol optical and microphysical properties over the Indian subcontinent from 9 years (2000–2008) of Multiangle Imaging Spectroradiometer (MISR) data

Received 16 October 2009; revised 20 January 2010; accepted 25 January 2010; published 5 August 2010. [1] We present the first detailed analysis of a 9 year (2000–2008) seasonal climatology of size‐

Anthropogenic and natural contributions to regional trends in aerosol optical depth, 1980–2006

[1] Understanding the roles of human and natural sources in contributing to aerosol concentrations around the world is an important step toward developing efficient and effective mitigation measures

Analysis of Multi‐angle Imaging SpectroRadiometer (MISR) aerosol optical depths over greater India during winter 2001–2004

We present the first detailed spatial analysis of a four‐year, wintertime visible aerosol optical depth (AOD) climatology from the Multi‐angle Imaging SpectroRadiometer (MISR) over greater India.

A decadal regional and global trend analysis of the aerosol optical depth using a data-assimilation grade over-water MODIS and Level 2 MISR aerosol products

Abstract. Using the ten-year (2000–2009) Data-Assimilation (DA) quality Terra MODIS and MISR aerosol products, as well as 7 years of Aqua MODIS, we studied both regional and global aerosol trends

An ensemble of coupled ocean-atmosphere simulations from 1930 to 2000 suggest that absorbing aerosols in atmospheric brown clouds may have played a major role in the observed regional climate and hydrological cycle changes and have masked as much as 50% of the surface warming due to the global increase in greenhouse gases.

Trends in aerosol optical depth for cities in India

Examination of direct cumulus contamination on MISR‐retrieved aerosol optical depth and angstrom coefficient over ocean

The effect of direct cumulus contamination on the aerosol optical depth (AOD) and angstrom exponent (AE) from the Multi‐angle Imaging SpectroRadiometer (MISR) was examined using overlapped 15‐m

Clear Sky Visibility Has Decreased over Land Globally from 1973 to 2007

The aerosol contribution to “global dimming,” first reported in terms of strong decreases in measured incident solar radiation up to the mid-1980s, has monotonically increased over the period analyzed.

Observational evidence of solar dimming: Offsetting surface warming over India

Monthly mean surface reaching solar radiation (S) measurements under all sky conditions have been evaluated for 12 stations, which are widely distributed over the Indian region, for the period

MISR Global Aerosol Product Assessment by Comparison with AERONET

A statistical approach is used to assess the quality of the MISR Version 22 (V22) aerosol products. Aerosol Optical Depth (AOD) retrieval results are improved relative to the early post- launch
