TLDR
In this paper, the vertical distribution of aerosols over a continental, urban location, Bangalore in southern India, using a micro pulse lidar (MPL) operated for about two years (2004 and 2005), was examined.Abstract:
Knowledge of the vertical distribution of aerosols in the atmosphere is important in estimating its radiative forcing. While aircraft based measurements over two locations in India have provided valuable information, the temporal coverage of measurements was limited. In this paper, we examine the vertical distribution of aerosols over a continental, urban location, Bangalore in southern India, using a micro pulse lidar (MPL) operated for about two years (2004 and 2005), and infer the effects of the boundary layer dynamics. Early morning hours are characterized by a shallow aerosol layer, a few hundred meters thick. As day advances, the strong convective eddies are seen to transport the aerosols vertically up to more than 1500 m. Seasonal changes in the aerosol vertical structure, contribution of the boundary layer aerosols to the column optical depth as well as the frequency of occurrence of clouds within aerosol layer are examined.read more

TL;DR: The Indian Ocean Experiment (INDOEX) documented this Indo-Asian haze at scales ranging from individual particles to its contribution to the regional climate forcing as discussed by the authors, and integrated the multiplatform observations (satellites, aircraft, ships, surface stations, and balloons) with one-and four-dimensional models to derive the regional aerosol forcing resulting from the direct, the semidirect and the two indirect effects.

Large differences in tropical aerosol forcing at the top of the atmosphere and Earth's surface
TL;DR: An observational method is presented for quantifying aerosol forcing to within ±5 per cent at the Earth's surface and the top of the atmosphere over the tropical northern Indian Ocean to imply that tropical aerosols might slow down the hydrological cycle.
