There is a fine line between testing "natural cloud formations" above populated areas and spraying "chemical clouds" for the sake of science!

Ganges Valley Aerosol Experiment (GVAX)
The proposed field study is designed for use of (1) the AMF to measure relevant radiative, cloud, convection, and aerosol optical characteristics over mainland India during an extended period of 12 months and (2) the G-1 aircraft and surface sites to measure relevant aerosol chemical, physical, and optical characteristics in the Ganges valley during a period of 8-12 weeks. The aerosols in this region have complex sources, including burning of coal, biomass, and biofuels; automobile emissions; and dust. The extended AMF deployment will enable measurements under different regimes of the climate and aerosol abundance in the wet monsoon period with low aerosol loading; in the dry, hot summer with aerosols dispersed throughout the atmospheric column; and in the cool, dry winter with aerosols mostly confined to the boundary later and mid troposphere. Each regime, in addition, has its own distinct radiative and atmospheric dynamic drivers. The aircraft operational phase will assist in characterizing the aerosols at times when they have been observed to be at the highest concentrations. A number of agencies in India will collaborate with the proposed field study and provide support in terms of planning, aircraft measurements, and surface sites. The high concentration of aerosols in the upper Ganges valley, together with hypotheses involving several possible mechanisms with direct impacts to the hydrologic cycle of the region, gives us a unique opportunity to generate data sets that will be useful both in understanding the processes at work and providing answers regarding the effects of aerosols on climate in a region where the perturbation is the highest.
