Abstract: We have done extensive work in the past to test the reduction in air pollution and increase in precipitation by burning Indian Cow Ghee in a process called as Yajna. We are interested in knowing whether the humidity can be increased due to anthropogenic aerosols and in particular due to burning of aromatic compounds such as Indian Cow Ghee (clarified butter) that too in winter (December) in GA? We found that even in peak winter the Yajna process could increase the humidity by about 40%.
