That's very nice stuff, but the Asian brown cloud is not the same as dust from Asia. The Asian brown cloud is a haze of organic pollutants and smoke (over India, cooking fires are a major contributor; over China, coal-fired electricity plants and coal-burning factories are the problem) that lies over the Indian Ocean, Indonesia, and parts of the South China Sea.
