A myth debunked: H 2 CO 3 may form in the atmosphere from mineral dust in the presence of acid and remain stable there for long periods even in the presence of rather high relative humidity. The image illustrates the mechanism of its formation on the background image of Saharan dust transported to the west of Spain and North Africa.
