Actually the sweet smell is of the bacteria, Actinomycetes. These are type of filamentous bacteria that grow in soil when the conditions are damp or warm is what you snort.
When the soil dries, the bacteria produces spores, the wetness and the force of rain kick the spores in the air where the moisture that is after rain acts as aerosol.
The bacteria is extremely common and found all over the world, which explains the universal existence of sweet smell.
So, the aroma is nothing but an interplay of bacteria and the dampness that tickle your nasal cavity.
