Mitti ka Kushboo (The earthy smell after Rain)

This article is dedicated to Puri (The one who gave idea ;))

If a sunny Day ends with a Rain, the thought reminds me the Pleasant smell of the Earth, I always want to capture all this flavors and store it, of course which is not possible…

So I wonder why the Earth gives pleasing scents when it’s raining or wet (like watering plants, In India we wash our front yards and put Rangoli/Muggu)…

If you are eager to know, then you need to read this…

Petrichor

As everything has a name, the pleasant scent is called Petrichor. After a lot experiments the Australian researches Sabel Joy Bear and Richard G. Thomas named it as Petrichor in 1965. This Word is derived from Greek, Petri means stone and chor means the fluid that flows in the veins of the gods.

Do you know why?

Australian Sabel and Richard described that, during dry times, some plants releases oils to save their babies(seeds) during dryness and duress (that is why oil is observed during the seed germination) which is absorbed by clay based soil and rocks.

Now what happens when it rains, this oil is released into air along with Geosmin (a metabolic by-product of certain bacteria)

As this is done in 1965, The MIT (Massachusetts Institute of Technology) researches in 2015 conducted once more this research and described that, this pleasant smell is due to air bubbles trapped by the rain drop as soon as they hit the ground.

Have you seen the fog or the Smoke during the start stage of rain, these naughty bubbles are shoot upwards and erupts as fizz, and suspends in air forming smoke and fog known as aerosols same like water produces aerosols when falls on water , more simple just like aerosols air fresheners.

Extra Care

These tiny particles not only releases the oils but the bacteria and viruses which are unnoticeable, that’s how we will start sneezing when its starts raining.
