Smells of Rain

I have written about smells until now, but today I will talk about smells of the rain.

It rained yesterday, and there was a rain smell.

As causative substances of rain smells, there are Petrichor and geosmin.

"Petrichor," which means "stone essence" in Greek, is a coined word created by Australian researchers, and expresses a smell that occurs at the beginning of the rain.

The reason of the smell is because some plants' oil is absorbed to the ground, and the rain emit it into the atmosphere.

"Geosmin," which means "smell of the earth" in Greek, expresses a odorous substance that occurs an odor after the rain.

Geosmin is also a causative substance of musty odors from sewers, and it's not a good smell.

I like rain smells in Nagano Prefecture, but don't like rain smells in Tokyo very much.

雨の匂い

これまで何度か匂いについて書いてきましたが、今日は雨の匂いについて書きます。

昨日は雨が降り、雨の匂いがしていました。

雨の匂いの原因物質として、ペトリコールとゲオスミンがあります。

ペトリコールはオーストラリアの研究者による造語で、ギリシャ語で「石のエッセンス」を意味し、雨の降り始めに発生する匂いを表します。

これは、特定の植物から生じた油が地面に吸着し、雨によって放出されることに起因しているとされています。

ゲオスミンはギリシャ語で「大地の臭い」を意味し、雨が降った後の独特な臭いの元とされています。

ゲオスミンは下水道から発生するカビ臭の原因物質でもあり、あまり良い臭いではありません。

私は長野県の雨の匂いは好きでしたが、東京の雨の匂いはあまり好きではありません。

  This also kind of implies you stopped being a vegetarian now.

  'To coin' is a good verb to use in this case I think.

• The reason of the smell is because some plants' oil is absorbed to the ground, and the rain emit it into the atmosphere.
• The reason for the smell is oil from plants being absorbed by the ground, and being released into the atmosphere by the rain.

  I'm not sure, but I think the verb 'to emit' isn't right here, since it isn't the rain itself that gives off the smell.

The smell of the rain in Warsaw is very refreshing, but the city isn't anywhere as dense as Tokyo.
