QUESTIONS ABOUT RAIN
Rain smells cool, wet and quietly mineral, with an earthy undertone that seems to hang over soil and pavement once the first drops have fallen. The air feels cleaner and heavier at once, damp rather than sharp. During a long shower the impression softens into a broad, watery freshness, and it lingers for a while after the clouds pass. It is easily confused with the narrower earthy burst of first rain on dry ground.
People notice it when stepping outside after a downpour, on city pavements darkening with water, and along forest paths where wet soil scents the air. It is especially striking after summer heat, when the first shower breaks a dry, warm spell.
Typical settings: after summer heat, city pavement, forest soil.

One VERIFIED scientific claim from one published source is recorded for this entry: Petrichor and rain on dry ground. This claim could not be checked against its source's own words, because no abstract or other summary of the source was available; it says only what is shown in its scope.
SmellBook treats rain as an atmospheric experience rather than a single ingredient.

Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.
Scientific evidence · 1 claim
VERIFIED means the claim rests on a registered published source whose citation SmellBook checked. No abstract or other summary of that source was available, so SmellBook could not compare the claim's wording with the source's own words.
Petrichor and rain on dry ground
The scientific literature has used the term petrichor for the characteristic earthy odour associated with rain acting on dry mineral and soil environments.
Historical scientific framing of petrichor; this does not mean every rainy environment has one identical chemical profile.
How this was found: Broad account. A broad statement about how an aroma forms, how it is studied or what a term means, rather than one measurement. Source: primary study.

FOR RESEARCHERS AND EDITORS
Identity, revision history, corrections and how to cite Rain.
CULTURAL: This entry's associations depend on context, language, memory or culture; its description and smell words are editorial. It says nothing about research or historical evidence; evidence for this entry is shown separately: VERIFIED.
A state says how an entry is met, such as wet, aged or roasted. It does not create a new smell, and it adds no scientific fact by itself: states marked EDITORIAL come from the entry's own records, and only those marked VERIFIED are reported by a VERIFIED claim.
