Some science.

Has anyone noticed how rich night air is close to ground. Gravity is pulling the air down towards the ground at night. Sunlight disperses it during the day.

This is dependant on local conditions at night time.

Usually between 12am to 7am. You have to kneel down or lie down to smell it.

To test it

Walk to the front door and breath in normally but become more aware of the air your breathing in.

Open the door, lie down on the floor and breathe in again.

You might have to repeat this test a few times depending on local conditions.

but you should be able to smell the difference.

I made some notes on it which I’ll post later.

Let me know how the test goes.

Covid patients might benefit from enriched night air. If it was collected stored and released in an oxygen mask.

If night air is enriched, how much percentage of different gasses?

I’m fairly certain that gravity also operates during daylight hours.

Correct.

Sunlight competes with gravity during the day and will disperse the night air layer from compressing close to the ground.

At night time there is no sunlight, so gravity will pull the night air down without competition from the sun, hot air rises. so the heat will continue to disperse after sunset.

After the heat has dispersed enough, around 4 hours after sunset, the night layer will begin to form again, then disperse again at sunrise.

I think this is a recycled thought. I reckon you said something about this a couple of weeks ago.

Could this “Rich Night Air” be the interaction between dew and the substrates it is forming on?

Couple of observations:
More humid at night.
Cooler at night especially in hollows.
Both of which produce a pleasant environment on calm warm evenings.

With sight swiched down low in low light situations, other senses are felt more strongly.

My thoughts are that you’re correct
attaching the phenomena to an inversion layer
which is usually attributed to temperature differences
which are also effected by GRAVITY (cooler drier air sinks)

I’m thinking “rich” as in smell, such as the smell of damp earth.

From https://theconversation.com/heres-why-soil-smells-so-good-after-it-rains-135978

“Did you ever wonder what causes that earthy smell that rises after a light summer rain? That mysterious scent has been called petrichor. The main component of petrichor is an organic compound called geosmin, which lingers around moist soil. Geosmin comes from the ancient Greek “geo”, meaning earth, and “osme”, meaning smell. We use this scent as an ingredient in perfumes”

“Scientists have known since the 1960s that geosmin is made by microorganisms in the soil, primarily by bacteria with the scientific name Streptomyces. These bacteria are abundant in soil and are among nature´s best chemists, as they make a wide range of molecules from which many antibiotics derive. … Streptomycetes normally grow as mycelium – a network of long, branching cells that entwine with the soil they grow in. … Our new finding is that spore production also includes the release of those earthy odorants that are attractive to springtails – and that helps spread the spores.”

“Next time you encounter that earthy smell, let it be a reminder of the fascinating and extremely valuable bacteria that thrive in the ground beneath your feet. You might be listening in on an ancient type of communication between bacteria and the creatures that live with them in the soil.”

As I indicated earlier in the thread, it might be settling dew that releases these smells. That might explain the late-night observations.

Surely it’s just that cool air drops and warm air rises.

Most of the summer here, there is no cooling down and refreshing at night. This year we’ve had a bit of rain so to venture outside at night, one usually can’t stay there long enough unless one has so much mosquito repellant to render the freshness of the air null and void.

Fair enough, but I think of it in more detail.

Thermal infrared radiation from solid surfaces during cloudless nights cools the solid surfaces (soil, vegetation, buildings) below the temperature of the adjacent ambient air. This is known as undercooling and is one of the two processes producing dew.

In still air, due to conduction and convection, this slowly cools the air adjacent to the ground up to, as TN suggests, about waist height. Because relative humidity increases as temperature decreases, under favourable atmospheric conditions this also produces “ground fog”, but before fog forms it wets the ground because the ground is colder, releasing smells from the ground and vegetation.

During the day, the temperatuire in the atmosphere normally decreases with height, because the atmosphere gets less dense with height so the decrease in temperature follows from Boyle’s law. But from midnight to dawn the ground is colder so the temperature a short distance above the ground increases with height in the atmosphere. This nightly process is known as an “inversion” because the change in telperature with height is inverted.

Without going into too much detail, this inversion increases atmospheric stability near the ground, suppressing air turbulence and reducing the wind speed. This acts to trap any smells and moisture from the ground and low vegetation inside the waist-high air layer above the ground, as TN observes.

I could go on about how this cold air accumulates in dips and hollows, and slowly flows down towards valleys. And then explain futher how ground fog rises from the gound in the morning until it burns off during the day, but that’s going a bit far for this thread.

17 Can be tested by breathing in air close to the ground.
18 inversion layer could increase the enriched night air layer by increasing the air pressure
19 Observation can be simple or complex
20 You don’t need cannabis to observe local phenomena.

Really gone.

Have you tested worm farts?

Can’t say I have.

Do you recommend it?

I said I would post my notes, here there are.

1 forms at night between 12 am 6 am
2 Sunlight disperses it during the day, heat rises.
3 Is time time early morning specific.
4 Is local topology specific.
5 Is local conditions specific.
6 Is invisible like an inversion layer.
7 Forms by gravity air pressure in lack of sunlight.
8 Is difficult to notice
9 Forms when people are asleep.
10 Does not from everywhere.
11 Does not form when its windy.
12 Does not form when its raining.
13 Forms mostly while air is still.
14 Radiant heat stops the layer from happening after sunset to around 12am.

It is a possibility he may have left out.

At 3 a.m. I had a sniff of the air first at 1600 mm and then at 300 mm. There was no noticeable difference.

“Rich” is not a scientific term. Can you elaborate on how you mean it?

I’m thinking “rich” as in smell, such as the smell of damp earth.

From https://theconversation.com/heres-why-soil-smells-so-good-after-it-rains-135978

“Did you ever wonder what causes that earthy smell that rises after a light summer rain? That mysterious scent has been called petrichor. The main component of petrichor is an organic compound called geosmin, which lingers around moist soil. Geosmin comes from the ancient Greek “geo”, meaning earth, and “osme”, meaning smell. We use this scent as an ingredient in perfumes”

“Scientists have known since the 1960s that geosmin is made by microorganisms in the soil, primarily by bacteria with the scientific name Streptomyces. These bacteria are abundant in soil and are among nature´s best chemists, as they make a wide range of molecules from which many antibiotics derive. … Streptomycetes normally grow as mycelium – a network of long, branching cells that entwine with the soil they grow in. … Our new finding is that spore production also includes the release of those earthy odorants that are attractive to springtails – and that helps spread the spores.”

“Next time you encounter that earthy smell, let it be a reminder of the fascinating and extremely valuable bacteria that thrive in the ground beneath your feet. You might be listening in on an ancient type of communication between bacteria and the creatures that live with them in the soil.”

Paul Kelly wrote a song entitled; Petrichor

Covid patients might benefit from enriched night air. If it was collected stored and released in an oxygen mask.

If night air is enriched, how much percentage of different gasses?

…so it merits having a test…

I wasn’ae far off with worm farts then?

Surely temperature is the main thing

Please keep posting! Please please!

I rely heavily on you for all my science news.

I’m sure Tau will post again, he was just a bit disgruntled earlier.

He does need a bit of re-gruntling.

Recovered from being disgruntled.

I think there is science to be found here, its a very subtle weather phenomenon for sure.
