Planet Surface Rotational Warming Phenomenon
Earth receives 29% less SW EM energy from sun than Moon per sq. meter. It is almost a one third less!
With the two thirds of SW EM energy Moon receives, Earth appears to be a much warmer on average surface temperature than Moon planet.
How it happens Earth receiving only the two thirds of SW EM energy Moon does, for Earth to be a much warmer than Moon planet?
Because no one disputes Earth has 29% less SW EM available energy per sq. meter to interact with than Moon has.
What we observe here is that for 29% less available energy per sq. meter Earth is, nevertheless, a much warmer planet!
Earth's surface is on average much warmer than Moon's because of planet Earth's 29,5 times shorter diurnal cycle, which is a result of Earth's faster rotational spin. Also, planet Earth is covered with water, and water has 5 times higher specific heat than the regolith covered lunar surface has.
It is the Planet Surface Rotational Warming Phenomenon we observe here. It states that planets' mean surface temperatures (everything else equals) relate
as their (N*cp) products' sixteenth root.
Mars and Moon the satellite measured mean surface temperatures comparison: 210 K and 220 K are very close
Very interesting !
Mars and Moon satellite measured mean surface temperatures comparison: 210 K and 220 K
Let's see what we have here:
Let’s compare then:
Tsat.moon = 220K
Moon’s albedo is amoon = 0,11
What is left to absorb is (1 – amoon) = (1- 0,11) = 0,89
Tsat.mars = 210 K
Mars’ albedo is amars = 0,25
What is left to absorb is (1 – amars) = (1 – 0,25) = 0,75
Mars /Moon satellite measured temperatures comparison:
Tsat.mars /Tsat.moon = 210 K /220 K = 0,9545
Mars /Moon what is left to absorb (which relates in ¼ powers) comparison, or in other words the Mars /Moon albedo determined solar irradiation absorption ability:
( 0,75 /0,89 )¹∕ ⁴ = ( 0,8427 )¹∕ ⁴ = 0,9581
1. Mars /Moon satellite measured temperatures comparison ( 0,9545 ) is almost identical with the Mars /Moon albedo determined solar irradiation absorption ability ( 0,9581 )
2. If Mars and Moon had the same exactly albedo, their satellite measured mean surface temperatures would have been exactly the same.
And this is very interesting !
Mars rotates N = 0,9747 rotation /day
Moon rotates N= 1 /29,5 rotation day
Mars solar flux S = 586 W/m²
Moon S = 1361 W/m²
Mars is at 1,53 AU distance from the sun,
Moon is at 1 AU from the sun.
That is why Mars receives much weaker (586 W/m²) vs (1361 W/m² ) than Moon solar flux.
Nevertheless, Mars' surface develops almost the same average surface temperature ( 210 K ) as the Moon ( 220 K ).
Both Mars and Moon do not have atmosphere.
It is the Solar Irradiated Planet Surface ROTATIONAL Warming Phenomenon which does the job.
We observe here the solar irradiated Planet surface ROTATIONAL WARMING phenomenon!
Mars is at 1,524 AU distance from the sun and the solar flux on the top is S = So*(1/R²) = So*(1/1,524²) = So*1/2,32 .
(1/R²) = (1/1,524²) = 1/2,32
As a result the solar flux on the Mars' top is 2,32 times weaker than that on the Moon.
But, Mars rotates much faster, than Moon.
Mars performs 1 rotation every 24,622 hours, or 0,9747 rot /day
Moon performs 1 rotation every 29,531 earth days.
So, Mars rotates 29,531 *0,9747 = 28,783 times faster than Moon.
Interesting, Mars is irradiated 2,32 times weaker, but Mars rotates 28,783 times faster.
The rotation difference's fourth root is
(28,783)¹∕ ⁴ = 2,3162
And the irradiating /rotating comparison
2,32 /2,3162 = 1,001625
It differs only 0,1625%
It is almost equal!
It is obvious - the Mars’ 28,783 times faster rotation equates the Moon’s 2,32 times higher solar irradiation. That is why Mars has almost the same satellite measured mean surface temperature as Moon.
Tmean.mars = 210 K
Tmean.moon = 220 K
What we observe here is the solar irradiated Planet surface ROTATIONAL WARMING phenomenon!
