Earth's Global Energy Budget
by Miklos Zagoni
NASA CERES mission has started twenty years ago
to examine the role of clouds in Earth's radiant energy system;
finally it discovered something more interesting:
small integer ratios between the global mean energy flows.
ONE unit in the system is
defined as UNIT ≡ OLR(all-sky)/9.
That is, we are finding ratios
between energy flows,
values of flows: the flux values are scaling with OLR.
Our 'quantum', UNIT
= 26.68 Wm-2, is not a universal
it is derived from the best CERES EBAF TOA 4.0 value of
The differences from whole
number multiples are
within the instrument calibration error of 4.3 Wm-2.
It seems the Earth's global annual mean flux structure is built up
from discrete blocks: 'wave packets' or 'atoms' ... it
This structure is neither a
CERES observation artifact, nor a coincidence:
it is there
in other independent global energy budget estimates,
such as Wild et al. (2015), constrained by BSRN observations:
Stephens et al. (2012) updated global energy balance:
Notice the role of LW CRE as UNIT flux!
L'Ecuyer et al. (2015), adjusted to energy and water cycle constraints:
It is evident that this 'atomic theory of climate'
has nothing to do with the Planck-constant nor
the Heisenberg-relations or the Schrödinger-equation.
It means only that the annual mean energy flows in the
global energy budget are 'quantal', F = N x UNIT,
such as the wave numbers of the electromagnetic radiation in a box.
As we trust these atomic structure, we are going to make
a long-term prediction below on this page.
This unit, as well as the ratios, have meaningful physical explanation;
see Presentations and Posters below.
The corresponding basic rules and equations:
SFC (SW + LW)
absorbed = 2 × TOA LW out (clear-sky)
SFC (SW + LW) absorbed = 2 ×
TOA LW out + SFC LW CRE (all-sky)
G (greenhouse effect) = SFC Net (turbulent fluxes) (clear-sky)
G (greenhouse effect) =
Solar Absorbed Surface (all-sky)
The first and the
fourth rules are evident characteristics of the geometric model,
their validity is being kept throughout the deduction;
the second and third rules are consequences for the resulting system.
For details, see NASA GSFC presentation, pp. 62-73.
The question is: Why the longwave cloud radiative effect, LWCRE,
plays the role of
UNIT flux in the integer multiples structure
(as it is apparent
in the above diagrams)?
A most curious point is the SW ATM/SFC = 1/2 breakdown.
But everything goes with 1/2...
From a surface perspective:
What is lost in the open
all-sky atmospheric window
is gained back by
the blanketing effect of clouds.
The answer to the above
question might be this:
The energetic role of clouds
is to close the
The resulted system is then an 'effectively IR-opaque'
where the F = N
× UNIT integer ratios are characteristics
of wave propagation in a cavity.
The integer ratios are proved to be valid by independent
global-scale clear-sky radiative transfer computations as well, with
According to these ratios, the global energy budget is strictly
and the fundamental flux structures for clear-sky and
all-sky are the followings:

Clear-sky integer table of fluxes:
Our results can be visualized by a simple geometric greenhouse model,
a planet surrounded by a 'glass-shell' atmosphere:
Let us emphasize that the validity of the revealed
is independent from
the validity of this proposed
We are convinced that the presented numerical ratios are not
from some hypothesis or theory; they are there in the
The apparent arithmetic simplicity of the energy flow distribution
is not a crude oversimplification of an otherwise complex reality,
but expresses the simplicity and clarity of the ruling principles.
CERES EBAF Ed4.0 monthly mean data, March 2000 - October 2017:
According to radiative transfer computations,
increasing CO2-concentration from 360 to 600 ppm
increases DLR about 1 Wm-2 without feedbacks (Kato 2018).
This gives +0.08 Wm-2 DLR change caused by CO2
As CO2 goes up about +20 ppm per decade,
this gives about 0.08 Wm-2 increase in DLR per
In contrast, CMIP5 models project + 2 Wm-2 DLR
increase per dacede.
This would require an
amplifying water vapor feedback multiplication factor of 25.
DLR goes with OLR:

(with our additions in dark textboxes):
EdMZ energy budget with OLR = 240.12 Wm-2
According to Wielicki et al. (1995), before CERES
it was known that the incoming solar = 340 Wm-2,
the reflected solar = 100 Wm-2 in all-sky and 50
Wm-2 in clear-sky,
with 240 and 270 Wm-2 outgoing LW, resp.
After 18 years of measurements, all-sky data are the same,
the clear-sky data have changed with 2 or 3 Wm-2.
Maybe a more spectacular achievement is the discovery of
direct TOA/surface energetic relationships
and the 'quantal' character of the flux system.
We think NASA CERES Science and
performed the quantum
measurement of our times
and discovered the discrete
("atomic") structure of Earth's energy flows.
