The document discusses insolation, or incoming solar radiation to Earth. It provides details on:
- The sun is the main source of energy for Earth, emitting electromagnetic radiation.
- As radiation passes through the atmosphere, some of it is absorbed, scattered, or reflected by gases, particles, and clouds. This affects the amount of solar energy that reaches the surface.
- Insolation levels vary based on latitude, with the greatest amounts reaching Earth's surface at 30-40 degrees latitude in each hemisphere, and decreasing towards the poles. Seasons also impact insolation levels across different latitudes.
- Absorption by gases like ozone and water vapor is wavelength-dependent, with some wavelengths absorbed
Earth's energy budget refers to the tracking of how much energy is flowing into and out of the Earth's climate, where the energy is going, and if the energy coming in balances with the energy going out. The Earth receives energy from the Sun, and it also reflects and radiates energy back into space. All of the energy that warms the atmosphere, oceans and land must be radiated back into space in order to maintain our current climate. If the amount of energy radiating back into space is decreased by even a very small amount, it can lead to warming. It is believed that increasing levels of carbon dioxide in the atmosphere has a 'greenhouse effect' of reducing the amount of energy radiated into space.
Milancovitch Cycles explains variations in eccentricity, axial tilt, and precession of Earth. The climate changes caused by changes in the position of the Earth in comparison to the Sun. This explains the formation of ice ages.
Horizontal Distribution & Differences of Temperature
If the Earth was a homogeneous body without the present land/ocean distribution, its temperature distribution would be strictly latitudinal. However, the Earth is more complex than this, being composed of a mosaic of land and water. This mosaic causes latitudinal (horizontal) zonation of temperature to be disrupted spatially.
Climatology is the science of studying the average atmospheric conditions of a region in long-term perspective. The primary goal of Climatology is to study the unique characteristics of atmosphere in controlling the global climate, origin, types of climates, causes and processes influencing the climatic variations, elements of weather and the impact of climate on humans or vice-versa.

1. INSOLATION
Sun is the main source of energy for Earth. Radiation of solar

Diameter of sun – 1382400 kms (109 times more than earth)
Velocity of electro magnetic short waves – 297600 km/ second
Time to reach earth – 8 min 20 sec
Mass – 332000 times that of earth
Average density – 1.41 earth – 5.52
Surface temperature – 5500 to 6100 oC
Energy coming to earth – 1/ 2 billionth equal to 23 billion HP
Solar constant – 1.94 gram cal / sq. cm. / minute
There Hydrogen is changed in to Helium through nuclear fusion.
Electro magnetic waves – 1. longer – Infrared waves
2. shorter - U.V. rays
2. ELECTROMAGNATIC SPECTRUM
The solar energy radiated from the sun in the form
of electromagnetic wave is called electro
magnetic radiation.
The energy from the sun or electromagnetic
radiation waves are expressed in terms of
wavelength (L).
The number of radiation wave passing through a
certain point per unit time (one second) is called
wave frequency.
Wave frequency is generally expressed as wave
cycle per second, expressed in hertz,
kilohertz(1000 hertz), megahertz(1000,000 hertz)

7. Factors affecting Insolation
1. Angle of sun’s rays - Angle of incidence – the
angle at which the insolation strikes earth’s surface
• Altitude of sun determines the angle of incidence.
• The higher the sun is in the sky, the higher the angle
of incidence and more insolation is absorbed.
• A lower angle of incidence more insolation is
reflected and less is absorbed.
equator pole
8. Earth's atmosphere reduces the amount of
insolation striking earth's surface.
Earth's atmosphere and tilt combine to explain
variation in received solar radiation.
9.
10. 2. Length of day and night
• Duration of insolation: The number of daylight
hours at a given location. This varies with latitude
and season.
• The longer the earth receives light the more
insolation it gets.
• If I hold a lamp at a great distance from an ice cube,
for a long time will the ice cube eventually melt?
• The longer the day, the more insolation reaches the
earth.
• This is a Direct relation ship.

14. 5. Transparency of the atmosphere –
reflection from dust particals, salt particals and
smoke particals reflecting short wave solar
radiation to space.
reflection from the cloud tops also deflects the
amount of solar radiation that would be
otherwise available to earth.
transparency also related to latitude –
• Oblique rays
• Vertical rays
15. Latitudinal and Seasonal variation / distribution
• Amount of insolation received by earth decreases towards pole.
• Temporal variation at different latitudes at diff times of a year.
• BAUR & PHILLIPS – solar radiation reaching at outer limit of
atmosphere is more than the amount received at earth surface.
• But this is the fact that greater portion of insolation is lost while
passing through the atmosphere due to the effect of scattering,
reflection, absorption, cloudiness.
• SUMMER SOLSTICE – (21 June)- maximum insolation reaches at
outer limit of atmosphere at North pole. But maximum energy
received at the ground surface at 30 to 40 latitude. Because of
minimum amount of cloudiness due to presence of subtropical high
pressure belt and anticyclone conditions. But at pole the insolation
become so low that they received about 40 % of the amount
received by the Equator.
16. The summer solstice
occurs when the
Northern Hemisphere
is tipped towards the
sun. The winter
solstice occurs when
the Northern
Hemisphere is tipped
away from the sun.
17. The globe is divided in to three zones on the basic of
amount of insolation received during the course of year
Equatorial: intense insolation, day and night roughly equal
Tropical: high annual insolation, marked seasonal cycle
Subtropical: large annual insolation; strong seasonal cycle
Mid latitude: strong seasonal contrasts in insolation and length of
day
Arctic/subarctic, Antarctic/ subantarctic: enormous variation in
annual insolation, extreme variation in day length
Polar: greatest seasonal insolation contrasts, 6-month day, 6-
month night

20. EFFECT OF ATMOSPHERE ON INSOLATION
The electro magnetic solar radiation or incoming
short wave solar radiation has to pass through thick
layer of atmosphere, hence it is partly absorbed,
scattered, and reflected.
21. ABSORPTION
• The energy radiated from the sun towards earth.
• It is 1/ 2 billion part reaches the earth.
• If it is consider 100% then 14% of energy is absorped
by atmospheric gases and water vapor.
• Ozone is on large extent, O2, CO2 are very limited
extent, nitrogen on poor absorber of insolation.
• Process of absorbtion is selective in nature.
• O2,O3 – absorb shortest wave length 0.02 to0.29
micron
• Ozone – U. V. rays wave length of 1000 to 4000
angstrom
• Water vapor – wave length of 0.9 to 2.1 micron
• The energy absorb transmitted in to internal molecular
motion which causes a rise in temperature.
22. SCATTERING
• 23 % of insolation scattered in atmosphere by dust
particals and Haze.
• 6 % sent back to atmosphere
• 17 % reaches to earth.
• Process of scattering is selective one.
• When the diameter of dust particals and molecules
of atmospheric gases is shorter than the wave
length of the solar radiation waves.
• Blue light is more scattered than red light.
• Due to scattering effect sky appear blue and at the
time of sunrise & sunset sky appears reddish.
23.
24.
25.
26. DIFFUSION
• Diameter of the particals are larger than the
wavelength, true scattering dose not possible
and the effect of diffusion occur.
• it is effective for all wave length.
• non selective in nature.
• Eg – light reflected from clouds is pure white.
• the twilight are longer duration in high latitudes
due to diffusion.
27. REFLECTION
• 27 % radiation reflected back is called as reflection
of light.
• It does not play any roll for heating the atmosphere.
• Diameter of dust particals and molecule of water
vapor is longer than wave length of incoming solar
radiation reflection takes place.
• Some energy remains in lower atmosphere.
28.
29. ALBIDO
• The portion of incident radiation energy reflected
back from the earth surface is called Albido.
• Various data received so far indicate the Earths
average albido varying between 29 % to 34 %.
Fresh snow – 80 – 85 % Forest 5 – 10 %
Old snow 50 – 60 % water (sun near horizon) 50 – 80 %
Sand 20 – 30 % Thick cloud 70 – 80 %
Grass 20 – 25 % Thin cloud 25 – 50 %
Dry earth -15 – 25 % Wet earth 10 %
