CONTENT/DESCRIPTION
This course is meant to expose the student to the elementary part of Atmospheric Physics. It introduces the trigonometric relationships between the sun-earth line and the position of an inclined surface. Because this material does not require a priori knowledge of any aspect of solar radiation, it was considered appropriate at the beginning. The characteristics of blackbody radiation, will be discussed, it focuses on the solar constant and .its spectral distribution. It also deals with extraterrestrial radiation. Detailed formulations treating instantaneous, hourly and daily quantities of radiation incident on inclined planes are presented.
A cloudless-sky atmosphere and its optics will be treated. The first part of this section describes earth's cloudless-sky atmosphere, concentration of the various molecules, vertical distribution of ozone and its seasonal variation, vertical distribution of water vapor, evaluation
of the perceptible water through its partial pressure or dew-point temperature,
and description of the aerosols.
CONTACT SCHEDULE: Friday 10am-12pm
Week I: INTRODUCTION TO THE COURSE.
At the end of the lectures, students will have an overview of the course; describe the various definitions, concepts and terminologies of units, dimensions and vectors.
Week II: SUN-EARTH LINE AND THE POSITION
This week, we discuss the physics of the sun, the nature of the radiant energy emanating from its surface, spectral distribution, and the total quantity of this energy arriving just outside the earth's atmosphere. It introduces the trigonometric relationships between the sun-earth line and the position of an inclined surface. Because this material does not require a priori knowledge of any aspect of solar radiation, it was considered appropriate at the beginning.
Week III: THE CHARACTERISTICS OF BLACKBODY RADIATION
In this week, the radiation from the sun will be compared with
that from a blackbody at an equivalent temperature. Therefore, it is useful
to note down some fundamentals of blackbody emission.
WEEK IV: EXTRATERRESTRIAL RADIATION.
it focuses on the solar constant and .its spectral distribution. It also deals with Detailed formulations treating instantaneous, hourly and daily quantities of radiation incident on inclined planes are presented.
WEEK V: A CLOUDLESS-SKY ATMOSPHERE AND ITS OPTICS
The rate of energy propagation in a given direction is required. This is described in terms of the intensity of radiation. In order to discuss intensity. It is necessary to explain the concept of solid angle. The solid angle is defined as the ratio of the area dS of a spherical surface to the square of its radius R.
WEEK VI: EARTH'S CLOUDLESS-SKY ATMOSPHERE
A knowledge of solar distribution provides a design input for the better thermal environment of a spacecraft and for the selection of suitable materials exposed to solar radiation. The spectral distribution of radiation arriving on the surface of the earth is indeed a function of its extraterrestrial distribution and the atmospheric constituents.
WEEK VII: MID-SEMESTER ASSESSMENT
Students will be examined in the areas that have so far been covered in the Semester. This will afford students an opportunity of a revision of all topics that have already been taken.
WEEK VIII: CONCENTRATION OF THE VARIOUS MOLECULES IN THE ATMOSPHERE
The actual composition and concentration of the constituents of clean,air
vary with geographic location, elevation, and season.
WEEK IX: VERTICAL DISTRIBUTION OF OZONE AND ITS SEASONAL VARIATION
In the upper atmosphere, ozone is created mainly by ultraviolet solar radiation. On the ground, it is formed through decomposition of nitrogen oxide that enters the atmosphere from factory smoke and forest fires,
WEEK X: VERTICAL DISTRIBUTION OF WATER VAPOR, EVALUATION OF THE PERCEPTIBLE WATER
Water can exist in the atmosphere in three states, as gas, liquid, and ice. Water in gaseous state is called water vapor. The amount of water vapor present in the atmosphere can be defined in a number of ways.
WEEK XI: DESCRIPTION OF AEROSOLS.
An aerosol is a small solid or liquid particle that remains suspended in the air and follows the motion of the air within certain broad limits. Obviously, rain, snow, and hail are not aerosol particles.
WEEK XII: REVISION EXERCISE
This week is specifically left for revision of all the topics and subtopics covered during the course. Students are required to ask any question related to the course while the lecturer will also ask the students questions to determine the level of understanding of the course. The revision is expected to present to the students the practical approach to the field of mechanics.
