Course Description
Intro to science of processes weather & climate change:
atmospheric structure and composition,
energy balance,
wind systems,
clouds and precipitation,
weather fronts, cyclones, weather forecasting,
thunderstorms and lightning,
hurricanes, monsoons,
climate and global warming,
ozone hole and air pollution

Course Description
Emphasis will be given to phenomena that have strong impacts on human activities.
The fundamental importance of physics, chemistry and mathematics will be noted.
Atmospheric Science is a branch of Applied Physics

Attendance Policy
Attendance is mandatory, and will be tallied throughout the term via the clickers.
After three unexcused absences prior to week 9, I reserve the right to submit to the Office of Curriculum and Registration an administrative drop from the course and assign a grade in accordance with UA policy.

Student Behavior
UA Code of Academic Integrity, Code of Conduct and Student Code of Conduct are enforced in this course.
Every student is responsible for learning these codes and abiding by them.

Grading Policy
Final grade will be based on scores from closed book/closed notes quizzes, a lab and final exam.
Quizzes will consist of multiple choice  questions and short answer questions.
Quizzes will cover new material presented through the end of the previous lecture day.
Extra credit questions given on some quizzes.
Extra credit impromptu ÒpopÓ quizzes given.

Grading Policy
There will be seven quizzes during the term. Dates for the quizzes are listed on the home page.
Students who arrive late on quiz days will be not allowed to take the quiz after the first student turns in her/his quiz. No Exceptions
The lowest score among the seven quizzes will be excluded from the course grade.
Therefore, no make-up quizzes.

Grading Policy - Lab
Each student will do one lab.
There will be two labs to choose from,
Determine the % of oxygen in the atmosphere
Determine the latent heat of melting of ice
At any one time, approximately 15% of the students will be doing Lab 1 and another 15% will be doing Lab 2.
You will be
given the lab equipment for approximately 2 weeks,
make your measurements,
return the equipment,
receive material on how to analyze your results,
write up your results and turn them in.

Grading Policy
Your lab will  be 20% of your grade
If your final exam score exceeds the average of your 6 best quizzes, the quizzes will comprise 50% of your term grade and the final 30%.
Otherwise, the quizzes will comprise 60% of your term grade and the final 20%.
CARROT: If your average on the 7 quizzes and your lab is 90% or higher, you will earn an exemption from the final and will receive an "A'' for the course.
No Extra Credit Projects. No Exceptions.
So Plan Accordingly!

Final Examination
Section 05 (2:00 pm TTh): ILC 120
Thursday Dec. 17, 2:00 pm - 4:00 pm
The final will consist of approximately 60 multiple choice questions and short answer questions.
A number of questions will be taken verbatim from the old quizzes.

Course Grading
Course Grading Scale
A 90% or higher
B 80.0-89.99%
C 65.0-79.99%
D 55.0-64.99%
E < 55.0%

Expectations
Every student is expected to:
Complete all of the assigned reading before the lecture (unless you hear otherwise).
Devote a minimum of 2 hours outside of class studying, reading, etc. for every hour of classroom lecture. Unit Credit Definition
Attend class daily, arrive on time, leave when class is dismissed (courtesy to peer students).

The Golden Rule
Instructor and students all show:
Mutual Respect!

Literacy Requirements
The writing requirement for this course is primarily the lab
There is a science literacy requirement:
Use scientific notation for writing numbers (especially rather large or small ones).
Specify units of physical quantities          (e.g. meters for elevation, etc.).
Attempt to quantify physical relationships.

Importance of Atmosphere
Necessary for a wide spectrum of features
Oceans
Clouds, Rain, Fresh Water
Erosion by Water and Wind
Life, Life on Land
Blue Skies, Red Sunsets, Twilight
Sound

Importance of Atmosphere
Point 1- Offers Protection
Consider surface temperatures
Without atmosphere?
0oF global average, large diurnal swings
Similar to the MoonÕs Climate
With atmosphereÉ
60oF global average, moderate diurnal (day to night) swings

Importance of Atmosphere
Point 2 - Offers Protection
Consider Surface Radiation
Shields against harmful UV radiation

Importance of Atmosphere
Consider Survival Time
Without Food
Þ few weeks
Without Water

To Understand the Atmosphere
Examine its interfaces
with land/ocean
with space

Local Weather and Climate: 
The North American Monsoon
Tucson gets half of its rainfall during the summer
Sonora, Mexico gets most of its rainfall during the summer
During summer, high pressure sets up to the east/northeast of Arizona which brings moisture in from the south
2009 monsoon has been poor with below avg rainfall
For a monsoon overview and daily forecast, see:

Monsoon moisture
Local:  2006 Monsoon Rainfall
Record water flow through the Sabino and Rillito Creeks on July 31, 2006
Rillito flow higher than Colorado river!

July 2009 set temperature records in Tucson

Atmospheric Composition
Permanent Gases
N2 and O2 are most abundant gases
Percentages hold constant up to 80 km
Ar, Ne, He, and Xe are chemically inert
N2 and O2 are chemically active, removed & returned

N2 and O2
Atmospheric Composition
Important Trace Gases
Carbon Dioxide CO2
CO2 Trend
H2O Vapor Variability
Precipitable Water (mm)
Aerosols
1 cm3 of air can contain as many as 200,000
non-gaseous particles.
dust
dirt (soil)
ocean spray
volcanic ash
water
pollen
pollutants

Aerosols - Volcanic Ash
Aerosols - Dust Particles
Aerosols
Provide condensation nuclei for water vapor.
Provide a surface area or catalyst needed for much atmospheric chemistry.
Aerosols can deplete stratospheric ozone.  They can also cool the planet by reflecting sunlight back to space.
