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. | |

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. |

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 | |

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. | |
