Air Quality Science and Technology
This certificate consists of the following two courses:
AOSC600 Synoptic Meteorology I
Atmospheric properties and observations, meteorological analysis and charts, operational numerical forecasts. Application of quasigeostrophic theory, baroclinic instability, midlatitude and mesoscale weather systems. Tropical meteorology.
AOSC624 Remote Sensing of Surface Climate
The theory and principles of remote sensing as applicable to earth observing satellites. Discussed will be current methods to interpret satellite observations into useful climate parameters. Emphasis will be placed on parameters that provide information about the climate close to the earth surface, and that can be inferred on regional to global scales. Examples are: surface temperature and reflectivity, radiation budgets, soil moisture, and vegetation cover.
Plus two electives chosen from:
AOSC625 Remote Sensing of the Atmosphere
Atmospheric radiative transfer applied to satellite observations. Physical basis of remote inference. Inference of surface temperature from satellite radiation measurements. Inference of temperature and moisture soundings (retrievals) from satellite radiation measurements. Errors in satellite retrievals. Applications and implications to numerical weather simulation and prediction.
AOSC637 Air Chemistry
Application of the techniques of thermodynamics, kinetics, spectroscopy and photochemistry to atmospheric gases and particles. Investigation of the global cycles of C, H, O, N, and S species; the use of laboratory and field measurements in computer models of the atmosphere.
AOSC633 Atmospheric Chemistry and Climate
The effects of human activity on atmospheric composition, focused on
global warming, the carbon cycle, air pollution, and the ozone
layer. Fundamentals of atmospheric chemistry (spectroscopy,
kinetics, isotopic analysis, and biogeochemical cycles) are related
to the modern understanding of climate change, air quality, and
ozone depletion, based on resources such as satellite missions,
field campaigns, and scientific assessments published by
international agencies. We also examine how society's energy needs
could be met, in the future, in a manner with less impact on
atmospheric composition than the present heavy reliance on combusion
of fossil fuels.
Prerequisites: CHEM131, MATH241 or permission of department.

Click for Additional Parking and Registration Information
Click here to access the Department of Transportation Services Web site for parking permit information. Parking permits are NOT required on campus for classes that beginafter 4 p.m.
Most students will follow the plan as described above. These students will be automatically enrolled for most courses and notified by email of the enrollment. For students who are not following the schedule, registration must be complete prior to the first day of class to avoid a penalty. A late fee of $20 will be assessed for registrations initiated on or after the first day of the course. Late registrants are responsible for payment of tuition and fees at the time of registration.
Note: Only students with prior permission from the Director may take courses outside the above plan. This is only allowed in situations where hardship would result if required to follow the schedule.
Cancellation of registration
Students who register for courses but later decide not to participate must cancel their registration prior to the first day of class. Notification of cancellation may be done online at Testudo. Failure to cancel registration prior to the first day of class will result in a financial obligation to the university regardless of student participation in courses. This includes all students automatically registered according to the cohort schedule.
Withdrawal from the program or from one or more courses
To withdraw from the program or to cancel registration in one or more courses, use the testudo website at Testudo. Withdrawals are effective the date the request is received. Students may withdraw from a course
at any time during the term without academic penalty, however, withdrawals are recorded on transcripts.
Academic service fees are nonrefundable when a student withdraws from a course. Tuition refunds are granted based on this schedule:
- There is a 100% refund for classes canceled prior to the first day of the course.
- There is a 70% refund for withdrawals processed within the first week (seven calendar days) from the first day of the course.
- There is a 50% refund for withdrawals processed within the first two weeks (14 calendar days) from the first day of the course.
- There is no refund granted for withdrawals processed after the first two weeks (14 calendar days or more) from the first day of the course.
Tuition refund policy
The University of Maryland will not automatically refund a credit balance. However, the student may request a refund by emailing the bursar or by calling 1-888-313-2404. Credit card payments are refunded by crediting the original credit card account. Refund requests are usually completed within two to three weeks from the date the request is received.
Courses cancelled by the University of Maryland
The University of Maryland reserves the right to cancel courses due to insufficient enrollment or other administrative reasons. Once a course is cancelled, students enrolled in the course are entitled to a full refund of the tuition and fees associated with that class. The university makes every effort to inform students of such changes as early as possible so there is an opportunity to make alternate course selections.
A recommended undergraduate background includes calculus, differential equations, linear algebra, calculus-based physics, and general chemistry.
All students must have an undergraduate degree from an accredited college or university in the US or an equivalent degree attained in a foreign country. A GPA of 3.0 (out of 4.0) is typically required.
The GRE is not required to apply for the Master of Professional Studies program in Atmospheric and Oceanic Science.
International students must take the Test of English as a Foreign Language (TOEFL) and apply for a J-1 (not F-1) visa.
Students are admitted to the program only for the Fall Term.
