What is the OS411 series?Welcome to the OS411 series of self-instructional courses in air quality modeling! Please read this page carefully before beginning any of the courses. A table of contents is provided below to assist with navigating this page!
What is this program?The OS411 series consists of six courses presented as an interactive learning opportunity for professionals who wish to develop a solid foundation in the technologies, techniques, and tools of air quality modeling and the use of computational science in air quality analyses.
What are the six courses?The six courses are identified by the "OS411" course number, followed by the letters A through F. Each course is a "stand-alone" course: that is, each course is a complete program of instruction. Courses after the first course, however, "build" on each other. In other words, participants are expected to be comfortable with the information presented in OS411A prior to beginning any of the subsequent courses.
The six courses, with brief descriptions, are as follows. More detailed information about each course, including the number of credit hours, is available on the top page of each course:
How do I begin taking a course?Prior to beginning any of these courses, the student should read carefully the reading on Setting up to use the course materials. In this reading, we discuss types of browsers, general navigation guidelines, browser plug-ins, and other important information designed to make your experience more productive and enjoyable. In addition, you can read more about the structure and specific content of each course. An estimate of the time required to take each course is also provided. Back to the top of the page
For whom are these courses designed?These courses are designed for the working professional, looking to begin his or her education in the area of atmospheric sciences, meteorology, and/or air quality modeling. The courses are designed to provide a self-paced, self-assessed program of instruction. There is no start or stop date: participants work through the materials as they desire. In designing these courses, we envisioned a early- or mid-career professional, with at least a bachelor's degree, probably in science, who has an interest either personally or professionally in the subjects presented in one or more of these courses.

How do I register? How do I get credit?Students not desiring "credit", either in the form of CEUs or PDHs, are not required to register for any of these courses. Students who do wish to receive some type of formal acknowledgement of their completion of one or more courses must register with the Air Pollution Training Institute (APTI). Registration links are provided below:

Students not desiring "credit", either in the form of CEUs or PDHs, are not required to register for any of these courses. Students who do wish to receive some type of formal acknowledgement of their completion of one or more courses (i.e. CEU/PDH credit and/or certificate) must register at one of the links provided below depending on their place of employment.
If you are a United States state, local, or tribal air pollution control official, register with the Air Pollution Training Institute (APTI).
Students desiring credit are provided credit only after successful completion of the 50-question, "closed-book" multiple choice exam. This exam will be sent to your proctor via postal mail after you have completed the course materials. You must secure the services of a proctor who has been approved by the institution with whom you registered. The proctor will administer the exam and return it to the appropriate person for scoring. A minimum grade of 70% is required for credit to be awarded. No "partial" credit or acknowledgement of partial completion of the course modules is provided.
What if I have questions about this program that are not answered here or in the Setup reading?You can either consult the "Frequently Asked Questions (FAQ)" page, or contact us with your questions!
