Statistics Prerequisite: Stat 301 or Stat 401 or E B F 472

Note: Meteo 474 is an elective course for undergraduate Meteorology majors.

Students who do not meet the prerequisites may be dis-enrolled during the first 10-day free add-drop period after being informed in writing by the instructor (see: (Links to an external site.)).  If you have not completed the listed prerequisites, then consult with the instructor.  


Computer Methods of Meteorological Analysis and Forecasting explores the computationally intensive statistical methods used in the development of automated weather analysis and forecasting systems. The focus of the course is on learning to develop and use artificially intelligent automated systems to perform data quality control, quantitative analysis of large meteorological data sets, and weather forecasting. Coverage will include the relevant statistical, mathematical, and computational methods including matrix operations, data quality control, regression analysis, neural network construction, decision tree growth, and forecast system verification. Students will leave the course with an understanding of how to efficiently develop accurate and robust statistical weather analysis and prediction systems. Thus, the course serves as a professional elective for those students wishing to pursue careers in statistical weather forecasting, meteorological data analysis, and associated fields. Meteorology 474 uses a project oriented lecture/lab format to provide students with hands-on experience in developing and testing weather analysis and forecast systems. Students will both code their own forecast system development programs and use off-the-shelf software designed for rapid development and testing of forecast systems. To tackle these assignments, students will use the computer laboratory facilities of the Meteorology Department and meteorological data sets of current interest. A key element of the resulting project reports will be an investigation into the origin of the observed forecast system errors. The class size is tailored to in-class training with the software tools and open discussion with the instructor and classmates. Grading will be based on the assignments and on a mid-term and final examination. 

Assessment Tools:
Required written/oral assignments

There will be homework assignments, which will count toward the course grade.

There will be an immediate 25% penalty for any assignment handed in late, a 50% penalty after six hours, and no credit will be given for an assignment handed in after the start of the next class.  Professor maintains the right to decline acceptance of a late assignment beyond a certain time.  Neatness, organization, technical soundness, spelling and grammar are important.  While students may consult with their classmates on these assignments, the final product should represent the student’s own work.

Discussion Participation will count for 10% of the grade.  Each week each student will receive a grade based on the quality of the questions asked and insights offered. 

Examination Policy

One midterm and one final exam will be given.  These will be open-book, individual written assessments.  No communication between students will be allowed, but you will have full access to online resources including Google and Wikipedia. 

Grading Policy

  • Discussion Participation 10%
  • Assignments 40%
  • Exam 1 25%
  • Final Exam 25%

Attendance and Participation: Students are required to attend class and participate in all exercises.  Active, thoughtful contributions to class discussions are required and will count towards 10% of your grade and 90% of your sanity.

Lecture notes will often be placed on CANVAS ( (Links to an external site.)), although students are ultimately responsible for their own note-taking.  It is reasonable that material covered during lectures, and through assignments, may appear on tests.  Reading the corresponding sections in the textbook may aid understanding of the course material. 

Academic Integrity Statement:

Academic integrity is fundamental not only to one’s experience at the university, but remains essential throughout one’s career.  Students are not to receive unauthorized assistance on any course quizzes or individual assessments.  Students are not to misrepresent the work of others as their own.  Serious offenses may warrant a zero on the assignment or assessment.

Students in this class are expected to write up their problem sets individually, to work the exams on their own, and to write their papers in their own words using proper citations.  Class members may work on the problem sets in groups, but then each student must write up the answers separately.  Students are not to copy problem or exam answers from another person's paper and present them as their own; students may not plagiarize text from any sources (e.g. papers or solutions or websites) written by others.  Students who present other people's work as their own will receive at least a 0 on the assignment and may well receive an F or XF in the course.  Please see: Earth and Mineral Sciences Academic Integrity Policy: (Links to an external site.), which this course adopts.  To learn more, see Penn State's "Plagiarism Tutorial for Students (Links to an external site.)."

If in doubt about how the academic integrity policy applies to a specific situation, students are encouraged to consult with the professor or TA. 

Course Copyright

All course materials students receive or to which students have online access are protected by copyright laws. Students may use course materials and make copies for their own use as needed, but unauthorized distribution and/or uploading of materials without the instructor’s express permission is strictly prohibited. University Policy AD 40, the University Policy Recording of Classroom Activities and Note Taking Services addresses this issue. Students who engage in the unauthorized distribution of copyrighted materials may be held in violation of the University’s Code of Conduct, and/or liable under Federal and State laws.

For example, uploading completed labs, homework, or other assignments to any study site constitutes a violation of this policy. 

Accommodations for Students with Disabilities

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Student Disability Resources (SDR) website provides contact information for every Penn State campus: ( (Links to an external site.)). For further information, please visit the Student Disability Resources website ( (Links to an external site.)).

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation: (Links to an external site.). If the documentation supports your request for reasonable accommodations, your campus’s disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations. 


Regular attendance is critical for building on the skills and knowledge developed throughout the class. Students who participate have a more complete understanding of the material presented and are more likely to succeed in the class. This is true whether your attendance is in person or remote.  The University recognizes that, on exceptional occasions, students may miss a class meeting to participate in a regularly scheduled university-approved curricular or extracurricular activity (such as field trips, debate trips, choir trips, and athletic contests), or due to unavoidable or other legitimate circumstances such as illness, injury, military service, family emergency, religious observance, participation in local, state, and federal government elections, or post-graduate, career-related interviews when there is no opportunity for students to re-schedule these opportunities (such as elections or employment and graduate school final interviews).  In all cases, you should inform me in advance, when possible.  Missing class, even for a legitimate purpose, may mean there is work that cannot be made up, hurting your grade in this class.  Students who encounter serious family, health, or personal situations that result in extended absences should contact the Office of the Assistant Vice President for Student Affairs (AVPSA) and Student Care and Advocacy for help: (Links to an external site.).  You should be prepared to provide documentation for participation in University-approved activities, as well as for career-related interviews.  You should submit to the instructor a Class Absence Form: (Links to an external site.), at least one week prior to the activity.
