We would love to be able to store all the climate data possible and have the ability to handle people's requests for data but we do not have the resources nor the manpower to handle this. The best way to get climate data is from the National Climatic Data Center or National Weather Service.
Like with climate data, we simply do not have the storage capacity to keep most imagery around for very long. Depending on the product, most images are regularly scoured within a few days to a week or so.
One exception is with our satellite imagery. We have partnered with Iowa State University to archive the bulk of our base satellite products. The archive can be found below, you'll need to navigate around to find the imagery you are looking for.
Most of our data originates from the National Weather Service or one of its branches (NCEP, FSL, SPC, etc.), with the exception of a couple of small data sets like NLDN or West Texas Mesonet observations. We receive all of our data over the Internet Data Distribution (IDD) system using the Local Data Manager (LDM) software. The LDM is a software package developed and maintained by the Unidata Program Center. Without the services and software provided by Unidata we would not be able to develop or maintain any of the realtime products found on this website.
At the College of DuPage (COD), you can earn an Associate of Science (AS) degree, though it is not specific to meteorology. However, COD offers a wide range of courses designed to provide a strong foundation and valuable preparation for your junior and senior years at a four-year institution. Additionally, we offer a Weather Preparedness Certificate, which equips students with specialized knowledge and skills to effectively understand and respond to severe weather events—a credential that sets you apart in the field. Many first- and second-year students at other schools don’t have access to the depth of meteorological experience and knowledge you can gain here. For more details, visit our Class Info section.
All participants are responsible for their own travel arrangements in getting to and from the College of DuPage. Once the storm chase begins, all travel arrangements are provided for by the college. There are several area hotels that are close to COD. College of DuPage also has a 6-room boutique hotel (Inn at Water's Edge) on campus. It is highly rated and allows you to walk to the storm chase meeting. See https://www.cod.edu/inn/
We presently offer a total of 4 trips each year. The only way to improve your chances is to be as flexible in your travel plans as possible. You stand a better chance to go on a trip if you are able to sign up for any trip, particularly if you are signing up late in the process when some trips may already be filled.
One of the key advantages of our program is that we provide the same thrilling experience as a professional storm chasing tour group—at a fraction of the cost! While a storm chasing tour company typically charges between $2,500 and $3,500 for a trip of similar duration, our program is significantly more affordable. Moreover, as educators, we ensure that every participant not only experiences the excitement of storm chasing but also gains a solid educational foundation in thunderstorms, tornadoes, and storm dynamics, earning college credit in the process. With a history of leading storm chasing trips since 1989, we proudly offer more experience and expertise than any major storm chasing tour operator in the world.
There are 14 spots for participants to go on each of our storm chases. A total of 18 people participate, including the instructor, an assistant, and two staff drivers.

No prior experience is required! Our courses are designed for all levels, from beginners to those with a strong interest in weather. We offer introductory and advanced courses to build forecasting skills, scientific understanding, and practical experience.
Yes! Our program prepares students for seamless transfer to top meteorology schools, including the University of Oklahoma, University of Illinois, and Northern Illinois University. Many students complete general education courses at COD before transferring to complete their bachelor’s degree in meteorology.
Students gain practical experience through NEXLAB (weather.cod.edu), storm-chasing courses, real-time forecasting projects, and fieldwork. Our Thunderstorm Lab provides opportunities to track severe weather in real time, enhancing forecasting skills beyond the classroom.
The College of DuPage Meteorology Program, through NEXLAB, operates one of the nation’s longest-running collegiate storm chasing programs, active since 1989. Students join faculty on field trips across the Great Plains to forecast, track, and observe severe storms safely. The program blends hands-on learning, team collaboration, and real-world meteorology.
Any COD student 18 years or older may enroll. Storm chasing is offered as two courses:
Enrollment in one of these courses is required to participate. All participants will pay for 2 in-district rates for storm chasing.
Trips typically last 9-11 days during the spring or summer semester. Students travel in vans, covering thousands of miles across the Plains. Expect long days of driving, storm observation, and occasional downtime.
Storm chasing is unpredictable. You may see spectacular tornadoes, or you may experience days with no storms at all. COD cannot guarantee tornadoes — not even rain. The only guarantee is that instructors will take students where conditions give the best chance for severe weather. On quiet days, the group may visit national parks, museums, or cultural sites.
“Down days” are spent repositioning for better weather or visiting cultural/natural attractions. Students are expected to stay engaged, helpful, and positive.
Storm chasing carries risks, including:
Safety is the program’s top priority. Only trained faculty drive in hazardous situations, and students must follow instructions at all times.
Packing is limited due to space in vans. Essentials include:
