Rasmussen Systems LLC

Rasmussen Systems is a Colorado Limited Liability Company engaged in fundamental and applied research in severe storms, and especially tornadoes. Rasmussen Systems is based near the Grand Mesa, southeast of Grand Junction, Colorado, at a site powered only by solar photovoltaic and micro-hydro power. That means that all of the research and development conducted at Rasmussen Systems is made possible by renewable energy.

I (Erik Rasmussen) formed Rasmussen Systems to host a variety of research and consulting activities. My weather research is supported by the National Science Foundation and by Rasmussen Systems. I also recently consulted for the National Severe Storms Laboratory, and performed applied research and development for a major private weather information provider.

You may wonder why there is a PayPal Donate button to the right. There are two primary reasons. This web site makes available software released under the Creative Commons licenses. The development of this software required countless hours of work for which I receive no compensation (NSF support is half time). I encourage users of this software to make a donation of any size they feel is appropriate. Further, if you think the research I do is in the public interest, don't make me do it for free!

I have a strong interest in the issues surrounding global sustainability, alternative energy, peak resources, and environmental stewardship. That is my motivation for trying to live a bit more simply and away from what I view as unsustainable arrangements. There are all sorts of pros and cons to the way I have chosen to live, but that's a different web site! One of my biggest concerns is the preservation and dissemination of scientific knowledge in the face of increasing complexity and fragility of our overall research and education endeavor.

In support of the basic research of the collaborative group, I develop and maintains tools using Qt, the Visualization Toolkit, and ParaView. The group is currently exploring VisTrails as a tool to enhance repeatability and training of new researchers. I am experienced in coding in C++, Objective C, C, Pascal, IDL, and a few other languages.

I was a member of the Steering Committee for the VORTEX2 (Verifications of the Origins of Rotation in Tornadoes EXperiment-2) held in the central U. S. in 2009-2010, and was one of the Field Coordinators for that experiment. I currently serve on graduate advisory committees at the University of Oklahoma.

Collaborative Team

The research reported on this site is largely the result of a productive, long-term collaboration between Erik Rasmussen, Jerry Straka, Katharine Kanak, and Bob Davies-Jones. The collaboration has benefited greatly from the work and talent of our past and current graduate students.

Acknowledgments

We gratefully acknowledge the support of the National Science Foundation, Atmospheric Sciences, of the research reported on this site. Support has been through grants AGS-1036237, ATM-0823794, ATM-0733531, ATM-0340693, ATM-0003869, and ATM-9617318.

Until 2001, Erik Rasmussen received research support from the National Severe Storms Laboratory. Additionally, NSSL has contracted with Rasmussen Systems to investigate Coordination and Communications technologies useful in mobile field experimentation, and has supported the development of the SASSI software application first deployed in VORTEX2.

This work would be impossible without the support of Lisa Rasmussen. Science research outside of the university or laboratory setting is not a highly compensated profession!
