Lowell Digisonde International


LDI's Mission: To design, develop and manufacture advanced research instrumentation for geoscience exploration; to deploy such instrumentation around the globe on the ground and in space for the purpose of collecting data for furthering the understanding of Earth's environment.

Lowell Digisonde International, LLC (LDI) was founded in December of 2009 by Prof. Emeritus Bodo W. Reinisch, the former director of the Center for Atmospheric Research at the University of Massachusetts Lowell, who with his team has revolutionized the science of radio sounding from ground (Digisonde® Portable Sounder) and space (IMAGE/RPI). These instruments are essential for space-weather monitoring and ionospheric modeling.

Dr. Reinisch has received numerous awards for his achievements in his field, most recently the Appleton Prize for his outstanding contribution to studies in ionospheric physics that was presented at the opening ceremony of the URSI General Assembly and Scientific Symposium on August 14, 2011 in Istanbul, Turkey.

In addition to Dr. Reinisch, a team of top-level scientists and engineers is contributing to LDI’s success. They devote much of their efforts to Research and Development of new HF radar applications as well as new scientific instrumentation.
