We design and manufacture quality meteorological instruments for scientists committed to accurate and precise environmental measurements

In the Beginning

In the late 1980s scientists from the National Oceanic and Atmospheric Administration approached the team about developing improved technology for measuring ultraviolet radiation, which is critical to understanding stratospheric ozone depletion.

The result was one of the company`s flagship products, the UVB-1 pyranometer, with patented thermal-stabilization technology to ensures a uniform response from instrument-to-instrument. Based on results from an independent National Institute of Standards and Technology evaluation, the United States Department of Agriculture (USDA) selected the YES UVB-1 as a core instrument in its UV-B monitoring program. The success of this first product, along with the company`s reputation for state-of-the-art methods and a commitment to quality, spawned further research and development in the areas of scientific and industrial instrumentation and also led to collaborative projects with government and educational institutions. One such relationship is the ongoing research between engineers at YES and scientists at the Atmospheric Sciences Research group in the Center for Environmental Science and Technology Managementon the campus of the State University of New York (SUNY) at Albany, NY.

In the early 1990s, SUNY and the Department of Energy`s Pacific Northwest Laboratory jointly granted an exclusive license to YES to manufacture and sell the multifilter rotating shadowband (MFR) technology. Since then, YES has expanded this technology into the UV to provide the same high-quality measurements at narrowband wavelengths as offered by the UVB-1 in the broadband. Both the MFR and UVMFR join the UVB-1 as key instruments in the USDA`s UV-B monitoring network. The latest development from the SUNY partnership is a line of visible/NIR and UV shadowband spectroradiometers, which use innovative state-of-the-art optical CCD technology, challenging the standards in the field today.

With initial SBIR support from the USDA, in the mid 1990`s YES introduced the Total Sky Imager, the world`s first low cost commercial digital sky imaging system. The TSI is a fully automatic camera that permits airports and weather stations to fully automate the measurement of present weather sky conditions and cloud fraction, and to some extent visibility and cloud type.
