We design and manufacture quality meteorological instruments for scientists
YES was founded in the late 1980s by a team of scientists and engineers who combined their experience in theoretical physics, software, and precision analog electronics to tackle worldwide environmental challenges. 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. Today, YES provides a complete line of professional reference-grade optical water vapor instrumentation using the latest digital chilled mirror technologies and thermal stabilization. Most of our water vapor humidity instruments are microprocessor-managed and benefit from adaptive digital control loop technology. Many of our instruments are TCP/IP network-ready, for example, our Rotating Shadowband Spectroradiometers and Total Sky Imager systems are internet-ready, and data can be viewed by anyone with a web browser. Our goal is to market technology that reduces both the subjectivity and overall dependence on human labor for routine environmental observations, thereby increasing data quality and lowering the its customers' cost of daily operations. Measurement products cover surface and upper air weather parameters for solar radiation, air temperature, ambient dew point/humidity, barometric pressure, winds and precipitation, and eventually even space weather, covering "mud to sun." YES specialize in creative adaptation of these core sensing technologies to address customer's custom remote observation applications.
