Yankee Environmental Systems, Inc.

YES is committed to building a leadership position in the advanced environmental sensing. How has a small company developed so many new innovative products? Over the past decade, YES engineers have teamed with several world class research universities, including:

Virginia Tech

The State University of New York at Albany

The University of Massachusetts at Amherst

... as well as major national laboratories including:

DOE Pacific Northwest National Laboratory

Air Force Research Laboratory's Sensors Directorate

National Center for Atmospheric Research

DOE Savannah River National Laboratory

Office of Naval Research

YES has worked with these organizations on both R&D technology development programs and product licensing arrangements.

Since 1989, Yankee engineers have been focused on solving some of the most difficult measuring problems known to man, including global warming, acid rain, and ozone depletion. Our instrumentation products help solve some of your most difficult challenges in temperature and moisture, atmospheric radiation and remote automated weather observation. More recently, Yankee has focused its efforts on operational meteorology and homeland defense, such as tracking winds that might carry a plume from a dirty bomb. Automated Total Sky Imagers and Radiosonde Launchers reduce or eliminate the need for human observers, freeing personnel to work on more value-added tasks. Yankee introduced the world's first no-moving-parts precipitation sensor based on hotplate technology licensed from the National Center for Atmospheric Research. This novel sensor will lead to important improvements in air and road safety in winter conditions.

Yankee is an engineering and customer-driven organization, and this fact shows in its innovative environmental sensors, known for their high-quality and long term stability. Unique internet-enabled data collection and storage approaches used in the line of Automated Radiosonde Launchers, Rotating Shadowband Spectroradiometers and Total Sky Imagers represents the future of remote weather observation systems. State-of-the-art detectors, electronics, temperature-stabilization, and rugged mechanical packaging helps ensure accurate long term operation. A long term investment in extensive automated calibration laboratories has resulted in a suite of advanced NIST-traceable facilities supporting the characterization of sensors.

YES optical humidity and water vapor instruments are used in a wide range of process control and industrial dew point measurement. Our radiometers are used extensively on aerosol and ozone research, as well as air pollution studies.
