October 2003: NCAR Selects Yankee Environmental Systems as the exclusive manufacturer of the Hotplate

Yankee has been awarded a manufacturing license for hotplate precipitation gauge technology originally developed and patented by The National Center for Atmospheric Research of Boulder, CO and the Desert Research Institute of Reno, NV. This rugged meteorological sensor can measure precipitation rates in real time with no moving parts. It works by electronically maintaining the temperature of two back-to-back round plates at a constant temperature above ambient and measuring the difference of the power required to hold them at this temperature. Falling precipitation cools the upward facing plate more, while wind cools both plates evenly

Important applications include surface precipitation meteorology and deicing operations that require knowledge of the thermodynamic state of current atmospheric wet precipitation. YES has begun accepting orders for its Model TPS-3100 Total Precipitation Sensor while verification testing in NCAR wind tunnels continues in parallel.  Browse the YES Hotplate Product Announcement or the Data Sheet.

April 2001: U.S. Department of Energy deems TSI-880 a "Standard ARM Instrument"

At its spring science team meeting, DOE researchers officially made the TSI-880 a standard ARM instrument. This means DOE will budget for maintenance and support of the TSI-880 into the future. What is politically significant here is that the TSI had to first demonstrate it could augment the far more expensive Whole Sky Imagers that ARM owns. It did this throughout 2000 by demonstrating excellent up time and reliability.

In addition to the TSI-880 operating at the CART site, the DOE has three additional YES TSI-880 sky imagers for its other Atmospheric Radiation Measurement (ARM) sites in the Tropical Western Pacific and North Slope of Alaska. YES has a long association with supporting ARM science goals - for more information about ARM, visit www.arm.gov.

March 2001: Massachusetts Technology Collaborative selects YES for SBIR Commercialization Success Award

Based on its commercial success with the Total Sky Imager family, under a competitive selection process MTC singled YES out from many other Massachusetts high tech companies for this SBIR award. The TSI family grew out of a 1996 USDA SBIR program grant. The TSI has been adopted by several US government and international agencies. In the US, the FAA, NOAA, US Navy and DOE have each ordered TSI-880's for various applications. Over the past decade YES has received four Phase II awards from the USDA. The company's highly successful UVMFR-7 instrument also grew out of one of these programs and now forms the cornerstone of the US governments' UV-B Monitoring program

February 2001: YES Wins ARL Meteorology SBIR

The DoD has awarded YES a Phase I SBIR R&D program to develop an advanced networked meteorological system for the US Armed Services. This technology will help modernize surface observations by utilizing the internet as a mechanism to move data. In the 1960's, while at Cambridge Systems Inc. (now Edgetech) founders of YES designed the TMQ/22 Tactical Measuring set for the US Army. The TMQ/22 and other later TMQ systems have been used for many years. YES is working in cooperation with researchers at White Sands Missile Range and Virginia Tech on this project.

January 2001: YES Presents Five Papers at the AMS Annual Meeting

In addition to showing off its new booth, YES engineers presented five instrumentation papers at the 81st annual meeting of the American Meteorological Society in Albuquerque, New Mexico in January 2001. The topics of the papers represented current research programs underway at YES:

  • Comparison of Two Imager-Based Methods for Determination of Winds Aloft
  • A Pyroelectric Detector-Based Nulling Infrared Radiometer
  • An Isothermal Pyranometer Incorporating Detection and Elimination of Error Due to Dome Radiation
  • Flight Test Results of a Low-Cost Balloon-Borne Chilled Mirror Hygrometer
  • A New Fiber Optic-Based Approach to Meteorological Instrumentation

The first three were also talks at the meeting (order "11th Meteorological Observations" proceedings from AMS).

Come visit YES at booth #108 at next year's 2002 AMS meeting.

October 2000: U.S. Department of Energy orders RSS-1024 and additional TSI-880s for ARM Sites

After several years of testing prototype versions of the visible rotating shadowband spectroradiometer (RSS), developed jointly by YES engineers and scientists at the Atmospheric Sciences Research Center (ASRC) in Albany, New York, the U.S. DOE has ordered a commercial RSS-1024 for its Southern Great Plains Clouds and Radiation Testbed site in northeastern Oklahoma.

In addition to the TSI-880 operating at the CART site, the DOE has also ordered three additional YES TSI-880 sky imagers for its other Atmospheric Radiation Measurement (ARM) sites in the Tropical Western Pacific and North Slope of Alaska. YES has a long association with supporting ARM science goals - for more information about ARM, visit www.arm.gov.

October 2000: New Winds Aloft Algorithms for TSI-880

An ongoing experiment at the Atmospheric Sciences Research Center/National Weather Service office in Albany, New York is attempting to derive winds aloft using YES Total Sky Imagers. YES has installed two TSI-880s: one co-located with a Vaisala Model CT25K ceilometer (owned by ASRC); the second TSI-880 a mile away. All three instruments are networked to a central YESDAQ database. Click on yesdaq2.asrc.cestm.albany.edu for data collected by these instruments. By comparing images from the two TSI-880s located a mile apart, YES engineers are working on algorithms to derive winds aloft or wind speed. YES is comparing the results of using two TSI-880s versus one TSI-880 with ASRC's ceilometer. YES is also trying to calculate cloud height using two TSI-880s, a much more difficult task. YES presented a paper at the 81st annual meeting of the American Meteorological Society in Albuquerque, New Mexico in January 2001 (see below). 

October 2000: YES Demonstrates TSI-880 and MET-2010 at Several Meetings This Fall

YES engineers have attended several meetings this fall to demonstrate the companyís latest products: the Total Sky Imager Model TSI-880 and the Meteorological Thermohygrometer Model MET-2010. Some of the meetings included the National Weather Service, Air and Waste Management, and the Nuclear Meteorological Userís Group. If you didnít get a chance to see us at one of these meetings, look for us at the 81st annual meeting of the American Meteorological Society in Albuquerque, New Mexico in January 2001, Booth #940.

May 2000: YES Wins Ship Meteorology SBIR

NOAA has awarded a Phase I SBIR R&D award to YES to develop shipboard weather sensor systems. This technology will modernize the "volunteer observations from ships" (VOS) program that gathers critically needed weather data from merchant marine vessels. YES is working in cooperation with researchers at Woods Hole observatory on this project.

May 2000: YES Wins Acid Rain SBIR

NOAA has awarded a Phase I SBIR R&D award to YES to improve precipitation collection systems for monitoring acid rain. The US government has been collecting rain water from nearly 200 sites across the country as part of its multi-agency acid rain monitoring program, the National Acid Deposition Program (NADP). For the past 25 years, NADP has not updated their rainwater collection systems. This SBIR involves designing new collection systems that can potentially be scalable to handle multiple vessels in support of new studies on mercury. YES is working with scientists at Colorado State University/Fort Collins' Natural Resource Ecology Laboratory and also researchers at Penn State University on this project. 

April 2000: YES Wins Fiber Met Sensor SBIR 

The US Navy has awarded a Phase I SBIR R&D award to YES to develop all-optical meteorological weather sensors, in partnership with Virginia Tech's Fiber Electro Optical Research Center (FEROC). The US Navy has awarded YES a six month $70,000 R&D SBIR contract to develop fiberoptic meteorological sensors that can potentially measure winds, temperature, pressure and humidity. The US  Navy is particularly interested in the fiber optic sensor technology because it potentially eliminates corrosion, EMI, and EMP problems that warships must endure. 

November 1998: Spain chooses YES UVB-1 for its UV monitoring network

After a very competitive selection process, the Spain has selected YES broadband pyranometers for its country-wide UV monitoring program.
