more information on pricing and delivery times.
 
May 2005: Navy Deployable Micro Weather Station R&D
YES has received a Phase II SBIR R&D contract
from Navy Space and Naval Warfare Systems command to develop and
advanced Deployable Micro Weather Sensor (DuWS). This low cost
technology will assist forward area deployments and special operations
forces by making quick on the spot measurements of the environment,
including the winds above the treetops without the need to erect a
meteorological wind tower. Ultimately, a version of the DuWS package
will be air-deployable and use satellite communications to gather
weather data inside hostile territory without endangering lives.
April 2005: Valparaiso University takes delivery of ARL-9000 and TSI-880
Systems
YES has installed a Model ARL-9000 and TSI-880 at Valparaiso
University in Indiana. The school has recently built a brand new
weather center for its Geography
and Meteorological Departments that rivals most educational and even
research institutions in the world today. In combination with its Communications
Department, Valpo now offers its students a powerful degree combination.
Next year, Eventually, a Doppler Weather Radar will compliment the cloud and upper
air measurements that the YES Model TSI-880 and ARL-9000 provide to the
students and faculty.
April 2005: USAF Space Weather Imager R&D
The Air Force Research Laboratory has awarded YES with
a Phase II SBIR R&D Contract to develop an advanced low light night
sky imager (SWXI) for characterizing space weather events. Space weather
geomagnetic storm activity can interfere with and reduce the accuracy of
GPS signals, which are used to guide both troops and ordinance. During
conflict, commanders need to know and understand the impact of these
storms on their worldwide communications, command and control equipment.
System software will ultimately have the capability to ingest data from
multiple SWXI cameras to establish both height and trajectory
information, and will help to ground truth the upcoming Air Force CNOFs
satellite mission. The hardware will resembled the TSI-880 but extend it
to all weather, night operation.
October 2004: New Model DPH-2012 Fuel Cell Hygrometer Makes Humidity Measurements in
Real Time
An industry first, YES has
begun shipping its high temperature fuel cell dew point hygrometer, the Model
DPH-2012. It is the first commercial system capable of making real time
high temperature dew point measurements within hydrogen fuel cells at or
near steam point. YES
engineers initially developed the digital instrument for a large plastics firm but
then adapted it for a major US automotive manufacturer conducting fuel
cell research. The high temperature humidity sensor will provide
researchers working on fuel cells with an important analytical tool for
diagnosing fuel cell performance.
June 2004: DOE awards YES and Umass Micro Power Plant R&D Grant
The US Department of Energy awarded YES and the
University of Massachusetts at Amherst Engineering department a Phase I
SBIR grant to develop a power scavenging technology to power future
wireless sensor technologies. Working together, the two teams will
prototype and ultimately design a modular product that can address a
wide number of applications. GE, Honeywell and Eaton are also involved
with the program as industrial partners.
July 2004: TMS-7200 Weather Web deployed for Democratic National
Convention in Boston
In the summer of 2004 YES was contracted to deploy
its first metropolitan area Weather Web in and around the city of Boston to make real time
wind measurements for the Democratic National Conventions. A fleet of
strategically located wireless sensors feed continuous information to a
Transport and Dispersion (T&D) plume dispersion model that can be
used by first responders in the event of an emergency. This is the first
system of its kind, and is a commercialization of technology funded
initially by the US Army and Navy SBIR programs.
November 2003: TPS-3100 Hotplate Precipitation Sensors Introduced
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 Hotplate
News Announcement or the Data Sheet.

as advanced Langley processing. Contact YES sales or your local
sales representative for pricing.
January
2003: Low-cost Thermo-hygrometer
Continuing with our reputation for high precision met instruments, the
Model PTU-2000 thermo-hygrometer provides an economical alternative
to chilled mirror hygrometer technology. The sensor features a digital
serial output with aspiration with a double-shielded thermometer and polymer capacitance hygrometer sensor,
and an optional solid state pressure sensor.
October

Version 1.4 Released
The latest release of YESDAQ, an database for managing data
collected from YES instruments and other meteorological instruments, is
available. Version 1.4 includes a World View feature, which lets you
click on a site location (indicated by a plus sign on the world map) and
quickly display the data from that site. A Current Day field lets you
view today’s data without filling in specific date information. This
release also supports Vaisala ceilometers,
enabling you to import and display ceilometer data.
June
2000: Rotating Shadowband Spectroradiometer
The visible/NIR RSS and
ultraviolet UVRSS are fully
automatic spectroradiometers for field measurement of direct, diffuse
and total global atmospheric spectral irradiance. The innovative optical
design principle employs prisms along with ultra reliable
state-of-the-art solid state charge-coupled device (CCD) technology to
produce a highly stable instrument with almost no moving parts. Until
now, most spectroradiometers have used diffraction, via ruled optical
gratings to select wavelengths. The gratings are moved using complex
mechanical motor drives, which take several minutes to complete a scan,
during which time the sky conditions may change dramatically. Both the
RSS and UVRSS use refraction, via a locked down prism that images the
spectrum onto a solid-state linear detector array. In both versions, the
detector is an advanced cooled CCD detector similar to one used in the
Hubble telescope. The UVRSS has a
third optical stage that permits operation in
the UV-B down to about 295 nm. Compared with other monochromator-based
spectroradiometers that suffer from stray light rejection in the far UV-B, the UVRSS represents a major advancement in
the state-of-the-art in UV-B radiometry, in terms of long term
radiometric stability and wavelength accuracy. In addition, the RSS and
UVRSS employ a rotating shadowband that allows simultaneous
direct-normal, diffuse, and total measurements over the entire spectral
range.
May
2000: YESDAQ
1.0 Software Available
YESDAQ Software acts as a central
data repository and data collection engine. Built upon open source mySQL
database technology, YESDAQ collects data from MFR, TSI and RSS systems
and permits reprocessing of cloud image data collected by the TSI. YESDAQ
also supports ODBC/JDBC
connectivity to allow users to perform calculations in their favorite MS-Windows/third-party
application.
April
2000: YES Delivers TSI-880 to Major US Government Agencies
The new Model TSI-880 Automated Total Sky Imager
represents the next
generation in automated environmental imaging and observation systems.
It features a high availability image processing system that can
interface with existing weather observation systems such as ASOS. It
also provides present weather monitoring and animations to users with web
browsers via the Internet. Processing is done on board the TSI-880 so
Internet users can browse both raw and processed data with no host
software required on their local PC.
YES recently delivered TSI-880 systems to three different major US
federal government customers:
- US Navy (SPAWAR)
- Federal Aviation Administration
- US Department of Energy (Atmospheric Radiation Measurement
Program)
The DOE's TSI-880 system was installed at the Southern Great Plains
site run by the Atmospheric Radiation Measurement
program. The TSI-880, along with
the YES' new infrared instruments, the TIR-570
and TSI-880, took part in the spring 2000
Cloud
Intensive Observation Period. The Navy and FAA are each evaluating
the TSI-880's unique capabilities within their operational ASOS
networks. The TSI was the commercial result of a USDA-sponsored
SBIR Phase II R&D program.
March
2000: New
Infrared Radiometers
The new Models TIR-550 and TIR-570
extend the YES radiometry line into the infrared with two performance
points. Traditionally, pyrgeometer instruments have
been used to measure long wave (thermal infrared from 3-50 microns) broadband
radiation
via a thermopile covered by a visible/NIR optical filter. A major
problem with thermopile-based instruments is their unit-to-unit
variation even after fresh calibrations.
In the Total Infrared Radiometer Model
TIR-550 (a direct result of a NSF-funded SBIR phase II R&D
program), YES has incorporated a unique compensation measurement
system in addition to improved optical coatings to improve the
unit-to-unit calibration agreement between instruments. It represents a new standard in low cost broadband IR field
radiometry and comes standard with aspiration.
The more sophisticated Model TIR-570
features a highly sensitive, ultra wide spectral response chopped pyroelectric detector.
It contains an integral self-calibration
blackbody reference as well as a shadowband to help keep the intense
direct normal visible solar radiation form self-heating the instrument. It is the first instrument ever to provide
measurement accuracy of 1%, surpassing all other field radiometers in the
infrared range. In addition to global warming research, the TIR-570 has
applications in providing ground truth data to support satellite
calibrations. It is the result of a past DOE phase II SBIR R&D
program.
Together, these instruments extend our MFR family of visible/NIR instruments into
the thermal infrared portion of the spectrum giving you one, unified
supplier from the UV-B through the long wave thermal infrared.
February
2000: YES Expands its Humidity Line
The new MET-2010 Meteorological Thermohygrometer represents the
state-of-the-art in the outdoor measurement of ambient air temperature and dew
point humidity via chilled mirror technology. It has a conservatively rated temperature
accuracy of ±0.02°C over a ±50°C range. Like the TSI family, the
microprocessor-based MET-2010 is the result of an intensive multi-year
R&D effort, originally funded by a USDA Phase II SBIR program.
January
2000: YESDAS
Manager Software Released
Extending its MFR-7, UVMFR-7 and YESDAS-2 data acquisition product
lines, YESDAS Manager V 2.0 software
now supports these radiometers under Windows 9x/NT. Capable of
supporting both individual systems and entire networks, it features:
- A polling engine for automated data collection
- A calibration editor that enables users to edit and create
programs to produce data in a desired format
- A web server user interface for publishing collected data to other
users via the Internet
October
1998: TSP-700/A Aircraft Pyranometer
The TSP-700/A is the first total solar pyranometer specifically
designed for aircraft applications. It uses the advanced measurement
technology of the TSP-700 in a
housing designed for flight use. No ventilation or heating is required
since the instrument is cooled by normal airflow. Currently, the
TSP-700/A instrument is being flown by the Royal Meteorological Service
in Great Britain.
October
1997: Precision Virtual
Hygrometer PVH-2020
The PVH-2020 expands the YES
instrument line into humidity measurement. The founders of YES have
extensive experience in the field of hygrometry, dating back 40 years to
when YES founder David J. Beaubien and YES scientist Arthur Bisberg
designed and built the first dew point hygrometers at the former
Cambridge Systems, Inc. (later acquired by EG&G and now EdgeTech). Today, YES engineers
have applied new optical and microprocessor technologies to the basic chilled-mirror technique
for water vapor measurement used in older humidity instruments to develop the
next generation of dew point hygrometers.
May
1996: Dual Head MFR (DMFR-7)
We have adapted our DMFR-7
instrument to incorporate a second, downward looking radiometer head to
provide simultaneous measurement of both upwelling (radiation from the
ground) as well as downwelling (radiation from the sky) direct, diffuse
and global spectral irradiance. The DMFR-7 permits automated measurements
of albedo. Dr. Kathy Moore of ASRC is
using the DFR-7 at Harvard Forest near YES to study the effect of
climate change on the forest.
