Project: Study into spider behaviour in the wind (flying spiders!)Location: UK
|
Two USA-1 anemometers were used to study
spider behaviour in the wind to discover how spiders are able to 'fly' or 'parachute' into
new territory on single strands of silk. One of the anemometers was mounted at
ground level and the other 1 metre apart at 1 metre above ground level (please see
diagram):

Project: Weybourne Atmospheric Observatory (WAO) Location: North Norfolk Coast, East
Anglia, UK
|
Data from the Metek USA-1 at the Weybourne
Atmospheric Observatory is uploaded to the WAO site frequently throughout each day. To see
their latest sonic anemometer data please visit http://weybourne.webapp1.uea.ac.uk/sonic.html
To see the graphical representations of the
data for each day click on the dates listed on their website.
These graphical representations include a wind
rose and graphs of the following:
Temperature
Vertical Heat Flux
Vertical Momentum Flux
Wind Velocity
Mean Vertical Wind Component
Wind Direction
In addition maximum, minimum and mean data for
each month is also represented graphically (click on the months you are interested in).

Project: Measuring turbulent flows over a forested hillLocation: Isle of Arran off the south
west coast of Scotland
|
| A field
campaign to provide data for validating models and theories on the problem of canopy air
flow interaction over complex terrain was conducted on the Isle of Arran.

Project: CLACE 4Location: Jungfraujoch in the Swiss Alps
|
|
The CLACE 4 project (Cloud and Aerosol
Characterisation Experiment in the Free Troposphere), held during the wintertime at the
Jungfraujoch High Alpine Research Station, studies the interaction of aerosol particles
with ice clouds. A Metek heated ultrasonic anemometer is used for 3D wind speed and
direction as well as sonic temperature.
(A Biral HSS Present Weather Sensor is also
used to detect the presence of cloud and precipitation - see HSS references for more
info).

Project: Shoeburyness 2006 Field TrialLocation: Shoeburyness, UK
|
| The Metek
USA-1 was used in this project to assess innovative correlation techniques for the study
of meteorological and topographical effects on sound propagation by using advanced signal
design techniques in conjunction with digital signal processing methods.

Project: ARTIST (Arctic Radiation and Turbulence Interaction Study)Location: Kongsfjorden |
|
As part of this study the Metek USA-1 was used to measure
turbulence and heat fluxes. The instrument was aligned northward with a precision of 15
degrees at a height of 3.35 meters above ground level. Other instruments at the
radiometric station near to Kongsfjorden included a hygrometer, radiometer and 3 x
thermocouples.

Research: Halley Research StationLocation: Antarctic |
| Details:
USA-1 ultrasonic anemometers are used at the Halley
Research Station for turbulence measurements.
The USA-1 ultrasonic anemometers are mounted at 4m, 15m and
30m heights sampling at 40Hz and recording continuously at 10 Hz. There are also 2 USA-1
Sonics at 10 m on remote masts.

Project: Aviation Weather Research Program (AWRP)Location: BNL/NCAR Ceiling & Visibility site, Long
Island, USA |
| As part of the Aviation
Weather Research Program (AWRP) (which won FAAs Excellence in Aviation
Award, and the National Weather Association's 2002 Aviation Meteorology Award.
) the Fog Physics and Prediction project is aimed at better understanding the processes determining the
life cycle and variability of low visibility (fog) events.
The Ceiling and Visibility site on Long Island is
one of the observational sites for characterisation of fog and low visibility environments
and is equipped with a 90 m tower which has 7 levels of temperature, humidity and wind
sensors including two Metek USA-1 sensors mounted at 32 m and 70 m. (Three Biral
visibility and present weather sensors are also mounted at 4 m, 32 m and 70 m).

Project: Carbon Balance of Peatlands at Moor HouseLocation: Upper Teesdale National Nature Reserve, UK |
| A study to
quantify the carbon balance of a typical UK upland peat catchment area will measure all
components of the carbon budget, including atmospheric and fluvial fluxes. The three
components of windspeed are measured at 20 Hz by a Metek USA-1 ultrasonic anemometer
mounted at a height of 1.75 m at the eddy covariance measurement site.
