Long Term Observations and Modelling of the Stable Antarctic Boundary Layer of the Ross Ice Shelf

This work is an extension of the last year event; K352A carried out
during a one-week period in the summer season of the years 2000-2001
and 2001-2002. Along term data would be collected for one complete
year starting in the summer season 2002-2003.

Our General aims are
Gravity Waves in Antarctica
Turbulence study in the Stable boundary layer of Antarctica

Installation of
Three Automatic Weather Stations (AWS)
Surface energy and turbulence measurements tower

A three Automatic Weather Stations (AWS) were installed on the Ross
Ice Shelf, near the Scott-Base, Antarctica. To collect data on
turbulence, a meteorological mast was installed near the wet-Lab,
Scott-Base.

A data collection of atmospheric turbulence is being carried out
with two sonic anemometers, while the surface energy balance is being
measured using a KippZonen net radiometer. Three AWS with sensitive
digiquartz barometer each were also set up in a triangular array to
measure the surface wind, relative humidity, temperature and pressure.
The AWS plus the barometer were also used to detect the passage of
gravity waves, which is also a component of the study.

The surface observations would be completed with air observations,
taken from two radiosonde ascents at 00 UTC and 12 UTC released from
McMurdo station located about 2km from the site.
