Sonic anemometer measurements on an ice floe on the Weddell Sea, 11/2004-01/2005
Entry ID: FIMR_ISPOL_SONIC_ANEMOMETERS


Summary
Abstract: As a part of the international expedition Ice Station Polarstern (ISPOL,
http://www.ispol.de/), sonic anemometer measurements were carried out on ice
floes on the Weddell Sea (68 degrees S, 55 degrees W) in 28.11.2004 - 2.1.2005.
Two Metek USA-1 sonic anemometers were used, set up on top of 3.5-m high steel
masts.

The instrument were set up in two different locations on the single large ISPOL
ice floe. For a short period, one of them was also set up on a separate floe.
Three wind components and air temperature were sampled at 20 Hz frequency. From
these data, momentum and sensible heat fluxes and other turbulence parameters
were automatically calculated at 10 minute intervals. The data set includes the
raw (20 Hz) air velocity and temperature data, and the following parameters as
10-minute averages: wind velocity (m/s), air temperature (degrees C), variances
and covariances of the wind/temperature components, friction velocity, drag
coefficient, Monin-Obukhov length and sensible heat flux. The air temperatures
are just trendsetting, relative readings.
