Coats Land AWS index

REFERENCES & NOTES

Full details can be found in:

Renfrew, I. A. and P. S. Anderson, 2002: The surface climatology of an ordinary katabatic wind regime in Coats Land, Antarctica, Tellus, 54A, 463-484.

However some notes on calibration etc, extracted directly from the paper have been reproduced in the file:

STATION METADATA

The AWS station details are:

location variable = [ 1 2 3 4 5];

location name = [C1 C2 C3 C4 Halley];

height = [43 400 1400 1650 37];

slope = [0.7 5.5 1.0 0.8 0.07];

latitude = [-75.88 -75.96 -76.70 -76.81 -75.60];

longitude = [-25.49 -25.41 -24.53 -23.50 -26.20];

distance from Halley (km) = [37 46 132 155 0];



ASCII DATA

The AWS + Halley data are stored as time series for each month and year here in file format clamp_yyyy_mm.asc (e.g. clamp_1996_01.asc is the first file)

The data are in ascii format with each column a variable. The variables are:

yyyy month day hour minute seconds location ...

windspeed winddirection pressure battery_voltage ...

t1 q1 rh1 rhi1 theta1 ...

t0 q0 rh0 rhi0 theta0 ...

dthetadz rho tau shfx lhfx ...

ppert cloud

The variable names are self explanatory. All variables are quality-controlled and calibrated as described in Renfrew and Anderson (2002). Note 1 indicates the upper sensor and 0 the lower sensor. See Renfrew and Anderson(2002) for a description of how the surface turbulent fluxes and the perturbation pressure are calculated. Note the cloud variable is only filled in at Halley. The location variable (1 to 5) represents the location: 1 = C1, 2 = C2, 3 = C3, 4 = C4, 5 = Halley



MATLAB DATA

I have done much of the data processing and visualisation in Matlab. If you like you can download the entire 8-year data set (in two files) from here. The first file clamp_aws.mat contains 1996 to 2000, the second file clamp_pico.mat contains 2001 to 2003.

There is some simple code to read and plot time series in here. There is much more code and if you're really keen contact me and I can probably let you have a copy, although I can't attest to the programming quality!
