Description

Ice Stations 1-4
Two Davis weather stations are placed either side of a sea-ice ridge. The closest station to the ship is called 'unit 1', and the further station is 'unit 2'.
Each weather station includes an anemometer at 2m, temperature/humidity sensor at 1.6m and solar sensor at 1m.

Ice Station 6-8
For the last three stations we assembled the two weather stations onto one mast. This is so we can look at wind profiles and hopefully gain some understanding of wind shear and drag on the ice. Anemometers were set 1m apart at 1m and 2m heights. Temperature/humidity sensors were also set 1m apart. Only one solar sensor was used, at the same height as previous deployments.


Additional data information : metadata record 201213001
For convenience, and easy loading of the data into any data processing software, the .csv where pre-processed and variables where stored into new ascii files without extensions. Each ascii file corresponds to a given station and a given mast unit. There are 20 columns, separated by tabs.
Content of the files:
Column 1 : Day of year []
Column 2 to 7 : Date [YYYY MM DD hh mm ss]
Column 8 : Barometric Pressure [hPa]
Column 9 : Outside Temperature [C]
Column 10 : High Outside Temperature [C]
Column 11 : Low Outside Temperature [C]
Column 12 : Outside Humidity [%]
Column 13 : Dew Point [C]
Column 14 : Wind Speed [m/s]
Column 15 : High Wind Speed [m/s]
Column 16 : Low Wind Speed [m/s]
Column 17 : High Wind Direction [degrees with respect to North,
e.g. East = 90, South = 180, etc...]
Column 18 : Dominant Wind Direction [degrees with respect to North,
e.g. East = 90, South = 180, etc...]
Column 19 : Solar Radiation [W/m^2]
Column 20 : High Solar Radiation [W/m^2]

Quality

We had technical issues with data download that resulted in no data being collected for ice station 3. Wind directions were only stored as quadrants, as the Davis ENVOY-8 data logger cannot programmed to archive wind direction in degrees.
