Summary
Abstract: Metadata record for data from ASAC Project 2386
See the link below for public details on this project.

---- Public Summary from Project ----
'Frozen dunes: An indicator of climate variability, McMurdo Dry Valleys, Antarctic'. This is a two year study involving scientists from Australia and New Zealand, which aims to use the internal structure of frozen sand dunes to identify climate change in the unique hyper-arid region of the McMurdo Dry Valleys.

This metadata record describes data collected from an automatic weather station (AWS) situated in the McMurdo Dry Valleys of Antarctica.

The download file contains an excel spreadsheet, which provides some general site information about the location of the AWS, as well as ten minute observations from the end of November 2004 to early December 2004.

The fields in this dataset are:

Date
Time
Pressure (mbar)
Wind Speed (m/s)
Gust Speed (m/s)
Temperature (degrees C)
Wind Direction (degrees)
Solar Radiation (W/m^2)
Dew Point (degrees C)
Relative Humidity (%)
