Monthly lowest air temperatures for Australian Antarctic stations.
Listed in NASA Earthdata CMR
INDICATOR DEFINITION Monthly lowest temperatures obtained from observed daily minimum temperatures for Australian Antarctic stations Casey, Davis, Mawson and Macquarie Island.
Description
TYPE OF INDICATOR There are three types of indicators used in this report: 1.Describes the CONDITION of important elements of a system; 2.Show the extent of the major PRESSURES exerted on a system; 3.Determine RESPONSES to either condition or changes in the condition of a system.
This indicator is one of: CONDITION RATIONALE FOR INDICATOR SELECTION Global climate models show warming in response to increased greenhouse gas (carbon dioxide, methane etc) concentrations in the atmosphere; this is called the 'enhanced greenhouse effect'. Because of this, there is interest in observations of temperature across the globe, including Antarctica. Extensive high-quality observations from fixed locations are essential to serve as direct indicators of temperature changes and also confirm climate model output.

DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM Spatial Scale: Australian Antarctic stations: Casey (lat 66 degrees 16' 54.5" S, long 110 degrees 31' 39.4" E), Davis (lat 68 degrees 34' 35.8" S, long 77 degrees 58' 02.6" E), Mawson (lat 67 degrees 36' 09.7" S, long 62 degrees 52' 25.7" E) and Macquarie Island (lat 54 degrees 37' 59.9" S, long 158 degrees 52' 59.9" E). Temporal scale: Monthly. Measurement Technique: Thermometry.
RESEARCH ISSUES There is need to develop a high-quality data set from the available data, correcting erroneous data and estimating missing data. Adjustment may be necessary for changes in site location or exposure, and for changes in instrumentation or observing practices. Some of these changes are documented in the station history files held by the Regional Observations Section.
These history files are currently held as paper records, although more recent information is held electronically and there is an effort to digitise the older records. Before the data can be used for the detection of change, a concerted effort will need to be made to identify deficiencies in the data, and then make compensations where possible. This is made more difficult by the lack of suitable comparison sites.
