Abstract:
Automatic data loggers are often used to monitor environmental variables such as temperature (of air and soil), humidity, wind speed and radiation in microclimates where experimental or ecological studies are being carried out. Some loggers are only in operation for a few weeks or months while others have been run for several years. Loggers have been sited in a wide variety of locations from the sub-Antarctic (South Georgia), South Orkney Islands (Signy) various Peninsula sites (as far south as Alexander Island - 70S), and some continental localities (e.g. Victoria Land). These form an important data resource to the climate conditions experienced by Antarctic terrestrial organisms.
Various types of logger are used. Sensors tend to be deployed at or near ground level and in and around particular types of vegetation, or other experimental sites, such as cloches. Loggers used include Grant, Delta-T, Campbell and Squirrels.
Victoria Land data for Kay Island and Edmonson Point in 1995 and 1996 was collected under the BIOTEX 1 experiment of the SCAR BIOTAS (Biological Investigations of Terrestrial Antarctic Systems) Programme. An overview of BIOTEX is available as a PDF file.

| Quality: | Various - internally documented. | |
| Lineage: | All micrometeorological data have been converted to Oracle format and are held in a database that is maintained by the PDC at BAS. However some raw data are held in additional files of various formats. Data were outputted as binary files of numbers; see equipment documentation to understand the output files (different equipment/loggers were used at different locations). Log books and documentation on sensor locations are available from the Biological Sciences Division. The quality of the data varies, however quality status is internally documented within the dataset. Some data was listed as being raw data logged during a period when the instrument functioned correctly but having undergone no processing. |
