All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

This dataset contains images of the infrared emissions from the Meinel band from the night sky above Davis, Antarctica.

The camera runs continuously during darkness, over intervals set by a yearly almanac of start and stop times. Images of resolution 320x256 pixels are collected and stored approximately every ten seconds. They record the emission intensity over much of the sky.

Continuous daylight through summer limits the observation interval to between February and October.

The camera was first installed in the summer of 2011/12 and started operation 2012.

Purpose

Analysis of the image data yields parameters describing gravity waves and other disturbances to the hydroxyl emission layer, centred near 87 km.

Project History:
The operation of the Davis USU camera has supported a number of Antarctic Science Research projects. These include:
Project 4025 – ‘Gravity wave drag parameterization in climate models’. 2012/13 to 2016/17
Project 4065 – ‘Antarctic Gravity Wave Imaging Network (ANGWIN) for Collaborative Mesospheric Research’. 2012/13 to 2016/17
Project 4445 – ‘High-latitude gravity wave processes and their parameterization in climate models’ 2017/18 to 2020/21
Further details of the outcomes of these projects can be found on the Antarctic Division website www.aad.gov.au.

Quality

Data quality varies according to the amount of cloud present. Infrared emissions from the Hydroxyl layer are strong and clear skies provide high signal to noise images.

Abrasion of the dome above the camera by grit or snow blasting in strong winds can adversely affect the camera’s view of the sky. The dome was replaced for this reason on Aug 20 2017.

An updated dataset including 2018 data was provided in 2019. The dataset from 2012-2017 is referenced by the doi: 10.26179/5c3bbcde1a696

Access

These data are publicly available. However, owing to their size, they will be placed on a cloud service on request.
