The dataset contains two hyperspectral images, each 3260 by 1004 pixels with 162 spectral bands, acquired on January 10 and 30, 2013. Data were collected and processed by AU_AADC researchers to estimate moss chlorophyll content and leaf density.
The AST3-1 Point Source Catalogue contains stellar photometry data from the Antarctic Survey Telescope AST3-1 at Kunlun Station, Dome A. AST3-1, the largest optical telescope in Antarctica at deployment, operated from March to May 2012, surveying nearly 2,000 square degrees and capturing thousands of exposures. The data were processed by the Antarctic Astronomy Group at NAOC and released in a 2018 peer-reviewed paper.
NCAR global, 2-hourly GPS precipitable water data are derived from ground-based GPS measurements of zenith path delay. The dataset combines measurements from the International GNSS Service (since 1995), U.S. SuomiNet (since 2002), and the Japanese GEONET network (approximately 1100 stations from 1997 to 2005). The data are provided by SCIOPS, with the last known update in December 2012.
2012 data from the SIPEX II Antarctic voyage contains albedo measurements for thin sea ice covered with frost flowers, nilas, snow, and slush across the 300-2500 nm wavelength range. The Australian Antarctic Data Centre collected the data using an Analytical Spectral Device spectrophotometer, recording 5 upwelling and 5 downwelling spectral signatures per site. Processed spectra are used to calculate albedo by computing the ratio of upwelling to downwelling radiation.
Cosmic ray observations from the McMurdo neutron monitor, a key southern station in the 12-station 'Spaceship Earth' array. The dataset supports research into solar energetic particles and galactic cosmic ray modulation, with observations targeted through the solar maximum predicted for 2011-2012. Data was contributed by the AMD_USAPDC organization.
15 spectral bands of Top of Atmosphere radiance data were captured by the Envisat satellite's MERIS instrument operating continuously on its descending orbit track.
