Six satellites from the COSMIC/FORMOSAT-3 constellation, launched in 2006, provide this annual average climatology of planetary boundary layer height. The dataset is derived from GPS radio occultation measurements, using an algorithm that identifies the height of minimum vertical refractivity gradient. Produced by the GES DISC, this collection represents the latest version as of its last update in 2019.
Cosmic ray measurements are provided with 1-minute and 1-hour time resolution from two mini-neutron monitors at Dome C. The dataset includes raw count rates, barometric pressure, voltage readings, indoor temperature, and pressure-corrected count rates. It was collected by SCIOPS and last updated in 2019.
Laboratory experiments from ENVIDAT present data on phase change at the surface of sodium chloride-water mixtures. The dataset includes near-edge X-ray absorption fine structure (NEXAFS) spectra of hydrohalite, collected between 259 K and 240 K. The data was published via NASA Earthdata and last updated in 2020.
Spectrum intensity data for gaseous halogen compounds was collected from 9 December 2018 to 12 June 2019 at King Sejong Station. Measurements were made using Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) by the AMD_KOPRI organization. The dataset captures atmospheric monitoring over a six-month period in the Antarctic.
Macquarie Ridge Complex Basalt Thin Section Images contain plane-polarized and cross-polarized microscope images of basalt samples. The collection includes samples from Macquarie Island and dredge samples collected during the TAN0803 voyage in 2008. Thin sections were prepared by Spectrum Petrographics and imaged using a Zeiss Axio microscope at Curtin University.
MAX-DOAS spectra and auxiliary sensor data collected aboard the Aurora Australis in the Southern Ocean. The dataset includes daily spectral files, log files with geometric and temperature data, accelerometer readings, and contextual images. It was produced by the AU_AADC organization and last updated in March 2019.
Cometa is a repository of multi-label datasets created by fdavidcl and last updated in March 2019. It provides a centralized archive for machine learning researchers focusing on multi-label classification problems.
Brewer Ozone Spectrophotometer measurements capture total ozone column density by analyzing light absorption between 286.5 nm and 363 nm wavelengths. AMD_KOPRI collected this data for monitoring meteorological variable changes at the Jang Bogo Station in Antarctica. The dataset's final recorded observations are from September 30, 2018.
Cosmic ray origin neutron count data was measured by a neutron monitor at the Jang Bogo Station in Antarctica. The dataset was collected by AMD_KOPRI and last updated in September 2018. It supports the study of neutron count variation in the southern high latitude region.
Data from a 2014/15 mesocosm experiment at Davis Station, Antarctica, examines the impact of elevated CO2 levels on diatom silicification. The Australian Antarctic Data Centre collected measurements including bulk and species-specific silicification, cell volume, and photosynthetic efficiency (Fv/Fm) from a natural Prydz Bay microbial community. Experiments simulated CO2 concentrations from 343 to 1641 micro-atmospheres to project conditions up to the year 2200.
Solar scattered light spectra and associated Euler angle measurements were collected using a MAX-DOAS instrument aboard the research vessel Aurora Australis during the 2017-18 season. The dataset includes daily binary spectrum files, log files with geometric and location data, and accelerometer readings for pitch, roll, and yaw. Data collection was managed by the Australian Antarctic Data Centre (AU_AADC).
BICEP2 and SPUD data originates from a four-year program upgrading the BICEP telescope at the South Pole to search for primordial gravitational waves via cosmic microwave background polarization. The project was a collaboration between the California Institute of Technology and the University of Chicago, with data collection spanning from 2006 through upgrades in 2009 and 2010. The dataset was last updated in the NASA Earthdata system in September 2017.
Antarctic cosmic ray neutron count data was collected in 2017 from a neutron monitor at the Jang Bogo Station. The dataset captures variations in neutron flux at a high southern latitude. It was provided by the organization AMD_KOPRI.
16x16 pixel infrared images sampled every minute from a scanning radiometer at Davis station, Antarctica. The instrument, developed at the University of Western Ontario, captures hydroxyl airglow variations in a 24x24 km region of the night sky at approximately 87km altitude. Observations were made in all cloud conditions between civil twilight each year from 1999 to 2016.
Distribution data for Stellaria media (common chickweed) on Macquarie Island includes plant locations, size measurements, and environmental factors from 8 major population sites. The dataset contains 8 files with waypoints, density maps, detailed plant metrics, and site summaries collected over 3 seasons. It was published by the Australian Antarctic Data Centre (AU_AADC) and last updated in March 2016.
Macquarie Island data details injury responses of Stellaria media and native plant species to herbicide treatments. The dataset comprises four files from three controlled experiments, measuring injury scores, seedling emergence, leaf counts, and dry weights. Research was conducted at the University of New England, with data published in 2018.
Four files contain data on seedling emergence for Stellaria media on Macquarie Island. The dataset includes plot maps for three sites and a data file with percentage vegetation cover in 15 plots per site, plus seedling emergence counts after one and two months following three vegetation clearance treatments. The data was last updated on March 28, 2016, and originates from the Australian Antarctic Data Centre.
Experimental data from 2016 documents the regrowth and emergence of the weed Stellaria media after applying physical control methods. The study, conducted by the Australian Antarctic Data Centre, involved treatments like hand weeding and scalping across four distinct sites on Macquarie Island. It records percentage cover of the target weed and other species in monitored plots.
Cosmic ray origin neutron count measured from a neutron monitor at Jang Bogo Station, Antarctica. AMD_KOPRI collected this data for studying neutron count variation in the southern high latitude. The dataset was last updated in April 2016.
