MYD11C2 Version 6 provides 8-day composite Land Surface Temperature and Emissivity (LST&E) data on a global 0.05-degree Climate Modeling Grid. Each global granule consists of 17 layers, including daytime and nighttime LSTs, quality assessments, observation times, and emissivity values for six MODIS bands. The product was decommissioned on July 31, 2023, with users directed to the updated Version 6.1.
MODIS/Terra Aerosol 5-Min L2 Swath 10km (MOD04_L2) is a satellite-derived atmospheric dataset providing global aerosol properties. It combines retrievals from the Dark Target algorithm over oceans and dark land and the Deep Blue algorithm over all land surfaces, including bright areas like deserts. The data is provided at a 10 km spatial resolution at nadir in five-minute swaths, stored in HDF-EOS format as part of the improved Collection 6.1.
Exmouth Gulf and coastal waters along the west coast of Western Australia from Frazer Island to Bernier Island were surveyed in 1961 by West Australian Petroleum Pty Limited. The reconnaissance marine reflection seismic survey was a two-boat operation using Lorac radio navigation and sextant positioning. Processed magnetic tape recordings were used to construct maps of geological horizons, pre-Cretaceous structure, and water depth.
MODIS/Aqua's MYD04_L2 product provides full global aerosol measurements every five minutes at a 10 km spatial resolution. Its Collection 6.1 version incorporates improved Dark Target retrieval over urban areas and enhanced uncertainty estimates for Deep Blue retrievals. This satellite-derived dataset delivers aerosol optical properties and quality assurance parameters over both ocean and land surfaces.
The MYD11C3 Version 6 product provides monthly Land Surface Temperature and Emissivity (LST&E) values in a 0.05-degree (5,600 meters) Climate Modeling Grid (CMG) covering the entire globe with 7,200 columns and 3,600 rows. It is derived by compositing and averaging daily observations from the MODIS/Aqua satellite and includes layers for daytime and nighttime LSTs, quality control, observation times, view zenith angles, and emissivities from six spectral bands. This dataset was decommissioned on July 31, 2023, and users are directed to use the updated Version 6.1.
Global data from NASA's Aqua satellite provides atmospheric temperature and moisture profiles at 20 vertical levels, total water vapor, ozone content, and three stability indices. Parameters are derived from infrared retrievals at a 5-kilometer pixel resolution for both daytime and nighttime conditions over clear scenes. This Level 2 swath product is produced by the National Aeronautics and Space Administration.
L032 Haddon Downs experimental seismic survey was conducted in South Australia during October and November 1957. The survey, within the Eromanga Sub-basin, recorded two important seismic refractors and indicated a sedimentary section potentially 16,000 feet thick. Preliminary work by Santos Ltd. revealed large surface anticlines.
An experimental seismograph survey near Heywood, Victoria, was conducted in November and December 1956 by the Bureau of Mineral Resources, Geology and Geophysics. Several short traverses tested pattern, air-shooting, and single shot-hole techniques to record reflections through a basalt surface layer. Good reflections were recorded from depths down to eleven thousand feet in areas without basalt, and some poor-quality reflections appeared up to 5 seconds after the shot.
Launched on February 19, 2017, the SAGE III/ISS instrument uses solar and lunar occultation to monitor Earth's atmosphere. The dataset provides vertical profiles of ozone, aerosols, nitrogen dioxide, water vapor, and other trace gases in the stratosphere and mesosphere. These observations are used for long-term studies of atmospheric composition and ozone depletion.
SAGE III/ISS Level 1B Solar Event Transmission Data contains pixel group transmission profiles for individual solar occultation events. The instrument, launched on February 19, 2017 and mounted on the International Space Station, provides long-term monitoring of ozone, aerosols, nitrogen dioxide, nitrogen trioxide, and water vapor in the stratosphere and mesosphere. This data has historically informed World Meteorological Organization assessments of ozone depletion.
Data was collected onboard the NASA DC-8 aircraft during the 2015 deployment of the Student Airborne Research Program (SARP). The dataset likely contains in-situ atmospheric measurements and remote sensing imagery from a flying science laboratory, supporting research in atmospheric chemistry, forest ecology, air quality, and ocean biology. The program provides hands-on research experience for undergraduate students in scientific field campaigns.
NASA's Student Airborne Research Program collected this data onboard a DC-8 flying laboratory during its 2018 deployment. The eight-week internship program, active since 2009, gives undergraduate students hands-on experience operating instruments to sample atmospheric gases and image land and water surfaces. Research areas include atmospheric chemistry, forest ecology, air quality, and ocean biology.
SAGE III/ISS Level 1B data provides monthly vertical transmission profiles of the stratosphere and mesosphere using solar occultation from the International Space Station. The instrument, launched in 2017, measures ozone, aerosols, nitrogen dioxide, nitrogen trioxide, and water vapor to monitor long-term atmospheric composition. This dataset continues a legacy of SAGE missions, with data historically used by the World Meteorological Organization for ozone depletion assessments.
STAQS_Chiwaukee-Prairie_Data contains air quality measurements from the Chiwaukee Prairie site, part of NASA's Synergistic TEMPO Air Quality Science mission. The mission integrates observations from the TEMPO satellite, aircraft, and ground stations to map pollutants like NO2, HCHO, ozone, and aerosols. Data collection was conducted during summer 2023 to improve the understanding of air quality science.
Suomi-NPP VIIRS provides global nighttime sea surface temperature estimates at 750m nadir resolution from thermal infrared observations. The dataset includes a quality flag for each temperature measurement and is designed for near real-time delivery, though inputs may be suboptimal. It is the successor to MODIS for Earth science data products.
Suomi-NPP VIIRS Level-3 Global Binned 11µm Daytime Sea Surface Temperature (SST) Data, version 2016.2 provides global sea surface temperature derived primarily from thermal infrared observations during daytime. The dataset is produced by the Visible and Infrared Imager/Radiometer Suite (VIIRS), a 22-band instrument on the Suomi National Polar-orbiting Partnership (S-NPP) spacecraft launched in October 2011, which succeeded the MODIS sensor for Earth science data. Users apply SST to detect oceanic fronts and eddies, monitor marine heatwaves, and drive ecosystem and climate models.
