M2_TMAX_PM25 provides monthly mean surface concentrations of fine particulate matter (PM2.5) aggregated to country and territory levels. The data is a value-added product derived from NASA's MERRA-2 aerosol reanalysis model, calculated as the sum of organic carbon, black carbon, sulfate, sea salt, and dust components. It is produced by the GMAO and distributed via the GES DISC.
SCIOPS leads an international collaboration to measure the time and space structure of large-scale atmospheric waves in the polar mesosphere. Data originates from instruments at Scott Base and the South Pole Station, including a Fabry-Perot interferometer and a medium-frequency wind radar. The study focuses on wave periods from 10 hours to 3 days, covering inertia-gravity and Rossby wave modes.
Monthly head measurements from 21 monitoring wells characterize regional groundwater flow in Wisconsin's Trout Lake area. A concentrated network of 30 wells along a flow path provides high-resolution data on flow paths and velocities. The dataset is part of the Long-Term Ecological Research Program by the University of Wisconsin, Madison's Center for Limnology.
Level 1B radiance measurements from the Cross-track Infrared Sounder instrument on the NOAA-20 satellite are processed via Principal Component Analysis. The data collection includes compressed, denoised radiance values and a Rapid Event Detection product for identifying rare atmospheric signals. It is produced by the GES DISC organization.
Multiple studies from 1998-2000 used portable arrays of seismic receivers to analyze the continental lithosphere. The IRIS PASSCAL program organized these experiments, which utilized both earthquake and explosive synthetic sources. Data is available in IRIS SEGY format for synthetic sources and in tar files with AH traces and SEED format for earthquake data.
Model output data generated for the Intergovernmental Panel on Climate Change's 4th Assessment Report, now known as the WCRP CMIP3 multi-model database. The archive contains subsets of output from 23 coupled ocean-atmosphere general circulation models, including BCC-CM1, CCSM3, and UKMO-HadCM3, across scenarios like 1%/year CO2 increase, 20th Century climate, and SRES A2. The Program for Climate Model Diagnosis and Intercomparison (PCMDI) archives the data, which is hosted on the Earth System Grid portal.
Weekly ice charts from 1966 to 1989 classify sea ice in the Barents Sea into ten categories, ranging from open water to dense pack ice. The data was compiled by the Norwegian Polar Institute and includes raster and vector representations of ice extent.
Continuous time-series data for water levels of large lakes and major rivers, updated operationally within 1.5 days of new satellite measurements. The Hydroweb project from the LEGOS laboratory provides this data, covering approximately 80 large lakes and 300 river measurement points operationally, with research series for about 150 lakes and 1,000 river points.
Data from the Evans Piedmont Glacier, Victoria Land Coast, Antarctica, includes a 180-meter ice core, multiple snow profiles analyzed at 1cm resolution, and three snow pits.
