Data Sources for Physical and Earth Sciences

The National Climatic Data Center (NCDC) maintains the world's largest archive of climate data. Types of datasets available include: land-based, marine, model, radar, weather balloon, satellite, and paleoclimatic.

Easy access to climate data. Click "Maps & Data" tab to explore interactive maps.

Weather and crop data published weekly by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, and the U.S. Department of Agriculture.

Daily climatological data (temperature extremes, precipitation, winds) for the United States organized by major airport weather station.

Easy access to weather data for a specific day, with data from 1945 - current.

The ASDC archives NASA Earth science data in the areas of radiation budget, clouds, aerosols, and tropospheric chemistry.

The Atmospheric Radiation Measurement (ARM) Program is part of the Department of Energy and focuses on ground-based observations related to atmospheric radiation, cloud formation, and aerosol interactions.

The National Atmospheric Chemistry Database (NAtChem) contains air and precipitation chemistry data from major regional-scale networks in North America. Datasets include: atmospheric particulate matter and toxic substances, precipitation chemistry data, greenhouse gases, mercury.

The WOUDC contains ozone and UV data measured by instruments located on ground-based, shipborne, and airborne platforms.

CDIAC's data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series.
