National Climatic Data Center — available to everyone!
If you seek reliable climate data, look no further than the National Oceanic and Atmospheric Administration’s National Climatic Data Center (NCDC). With a digital archive that boasts six petabytes of data collected from ships, balloons, weather stations, radar, satellites, and other far-out places, the NCDC provides a wealth of information for interested citizens and serious researchers alike.

Marine biology, meteorology, and ocean engineering students may be particularly interested in the NCDC’s Marine/Ocean Data section, which collects global meteorological data including historical and current observations, sea surface temperature analyses, blended sea winds data and animations, GIS maps, and a whole lot more.
Going on vacation? Planting a garden? Find U.S. Climate Normals and Freeze/Frost data for your U.S. location in the Climate of the U.S. section.

There really is something for everyone here!
