The Tropical Atmosphere Ocean project (TAO) website displays real-time data from moored ocean buoys. Information collected includes subsurface, sea surface and air temperature, ocean salinity, wind speed and direction, and short and long wavelength solar radiation data. Such data aid in understanding the unusually warm and cold ocean temperatures in the Equatorial Pacific, referred to respectively ... Full description.

The NOAA Paleoclimatology Program archives reconstructions of past climatic conditions derived from paleoclimate proxies, in addition to the Program's large holdings of primary paleoclimatic proxy data. The site includes reconstructions of past temperature, precipitation, vegetation, streamflow, sea surface temperature, and other climatic or climate-dependent conditions. Users can access air temperature, ... Full description.

This resource is a table for the identification of minerals with a petrographic microscope. The table lists minerals and their properties, including color in thin section, refractive index, extinction and extinction angle, interference figure, birefringence, twinning and other notes. The table is available in html for web viewing and RTF for printing. Full description.

The Oklahoma Mesonet is a network of 110 monitoring stations that measure environmental parameters including air, wind, moisture, soil, pressure, and radiation. Data are available from the Mesonet website as maps, interactive products, public safety indices, weather trends, statistics, meteograms, agricultural models, and summary products. Mesonet data can be displayed using software developed at ... Full description.

This site provides access to real-time oceanographic and meteorological data from approximately 70 moored buoys in the equatorial Pacific Ocean. Data types include wind, air and sea temperature, precipitation, humidity, pressure, radiation, and salinity. The data can be displayed as a summary, time series, latitude/longitude, section, or 3-D animated plot. Data and graphic displays are updated every ... Full description.
