The second data set is an update of the first set and contains data from 1850...

The Snow Crystals Web site was created by physics professor Ken Libbrecht from the California Institute of Technology. Visitors get to explore how snow crystals are created and their structure. The main page describes natural and designer snowflakes, which are created in the laboratory, along with dozens of spectacular photographs. The author also details and illustrates the crystalline lattice...

Although the Space Environment Center's database has been mentioned previously in the Scout Report (see the May 13, 1994 Scout Report), it is worth mentioning again because an unusually large amount of solar flare and geomagnetic activity has occurred in recent weeks. At the Space Environment Center site, the National Oceanic and Atmospheric Association (NOAA) posts data, some of it updated by the...

Housed at the Cooperative Institute for Meteorological Satellite Studies (SSEC) at the University of Wisconsin - Madison, the atmospheric emitted radiance interferometer (AERI) "measures downwelling infrared radiation from 3-25 "m at less than one wavenumber resolution every ten minutes." Users can learn about the instrument's many applications including atmospheric profiling and cloud data...

A constituent of the University of Virginia, the Virginia State Climatology Office provides information on the atmospheric environment and analyzes the effects weather and climate have on the economic and ecologic systems. Researchers can find information on how to obtain climate and weather data and can view meteorological maps as well as links to various radar and satellite images. Students can...

The Washington Post makes a bid for the already crowded Internet weather market with WeatherPost. Coverage includes current conditions and four-day forecasts for 3,600 cities worldwide, as well as snapshot and time-lapse satellite maps (provided by Accu Weather). For US cities, users may also access UV and air quality maps and data, as well as seasonal maps (snow cover, tanning index, heat index,...

The National Oceanic and Atmospheric Administration (NOAA) provides these two Websites on weather. The first site serves as a major hub for information related to weather, with links to primary data sources, forecasts, maps, images (such as the latest satellite imagery for North America), and a wealth of other data, including space weather. Researchers will also find links to national weather...

Created by the Stevens Institute of Technology, the Wonderful World of Weather is a standard-based real time data module for elementary students to explore weather phenomena locally and globally. Teachers can find many fun classroom activities divided into three sections: introductory activities, real time data activities, and language arts activities related to weather. The website features an...

WorldClimate.com contains data "that are historical weather averages, showing what the weather was typically like each month, averaged over a range of years." Simply enter a city to obtain a list of matching entries; then click on the desired one and up comes all available data. This could include average precipitation, average maximum and minimum temperature, heating and cooling degree days,...
