From the Hydrology and Remote Sensing Laboratory of the USDA Agricultural Research Service (ARS) comes the ARS Water Database Web site. The database is a collection of precipitation and streamflow data from small agricultural watersheds in the United States, including variable time-series readings sufficient in detail to reconstruct storm hydrographs and hyetographs. Users can choose from any US...
The Arizona Meteorological Network (AZMET) provides air and soil temperature, humidity, solar radiation, speed and wind direction, and precipitation data from 1987 to the present. The website provides the latitude, longitude, and elevation and a map of data collection sites. Researchers can find hourly and daily raw data as well as summaries of weekly, monthly, and yearly data. Although developed...
The latest releases from the National Aeronautics and Space Administration's (NASA's) Earth Observatory include an eight-day composite map illustration showing the maximum snow cover in North America during the period March 5-12, 2000. The data were obtained using MODIS, a sensor aboard the Terra spacecraft. "When compared to the snow extent during average years, it is apparent that there was...
The National Aeronautics and Space Administration's Goddard Institute for Space Studies has two datasets of monthly and annual anomaly precipitation analyses available online. The data sets have a resolution of 2.5 deg x 2.5 deg. The first data set contains data from January 1900 to December 1988 obtained from the DOE. The second data set is an update of the first set and contains data from 1850...
Truly living up to the title of America's First Cloud Physicist, Wilson Alwyn Bentley grew up on a small farm in Vermont, and had a love of knowledge instilled in him by his mother from a young age. As a boy he developed an intense passion for studying and observing water in its many forms. After spending a period of time drawing snowflakes, he began to take photographs through a microscope....
The National Center for Atmospheric Research supplies four types of real-time weather data: satellite, radar, surface, and upper-air. In the satellite link, users have the choice to view images in either one of five wavelengths or one of the three multi-spectral assemblages. The images can also be viewed by the latest image, small loop, or a large loop. The WSR-88D radars provide images with...
