ISIS provides basic surface radiation data with repeatability, consistency, and accuracy based on reference standards maintained at levels better than 1%. ISIS addresses questions of spatial distributions and time trends at sites selected to be regionally representative and long-term continuous records of observations. The Air Resources Laboratory (ARL) operates the NOAA national broadband solar radiation network, which collects data in both the visible and ultraviolet (UV-B) wavebands. ISIS operates at two levels: Level 1 stations are basic, monitoring incoming radiation only; and Level 2 stations are more fully instrumented, focusing on surface radiation balance (SURFRAD). ISIS Level 1 stations operate in the United States of America. Currently NCDC has in archive data from ten stations located in Albuquerque, New Mexico; Bismarck, North Dakota; Desert Rock, Nevada; Hanford, California; Madison, Wisconsin; Oak Ridge, Tennessee; Seattle, Washington; Salt Lake City, Utah; Sterling, Virginia; and Tallahassee, Florida; from 1995 onward. Major parameters in Level 1 Hourly data are: global and direct beam irradiance, diffuse irradiance, and UV-B global irradiance. To make a wide range of climatic data available to researchers and the public.

Unknown Unknown Solar radiation data are archived by station sort (WBAN number) then date.A. RECORDSThere are two types of records in the database - header and data. Header records precede each stations monthly data. The header records contain information about the site (latitude, longitude, elevation, etc.) and the year and month of the data. The data records are hourly average values sorted by time.
