The National Climate Data Center has launched the Climatic Data Online (CDO) system, providing "full period of record digital data for 5 types of US climatic data: daily surface data, monthly surface data, hourly precipitation data, 15-minute precipitation data, and global monthly surface data." Records are available from as early as the late 1800s, and each dataset is updated as more data become available. Data may be selected spatially by region, country, state, climate division, county, and station; and selected temporally (by year, month, day, etc.). Data are organized by space- or comma-delimited format, and can include station name(s) and information if requested by the user. Note that "data are currently provided at no charge to .edu and .noaa users, with charges by credit card for others."
