Monthly data consist of monthly averaged maximum, minimum, and mean temperature and total monthly precipitation from 1221 stations. Data records generally include the period from 1900 through 2006 and are available via a graphical user interface. While these data have been available through the Internet for several years, users typically had to download rather large files that contained one variable for all stations for the entire period of record. While obtaining the data in this manner is still possible, you can also download data for individual variables, from individual stations, for the time period of your choice. You can download and save the data, and also plot data from individual stations in a number of ways, yielding insight into the station's record, and thereby helping to determine the suitability of a station's data for particular applications.
