This dataset is comprised of various input datasets used to develop ICOADS. Some files are in original native format and other are in the ICOADS binary formats. Note, these data files are not recommended for general use. Individual observations and monthly summary statistics in either a 1-degree by 1-degree or 2-degree by 2-degree latitude by longitude boxes are the recommended user data products. Much more information about ICOADS is available at the project website.
