The U.S. National Weather Service provides anonymous FTP access to files containing collectives of text products generated by various Specialized Forecast Centers and Weather Service Forecast Offices located in the United States, Puerto Rico, and territorial islands in the Antillies and Pacific Ocean. The server subdirectory names and file name definitions can be found with descriptions in the document OSO File Name Standards . The data will be available on the server, as soon as possible, after being received at the Gateway.
Some products are seasonal.
File and Directory Descriptions See Directory and File Naming Standards for information about directory and file name formats. File names in each data subcatagory directory have the format sn. Files are written in sequence with the file sn.0000 following sn.2500 or sooner depending on data type. This scheme provides unique file names for at least the previous 24 hours of data received, as older files are over-written. Data files are written only when data of that subcategory type is available.
