Gateway File Services

Non-Coded Text Message Files
Containing
Warnings, Outlooks, Advisories, Forecast, & Discussions

Introduction

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 messages are in the same format as received from the sources, identified in either standard WMO abbreviated header or AWIPS product identifier message bulletin structure.   The server subdirectory names and file name definitions can be found with descriptions in the document OSO File Name Standards.   The naming conventions for all current subdirectories and files are described in the document titled: File Server Naming Practices.   The data is available at the NWS Telecommunication Gateway on the server ftp://tgftp.nws.noaa.gov via anonymous FTP.

Information Available

There are 125 products listed below that come from our NWS Forecast Offices or the NCEP Special Centers. These products in WMO/AWIPS bulletin message form are scheduled for delivery to the Gateway Switching System for distibution.   The data will be available on the server, as soon as possible, after being received at the Gateway. Some of the listed products are event driven; therefore, some data subcategories do not update too often. Some products are seasonal.

Delivery Details Data files are updated on the FTP server every five minutes or sooner with data from the Gateway. File names in each data subcatagory directory have the format sn.nnnn ; where nnnn is a four-digit number ranging from 0000 upto 0288 in most subdirectories (the upper limit will vary depending upon the data type). Files are written in sequence with the file sn.0000 following sn.0288 as this is the wrap point in the sequence depending on type. Files containing warnings are written more often. 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.
