PIL and WMO Product Details

The data that is received through the Weatherwire system is text based, with headers identifying the type of product, origination, and applicable time period. The current NWWS uses AFOS Product Inventory List (PIL) headers, while the new NWWS will use World Meteorological Organization (WMO) headers. These headings bring weather products into conformance with international standards.

The enhanced capabilities of the new NWWS will allow transmission of limited graphics products in the future. The NOAA Web site provides a format conversion tool for your use as you make the transition between PIL and WMO format.

Note: On October 1, 2001, at 12:30 UTC the National Weather Service discontinued identifying NOAA Weatherwire NWWS products with Product Inventory List (PIL) headers.
