Interactive Forecast Preparation System

IFPS, a new component of AWIPS, integrates the Interactive Computer Worded Forecast (ICWF) software developed by the Meteorological Development Laboratory (MDL) and the Advanced Forecast Preparation System (AFPS), developed by the Forecast System Laboratory (FSL).

IFPS is sophisticated software providing interactive tools which allows users to interpret and edit gridded fields of sensible weather elements. As users prepare these gridded fields of weather elements they are stored in a digital database. Users may initialize these fields of sensible weather elements with any combination of model forecasts, guidance products, or user-generated gridded forecast previously stored in the digital database. The software
allows users to generate products from the digital database in various formats such as tabular, text, graphical imagery and gridded files.

The two primary components of IFPS are the Matrix editor and the GFESuite Spatial and Temporal Editors. For details on the components and use of IFPS, see FSL’s documentation for the GFESuite component. Delivery of the IFPS software and training courses for the AWIPS Release 5.0.IFPS began in January 2001.

Regional IFPS implementation plans are being developed, and Central and Eastern Region have established IFPS Websites with regional time lines for implementation. Check here for a graphical depiction of the National IFPS Implementation. Each region determines the best approach for its offices, and establishes a plan to either focus initially on the use of the IFPS capabilities for graphical and gridded product generation, for routine text and tabular products, or for a combination of both at once. Full nationwide implementation of IFPS is projected to take approximately two years. The goal is to complete the full implementation of IFPS at all WFOs by the end of FY 2003, to achieve the NWS vision to prepare and disseminate NWS forecast products in digital form by 2003.
