Potential Upgrades to the Current and Forecast Icing Algorithms

The Current and Forecast Icing Product algorithms generate icing diagnoses and forecasts across the CONUS. These have been approved for use in operational decisionmaking in aviation. However, there is both a desire and need for upgrades to improve accuracy through use of new or improved weather prediction models or observations. This paper describes the upgrades planned at this time and outlines the reasoning behind choosing new candidate information for those upgrades. Two products under consideration for addition to CIP, images from the Advanced Satellite Aviation-Weather Program and grids from the 3-D NexRad radar mosaic produced by the National Severe Storms Laboratory, are described in more detail.
