In support of the weather component of the NASA Applied Sciences Program, the proposed effort will adapt satellite-derived cloud microphysical products for detection of a recently recognized aviation hazard, jet-engine powerloss in deep convective clouds. As described in a recent Wall Street Journal article, these events have occurred at high altitudes in warm environments and seem to be associated with ingest of high mass concentrations of ice particles into the engine. This hazard is a phenomenon distinct from traditional in-flight icing by supercooled water drops, and is found in different geographical areas and in clouds with different microphysical properties. High ice water contents (IWC) tend to occur near the cores of deep convective clouds. Tropical oceans are a favored location, making satellite data a critical source of observations for diagnosing this hazard. The proposed feasibility study will apply existing cloud microphysical products derived from geostationary and polar orbiting satellite sensors for the detection of high IWC regions. Fields produced by the Visible Infrared Solar-infrared Split-window Technique (VISST) including ice water path, hydrometeor phase, cloud top height, and cloud top temperature are of potential value for this application. In conjunction with two field campaigns targeting high IWC regions, these products will be assessed for utility in detecting the hazard and will be applied to determine the extent of the hazard. Analysis of this data set will allow characterization of the engine powerloss risk in terms of likely locations, frequency, duration, and associated meteorological conditions, thereby contributing to the development of operational products. These products, drawing on data from both geostationary and polar-orbiting satellite platforms, would provide hazard information in the form of gridded data sets in support of the Next Generation Air Transportation System (NextGen).
