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...

Aircraft inject exhaust particles and water vapor into the upper atmosphere that can produce persistent """condensation trails"""" (contrails) capable of altering the atmosphere's radiative balance and contributing to global warming. The IPCC's recent report, """"Mitigation of Climate Change"""", suggests that aviation may contribute 2-8% of...

The Arctic climate system is experiencing dramatic changes. One of the most dramatic and very public changes is the reduction in the summertime sea ice cover. The IPCC models predict a further decrease in sea ice cover with a potentially ice-free Arctic in 2100 (IPCC...

This investigation will make use of unique NASA observations of cloud properties from A Train instruments to improve decision making for aviation applications. The key instruments to be used include the CloudSat Cloud Profiling Radar, CALIPSO?s active lidar, and Aqua?s MODIS imaging spectroradiometer. The satellite...

This proposal requests funding to leverage NASA assets to continue optimizing a GOES convective initiation (CI) 0-1 hr nowcasting algorithm for performance across various ""convective regime"" types, and to transition the algorithm into a fielded FAA decision support system (DSS). The goal is to use...

Applications of National Priority: Aviation, Energy Management, Air Quality Turbulence is widely recognized as the leading cause of injuries to flight attendants and passengers on commercial air carriers. However, while a state-of-the-art, automated CONUS Graphical Turbulence Guidance (GTG) system has been developed by the Federal...

We propose to develop a prototype Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS) model. The NAIRAS model combines observations of Earth's near-space and atmospheric variables with radiation environment and transport models to provide science results to decision support systems in the aviation area...

To fulfill an objective of the ROSES-2008 A.19, a new application is proposed that will support aviation?s Next Generation Air Transportation System (NextGen), primarily for transoceanic flights where traditional, ground-based data sources are lacking. Satellite-based measurements will be investigated to identify convective hazards and to...
