Book Description
A ground-based system has been developed to demonstrate the feasibility of automating the process of collecting relevant weather data, predicting wake vortex behavior from a data base of aircraft, prescribing safe wake vortex spacing criteria, estimating system benefit, and comparing predicted and observed wake vortex behavior. This report describes many of the system algorithms, features, limitations, and lessons learned, as well as suggested system improvements. The system has demonstrated concept feasibility and the potential for airport benefit. Significant opportunities exist however for improved system robustness and optimization. A condensed version of the development lab book is provided along with samples of key input and output file types. This report is intended to document the technical development process and system architecture, and to augment archived internal documents that provide detailed descriptions of software and file formats.Hinton, David A.Langley Research CenterESTIMATING; ALGORITHMS; AIRCRAFT WAKES; DATA ACQUISITION; ROBUSTNESS (MATHEMATICS); PREDICTIONS; DATA BASES; VORTICES; SPACING; FORMAT; FEASIBILITY; ARCHITECTURE (COMPUTERS)

Book Description
In support of NASA Virtual Airspace Modeling and Simulation (VAMS) project, an effort was initiated to develop and test techniques for extracting meteorological data from landing and departing aircraft, and for building altitude based profiles for key meteorological parameters from these data. The generated atmospheric profiles will be used as inputs to NASA s Aircraft Vortex Spacing System (AVOLSS) Prediction Algorithm (APA) for benefits and trade analysis. A Wake Vortex Advisory System (WakeVAS) is being developed to apply weather and wake prediction and sensing technologies with procedures to reduce current wake separation criteria when safe and appropriate to increase airport operational efficiency. The purpose of this report is to document the initial theory and design of the Aircraft Approach Departure Atmospheric Profile Generation Algorithm.Buck, Bill K. and Velotas, Steven G. and Rutishauser, David K.

Book Description
The book is a collection of the lectures delivered during the 7th International Summer School on Atmospheric and Oceanic Sciences (ISSAOS) titled “Integrated Ground-Based Observing Systems Applications for Climate, Meteorology, and Civil Protection”. Its aim is to contribute to the scientific understanding of basic concepts and applications of integrated ground-based observing systems. The first part describes the most common instrumentations showing their strengths and limitations. Furthermore, strategic plans for the deployment of an observation site are discussed along with an overview of techniques for integrating heterogeneous data. The second part introduces cutting-edge applications, including assimilation in numerical weather prediction, climate benchmarking, air quality monitoring and meteo/hydrological warnings.
